Replace Order

Modify an existing order (cancel and replace)

PreviousSyntaxNextSyntax

Last updated 1 year ago

Overview

This PUT endpoint enables you to replace an existing order in AutoShares. The order is sent in the JSON format to our service which in turn replaced the fields in the existing order.

There are six required parameters that must be provided in the request:

  1. Authorization (header). This is the authorization token from the very first token request. The value of this header must have the following format: Bearer BQ898r9fefi (Bearer + 1 space + the token).

  2. API version (path). Unless necessary, leave it at "1.0".

  3. Trading Account ID (path). This is the numeric ID of the trading account on which an existing order must be modified.

  4. existingOrderID (path). This is the internal ID of the replaced order.

  5. body (body of the request). This is a JSON file that contains the parameters that must be modified in an existing order.

Here's the final template for this API request:

  • For orders that will only be verified by the API but not the execution venue (quick):

PUT apiURL/v1.0/accounts/{accountID}/orders/{existingOrderID}
  • For orders that will be verified by the API and the execution venue too (slow):

PUT apiURL/v1.0/accounts/{accountID}/syncorders/{existingOrderID}

Request Body

The body of this request represents the information that must be replaced in an existing order. It must be sent in the JSON format with mandatory parameters about the order and also those parameters that need to be modified.

The first four parameters — ID, Quantity, Price, ExecutionInstructions, Legs — are mandatory, while the remaining parameters should only be provided in case they need to be modified. Apart from these four parameters, the rest of the JSON should be constructed identically to the .

Order Modification Sample

{
  "Id": 178941,
  "Quantity": 5,
  "Price": 49,
  "ExecutionInstructions" : {"Commission": "0.5"}
}

Common Mistakes

Here are some of the common mistakes that developers make when attempting to modify an existing order.

Specifying the User ID Instead of the Trading Account ID

Another common mistake when making this request is specifying the user ID instead of the user's trading account ID. Doing so will result in the 500 status code and the following error message:

{
    "message": "An error occurred while processing your request",
    "error": "Unexpected server error"
}

Specifying a Trading Account of a Different User

It's critical to understand that when you use the authorization token of a particular user in this request's header, only this user's trading accounts can be used for modifying existing orders. Modifying an existing order on a trading account of a different user will lead to the 401 error.

{
    "Message": "Authorization has been denied for this request."
}
