[X] Create post
The [X] Create Post block publishes a post to an X (Twitter) account directly from a MindStudio workflow.
Post text and media to X from a workflow
The [X] Create Post block publishes a post to an X (Twitter) account directly from a MindStudio workflow. It takes a text string of up to 280 characters as its primary input, along with an OAuth connection ID that identifies which X account to post from. Optionally, you can attach up to four media items — images, GIFs, or videos — by providing their publicly accessible URLs in the mediaUrls array.
The block's output is void, meaning it performs the posting action without returning data to the workflow. This makes it a terminal or side-effect step rather than a data-producing one. The text and media inputs can be populated dynamically using variables from earlier steps in the workflow, allowing the post content to be generated or assembled upstream before being published.
This block fits into workflows that involve automated social publishing, such as posting AI-generated content on a schedule, sharing summaries of processed data, or triggering announcements based on external events. It is typically placed near the end of a workflow after content has been prepared by other blocks.

Yes. You can provide up to four media items via the mediaUrls array. Each URL must be publicly accessible. Supported formats include JPEG, PNG, GIF, WEBP, and MP4.
