Customer Fields has no triggers in the catalog today, so automations start in MailerLite. If you need the other direction, ask: your agent reads Customer Fields's API documentation and adds it. ### ### Do I have to build a connector for MailerLite or Customer Fields? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use MailerLite and Customer Fields without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes.
