API token (MailerLite)
Log in to MailerLite, open Integrations - Developer API, then create or copy your API token from the dashboard: https://dashboard.mailerlite.com/integrations/api - The token is a long JWT-style string (three segments separated by two dots). Paste the entire token into the API token field on the MailerLite integration tab (no Bearer prefix). Official developer reference: https://developers.mailerlite.com/docs/
Audience group ID
In MailerLite go to Subscribers - Groups. Open the group you want to use: the numeric group ID appears in the page URL or in the group details (depending on your MailerLite UI version). Enter that number in Audience group ID. You may enter several IDs separated by comma or space if you need to add subscribers to multiple groups.
API endpoint
Leave API endpoint empty unless MailerLite or your host requires a different URL. The module defaults to https://connect.mailerlite.com/api/subscribers as documented by MailerLite.
