Web API Common Features

Some aspects of the Web APIClosed A set of functions to allow creation of applications. Keyfactor offers the Keyfactor API, which allows third-party software to integrate with the advanced certificate enrollment and management features of Keyfactor Command. request and response formats are consistent across all endpoints. This includes a small set of HTTP headers, HTTP statuses returned by the server for successful requests, and various error conditions. Common request headers are given in Table 65: Common Request Headers, common response headers (for successful requests and certain unsuccessful requests) are given in Table 66: Common Response Headers, and HTTP statuses are given in Table 67: HTTP Statuses.

Additionally, many Classic APIClosed A set of functions to allow creation of applications. Keyfactor offers the Keyfactor API, which allows third-party software to integrate with the advanced certificate enrollment and management features of Keyfactor Command. methods operate on a certificate resource stored in Keyfactor Command, and a standardized way to identify the certificate for the operation is used in the request structure across several Classic API components; this is described in Table 68: Classic API Certificate Lookup Structure. This table does not apply to the Keyfactor API.
