Authentication & Security 6

Netcracker Contracts API declares 6 security schemes for authenticating requests. It accepts HTTP bearer tokens (JWT) (BearerAuth). An API key is passed in the cookie as apihub-access-token (CookieAuth). An API key is passed in the header as api-key (api-key). It accepts HTTP basic authentication (BasicAuth). An API key is passed in the header as X-Personal-Access-Token (PersonalAccessToken). An API key is passed in the cookie as apihub-refresh-token (RefreshTokenAuth). By default, every request must be authenticated.

  • BearerAuth — Bearer token authentication (JWT). Default security scheme for API usage. Provide Authorization: Bearer .
  • CookieAuth — Authentication via the apihub-access-token cookie.
  • api-key — API key authentication. Send the key in the api-key header.
  • BasicAuth — Login/password authentication.
  • PersonalAccessToken — Personal access token authentication. Send the token in the X-Personal-Access-Token header; use for user-issued/script access.
  • RefreshTokenAuth — Authentication via refresh token cookie

Paths & Operations 10

Where this information came from

This is an independent, third-party profile of Netcracker Contracts 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.
