I've set up Twitter OAuth 2.0 authentication with read and write permissions, but I'm receiving 403 Forbidden errors when trying to create tweets or access user information. What works:

Successfully redirecting users to Receiving authorization code after user grants permission Successfully exchanging code for access token via Receiving token response with correct scopes:

json: { "token_type": "bearer", "expires_in": 7200, "access_token": "[REDACTED]", "scope": "tweet.write tweet.read" } What fails:

Creating tweets with returns:

json: { "title": "Forbidden", "type": "about:blank", "status": 403, "detail": "Forbidden" }

Getting user info with returns the same 403 error

Implementation details:

Using React.js for frontend Twitter Developer Account has read and write permissions enabled Using OAuth 2.0 authorization code flow Including appropriate headers:

Authorization: Bearer [access_token] Content-Type: application/json

Request body for tweet creation:

jsonCopy{ "text": "Test tweet" } What I've tried:

Verifying app permissions in Twitter Developer Portal Confirming the OAuth scopes include tweet.read and tweet.write Testing with Postman using the same access token Checking Twitter API documentation for required permissions

Questions:

Why am I getting 403 Forbidden errors despite having a valid access token with appropriate scopes? Are there additional permissions or settings required for these endpoints? Could this be related to my Twitter Developer Account access level (Essential vs Elevated)? Are there any common gotchas with the Twitter API v2 that I might be missing?

Any help would be greatly appreciated
