Authentication & Security 5

Clerk Well Known API declares 5 security schemes for authenticating requests. An API key is passed in the cookie as __client (ProductionBrowser). An API key is passed in the query as __dev_session (DevBrowser). It accepts HTTP bearer tokens (ProductionNativeApp). An API key is passed in the query as _is_native (ProductionNativeFlag). It accepts HTTP basic authentication (ClientCredentials). By default, every request must be authenticated, though some operations may also be called without credentials.

  • ProductionBrowser — The Client API token sent in the form of a browser cookie. Used to authenticate production browser applications.
  • DevBrowser — A Dev Browser API token sent as a query parameter. Used to authenticate only dev instances. To generate a dev instance API token you must first make a request…
  • ProductionNativeApp — The Client API token sent in the Authorization header. Used to authenticate native applications.
  • ProductionNativeFlag — If sent and the value is true, it instructs the server to parse the API token from the Authorization header. It should always be set to true when using the Aut…
  • ClientCredentials — HTTP Basic Authentication using Client ID as username and Client Secret as password.

Where this information came from

This is an independent, third-party profile of Clerk Well Known 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.
