FREQUENTLY ASKED QUESTIONS
Before your first post.
Do I need to know how to code?
Not to use the dashboard: connect your account, upload images, then publish or schedule. The API lets you add the same workflow to your product or automation.
Does one Postmatic account replace my social accounts?
No. Your Postmatic account centralizes the workflow. You still need an account on each network and must authorize each connection. You can currently connect an Instagram professional or creator account approved for access.
Which channels and formats can I use today?
Instagram images and carousels. Other channels are marked as planned. Videos, Reels and Stories are not available yet.
What happens if a post fails?
Check the status and error in the dashboard or API. Eligible temporary failures are retried automatically. Authorization or content issues may require reconnecting the account or correcting the post.
Can I access analytics yet?
Not yet. Today you can track post delivery. Content performance metrics are on the roadmap, with no release date announced.
What does it cost and who can join?
Access is free during this initial phase, with no credit card required. Your Instagram professional or creator account must be approved for connection; creating a Postmatic account does not automatically grant access on Meta. Future commercial terms have not been defined yet.
