Recently, I ran into this error message in Salesforce where it stated that “LOGIN_MUST_USE_SECURITY_TOKEN Invalid username, password, security token; or user locked out. Are you at a new location? When accessing Salesforce–either via a desktop client or the API–from outside of your company’s trusted networks, you must add a security token to your password to log in. To get your new security token, log in to Salesforce. From your personal settings, enter Reset My Security Token in the Quick Find box, then select Reset My Security Token.” According to the official Salesforce documentation about User Authentication, there are two major ways to log in to the Salesforce via the API. One way is to use your Salesforce credential along with your security token. Here is an example of how to do it, If a user’s password is mypassword, and the security token is XXXXXXXXXX, the user must enter mypasswordXXXXXXXXXX to log in. Source Another way is to simply use your Salesforce credential to log in to the Salesforce. However, you must whitelist your server IP address in your Salesforce’s Network Access page. Otherwise, you might get error message like I mentioned earlier. To get to the Network Access page, simply head over to your Salesforce dashboard and go to Setup->Administration Setup->Security Controls->Network Access. One of the biggest differences that I can see between them are the origins of the request. The first way allows you to send SOAP API request to Salesforce with unknown origin as long as you provided your own security token. This is especially useful when your application does not have fixed server IP address. In contrast, you must whitelist your server IP address in order for second way to work. This can be useful when you have lost your security token but were unable to retrieve them nor to reset them. For a long time, the form that I wrote that integrates well with Salesforce been working for almost 3 years till recently it started to break. I asked the company whether or not did they switch to a new web hosting provider. They answered no. Then, I got hooked. How is it even possible that you guys receive the error message LOGIN_MUST_USE_SECURITY_TOKEN when you guys did not change anything at all? I feel that it is just not possible. Something must have changed. And, I was like “Great, now is a perfect time for me to show off my debugging skill. Let’s do it!” Thanks to Salesforce, it logs pretty much everything about what an user do on their Salesforce account. I was able to go through the API access log and to see what has changed in the past 6 months. And guess what I saw, the day that the form broke, was also the same day that the server IP address changed. But who changed it if not the own company? I think you can guessed who. It was the web hosting provider. Yuck! I was wondering, why didn’t we get any friendly warning about that. That is just not right. Now that I have found the root cause of the problem, like I mentioned above, I simply need to head over to the Network Access page, and add that new server IP address to the list and everything should be back to normal now and it did. Now, the form started to work again. = However, I still think that a better fix for this problem would be to use security token along with your Salesforce credential to log in to the Salesforce via API so that even when the web hosting provider changed their server to a new one. The form will still works which is something that I am working on right now as we cannot let these things happen again in the future. Now, you should be able to go ahead and make that error message go away= Wrapping Up Hopefully you enjoyed this short tutorial. Let me know if this helps you. Thank you for reading!

Adversariesmay duplicate then impersonate another user's token to escalate privileges and bypass access controls. An adversary can create a new access token that duplicates an existing token using DuplicateToken(Ex).The token can then be used with ImpersonateLoggedOnUser to allow the calling thread to impersonate a logged on user's security context, or with I'm trying to use the Microsoft Graph API to query an Outlook/O365 mailbox for messages. I registered my app in the Azure portal and received the necessary information to query the API. The app has the permission. I don't have access to the Azure portal, I was told it was set up this way. When I get my token from the OAuth endpoint, however, it doesn't work in any subsequent calls. I'm using Python's requests module for testing right now. Why is this call failing? It seems like I'm passing all of the correct information but I'm clearly missing something.

