Creates a form hook transaction.
A form hook allows you to send data to Kustomer by posting to the form hook's designated endpoint.
This endpoint can be generated by creating a form hook with the Kustomer API or within a workflow.
Currently, form hooks accept Form-Data content, JSON, and XML payloads.
Form hooks do not require any authentication and are best suited for use in public HTML forms or anywhere authenticity of the sender is not important.
The size of the request body cannot exceed 400kb. Transactions exceeding this size will fail with a 413 error.
