Hi there @tommy38hk 👋🏻 , thanks for filing the issue and sorry you're running into trouble here.

Are you able to share the CURL command structure you're using that is successfully making the API call?

The example configuration you provided looks like it's encoding the HTTP request body as application/json, whereas the Auth0 documentation for POST /oauth/token is expecting application/x-www-form-urlencoded in the request body.

Hi @austinvalle Here's the CURL command from Auth0, I have replaced the actual values of the sensitive fields.

curl --request POST \ --url https://my.auth0.com/oauth/token \ --header 'content-type: application/json' \ --data '{"client_id":"my-auth0-client-id","client_secret":"my-ayth0-client-secret","audience":"my-auth0-api-audience","grant_type":"client_credentials"}'

Quick test before I try and reproduce that issue, can you try updating your data block to use the Content-Type header, currently it only has Accept set:

data "http" "auth0_token" {
  url = var.auth0_token_endpoint
  request_body = local.auth0_json
  method = "POST"
  request_headers = {
    content-type = "application/json"
    accept = "application/json"
  }
}

Yes, that fixed the issue. Thank you so much
