For developers

SponsorPass is a separate service that talks to a Ghost site through its Admin API with the key of a custom integration, and listens to the site's webhooks. These pages describe every surface a developer meets:

• the snippet a publisher pastes into code injection, and what it sends where;
• the theme hook for placing the button yourself;
• the webhooks the service registers and how it verifies and recovers;
• the Ghost versions it supports and the packages it pins;
• the HTTP API the dashboards use;
• the changelog.

The source of truth for every Ghost claim here is the pinned Ghost source the service is developed against; the knowledge base in the repository cites it file by file.
