Removes a callback function that was added through addListener()


First, initialize chat fully

Kustomer Chat must finish initializing fully with Kustomer.start() before you can execute any additional Web SDK methods.

Tip: Call other methods inside the callback of Kustomer.start() to ensure Kustomer Chat always completes initialization before the code tries to run other methods.

To learn more, see Troubleshooting: Kustomer method calls won't execute.


We're provided some examples of how you can call Kustomer.removeListener():

const onOpenHandler = function () {
  console.log('Widget was opened');

Kustomer.addListener('onOpen', onOpenHandler);

Kustomer.removeListener('onOpen', onOpenHandler);


Kustomer.removeListener(event, function)


Is that really you?

When you use removeListener, make sure that the function you pass in is the same reference as the one you used when you ran addListener or it won't be removed properly.
