Hi,
I'm trying to follow the guide for implementing OAuth for Apple Search Ads Api: https://developer.apple.com/documentation/apple_search_ads/implementing_oauth_for_the_apple_search_ads_api
I've created both keys, uploaded the public one, generated the JWT. Something goes wrong when I try to request the access token. Everything sent with Curl, Insomnia or Postman generates a 400 response with invalid_client as data. I've used a JWT debugger to make sure that the client secret I have sent is correct. The request is sent as a POST, with the header and params set like in the example from the documentation. What could possibly be wrong? There is nothing in the documentation regarding invalid_client.
Best regards Mike
