🔵 Notes

Because your master app key is shown only when you generate it, save your master app key in a secure location if you plan to use it more than once. The term "master application key ID" was formerly called an "account ID." If you use an integration in which the terminology was not updated to reflect this change, the master application key ID works in place of your account ID. For a standard app key, you can use that key's keyID in place of an account ID. You can find your master app key ID on the Application Keys page.

⚠️ Attention

It is important to perform a connection test to verify that the Backblaze host can be successfully reached. Once the discovery process is complete, the connection details will be visible on the Assets page.
