Capture Form Post Data that Pega receives from another Application.
We are using OIDC Authentication in Pega, but there is an another Application(Non-Pega), which you have to come through to access Pega Pages.
Here there is an additional set of Request that the application is sending to Pega in the Form Data as part of the payload. So here How can we capture the Request in Pega?

@AkshithReddyTTo capture form post data sent from another application to Pega while using OIDC authentication, you can extend the Authentication Activity (like pyOAuthOIDCAuthenticate) to capture the incoming request data. Use the pxRequestor.pyHTTPInformation or pxHTTPServletRequest page to extract the form data. For example, you can use tools.getParamValue("FormParameterName") or access the raw request data with tools.getRequestor().getServletRequest().getReader().lines().collect(Collectors.joining()). The captured data can be mapped to a Data Page for further use in the application. If the data is part of the OIDC token, override the pyCaptureOAuthData activity to handle it. Ensure the Service Package is correctly configured to accept requests, and validate the data for security purposes. Use Tracer to test and verify the incoming data capture during authentication

@Sairohith I don't see any pyOAuthOIDCAuthenticate Activity and tried the pxHTTPServletRequest, but it seems there is no object present in that servlet.
Note: Data is not part of the OIDC ID Token, we just trying to capture the Post Form Data that we receive from another Application.

@AkshithReddyT To capture POST form data sent from another application to Pega, you can use the pyRequestAttachmentPage or directly access the servlet request in a custom authentication activity. In your OIDC authentication service, specify a custom activity to process the incoming request. In this activity, use the pyRequestAttachmentPage to access the raw payload or use Java code like tools.getRequestor().getServletRequest().getReader().lines().collect(Collectors.joining()) to fetch the full request body. If the data is URL-encoded, parse it using Pega utilities or Java libraries. Once extracted, map the form data to clipboard properties or a data page for use in your application. Ensure that the Service Package of the authentication service is configured to accept requests securely. Use Tracer to debug and verify the incoming request during authentication. This approach works independently of the OIDC ID token, focusing solely on capturing and processing the form data from the payload.
