}Order forms
Mark an order form as signed
This endpoint records the customer’s signature on an order form, and creates the order that carries the quoted deal out.
Only a generated order form can be signed, so a 422 is returned once the order form has been signed, has expired or has been voided.
An execute_at landing on or after the day the quoted deal stops being executable is rejected as well, so the order can never be scheduled past the term it bills.
A concurrent write on the same quote is reported as a 422 rather than retried, so a duplicated call can fail while the first one is still in flight.
This is a premium feature.

Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Path Parameters
Unique identifier assigned to the order form within the Lago application. This ID is exclusively created by Lago and serves as a unique identifier for the order form's record within the Lago system.
Example:
"1a901a90-1a90-1a90-1a90-1a901a901a90"
Body
application/json
Mark order form as signed payload
Parameters available when marking an order form as signed. Every parameter is optional, so an empty body records the signature without attaching a document, and creates an order that is not scheduled for execution.
