Uptime report for last month
Pick the time and timezone. Nothing goes out until its scheduled moment, and you can cancel any time before.
Upload images, videos, carousels, Stories, and Reels. One payload, every destination.
Publish, fail, comment, or DM. Every event hits your endpoint the moment it happens.
Add a first comment to the same call. It publishes alongside the post where supported.
One call returns likes, comments, and shares from every platform in the same shape.

Launch day is live. Everything shipped from one call.
Pages versus profiles, photo sizes, post formats, drafts, and posting to another Page.
No. Meta does not allow API publishing to personal profiles, so every Facebook destination is a Page you hold a role on. One Page is one connection — connect again to add another.
Facebook rejects many photos above 4 MB in practice, even though the stated ceiling is higher. Keep images under 4 MB in JPEG or PNG.
Text on its own, a single photo, multi-photo albums of 2 to 10 images, multi-link carousels, video, Reels, Page Stories, and unpublished drafts.
Multi-photo albums take images only. A video URL in the list is rejected, so send video as its own post.
Yes. Send draft: true and the post lands in the Page's Publishing Tools unpublished, ready for a person to finish.
Yes. Pass pageId on the destination to post to another Page managed by the same organization, without adding a second connection.
Yes. The OAuth screens your users see carry neutral names like Social Media Connector rather than our brand, so the experience reads as fully yours.
