[Platform guide](https://docs.openpo.st/providers/threads) Formats and limits ## Different formats, different rules. OpenPost checks the text and media rules for the format you choose. | Format | Text | Media | | --- | --- | --- | | Post or reply thread | 500 characters | Text only | | Image or video | 500 characters | One public HTTPS media item | | Carousel | 500 characters | 2-20 public HTTPS images or videos | ### Provider limits and scope - 500 characters - One media item or a 2-20 item carousel - Reply chains - Public media URL and approved Meta app access required Connect and test ## Set up Threads in three checks. 1. Configure the Threads app credentials and exact OAuth redirect URI. 1. Make stored media reachable through a public HTTPS URL that Meta can fetch. 1. Connect the account and test image, video, or carousel publishing from production-like hosting. Known limits ## What can still block a post. - Meta fetches media server-side; localhost, private URLs, and inaccessible object storage will fail. - Video processing and account permissions can still fail after a successful OAuth connection. - Local development needs a public tunnel for callbacks and media. **Account requirement:** An approved Meta app and public HTTPS media hosting for media posts. **Verification:** Verify that Meta can fetch the exact production media URL before scheduling media-heavy work. ## Use the current callback address, permissions, and media setup. Social network developer pages change. The OpenPost guide lists the settings and checks you need now. [Read the Threads guide](https://docs.openpo.st/providers/threads)
