/v2/customers

Creates a new customer that can be set up with payment method sources and can make payments. Each customer should represent a unique individual or corporate body.

If a customer is resetting a payment method, edit the payment method on the existing customer. Duplicate customer entities may lead to failed payment initiation and incorrect fraud flagging.

The mobile and email for the customer must be unique across your Stronghold Pay account. At least one of mobile or email is required.

The country should be set retail or delivery location for the customer’s orders, being the merchant’s country in the case of goods pickup or where services are being provided. state must be provided if the country is US; otherwise, it may be omitted. For a list of valid countries, states, and territories, see Countries.

You can link a Stronghold Pay customer entity to your internal customer users in two ways:

1. track the customer.id returned from the API; or,
2. send your own customer ID as the external_id when creating a customer.
