Capture Context Components {#uc-capture-context-features}
=========================================================

The capture context is a signed JSON Web Token (JWT) containing this information:

* Merchant-specific parameters that dictate the customer payment experience for the current payment transaction.
* A one-time public key that secures the information flow during the current payment transaction.

There are some components of `Unified Checkout` that are available in the API, the `Business Center` or both. For information about how to configure `Unified Checkout` using the `Business Center`, see [Configure the Unified Checkout Merchant Experience](/docs/vas/en-us/unified-checkout/developer/all/rest/unified-checkout/uc-intro-setup/uc-intro-setup-ebc.md ""). For information about which fields are available using the API or the `Business Center`, and when one is overridden by the other, see [Capture Context Fields in the Business Center](/docs/vas/en-us/unified-checkout/developer/all/rest/unified-checkout/uc-intro-setup/uc-intro-setup-ebc/uc-ebc-api-info.md ""). For a full capture context with all possible fields, see [Example: Unified Checkout Complete Capture Context](/docs/vas/en-us/unified-checkout/developer/all/rest/unified-checkout/uc-setup-capture-context/uc-appendix-complete-cc-ex.md "").
Use these required fields to request the capture context:

allowedPaymentTypes
:

clientVersion
:

country
:

locale
:

data.orderInformation.amountDetails.currency
:

data.orderInformation.amountDetails.totalAmount
:

targetOrigins
:
The URL in this field value must contain `https`.
This example shows the minimum fields that must be included in the capture context:

```
{
  "targetOrigins": [
    "http://localhost:8080"
  ],
  "country": "US"
  "locale": "en_US"
  "data": {
    "orderInformation": {
      "amountDetails": {
        "totalAmount": "21.00",
        "currency": "USD"
      }
    }
  }
}
```

> IMPORTANT  
> ` Visa Acceptance Solutions ` recommends that you dynamically parse the response for the fields that you are looking for when you integrate with ` Visa Acceptance Solutions ` APIs. ` Visa Acceptance Solutions ` may add additional fields in the future.  
> You must ensure that your integration can handle new fields that are returned in the response. Even though the underlying data structures do not change, you must also ensure that your integration can handle changes to the order in which the data is returned. ` Visa Acceptance Solutions ` uses semantic versioning practices, which enables you to retain backwards compatibility as new fields are introduced in minor version updates.
