Authentication & Security 2

SEDNA Message API declares 2 security schemes for authenticating requests. It accepts HTTP basic authentication (Basic). It supports OAuth 2.0 (OAuth) using the clientCredentials flow, exposing 53 scopes. By default, every request must be authenticated.

  • Basic — The basic auth scheme only requires the API-Specific username/password to be set.
  • OAuth — This API prefers OAuth 2 with client credentials flow. You can create your credentials in the Api Credential Management page .

Where this information came from

This is an independent, third-party profile of SEDNA Message 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.
