OAuth 1.0a User Context Unsupported for /2/media/upload in API v2
The post content has been automatically edited by the Moderator Agent for consistency and clarity.
Want to use over 200+ MCP servers inside your coding tools like Cursor?
Migrating to API v2 is proving challenging since I can create posts with /2/tweets using an OAuth 1.0a User Context token, but uploading media attachments with /2/media/upload is blocked. This forces the use of OAuth 2.0 User Context, which means re-authorizing users—a process I’d like to avoid.
Is there any workaround to use OAuth 1.0a User Context for media uploads, or must I fully switch to OAuth 2.0 for this endpoint?
Example error message:
JSON{ "detail": "Authenticating with OAuth 1.0a User Context is forbidden for this endpoint. Supported authentication types are [OAuth 2.0 User Context].", "title": "Unsupported Authentication", "status": 403, "type": "https://api.twitter.com/2/problems/unsupported-authentication" }

Twitter API v2 Media Upload Authentication Issue
Based on the error message you're receiving, it appears that the /2/media/upload endpoint specifically requires OAuth 2.0 User Context authentication and does not support OAuth 1.0a User Context.
Unfortunately, there is no direct workaround to use OAuth 1.0a for the media upload endpoint if the API explicitly requires OAuth 2.0 User Context. This is a deliberate restriction in the Twitter API v2 design.
You have a few options:
-
Use the v1.1 media upload endpoint: If still available, you might be able to use the v1.1 media upload endpoint (
https://upload.twitter.com/1.1/media/upload.json) with your OAuth 1.0a credentials, and then reference the media ID in your v2 tweet creation. -
Implement OAuth 2.0 authentication: This would require re-authorizing your users, but it's the most future-proof solution as Twitter is clearly moving toward OAuth 2.0.
-
Create text-only tweets: If media uploads are not critical for your application, you could continue using OAuth 1.0a for text-only tweets.
The error message is quite clear that for this specific endpoint, OAuth 2.0 User Context is required, and there's no indication of any exception or alternative authentication method being supported.
