POST
/v1/postsTL;DR
| Question | Answer |
|---|---|
| What does it do? | Schedule a post. |
| What does it need? | An API key or an OAuth access token. |
| What does it take? | A JSON body with the fields below, and idempotency-key in a header. |
| What does it return? | Status 201 with a body of type Post. |
| In the SDK? | flung.posts.create() |
| As an MCP tool? | schedule_post |
| What can go wrong? | 401 Missing, unknown, revoked or expired API key; 422 The request failed validation; 429 Too many requests for this credential; wait for retry-after seconds. Every failure has the same error shape. |
What it does
Schedules one post to one or more connected accounts. Send an Idempotency-Key header so a retry never posts twice.
