Authorization

Authorization is a process of placing a hold on the available credit of the consumer for the requested amount, no settlement will be created.
This process is useful for reserving funds from the consumer, after a successful authorization you will get token in order to create payment transaction based on the funds reserved.
The funds will be reserved until a payment will be made or void will be called to release the funds.

Create an Authorization

Call "transactions/init" in order to create an authorization request and add the "methodType" field with "authorize".
The amount field can be sent blank for future authorization transaction, the amount will be sent later using "authorize" API
