Funkcjonalność wykonywania zwrotów nie jest dostępna w godzinach 00:00 - 06:00 ze względu na wykonywanie w tym czasie procesu rozliczeń/wypłat na konto Merchanta.

Do wygenerowania sygnatury należy użyć secret'u. Aby go otrzymać można go wygenerować samodzielnie w serwisie merchant.inpost.pl lub skontaktować się ze wsparciem dostępnym pod adresem integracjapay@inpost.pl

Nie jest to ten sam client_secret, wykorzystywany w celu otrzymania access_token'u. Pełen opis jak poprawnie wygenerować sygnaturę wiadomości znajduje się poniżej.

            Message signature required to verify genuinity of the request. Calculated by concatenating **X-Command-ID** header value, path variable **transaction_id**, all request body field values (ignoring signature field) in alphanumerical order and a merchant secret (If any of the values is null, then it should be treated as an empty string). Final signature is a lowercase hexadecimal digest of a hash function applied to the concatenated message.
               
            Supported hash functions are: SHA-512
               
            Default hash function: SHA-512
               
            If a non-default hash function is used, then the signature must be prefixed by its ID and '_' character
