After the payer has completed their payment and returned to the CompleteUrl,
you need to validate that the payment has the status Paid so you are able to
capture funds.
First of all, you need to find out if the transaction type needs to be captured
or not. An Authorization needs to be captured (most payment
methods generate these type of transactions), a Sale does not (Trustly and
Swish transactions where the funds are captured instantly and automatically).
Perform the GET
You can do this by perfoming a GET on your payment.
The status field should simply have the status Paid. As long as this is the
case, you are good to go and proceed to doing the capture.
We also recommend adding an expansion of the paid node. Do this by adding
?$expand=paid after the paymentOrderId. This way, you can retrieve more
information about the payment while limiting the amount of calls you have to do
towards the API.
Not adding the expansion will result in the same response, apart from the paid node being collapsed.

Other Statuses
There are several statuses the payment might have in addition to Paid once the
payer has reached the completeURL. If any of these appear, no capture is
available. You can get more information by doing a GET with the field expanded
or directly towards the resource, just like we showed above. The other statuses
are:
Failed
Returned when a payment has failed. You will find an error message in
the Failed response.
Cancelled
Returned when an authorized amount has been fully cancelled. It will contain
fields from both the cancelled description and paid section.
See the Cancelled response.
Aborted
Returned when the merchant has aborted the payment, or if the payer cancelled
the payment in the redirect integration. See the Aborted response.
