Frequently asked questions
How many networks can I use in one request?
All the ones you have connected. Each one is published independently.
What if one network fails?
The rest are published anyway. We retry the failed one and send you the reason by webhook if it cannot go out.
Can I edit or delete a post?
Yes, on the networks that allow it, with the same API.
