The Modem Pay API’s customer management is built to help you store and manage customer details efficiently. Below are detailed steps and example requests for creating, retrieving, updating, deleting, and listing customers, as well as listing their payment methods. This allows you to manage customer profiles and payment preferences seamlessly.

​
Create a Customer

To create a customer, use the modempay.customers.create() method, which allows you to add key information like the customer’s name, email, phone number, and an optional starting balance. The distinct option, when set to true, checks for existing customers with matching fields (e.g., email) to avoid duplicate entries. If distinct is omitted or set to false, a new customer entry will be created without duplicate checks. Sample Request: 
const customer = await modempay.customers.create(
    { name: "Zypheron Kade", email: "zypheron.kade42@protonmail.com", phone: "7000001" },
    { distinct: true }
);
Sample Response: 
{
  "id": "8a8c8a0e-c5d2-4692-a94b-25284d36adc7",
  "balance": 0,
  "name": "Zypheron Kade",
  "email": "zypheron.kade42@protonmail.com",
  "phone": "7000001",
  "business_id": "a10a51ae-05c8-406e-968c-7b1d309a77e0",

  "createdAt": "2024-11-11T13:54:10.104Z"
}

​
Retrieve a Customer

To fetch a customer’s details, use modempay.customers.retrieve(customerId). Replace customerId with the customer’s unique ID. Sample Request: 
const customer = await modempay.customers.retrieve(
  "8a8c8a0e-c5d2-4692-a94b-25284d36adc7"
);

    { name: "Chibuike Okpara" }
);
Sample Response:

  "id": "8a8c8a0e-c5d2-4692-a94b-25284d36adc7",
  "name": "Chibuike Okpara",

await modempay.customers.delete("8a8c8a0e-c5d2-4692-a94b-25284d36adc7");

​
List All Customers

To view all customers, use modempay.customers.list(). This returns a list of customers, with pagination options if there are many entries. Sample Request: 
const customers = await modempay.customers.list({ limit: 2 });

// or list by matching terms
const customers = await modempay.customers.list({ limit:2, search: "caleb" })
Sample Response:
