To change your API key for your Cloudflare integration , you’ll first need to obtain a new API key from your account. You can find instructions on how to obtain an API key HERE .
Then, once you have generated a new key, log in to the mybox panel and, by clicking on your name and surname in the upper right corner, select Settings from the menu .
On the website, go to the Users section and, for the selected profile, click the Actions menu and select Change authorization data from the list .
Complete the form with the email address associated with your Cloudflare account and your new API key, and confirm the change by clicking the Add button .
You should only change your authorization details if you change the email address or global API key assigned to the same Cloudflare user. If you want to use a separate Cloudflare user to configure a different domain, add a new user. If you provide valid details in the form, but for a completely different Cloudflare user, existing domain integrations with Cloudflare will stop working.
