Check Refund Availability (GET)

GET 
/api/v1/pbl/check-refund-availability/:service/:transaction_id/:checksum

GET variant of the refund availability check. Checks the full transaction amount.

Important: validation and checksum verification read the query string, not the path segments - the same values must therefore also be passed as query parameters (?service=...&transaction_id=...&checksum=...). We recommend using the POST variant instead.

Checksum

sha256({service}|{transaction_id}|{SecretHash})

Business refusal - transaction not paid. Same body envelope as 400: an availability answer, not an auth error.

Business refusal - transaction already refunded. Same body envelope as 400.
