Webhooks

About this directory

  • lib/webhooks/index.js is human-editable.
  • lib/rest/static/**/*.payload.json are manually edited and copied. When a new GHES release is created, the static webhook files from the previous version's directory are copied to a new version directory.

Editable files

  • lib/webhooks/index.js consumes the static JSON files in lib/webhooks/static and exports the data used by the REST middleware contextualizer.

Static files

Generated by script/rest/update-files.js:

  • lib/rest/static/dereferenced - dereferenced OpenAPI schema file for each version of GitHub
  • lib/rest/static/decorated - files generated from the dereferenced OpenAPI schema with the Markdown descriptions rendered in HTML

Rendering docs

When the server starts, middleware/contextualizers/webhooks.js accesses the data exported from the static webhook JSON files, fetches the data for the current version and requested path, and adds it to the context object. The added property is:

  • req.context.webhookPayloadsForCurrentVersion - all webhook payloads with a version matching the current version

Markdown files in content/developers/webhooks-and-events/webhooks/webhook-events-and-payloads.md use Liquid to display the webhook payloads in req.context.webhookPayloadsForCurrentVersion. For example {{ webhookPayloadsForCurrentVersion.user.created }} references the payload file user.created.payload.json for the version being viewed.

Note Payload files either contain the webhook action type or no action type at all. For example, user.created.payload.json is the webhook user with the action type of created. Not all webhooks have action types. If a file exists with no action type (e.g., user.payload.json) and the action types (e.g., user.created.payload.json and user.deleted.payload.json), the entry in the context for the file with no action type will be default. For example, for the three static file mentioned, the object would be:

{
  user: {
    default: "STRING VALUE",
    created: "STRING VALUE",
    deleted: "STRING VALUE"
  }
}

If no action types exist, and only user.payload.json exists, the object would be:

{
  user: "STRING VALUE"
}
