By using elepay’s Customer feature, you can create customers to support recurring billing or to charge using registered payment methods. The Customer feature uses both the Client SDK and the API.

Customer creation flow overview

Create a customer via API

1. Register a payment method

The end user registers a payment method in a mobile app or on the web.

2. Create the customer

Your server calls Create Customer to create a customer linked to the user. If you need to register multiple payment methods, reuse the existing customer.

3. Create a Source object

Your server calls Create Source to create a Source object.

4. Pass the Source object

Your server returns the Source object from elepay to the Client SDK on the client.

5. Registration (authorization)

The Client SDK runs the registration process using the Source object.

6. Registration (authorization) result

After registration completes, the selected payment channel server returns the result.

7. Receive webhook event

If registration succeeds, elepay sends a source.activated event notification to the configured webhook URL.

8. Charge recurrently

Using CustomerId and SourceId, your server calls Create Charge to process payments.
