Keys APIs

Overview

This API has been available since 1.6.0

Cryptographic keys are used in signing and verifying JWTs and verifying responses for third party identity providers. It is more likely you will interact with keys using the FusionAuth UI in the Key Master menu. If you do have a need to retrieve or manage keys using the API the following APIs have been provided.

Retrieve a Key

This API is used to retrieve a single Key by unique Id or all of the configured Keys.

Request

Retrieve all of the Keys

URI

GET /api/key

Retrieve a Key by Id

URI

GET /api/key/{keyId}

Request Parameters

keyId [UUID] Required

The unique Id of the Key to retrieve.

Response

The response for this API contains either a single Key or all of the Keys. When you call this API with an Id the response will contain a single Key. When you call this API without an Id the response will contain all of the Keys. Both response types are defined below along with an example JSON response.
