Notes

Of the Vercel webhook events, this PR has support for all the project and deployment (except deployment.ready) events.

The remaining events are configured at an Integration level (what Vercel provides as OAuth) and hence cannot be configured with the create-webhook API for each request separately. These events need to be configured when the Integration is created on the Vercel platform, so there can be only one Webhook URL set at the top level for these events. This also means OAuth cannot be configured per each user on the trigger.dev server.

To verify the Vercel Integration workflow, I created a test Integration (trigger-dev-hmacr-test). I then configured an endpoint as the Integration webhook-url which received the webhook events from the teams/projects where the Integration was installed.

If we need to support OAuth (and the Integration level webhook events), the path forward is

• Set up an endpoint to receive all the Vercel Integration level webhook events.
• Parse the payload and create event records (same as a webhook handler).
• Optionally, implement tasks that can only be performed by an OAuth client, e.g. create-check API.

I've also opened a discussion to find information about refreshing the OAuth access token: Refresh Token for Integration 💯