I was trying to build an Azure Function with the ability of accessing Microsoft Graph API. Imagine, this function must trigger every night and pickup some emails and organize them in to a folder. So there shouldn’t be any user interactions right. You just can’t got every night and login using your credentials and then let the function you know, Microsoft Graph API require a “Bearer” access token to make a successful call to the API, else and Access Denied 401 Unauthorized is thrown. The request header must have a “Bearer” authorization token to make a successful call. And this token must be valid way of doing this isCreate a login using your Work, Office or Personal Microsoft the Access the token and call Microsoft you look at the above scenario we can’t login to the system and it should be a silent login. And there shouldn’t be any user interaction to do this. But if you could skip step 1 and 2 and straight away get the token? Yes you can and let’s find out how to do will be looking at completing these stepsCreate an Azure AD Application in your some permissions to the application for accessing Microsoft an admin account consent on behalf of their a password a key for the code using these information to get an access Azure AD ApplicationLets goto your organizations active directory, by following this URL successful login will bring you up the AAD admin Admin PanelNow in the left side pane click the label “Azure Active Directory”Azure Active DirectoryThis will open up the blade for Azure Active Directory. In that screen should see a label “App registrations”. This is the starting point of a registering an Azure AD registrationsThis blade will allow you to create a new application for Azure AD. Lets have a look on the AD Application RegistrationAs you see, might get a bunch of apps already have, and a button on the top “New registration”. Let’s click on that button to create a new application registrationNow you will see the new application registration application registrationName → This will be the name of your application. In this case, I have given “NodeJS-Tutorial-App”. Of course it’s up to you to choose name for your app. If it’s already there, don’t worry Azure is smart enough to let you account types → This section will restrict the access. The options are in this organizational directory only — Only users of your organization can access the resources using this in any organizational directory — Anybody who has a Microsoft work or school account can access APIs that allowed to your in any organizational directory and personal Microsoft accounts — This will allow anybody who has a Microsoft live account, work or school account can use your application to access allowed APIs to that have chosen the third option. And again it is all up to URI → We don’t really worry about this part, cause we don’t accept any redirection to our app after login. But I have given a value as localhost3000Now let’s hit the “Register” button. And you should see the newly registered applications is createdNow you have to note down few things here. We will be using these to build our client ID → The id of your application Directory tenant ID → The Azure AD tenant idNext step is to get the token endpoint. This end point will generate the token for you. Generated token from this endpoint will be used to access Microsoft Graph API on the “Endpoints” button on the top of the buttonThis will get all the endpoints for your application. Make sure you copy down the endpoint for OAuth token endpoint v2OK, lets have a look on the next stepAllowing permissions for Microsoft Graph APIIn the “NodeJs-Tutorial-App” application blade, click on the “API permissions” permissions for Azure AD ApplicationAs you see, Azure has already given you “ delegated permissions for your application. This permission will allow us to read user information for a logged in user. These are Microsoft Graph API permissions, in other hand we can call them as “Scopes”.Have a read here for the full list of scopes for Microsoft Graph I mentioned before there are two methods of permission types can be used with an Azure AD You will use this application on behalf of a user. For an example, if I logged in using my Work or School account, I am allowing this application to use my credentials on behalf of give the permission to this specific app. No user is now, you must have realize what type of permissions we need use to get a token for Microsoft Graph API. Yes, you are correct we need “Application” on the available “ permission and delete permissionNow, click on “+ Add a permission” button and select “Microsoft Graph”Select Microsoft Graph permissionClick on “Application permissions”. Now you see a list of permissions available for Microsoft Graph permissions for Microsoft one or more depending on your need, click “Add permissions” admin consentWarning of admin has to consentDid you see the WARNING!!!?. Don’t worry and means an admin of your organization must allow this application to access the selected permission on behalf of the click “Grant admin consent for ” has granted consentExcellent, you are almost a key password for the applicationLet’s create a key for the application. Since we are not going to interact with any of the users. We need this key. Let’s create one. Click on the “Certificates & secrets”Certificates & secretsNow click on the “+ New client secret” and give a name and select an expiration a keyAnd click “Add”, and make sure you have copied the key down. When you go away from this screen. Azure doesn’t allow you to see this key generated keyExcellent, now you have everything to get the token using a do a checklistApplication ID → ✔️Tenant ID → ✔️Application permissions → ✔️Token Endpoint → ✔️Admin grant consents → ✔️Generate a client key and copy it down → ✔️Now you can use favorite language to generate this simple app to get the tokenFire up your favorite shell and create a directory and go inside it. Execute the following command.$ npm init -yNow you should have a simple node application. Again type the following command to create the “ touch open up your favorite editor or just type the following command. I am using Visual Studio Code. Grab it from here $ code .Now select the “ and create these constants at the top of the APP_ID = '[COPIED_APP_ID]’;const APP_SECERET = '[COPIED_APP_SECRET]’;const TOKEN_ENDPOINT =' MS_GRAPH_SCOPE = ' you see MS_GRAPH_SCOPE will hold the scope given to your application. These scopes were given at the time we created the Azure AD application we need to access the token endpoint and create the token. For that we can use the built-in http module in node or we can use a third party npm package. I have used axios here. You can read the full documentation about axios visiting this install the axios i axiosAnd again we need another npm package that will stringyfy the post data. This library will create a proper JSON string from the object you pass. Let’s install that i qsLet’s go back to our editor and add the following code below the constants the we have axios = require'axios';const qs = require'qs';Finally add this codeAs you see in the line 1 to 6 we have created the body for the POST request sent on line 11. The information and the “key” names must look like in the code. And the post content type must be application/x-www-form-urlencoded’.Rest of the code is full code should look like lets do a test$ node You should see an output like thisGenerated access tokenThats it folks. Enjoy.

