Obtaining your secret key
First, select the site you need the secret key for in the site switcher (top left directly under the Hitprobe logo). Then select Manage site from the menu. You'll find your secret key under the Integration section. Copy this key so you can use it shortly.
info
The secret key is in a UUID format, so it should look something like this:
4d5d94e5f2e9-7408-4fee-9e42-3748eaee
.
danger
The secret key is only to be used server side and should be protected as a credential just like any other authentication token.
