Authentifizierungsfehler auf Crypto.com Austausch API -Anfrage Python ⇐ Python

[Anonymous]

Ich versuche, ein grundlegendes Handelsskript auf Crypto.coms Austausch zu testen, und ich erhalte diese Nachricht immer wieder. Authentifizierungsfehler '}
Bestellungsreaktion kaufen: {' Code ': 40101,' Nachricht ':' Authentifizierungsfehler '} < /p>
Ich habe versucht, ein paar neue API -Schlüssel und ein paar neue API -Tasten zu erstellen und zu erstellen. Stellen Sie sicher, dass ich sie genau kopiere und ich bekomme immer noch den gleichen Fehler. Ich denke, mit meiner digitalen Signatur stimmt etwas nicht, aber ich bin mir nicht sicher, was es ist. Mein Problem beim Lesen. entfernt.
