The Clinch SDK requires you to provide the user's current balance for display within the Clinch web app. You can do this by using the getBalance callback function, which should return the user's balance and currency when requested by the iframe.
NOTE: User's balance will only be used locally, we will not send this value to our server.
Implementing the getBalance Callback
The getBalance function should retrieve the user's balance from your system and return it to the Clinch web app.
Here’s an example which returns $1.00:
functionasyncgetBalance(){return{balance:100,currency:"cents",// Your currency};}
