Re: Getting "Expected input credential was not present" error when tried pullfundstransact

Hi akshaymhatre,

 

In order for us to further investigate the Foreign Exchange Rates API issue, can you please provide more information on the error you have received? Please send the response request of the error received, screenshot and the Correlation ID. Please let us know if you have other questions.
 
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>Then try to click on the add API link.
5>You can find the Correlation ID in the network log for add API call.

 




Thanks,

Diana

I was able to resolve this. Had to make a few changes in the delegate method for didReceiveAuthChallenge() in my app.

There is no sample project for Swift/iOS in the getting started guide. Let's get together and put one out there.

Hi @akshaymhatre,

 

Thanks for sharing with us your success in resolving the issue! Can you please let me know what were the few changes that you did in the delegate method for didReceiveAuthChallenge() in your app?

Re: Getting "Expected input credential was not present" error when tried pullfundstransact

The didReceiveChallenge method is invoked twice with different authenticationMethod.

Once with NSURLAuthenticationMethodServerTrust and second time with NSURLAuthenticationMethodClientCertificate.

I needed to pass the p12 certificate bundle for the NSURLAuthenticationMethodClientCertificate challenge.

For NSURLAuthenticationMethodServerTrust, had to do the performDefaultHandling.

Re: Getting "Expected input credential was not present" error when tried pullfundstransact

Hi @shminerve,

 

The Visa Payment Processing Authorization API requires Message Level Encryption (MLE). Please ensure that you are encrypting the request payload with the proper MLE credentials. 

 

Please refer to the MLE resources in the below links:

Documentation: https://developer.visa.com/pages/encryption_guide

 

Tutorial: 

https://community.developer.visa.com/t5/Message-Level-Encryption/How-to-run-MLE-Sample-Code-Project/...

 

Hope this helps, please reach back out with any further questions.

 


Best,
Stacey

Re: Getting "Expected input credential was not present" error when tried pullfundstransact

Hi, i solved decrypting issue (thanks for your help).

Now i'm trying to call this endpoint : https://sandbox.api.visa.com/acs/v2/payments/authorizations/voids , i'm getting

[details] => Array
(
[message] => Error in processing request, Please Contact Visa Inc.
)
[status] => 404

The decrypting JJWE is sucess, i don't undersstand 404 ERROR (i'm using this doc : https://developer.visa.com/capabilities/vpp/reference#tag/Authorization-API_/paths/~1acs~1v2~1paymen...

Thnaks for your help again.
