# BulkCreateCustomers

`POST /v2/customers/bulk-create`

Creates multiple [customer profiles](entity:Customer) for a business.

This endpoint takes a map of individual create requests and returns a map of responses.

You must provide at least one of the following values in each create request:

- `given_name`
- `family_name`
- `company_name`
- `email_address`
- `phone_number`

## Request body

- BulkCreateCustomersRequest — Defines the body parameters that can be included in requests to the [BulkCreateCustomers](api-endpoint:Customers-BulkCreateCustomers) endpoint.
  - `customers` object, required — A map of 1 to 100 individual create requests, represented by `idempotency key: { customer data }` key-value pairs. Each key is an [idempotency key](https://developer.squareup.com/docs/build-basics/common-api-patterns/idempotency) that uniquely identifies the create request. Each value contains the customer data used to create the customer profile.

## Response `200`

Success

- BulkCreateCustomersResponse — Defines the fields included in the response body from the [BulkCreateCustomers](api-endpoint:Customers-BulkCreateCustomers) endpoint.
  - `responses` object — A map of responses that correspond to individual create requests, represented by key-value pairs. Each key is the idempotency key that was provided for a create request and each value is the corresponding response. If the request succeeds, the value is the new customer profile. If the request fails, the value contains any errors that occurred during the request.
  - `errors` Error[] — Any top-level errors that prevented the bulk operation from running.
    - `category` 'API_ERROR' | 'AUTHENTICATION_ERROR' | 'INVALID_REQUEST_ERROR' | 'RATE_LIMIT_ERROR' | 'PAYMENT_METHOD_ERROR' | 'REFUND_ERROR' | 'MERCHANT_SUBSCRIPTION_ERROR' | 'EXTERNAL_VENDOR_ERROR', required — Indicates which high-level category of error has occurred during a request to the Connect API.