Did your credit card get declined when you tried to use it? Are you wondering if the reason for your blocked transaction was because you’re out of funds or for location restrictions? Or something else? With this list of credit card declined codes, you can determine the source of the problem. In this article, we’ll help you figure out exactly what’s going on with your or your customer’s credit card and why the transaction didn’t go through. We’ll cover all standard — and less common — credit card declined codes in detail, including what they mean and what you should do about each one. Let’s go! Check Out Our Video Guide With a Complete List of Credit Card Declined Codes Explained What Is a Credit Card Decline Code? A credit card decline code is the code that appears on a credit card processor when a transaction, or payment, has been declined. If you’re in a store and can’t get your credit card to work, you and the vendor will get an error that can direct you to what went wrong. You can also get error codes when trying to make online purchases. Example of a declined online credit card purchase Source This can happen whenever a transaction is stopped by the vendor, bank, or card issuer. When you have this issue, you’ll get a short error message of one to three numbers or letters, in some cases. This error message is what’s known as a credit decline code. The code can explain what the actual issue is… as long as you know what it means. First, we’ll cover some of the most common reasons a card is declined — and the relevant codes associated with them — before doing a deep dive into all potential credit card decline codes. If your customers see one of these codes when attempting to check out on your site, learn what could be causing it with this guide ✅Click to Tweet Most Common Reasons a Card Is Declined First off, let’s start by covering a few common reasons that a transaction might be declined. The problem can be something as simple as the payment processor struggling with your card, insufficient funds, or an electronic issue connecting with your bank or credit card company. Some of the most common card decline reasons include Credit card verification error Code CV There could be an issue with your card’s microchip or magnetic strip, making it impossible to use for transactions. Insufficient funds Code 51 You don’t have enough money in the accounts associated with your card both credit and debit cards. Exceeded credit limit Code 65 Even if you have money in your accounts, you need to pay it down if you’ve exceeded the credit limit for the card before you can use it again. Expired card Code 54 All credit cards have an expiration date, and trying to use a card after that date will give you an error message. Transaction not permitted Code 57 This occurs when you try to use your card for a transaction that is not allowed for example, if you’ve blocked online transactions or international payments. Wrong card number Codes 14 & 15 There are two wrong ways to enter the card number improperly. If the very first digit is incorrect, you’ll see error code 15 for “no such issuers” since the first digit pinpoints the card’s issuing bank. If you get any other wrong numbers, you’ll get error code 14 for entering an invalid card number. Wrong security code Code 63 This occurs when you type the three-digit CVV or CVC code on the back of your card or the four-digit CID code on the front of your card incorrectly. Examples of where to find your CVV, CVC, or CID number Source LendingTree For many of these issues, you may also see error code 12 or error code 85. These simply denote an invalid transaction. Credit card issuing banks often use these two errors as catch-all response codes, making it harder to know what’s wrong. You might have mistyped a credit card number, used the wrong verification code, entered an invalid expiration date, or attempted something inherently impossible, like trying to refund a refund. If you didn’t see your error code in this section, you could browse the table below, which includes over 50 credit card decline codes in numerical order, along with details as to why each code happens and how to fix the problem. Complete List Credit Card Declined Codes This table includes a list of all credit card error codes, exactly what they mean the actual problem, and how to fix them. Code Label The Problem The Fix 01 Refer to issuer The issuing bank Mastercard, Visa, Discovery, etc. prevented the transaction without a specific reason. Call the bank and ask them to explain the issue. 02 Refer to issuer special condition The customer’s bank prevented the transaction similar to code 01. Use the number on the card to call the bank and ask for an explanation. 04 Pick up card, hold call no fraud implied The customer’s bank prevented the transaction and is also telling the merchant to hold the card. This doesn’t imply fraud, but rather overdrawn cards or expired ones. Call the bank to ask why the pick-up notice is showing up for your credit card. 05 Do not honor The customer’s bank stopped the transaction and told the merchant to “not honor” the card not to accept payment. Call the bank and ask for an explanation. 06 Other error The issuing bank can’t specify the error, but something went wrong with the transaction. Try again, and call the bank if the issue persists. 07 Pick up card, special condition fraudulent The customer’s bank stopped the transaction because the card or bank account has been flagged as fraudulent. If you’re the customer, call the bank immediately to clear up any potential issues. If you’re the merchant, withhold the card until you can gain confirmation from the bank and customer about their identity and the card’s legitimacy. 10 Partial approval The issuing bank accepts a part of the payment but blocks the rest, typically due to exceeding the credit limit or funds in the account. Call the bank to clear up the issue and pay down your credit if the credit limit is the issue. 12 Invalid transaction The transaction attempted is invalid. This could be due to any number of faulty operations, including trying to refund a refund. Before you call the bank, restart the transaction from scratch, and make sure all the information entered is correct. 