This response has no body data.
This endpoint is ideal for low-code integrations, and can be used in place of Fetch Trade URL, which returns the trade url in JSON. Instead, the Start trade endpoint automatically resolves to the trade URL, and is best used to initiate trades within a browser or webview. To initiate orders natively via the API, use:
