| 1 | //! The webhooks service: events, delivered to the addresses a repository or |
| 2 | //! a workspace registers. |
| 3 | //! |
| 4 | //! Every event g1t publishes can be delivered: an HTTPS `POST` of JSON, |
| 5 | //! signed with the webhook's secret in `X-G1t-Signature-256`, and retried |
| 6 | //! with growing waits when the receiver does not answer with a 2xx. Each |
| 7 | //! delivery is kept, with what was sent and what came back, and can be sent |
| 8 | //! again. |
| 9 | //! |
| 10 | //! Mirrors `packages/contracts/src/webhooks.ts`. |
