How do I find my List UID or Campaign UID?

You can retrieve all UIDs by using the `list_subscriber_collections` or `list_email_campaigns` tools. They are also visible in the URL when viewing these resources in your MailWizz dashboard.

Can I add custom fields when subscribing a user?

Yes, include your custom field values (like FNAME, LNAME) within the `subscriber_json` object when using the `add_subscriber_to_list` tool.

This is the full base URL where your MailWizz API is reachable, for example: `https://mail.yourdomain.com/api`. Your token is encrypted at rest and injected securely at runtime.
