Hi @ asraro,   Thank you for the inquiry. The error 400 - 9124 Expected input credential was not present usually occurs when the credentials used are invalid. Can you please confirm if you are using valid credentials? Also, please double check the SSL settings and make sure the keystore has all the necessary certificates imported. To start, this error usually occurs when your certificates are not sent. · Keystore is not setup.

Hello globalsolut ,   To what I know is that IAT number is assigned to the billing entity. Let’s say if you have to wire the money into someone’s account, the billing company should give you the information like Account number and IAT number. I can’t be very sure on this but usually this is what I have seen.   Since we are a developer platform, not a financial institution, I would recommend you do some research online or follow up with the issuing banks in obtaining the IAT/ICA Number.   However, I will continue to research within and will update you if I find any information.   ...

Hi @ devin ,   The 401 Token Validation Failed error you're getting will be seen when the x-pay-token sent in the header is invalid.   A couple of things I'd like you to note while generating the token:   1. To start, please follow the Working with Visa APIs > Authentication > X-Pay Token guide to generate a valid token. https://developer.visa.com/pages/working-with-visa-apis/x-pay-token   2. APIkey in the url query param should be the same as the one used to generate xpayToken   3. “resourcePath” sent in the xpaytoken has to be as per the documentation (eg: v2/payments?apikey={apikey}).   4. Payload sent in the request payload should exactly match along with spaces to the “requestBody” value used in xpaytoken.   Can you please provide the request payload of this API call? It's possible that you're missing a field or have an inaccurate format. I'd like to see screenshot attachments of the error provided, if possible.   Also, could you check to see if you're passing a correct value for URI. For example, make sure it’s defined correctly in the beginning of your code, and use the same value for the URI in the middle of your code. In general, for cases like this (i.e. “helloworld works, but the API XX doesn’t”) I'd like to ask of you, if you could, to please extend your SOAPUI project, and make sure that you can call a particular API from SOAPUI project first.                               ...

Hello sherloc987 ,   Thank you for your inquiry. Can you please make sure you are using the right credentials, such as username and password?   In addition to that, the issue could also be caused by the Certificates not being sent with the request. Check File->Settings->SSL Settings and make sure the KeyStore and KeyStore Password are populated in Soap UI.     The Certificate Signing Request is a prerequisite to get your application certificate (cert.pem), which is required to establish a two-way SSL connection. Additionally, you will need a root certificate (VICA-SBX.pem) and your private key.   You have two options to generate a Certificate Signing Request (CSR):   Have Visa generate a CSR for you Select "generate a CSR from me" when you create a new Visa Developer application. When you select this option, Visa will generate a CSR for you, and you will be prompted to save your private key file when it is downloaded through your browser. Once you save your private key, go to your Visa app page and download your client certificate (cert.pem), as well as your root certificate (VICA-SBX.pem). You will then have everything you need to create a key store.   Generate your own CSR You can choose to create your own CSR. The Visa Developer Getting Started Guide provides detailed steps on how to generate CSRs: https://developer.visa.com/pages/working-with-visa-apis/two-way-ssl. Please note that you have to fill out all required fields in your Certificate Request. Also, note that the organization name and unit fields do not accept punctuation characters – your CSR will be deemed invalid if you use these characters. Once you have a CSR file, go ahead and create a Visa app, choose "Submit my own CSR", and upload your CSR file. During the CSR creation process, take note of the file containing your private key. Once you upload your CSR, go to your Visa app page, and download your client certificate (cert.pem), as well as your root certificate (VICA-SBX.pem). You will then have everything you need to create a key store.   Continuing to the Key Store Once you have a private key and two certificate files in your local directory, you will need to combine them into a key store. You can decide whether to use Java Key Store (JKS) or PKCS (P12) key store, depending on what your development environment requires. There are sections in “Getting Started with Visa Developer” > “Two-Way SSL (Mutual Authentication)” (https://developer.visa.com/pages/working-with-visa-apis/two-way-ssl), that describe how to create each type of key store, please follow those steps. Note, that the root certificate is not needed for a P12 file, you can create a P12 file out of two files: private key and cert.pem   If you continue to get this issue, please provide us the correlation ID and we can further investigate the issue.   Below are the steps to get the Correlation ID using a Google Chrome browser. 1>Open Chrome menu. 2>Click on More tools then Developer tools. 3>Check the box to Preserve Log for the Network Tab. 4>Click on the error and go to the Headers. 5>You can find the Correlation ID in the network log.   Please perform these steps and let me know your findings. ...
