Azure B2C - Custom Policies - Sign In journey - pass user data to REST APIs

Question

Hello Microsoft Community,

Currently, we have implemented TechnicalProfile of REST API which passes user attributes to an external endpoint in the Sign Up phase. But now we want to have the same in Sign In phase. I tried to copy/paste the TechnicalProfile with the new entries. But what should be the next steps? I'm stuck with this configuration and I can't find much information on the web on how to proceed further. I will appreciate your help!

Best Regards,
Bogomil

Hello JamesHamil-MSFT, thank you for reaching out. I was following these tutorials/docs:

https://learn.microsoft.com/en-us/azure/active-directory-b2c/restful-technical-profile
https://learn.microsoft.com/en-us/azure/active-directory-b2c/api-connectors-overview?pivots=b2c-custom-policy
https://learn.microsoft.com/en-us/azure/active-directory-b2c/add-api-connector-token-enrichment?pivots=b2c-custom-policy

I will share more context about my issue. We have a CRM integrator/endpoint hosted on function app. After a new user's "SignUp" in Azure B2C we make an HTTP POST request to that endpoint, and CRM receives user data. This solution works.

We want to make an HTTP GET request after the user's "SignIn". I tried to edit B2C_1A_TRUSTFRAMEWORKEXTENSIONS.xml policy following the tutorials but without success.

I'm getting this error after user SignIn - The claims exchange 'REST-CRMGetUserInfo' specified in step '7' returned HTTP error response with Code 'BadGateway' and Reason 'Bad Gateway'.

Hello, @James Hamil ,

you can close the question/issue. We found a way to pass parameters to an external REST API following the documentation and testing after each step.
