“Protect server-to-server services with password”
If no password has been created, generate a new password and confirm the changes. Copy the password. (You must then enter this in the Payrexx administration under “Settings” > “Payment provider” > “Datatrans” in the “Merchant password” field.)
Next to the title “Server-to-Server service security” is a link with the name “Security signature”. Please follow this link.
Select the third option “Important parameters will be digitally signed (HMAC-SHA256) and sent with payment messages”. If no HMAC key has been created yet, please generate a new key and confirm the changes. (The HMAC key then must be added to the Datatrans settings.)
