Authentication & Quotas

Authentication​

Required Headers​

Every API request must include two headers:

authorization: ApiKey YOUR_API_KEY
x-printago-storeid: YOUR_STORE_ID
  • authorization — your API key, prefixed with ApiKey .
  • x-printago-storeid — the ID of the organization (store) you are accessing. You can find this on the API Keys page.

Requests missing either header will receive a 401 Unauthorized response.

How Permissions Apply​

An API key's effective permissions are the union of its directly assigned permissions and any permissions inherited from assigned roles. If a key attempts an action it does not have permission for, the request returns 403 Forbidden.

Full Access keys behave as Store Owner and can perform any action.

Rate Limits​

API access is rate-limited across two sliding windows:

WindowLimit
Per minute60 requests
Per hour600 requests

When you exceed a limit, requests return HTTP 429 Too Many Requests until the window resets. The response includes a Retry-After header indicating how long to wait.

tip

If these limits are too restrictive for your use case, contact us to discuss higher quotas.

Real-time Data with MQTT​

For real-time printer updates, Printago provides MQTT access. This is the same data stream that powers the Printago web dashboard — giving you immediate access to printer states, temperatures, progress, and more.
