Get token

Creating an authentication token for your user

Generating an Authentication Token

To allow your users to authenticate with our web app through the Clinch SDK, you need to generate an authentication token. This token should be created when the user initiates an action to open the Clinch web app via your iframe (e.g., a button click).

Steps to Generate the Authentication Token:

1. Server-Side Service: The authentication token must be generated server-side to securely handle the API key that we provide. Do not expose the API key on the client-side to avoid security risks.

2. Calling the Authentication Endpoint: Your server should make a POST request to the following endpoint, including the user's metadata:

   POST https://api.clinch.gg/v0/wager/operator/create-token

   Request Body:

   {
     "userId": "<userId>",
     "displayName": "<userName>",
   }

   • userId: The unique ID of your user.

   • displayName: The display name of the user.

   Request Header:

   x-operator-id: your_operator_id
   x-api-key: your_api_key

3. Response: Upon successful authentication, the endpoint will return a token in the response:

   Response Example:

   {
     "status": 200,
     "data": {
       "token": "eyJhbGciOiJSUzI1NiIsInR5cC..."
     }
   }

4. Using the Token in the getToken Callback: Once you receive the token in the server response, return this token in the getToken callback of the Clinch SDK. Here's an example:

   function async getToken() {
     const response = await fetch('https://your-server.com/generate-token', {
       method: 'POST',
       headers: {
         'Content-Type': 'application/json',
       },
       body: JSON.stringify({
         userId: "user123",
         displayName: "John Doe",
         lightningAddress: "[email protected]"
       })
     });
     const data = await response.json();
     return data.token;
   }
