I noticed this both before and after recent updates to the Hotel Booking Plugin. I am currently unable to generate REST API keys. The process initializes and shows the keys and QR code, but it’s not saving/storing the keys. This is supported by the fact that I cannot view the keys after completing the process or use the keys/QR code to access bookings via the Hotel Booking Mobile App (iOS) in my case. (Just indicates “No keys found.”)
Thanks for your question. I’ve generated Rest API keys locally with Hotel Booking 4.6.0 and they are saved successfully. The keys did not disappear after I went back and reloaded the page. Please try to contact our support team so we will help you sort this out.
