API to list Webhook recent deliveries?

There is a developer guide “Testing Webhooks” at https://developer.github.com/webhooks/testing/. Are there corresponding APIs to list Webhook recent deliveries and show details of individual one? 


To my knowledge, there isn’t an API to list webhook deliveries. You can use the Events API to list events for a repo, org or user though and find the payload you’re looking for that way:


Depending on how recent the event is and how busy the target is, you may be sifting through a lot of data that way though. You would have to watch out for rate limits.

I did try the events API but could not find the info I wanted. For example, in Settings->Integration and Service, if I click the “Test service” to trigger Travis CI, I could not find such event and its request/response info through events API listed on https://developer.github.com/v3/activity/events.

When I request:


I receive:

    "message": "If you would like to help us test the Webhook deliveries API during its preview period, you must specify a custom media type in the 'Accept' header. Please see the docs for full details.",
    "documentation_url": "https://developer.github.com/enterprise/2.20/v3"

I do not find the right Accept header, have you any idea?

I tried this as well for our github app that handles check_run events and couldn’t find such events either.
I could see PR events like “opened” and “closed” in the list produced by the repository events endpoint but not check runs.

Also note this: https://developer.github.com/v3/activity/events/#events

Events support pagination, however the per_page option is unsupported. The fixed page size is 30 items. Fetching up to ten pages is supported, for a total of 300 events.

So the list is pretty limited anyway.
