Webhook Content Publishing for Headless Sites
A reliable publish pipeline needs a versioned contract, receiver-side validation, and a clean separation between ingest and publish. Here is the architecture and where each part tends to break.

Version your payload contract before you need to
The moment you add a field to your webhook payload — a new metadata field, a schema type, an author object — every downstream consumer that assumed the old shape can break silently. Version the contract from the first integration, even if you're the only consumer today.
Validate at the receiver, not just at the source
Run schema validation on the incoming payload before writing anything to your database. Reject malformed payloads with a specific error response rather than silently dropping fields — a partial record that looks complete is far harder to debug three weeks later than a clean 400 response today. PrismSEO's publishing reference documents the exact payload shape, required versus optional fields, for teams building a custom receiver.
Separate ingest from publish
Store the incoming payload first, then process and publish asynchronously. This one architectural choice prevents the most common failure mode in webhook publishing: an upstream retry after a timeout causing the same article to publish twice because the first attempt's response never made it back.
Start here if you're building your first receiver
The webhook quickstart guide has a minimal working receiver, and the webhook integration page covers exactly what PrismSEO sends on each publish event.
