Authentication

The Postzee public API uses API key authentication. All endpoints require a valid API key sent in the Authorization header.

Base URL

https://api.postzee.app/public/v1

Include your API key in the Authorization header of every request:

curl -H "Authorization: YOUR_API_KEY" \
  https://api.postzee.app/public/v1/credits

Do not use the Bearer prefix. Send the API key directly as the header value.

A paid plan (Standard or higher) — the Free plan does not include API access
An active subscription — expired subscriptions cannot use the API
Account must not be blocked

All error responses follow this format:

{
  "statusCode": 401,
  "message": "Unauthorized"
}

Use the health check endpoint to verify your API key works:

curl -H "Authorization: YOUR_API_KEY" \
  https://api.postzee.app/public/v1/is-connected

Success response:

{
  "connected": true
}
