Trying to use “…/2/tweets/search/all” for an Elevated App results in:
“detail”: “When authenticating requests to the Twitter API v2 endpoints, you must use keys and tokens from a Twitter developer App that is attached to a Project. You can create a project via the developer portal.”,
“title”: “Client Forbidden”,
“required_enrollment”: “Standard Basic”,
“reason”: “client-not-enrolled”,
I’ve tried it both by adding the env variable in Postman or directly with curl and just explicitly pasting the bearer token there.
Other endpoints work because they allow for different auth but I can’t seem to hit this one.
I’m sure it’s just something I’m missing but I just can’t see it 
Thanks for your help with this!
You need special Academic Access for the search/all endpoint Twitter Developer Access - twarc
