The PostBoost REST API lets you publish, schedule, and analyze social media posts on every supported network from a single integration. No OAuth apps to maintain — PostBoost handles platform authorization for you. ## Base URL All workspace-scoped endpoints are prefixed with `/{workspaceUuid}`. Panel/admin endpoints are prefixed with `/panel`. ## Plan access Every workspace-scoped endpoint returns `403` when the workspace's plan does not include API access (capability `api`). ## Dates and times Post dates and times (`date`, `time`, `accounts_schedule`) are read in the request's `timezone` when one is given, otherwise in the workspace timezone. ## Idempotent requests Send an `Idempotency-Key` header (any unique string, for example a UUID) with a `POST`. Repeating the request with the same key within 24 hours returns the stored response with `Idempotent-Replayed: true` and creates nothing new. Reusing a key with a different body returns `422`; a request still in progress with the same key returns `409`. `5xx` and `429` responses are not stored, so they can be retried with the same key. ## Guardrails for automated clients Create and update requests are checked before anything is written: a post whose content matches one created for the same account in the last 24 hours returns `409` (`code: duplicate_post`, override with `allow_duplicate: true`), scheduling past an account's daily cap returns `429` (`code: account_daily_cap_reached`), and scheduling to an account that must be reconnected returns `422` (`code: account_unauthorized` or `account_token_missing`). Use `POST /{workspaceUuid}/posts/validate` for a dry run and `GET /{workspaceUuid}/activity` to review what API clients did. ## Authentication All requests require a Bearer token in the `Authorization` header. Generate tokens in your PostBoost dashboard under **Settings → Access Tokens**. ``` Authorization: Bearer YOUR_API_TOKEN ```
