### Request Access {#request-access}

To use the ABU API, your organization must first be registered with Mastercard's ABU Program. The ABU API is only for registered Acquirers, Large Card-on-File/Recurring Payment Merchants, and Payment Facilitators.

#### Mastercard Acquirers {#mastercard-acquirers}

Submit a signed ABU customer form available on Mastercard Connect (form 806). Depending on usage needs, acquirers can utilize either ABU bulk file requests and/or the ABU API to obtain updates for their card-on-file and recurring payment merchants. See the ABU Reference Guide on Mastercard Connect for more information.

#### Large Card-on-File/Recurring Payment Merchants, and Payment Facilitators {#large-card-on-filerecurring-payment-merchants-and-payment-facilitators}

Contact your acquirer about leveraging the ABU API via their ABU integration. Alternately only for very large merchants and Service Providers you may qualify for an ABU direct connection. Contact your Mastercard representative for more information about this option.
