Heap Webhooks API

Partner-registered webhook endpoints invoked by Heap. The onlydocumented action type is `segment.users.sync`, which deliversdelta adds/removes for a Heap behavioral segment.Signature verification: 1. Parse the `Heap-Hash` header (comma-separated key:value pairs). 2. Confirm the `ts` value is within the partner's tolerance window. 3. Concatenate `${ts}${requestbody}`. 4. Compute HMAC-SHA256 using the `webhook_secret_key` assigned at webhook creation. 5. Constant-time compare against the `hmac` value from the header.Return `200 OK` on success; `429` or other non-2xx responses triggerretries by Heap.

Where this information came from

This is an independent, third-party profile of Heap 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.
