This endpoint is scheduled for deprecation. Please refer to the V2 Business Onboarding API The first step in using GrailPay is onboarding new or existing businesses to create user accounts. GrailPay will then return a UUID, which serves as the unique identifier for each business, to be used for further requests. Please note that only one business can be created per request. The registration information typically includes details such as the user’s phone, address, bank account etc. The API does not require the user’s address, and business detail unless should_do_kyb is set to true. While bank account details are optional in the registration API, they are required for processing transactions for your customers. If a user did not provide their bank account information during registration, you can still add it later using the Add Bank Account API. GrailPay offers a service to connect customer bank accounts with the GrailPay Bank Link Widget. Please refer to your client agreement if this service is included in your service package.
It is recommended to send all available KYB data for at least one side of each transaction.The following KYB data is required: Exact business entity name Business tax ID number (EIN) Business Address

Billing

GrailPay’s API supports associating specific billable events with a particular merchant, enabling precise attribution for billing purposes. This feature allows you to link the UUID of a user tied to a merchant (a business that has undergone KYB verification) to the billing event recorded for the API call. To attribute the billing event to a merchant, include the following parameter in your request payload:
  • billing_merchant_user_uuid: The unique identifier (UUID) of the user associated with the merchant to whom this billable event should be attributed.
By leveraging this parameter, you can ensure accurate and detailed tracking of billable events across your integrations.
