You can create up to 40 API keys and also update and delete them, allowing for _credential rotation_.\n\nThe _Agent Activation_ process will generate an initial API Key for you. See [Activate Agent](#section/Getting-Started).\n\nA call to the [createApiKey](#operation/createApiKey) endpoint will return the following structure:\n\n```json\n{\n \"key\": \"apk-1wtRxni5IsPsSpBLWpwr\",\n \"status\": \"active\",\n \"agentKey\": \"cgt-1wtRvFLIjDOyyUR5Q2LB\",\n \"description\": \"Data lake API key\",\n \"permissions\": [\n \"charges:List\",\n \"reports:All\"\n ],\n \"created\": \"2021-06-22T11:21:45.115Z\",\n \"secret\": \"FWtnOOHAjbD6rNxWWEeVOCj7JXSEPGJQ\",\n \"version\": 1\n}\n```\n\n> **Important:** The `secret` is only returned once in the response to the `createApiKey` call.\n\nOnce created, the `key` and `secret` fields from the API key must be used in the HTTP `Authorization` header using the `Basic` scheme.\nThe Basic scheme requires a **username** and **password** to be specified, separated by a `:` (colon) and Base64 encoded.\n\nUse the following values from the API key to construct a Basic authentication header:\n\n| Basic field | API key field | Example |\n| ----------- | ------------- | ------- |\n| username | `key` | `apk-1wtRxni5IsPsSpBLWpwr` |\n| password | `secret` | `FWtnOOHAjbD6rNxWWEeVOCj7JXSEPGJQ` |\n\nIn pseudo-code a valid HTTP Basic Authentication header would be constructed as follows:\n\n```ts\nconst apiKeyId = \"apk-1wtRxni5IsPsSpBLWpwr\";\nconst apiKeySecret = \"FWtnOOHAjbD6rNxWWEeVOCj7JXSEPGJQ\";\nconst authnValue = \"Basic \" + base64Encode(apiKeyId + \":\" + apiKeySecret);\nrequest.setHeader(\"Authorization\", authnValue);\n```\n\nUsing the values from the example a valid HTTP request would look like the following:\n\n```http\nGET /v1/agents/current HTTP/1.1\nAccept: application/json\nAuthorization: Basic YXBrLTF3dFJ4bmk1SXNQc1NwQkxXcHdyOkZXdG5PT0hBamJENnJOeFdXRWVWT0NqN0pYU0VQR0pR\n```\n\nMore information on the Basic scheme can be found in [RFC-7617 - The 'Basic' HTTP Authentication Scheme](https://datatracker.ietf.org/doc/html/rfc7617)." type: http scheme: basic BearerToken: description: 'Bearer tokens are temporary security credentials that can be used to authorize ''third parties'' (bearers) access to the Silverflow API on behalf of the agent. These tokens are created by calling the [createAgentBearerToken](#operation/createAgentBearerToken) endpoint. Once created the `token` field must be used in the HTTP `Authorization` header using the `Bearer` scheme. Here''s an example of an HTTP request with a bearer token: ```http GET /v1/merchants/mct-1hPdFhmgaBzMS191nIbJ HTTP/1.1 Accept: application/json Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...40EFOgxf_3I6mPZ16bXqHd5tUyApgl0mNOAXPm5AhnA ``` More information on the Bearer scheme can be found in [RFC-6750 - The OAuth 2.0 Authorization Framework: Bearer Token Usage](https://datatracker.ietf.org/doc/html/rfc6750).' type: http scheme: bearer bearerFormat: JWT MutualTLS: type: apiKey in: header name: '-' description: 'The client must set up mTLS connection with a valid X.509 client certificate signed by a customer-provided CA (certificate authority) that is registered to a specific agent. The customer-provided CA certificate must be shared and added to Silverflow''s trust store prior to calling endpoints. Certificate validation happens at the transport layer during TLS handshake. Tenant verification is performed by matching the agent key embedded in the client certificate against the agent key embedded in the trusted CA.
