Authentication

The REST API authenticates with an API key. Create a key in your Posteady settings and send it as a Bearer token on every request:

Authorization: Bearer pk_your_key_here

Keep the key secret — it grants access to your connected accounts. Treat it like a password: store it in an environment variable, never in client-side code.

The REST API requires the Creator plan or above. See Plan & Rate Limits for quotas.
