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.

Where this information came from

This is an independent, third-party profile of EasyPost Webhooks API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
