Merge Customers

I have a 3rd party form builder that creates customers and saves cards on those customers but they aren’t able to check to see if a customer exists before creating them so we’re going to have duplicate customers, is there any way to merge customers through the Customers API?

Hello Michael - Thanks for the post! I’m a PM working on the Customers API here at Square. We currently don’t have a mechanism to merge customers through the Customers API, but we’ll keep this in mind when we consider future improvements.

Thanks @immanuel! That would be really helpful.

Hi @mjshinner,

From our testing, it appears that Square has started auto-merging some customers when the same card is used. This may cut down on your number of duplicate customers.
