Authentication

Authenticated endpoints require a Bearer token from Routee.

Prerequisites: Create a Routee application

Before using the Failover OTP service, you must create a new application in the Routee portal and use that application for all API calls.

Requirement	Details
Where	Routee Applications (`https://go.routee.net/management/applications`)
Token expiration	Set Token Expiration to Unlimited. This is required for the service to work correctly.
Usage	Use this application’s credentials (Application ID and Application Secret) for authentication.

If token expiration is not set to Unlimited, the service may not work as expected.

Create new application with Token Expiration Settings: Unlimited

Obtaining and using a Bearer token

Obtain your Application ID and Application Secret from your application in the Routee Applications page.

Request an access token:

POST https://auth.routee.net/oauth/token
Authorization: Basic <base64(applicationId:applicationSecret)>
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials

Use the returned access_token in all authenticated requests:
```
Authorization: Bearer <access_token>
```

With Token Expiration set to Unlimited, your tokens do not expire. On 401 or 403 (e.g. revoked credentials or invalid token), obtain a new token and retry.
