    OAuth2:
      description: "Authentication to the Yokoy API relies on the standard OAuth2 client credentials flow.\n\n**1. Obtain an access token**\n\nPerform a `POST` request to\n`https://accounts.yokoy.ai/oauth2/token`. Pass the client ID\nand client secret as username and password in a basic auth\nheader. Set the content-type to\n`application/x-www-form-urlencoded` and specify\n`grant_type=client_credentials` in the body.\n\n> Note: For the Yokoy test environment, use `https://accounts.test.yokoy.ai/oauth2/token` instead.\n\nExample request for the client ID `ClientId` and client\nsecret `ClientSecret`:\n```\nPOST https://accounts.yokoy.ai/oauth2/token\nAuthorization: Basic Q2xpZW50SWQ6Q2xpZW50U2VjcmV0\nContent-Type: application/x-www-form-urlencoded\ngrant_type=client_credentials\n```\nIn this example, the string `Q2xpZW50SWQ6Q2xpZW50U2VjcmV0` is\nobtained by base64-encoding the string\n`ClientId:ClientSecret`, as required for basic access authentication.\n\n> Note: Yokoy does not require or use scopes.\n\n\nThe JSON response contains the access token in the attribute\n`access_token`. The response also contains the expiration in\nseconds.\n\nExample response:\n```\n{\n    \"access_token\": \"SOME_KEY\",\n    \"expires_in\": 3900,\n    \"token_type\": \"Bearer\"\n}\n```\n\n**2. Pass the bearer token**\n\nPass the access token from step 1 as a bearer token in subsequent requests to the API.\n\nExample header field for the example response from step 1:\n```\nAuthorization: Bearer 4lDvPkrBF87WHuyvlINQD\n```\n\nFor more information, see (Authentication & authorization)[https://developer.yokoy.ai/docs/overview/authentication].\n"
