ylnh1 (ylnh1) asked a question.
I was experimenting the Token Exchange Flow (https://developer.okta.com/docs/guides/set-up-token-exchange/-/main/) . I have enabled this feature: OAuth 2.0 On-Behalf-Of Token Exchange feature
However, I was not able to go through the steps listed by this document
Issue *1 "Authorization Code with PKCE request": This document says sent /v1/authorize request via POST, I never get it work using curl or post man. After searching around, I think this document is missing a step on login. Even I add login step, and I got the sessionToken, still I cannot get this step work in either Post request as documented, or change to GET request as many browser based application does.
Because of this issue, I leverage a simple sample App (GitHub - okta/samples-js-react: React Auth SDK sample) to get the Subject Access Token. This App can let me get what we need in step: Authorization Code with PKCE request and Exchange code for tokens request
So, when I try the step: Token exchange request from service app to API, I got the error :
{"error":"access_denied","error_description":"Policy evaluation failed for this request, please check the policy configurations."}
The System Log says:

@ylnh1 (ylnh1) what's your full authorize url? the endpoint can find from :
https://xxx.okta.com/.well-known/openid-configuration
Does your tenant with API Access Management? can you find authorization server tab in the API?
Thanks. I was using my developer Okta tenant, and I only configured default API server.
I followed the document steps ( (https://developer.okta.com/docs/guides/set-up-token-exchange/-/main/) and configured a NativeApp, and App1. The App1 got the access_token from NativeApp, and trying to exchange another access token with different scopes. But failed with above mentioned error.
I did configured the access policy per steps mentioned by the document. So, I think it is a different issue mentioned by @Paul S. (Okta, Inc.)
This is my API server
Access AP1 policy Rules:
Access API2 policy
