Payment Order State
The state field on the authorization does not indicate whether a given
transaction was successful or not, it only tells whether the authorization
resource itself is operational or not. To figure out the state of i.e. authorization transactions, you have two options:
Paid Or Failed Operations
You can perform a GET request on the authorization. As long as the
authorization has been completed, successful or not, you will find the
Paid or Failed operation among the operations in the response.
Please note that a authorization where a Failed attempt has been made,
but the payer still has attempts left to complete the authorization, you
won’t see the Failed operation. It will only appear when all attempts have
been made.
Authorization Or Sale Transactions
Find the authorization’s list of transactions either by expanding it when
retrieving the authorization, or by performing a GET request towards the
transactions.id URL.
If you find a transaction with type equal to authorization, with its
state equal to Completed, you can be sure that the amount of the
authorization has been reserved or withdrawn and that the authorization
can be considered successful.
