Complete Mandate {#uc_cc_complete_mandate}
==========================================

The complete mandate feature provides service orchestration within `Unified Checkout` and simplifies your integration. Service orchestration enables `Unified Checkout` to orchestrate services on your behalf. The complete mandate feature provides instructions to the unifiedPayment.complete() method in the JavaScript. You must include both the unifiedPayment.complete() object in the Javascript and the completeMandate field object in your capture context to enable `Unified Checkout` to initiate services on your behalf from the browser.

> IMPORTANT
> If you are updating an existing ` Unified Checkout ` configuration to use the complete mandate, you must update your JavaScript to include the unifedPayment.complete() function.
> IMPORTANT
> When the billingType field is set to ` NONE ` you must include the required fields within the capture context request to ensure that the required fields are included for payment processing. For information about the fields that are required for payment services, see the [Payments Developer Guide](https://developer.visaacceptance.com/docs/vas/en-us/payments/developer/ctv/rest/payments/payments-intro.md "").
