# Grant List API The Grant List API is used as an internal fraud and risk mitigation tool for merchants performing remittance transactions. Merchants can add account information to the Grant List database using the /account operation to let us know which account(s) to use for deposits. Upon receiving the remittance transaction request, Payments-API checks that the account specified in the request exists in the Grant List database for that merchant. The Grant List API requires [Basic Authentication](/gettingstarted#basic-authentication). __Production Server URL: `https://api.nelnetpay.com/grantlist`__ Version: 1.1.5 ## Servers UAT ``` https://api.uat.nelnetpay.com/grantlist ``` ## Security ### bearerAuth Bearer Authentication Token for /check endpoint Type: http Scheme: bearer Bearer Format: JWT ### basicAuth Basic Authentication Username & Password for /account endpoint Type: http Scheme: basic ## Download OpenAPI description [Grant List API](https://docs.nelnetpay.com/_spec/apis/grant-list-api-spec.yaml) ## Other ### Add or Remove an account from Grant List - [POST /account](https://docs.nelnetpay.com/apis/grant-list-api-spec-1/other/addtoachgrantlist.md): Perform a request to add or remove an account from the Grant List.
