OAuth 2.0 Error: 401 Unauthorized with X Create a Post Module

Hi Make Community,

I’m experiencing an issue with the X (formerly Twitter) integration in Make.com. While the Watch Posts module works perfectly for retrieving tweets, the Create a Post module fails with the following error:

Failed to verify connection ‘My X (formerly Twitter) OAuth 2.0 connection’. Status Code Error: 401

Here are the details of my setup:

  1. The app in the X Developer Platform has Read and Write permissions enabled.
  2. The connection was authorized successfully, as the Watch Posts module works without any issues.
  3. The Create a Post module is configured to include:
    • Text Content mapped from the OpenAI Assistant module.
    • Quote Post ID mapped from the Watch Posts module.
    • (Optional) Media Keys mapped when media is present.
  4. I’ve double-checked the Client ID, Client Secret, and Redirect URI—they’re all correct.

Steps I’ve tried:

  • Reauthorizing the connection in Make.com.
  • Testing with static text instead of dynamic mappings.
  • Reviewing the X API documentation for Create a Post.

Despite these efforts, I still encounter the 401 error specifically with the Create a Post module.

Has anyone else faced this issue? Is there something I might be missing in my configuration or permissions? Any help or guidance would be greatly appreciated!

Thanks in advance for your support!