13 Invalid amount The amount you entered for the transaction was invalid, usually due to a non-numerical symbol being entered along with the amount a dollar sign. Simply start the transaction over again and be careful to avoid using symbols when typing the amount. 14 Invalid card number The card number is invalid, and the credit card processor can’t find the related account. Start the transaction over again, and be careful to enter the digits accurately. If the issue persists, call the issuing bank. 15 No such issuer The first digit, which identifies the card’s issuing bank, was incorrect. Credit card-issuing banks have their own unique code that starts with the first digit — 3 for American Express, 4 for Visa, 5 for Mastercard, or 6 for Discover. Carefully type the credit card number again, making sure to include the first digit correctly. 19 Re-enter An unknown error occurred. Restart the transaction and be careful to enter all the information correctly. If the issue persists, call the card issuer. 28 No reply/response An error occurred during the transaction without the reason specified. Restart the transaction and be careful to enter all the information correctly. If the issue persists, call the card issuer. 41 Lost card, pick up The card’s legitimate owner has reported it lost or stolen, so the card issuer has denied the transaction. If it’s your own card, you need to call the bank right away. If you’re the merchant, ask the customer to use an alternate card or contact their bank. 43 Stolen card, pick up fraud account The legitimate owner has reported the card as stolen, so the card issuer denied the transaction. If it’s your own card, you need to call the bank ASAP with the number on the back of the card. If you’re the merchant, ask them to use an alternate card or contact their bank. 51 Insufficient funds The card issuer is blocking the transaction because the account has already exceeded the credit limit, or the pending transaction would put the card over. Contact the bank with the number on the back of the card, use online banking to transfer funds to the card, or use an alternate card. 54 Expired card The expiration date has already passed. Use a credit card that is still valid. If you only have one, the new card should typically have arrived in the mail before the old one expires, so be sure to contact the bank. 57 Transaction not permitted – Card This code shows up when you’re trying to use a card for a transaction that’s specifically not allowed, like transferring funds to a foreign merchant account. Use an alternate card without such limitations, or call the issuing bank to clear up whether you have the option to allow such transactions. 58 Transaction not permitted – Terminal If the merchant account connected to the terminal or payment processor is not properly configured, you’ll see this error. The merchant needs to call their bank to clear things up. If you’re the customer, use an alternate payment method, like cash or check. 62 Invalid service code, restricted The invalid service code can refer to two specific You’re trying to process an American Express or Discover card, but the system doesn’t support those card issuers. 2 You tried to pay for online purchase with a card that doesn’t support online payments. Try a credit card from a different issuer, like Visa. If the merchant advertises accepting payments from your card issuer, you need to contact the bank to ask about your card’s configuration for online payments. 63 Security violation The three-digit CVV2 or CVC or the four-digit CID security code was incorrect or wasn’t read properly. Restart the transaction from scratch and carefully type the correct security code. 65 Activity limit exceeded The credit card user has exceeded the credit limit or this transaction would put them over. Use another credit card. If you have no other cards, you can use online or telephone banking to pay down the card before you try it again. 85 or 00 Issuer system unavailable This error code shows up when there’s a temporary communication error between the merchant and the issuing bank. Wait a few moments, then start the transaction over from scratch. 85 No reason to decline The issuing bank can’t identify a specific problem, but the transaction still didn’t go through. Start the transaction again from scratch, and if the issue persists, call the issuing can also try using another credit card to see if the issue is merchant-specific. 91 Issuer or switch is unavailable The terminal or payment processor was unable to complete the payment authorization. Start the transaction from scratch, and if the problem persists, call the issuing bank. 92 Unable to route transaction The terminal cannot reach the card issuer to process the transaction. Wait a few minutes and try again. If the issue persists, contact your bank. 93 Violation, cannot complete The issuing bank has recognized or has been informed of a legal violation on the part of the credit card user, and assets have been frozen. If you mistakenly get this error code, call the issuing bank right away to clear up any issues. 96 System error There’s a temporary issue with the payment processor. Restart the transaction. If the issue persists, try another credit nothing works, it’s likely an issue with the merchant’s payment processor. RO or R1 Customer requested stop of specific recurring payment Your customer has specifically asked to stop the recurring payment you’re trying to process. First, cancel all scheduled future payments to avoid chargebacks and related the customer is in breach of contract, you’ll need to get in touch with them to clear things up. CV Card type verification error The card reader had a problem verifying the card. This could be an issue with the microchip or the magnet strip. Try the age-old trick of wiping the credit card against your shirt and carefully swiping it that doesn’t work, key in the number or contact the issuing bank. W1, W2, W9 Error connecting to bank This can happen because of a power or service outage. Wait for the power to come back on, or look for news of local outages that might affect there isn’t any apparent reason, contact your merchant bank.
