Salesforce CDP Ingestion API: 401 Invalid JWT Token Format Error

Question

I'm trying to implement the OAuth 2.0 JWT Bearer flow for CDP Ingestion API Connected App. Below are the steps and here's the help doc reference - https://help.salesforce.com/s/articleView?language=en_US&id=sf.remoteaccess_oauth_jwt_flow.htm&type=5

1. Created a x509 cert and uploaded it on the app

2. To generate a valid JWT Token, using jwt.io, passing the correct values as header, claims set and public key + private RSA Key of the x509 cert. The Signature is Verified.

3. Next, I am using this token in the assertion header along with grant_type to generate an access_token, as mentioned in the 'Request Access Token' section of the Help Doc.

4. This returns an access_token on Postman

5. However, when I try to use this access_token to create a Bulk API Job in CDP (Ref: https://developer.salesforce.com/docs/atlas.en-us.234.0.c360a_api.meta/c360a_api/c360a_api_create_a_job.htm), it gives a 401 error saying JWT token is invalid.

Am I generating the token incorrectly? Or is the usage incorrect? Support was of no help in this case.

Answer 1

Figured it out. Looks like we need to exchange the access_token for a Salesforce CDP Token. The CDP token in the response works!
