How do I update a customer’s email address?

When a customer logs in to your platform, their email address is passed as a value in the Intercom Messenger’s code (a parameter called email:).

You’ll need to make sure that you’re passing the customer’s new email address as the value here.

While you can update a customer’s email address through our API, this value will be overwritten on the customer’s next login if you haven’t made the necessary changes to the Messenger code outlined above.
