Three real ways to build on CertPie

Whichever fits your stack - direct API calls, a Zapier automation, or an AI assistant that already has access.

Call the API from your own backend

Queue a batch, check its status, and look up a finished certificate - the same pipeline the dashboard's bulk-generate wizard uses, with no separate rendering path.

See the endpoint

Automate with Zapier

A published Zapier integration: a “New Batch Completed” trigger and a “Generate Certificate” action, so a batch finishing anywhere can kick off the rest of your workflow.

How triggers work

Connect via Claude

A published MCP connector - no API key to copy, no terminal. Add it in Claude's Connectors settings and it signs in with your CertPie account directly.

From API key to delivered certificate

  1. 01

    Create an API key

    Generate a key from Settings > API. It's shown in full exactly once - CertPie only ever stores its hash.

  2. 02

    Generate a batch

    POST a template ID and a list of recipients. CertPie queues it for background generation and returns a batch ID right away.

  3. 03

    Track it

    Poll the batch by ID, or subscribe to the batch.completed webhook instead and skip polling entirely.

  4. 04

    Look up a certificate

    Once generated, fetch any certificate by ID for its PDF URL, its public verification link, and its status.

Get notified, instead of polling

Subscribe to batch.completed and CertPie delivers a signed POST the moment a batch finishes - the same event that powers the Zapier "New Batch Completed" trigger. Every delivery follows the Standard Webhooks shape, so verifying one is a single HMAC-SHA256 check.
