Authentication & Security 3

ZenZap Messages API declares 3 security schemes for authenticating requests. It accepts HTTP bearer tokens (bearerAuth). An API key is passed in the header as X-Signature (hmacSignature). It supports OAuth 2.0 (oauth2ClientCredentials) using the clientCredentials flow, exposing 12 scopes. By default, every request must be authenticated.

  • bearerAuth — Bearer token for the request. Two flavors: - Static API key — pass your API key (the value returned as apiKey when the bot was created). Must be paired with X-…
  • hmacSignature — HMAC-SHA256 signature for request verification. Required only when authenticating with a static API key. Omit when using an OAuth access token.
  • oauth2ClientCredentials — OAuth 2.0 clientcredentials grant for API-key bots. Use the clientId and clientSecret returned when the bot was created (or rotated) to mint short-lived access…

Where this information came from

This is an independent, third-party profile of ZenZap Messages 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.
