Webhooks
Signed deliveries when something changes
Webhooks are planned for after the first version of the API, and are not available yet.
What is planned
Hatcel will send a signed HTTP request to an address you choose when something changes, so you do not have to poll. Deliveries will follow the Standard Webhooks specification, so an existing library can verify them.
Until then, poll with updated_since. See Pagination and sync.
