EasyPost Webhooks API
Asynchronous Event delivery surface. EasyPost POSTs Event objects to subscriber URLs whenever asynchronous objects (batches, trackers, scan forms, refunds, reports, payments, claims, insurance, shipment invoices) change state. Each delivery is signed with an HMAC-SHA256 signature in the X-Hmac-Signature header, derived from a per-webhook secret. Subscribers must return a 2XX status code; non-2XX responses are retried.
EasyPost Webhooks API is one of 11 APIs that EasyPost publishes on the APIs.io network, described by an AsyncAPI event-driven specification.
Tagged areas include Webhooks, Events, AsyncAPI, and HMAC. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.
This event API exposes 1 operation across 1 channel, and defines 25 schemas. It is described by AsyncAPI 2.6.0, at version 1.0.0.
The API connects through a single server, {webhook_url} (https).
