# Execute

Use the execute call to execute a process to split an invoice into multiple invoices. The original invoice must be in draft status. The resulting invoices are called split invoices.

To access this feature, see Enable Splitting Invoices for steps. 

To split a draft invoice into multiple split invoices:

1. Use the create call to create a single InvoiceSplit object to collect all of the InvoiceSplitItem objects.
2. Use the create call to create a separate InvoiceSplitItem object for each split invoice that you want to create from the original draft invoice.
3. Use the execute call to split the draft invoice into multiple split invoices.

You need to create InvoiceSplitItem objects and an InvoiceSplit object before you can use the execute call. 

* Supported objects: InvoiceSplit
* Asynchronous process: yes

## Header parameters:

  - `Idempotency-Key` (string)
    Specify a unique idempotency key if you want to perform an idempotent POST or PATCH request. Do not use this header in other request types. 

With this header specified, the Zuora server can identify subsequent retries of the same request using this value, which prevents the same operation from being performed multiple times by accident.

  - `Accept-Encoding` (string)
    Include the Accept-Encoding: gzip header to compress responses as a gzipped file. It can significantly reduce the bandwidth required for a response. 

If specified, Zuora automatically compresses responses that contain over 1000 bytes of data, and the response contains a Content-Encoding header with the compression algorithm so that your client can decompress it.

  - `Content-Encoding` (string)
    Include the Content-Encoding: gzip header to compress a request. With this header specified, you should upload a gzipped file for the request payload instead of sending the JSON payload.

  - `Authorization` (string)
    The value is in the Bearer {token} format where {token} is a valid OAuth token generated by calling Create an OAuth token.

  - `Zuora-Entity-Ids` (string)
    An entity ID. If you have Zuora Multi-entity enabled and the OAuth token is valid for more than one entity, you must use this header to specify which entity to perform the operation in. If the OAuth token is only valid for a single entity, or you do not have Zuora Multi-entity enabled, you do not need to set this header.

  - `Zuora-Track-Id` (string)
    A custom identifier for tracing the API call. If you set a value for this header, Zuora returns the same value in the response headers. This header enables you to associate your system process identifiers with Zuora API calls, to assist with troubleshooting in the event of an issue.

The value of this field must use the US-ASCII character set and must not include any of the following characters: colon (:), semicolon (;), double quote ("), and quote (').

  - `X-Zuora-WSDL-Version` (string)
    Zuora WSDL version number.

## Query parameters:

  - `rejectUnknownFields` (boolean)
    Specifies whether the call fails if the request body contains unknown fields.
With rejectUnknownFields set to true, Zuora returns a 400 response if
the request body contains unknown fields. The body of the 400 response is:

json
{
    "message": "Error - unrecognised fields"
}


By default, Zuora ignores unknown fields in the request body.

## Request fields (application/json):

  - `ids` (array, required)
    The ID of the object. Values: a valid InvoiceSplit object ID.
    Example: ["2c93808457d787030157e031d5844c53"]

  - `synchronous` (boolean, required)
    Indicates if the call is synchronous or asynchronous. Values: false

  - `type` (string, required)
    Specifies the type of executed item.
    Enum: "InvoiceSplit"

## Response 200 fields (application/json):

  - `Errors` (array)

  - `Errors.Code` (string)

  - `Errors.Message` (string)

  - `Id` (string)
    The ID of the object in the call. The value is the same as the value you provide in the ids field for the request.

  - `Success` (boolean)
    Returns true if the call was processed successfully, otherwise false.

## Response 401 fields (application/json):

  - `message` (string)
    Error message.

If the error message is "Authentication error", ensure that the Authorization request header contains valid authentication credentials, then retry the request. See [Authentication](https://developer.zuora.com/rest-api/general-concepts/authentication/) for more information.

If the error message is "Failed to get user info", retry the request.
