Building X Poster with Image

[Infinitara]

Hi Guys, I followed a tutorial on here to create an X poster with image but when trying to upload the image to X in order to get the media ID, I am presented with a 403 error, I have tried both the v1.1 and v2 API endpoints on X.

I have followed endless tutorials and conferred with CGPT/DeepSeek to no avail - My account is under 1month old, CGPT suggested this could be the issue.

Any help would be greatly appreciated.

Hi @Infinitara

I’ve shared a detailed explanation on how to post a tweet with media. Please follow the steps outlined here and use the ready-to-go workflow examples:

Post Media to X/Twitter via API (NEW)

Hello community! I’ve created a workflow for posting tweets to X (formerly Twitter) with media attachments. I wanted to share this solution since many users have been asking about this functionality. Important API Update X is deprecating the v1.1 media upload endpoint on March 31, 2025. The new endpoint /2/media/upload requires the media.write scope, which isn’t currently included in the n8n TwitterOAuth2API credentials. Temporary Workaround Until my PR is merged to officially add this scope,…

Good Morning Mohamed,

I attempted to follow your tutorial previously and wasn’t sure where to add the +media.write - After following your thread and the issues people had with your explanation of “Just copy the URL and add it to the end…” helped me! - I now have it uploading media successfully!

Thank you SOOOOOO much!
