This guide will walk you through generating your service account token and finding your domain within Grafana.
Login to your Grafana account. On you address bar, The URL will be similar to: https://nango.grafana.net/a/cloud-home-app. Your domain is the text between https:// and the first forward slash /, which in this case would be nango.grafana.net.
Sign in to Grafana and click Administration in the left-side menu.
Click Users and access.
Click Service accounts.
Click the service account to which you want to add a token.
Click Add service account token.
Enter a name for the token.
(recommended) Select Set expiration date and enter an expiry date for the token.
The expiry date specifies how long you want the key to be valid.
If you are unsure of an expiration date, Grafana recommends that you set the token to expire after a short time, such as a few hours or less. This limits the risk associated with a token that is valid for a long time.
