Update an order that has already been created. The only amount, address and UDF fields can be updated. Address fields can be optionally sent as explained in the /orders API.
The API response is similar to that of the order create API.
Note:
Update order is not recommended once the transaction is initiated to PG. Updating the order amount might lead to order amount mismatch (In case there are retry allowed on same order id).
