What is a Merchant?
A Merchant in the GrailPay ACH API is a business entity that has completed Know Your Business (KYB) verification and is eligible to receive or process ACH payments. Merchants typically operate within a vendor’s ecosystem and are often attributed to specific billing events and revenue-sharing flows. Once onboarded, a merchant is uniquely identified by auuid
associated with the user record. This identifier is
required for actions such as initiating attributing billable events and retrieving usage data.
A merchant is a specialized type of business in the GrailPay ACH API. While the onboarding process is similar to
that of a business, it includes a significant number of additional fields and requirements. If you are transferring funds on behalf of a
merchant entity, it must be onboarded using the merchant registration flow to meet compliance and regulatory
obligations. When creating transfers, at least one side of that transfer must be associated with a KYB-verified merchant.
Step 1: Collect Merchant Information
To create a business we need to collect information about the point of contact and the information about the business itself, you can provide any combination of the following fields:Point of Contact Information
- First name ( point of contact for the business )
- Last name ( point of contact for the business )
- Phone
Business Information
- Name ( legal name of the business )
- EIN ( Employer Identification Number )
- Trading Name (DBA - Doing Business As)
- Entity Type ( e.g. Sole Proprietor, LLC, etc. )
- Incorporation Date ( date when the business was incorporated )
- Incorporation State ( state where the business was incorporated )
- Address ( business address )
- Transaction Fee Percent ( default transaction fee percentage, if applicable )
- Transaction Fee Fixed ( default transaction fee, if applicable )
- Maximum Transaction Fee ( maximum transaction fee that can be charged on a transaction )
Business Owners
At least one beneficial owner is required for KYB verification. You must provide the following fields for each owner:- First Name
- Last Name
- Phone
- DOB ( Date of Birth )
- SSN ( Social Security Number, last 4 or full 9 digits )
- Address
- Is Beneficial Owner ( must be true for at least one owner )
- Is Director
- Is Significant Control Person
- Ownership Percentage
Required Fields for KYB Verification
- Point of Contact Information ( all fields )
- Business Information
- Name
- EIN
- Trading Name
- Address
- Entity Type
- Business Owners ( at least one beneficial owner is required for KYB)
- All Fields
Merchants differ from businesses and individuals in that significantly more information is required to complete
KYB (Know Your Business) verification. While not all fields are mandatory, we strongly recommend providing as much
information as possible to ensure a smooth onboarding experience and to meet regulatory and compliance requirements.
Testing
When testing in GrailPay’s sandbox environment, you can create a merchant as usual. To include a bank account, simply use any random 12-digit account number along with one of our supported test routing numbers. For more details, refer to the Technical Overview guide.Step 2: Provide a Bank Account
You can onboard a merchant with or without a connected bank account. If you choose to provide one, we support two methods:Option A: Link a Plaid Account
If you’re using Plaid for bank account linking, include the following fields:bank_account.plaid.access_token
bank_account.plaid.account_id
Option B: Manual Entry
You can also onboard a person using manually provided account details:account_number
routing_number
account_name
account_type
(checking
orsavings
)
Real-Time Validation (Recommended)
To reduce fraud risk and ensure funds can be successfully routed, we recommend enabling real-time bank account validation during onboarding. This feature is powered by our Account Intelligence product, which provides intelligent validation of routing and account numbers at the time of submission. To enable this, include an actions object in your onboarding request:Step 3: Review the Response
Upon success, you’ll receive a response containing:- The
uuid
of the related to the merchant. This uuid is required for future operations such as linking bank accounts and initiating transfers. - Echoed values such as name and address
- Status of the onboarding
- KYB Status of the Merchant
- An account intelligence object (if validation was requested)
