Developer Account



I have to create/upload tailored audiences through API.
I have created app and generated access tokens, used details for accessing - and api’s but receiving 403 error - (code - UNAUTHORIZED_CLIENT_APPLICATION & message:The client application making this request does not have access to this API.

After that I applied for developer access for my app, I just got email from twitter with details of twitter ads api contract. API access is not working.

Can someone help me what might be the issue?

Will twitter review my application for developer access and grant access? do I need to wait for confirmation?
