Connect MailerLite and FreeAgent
When Subscriber Added to Group fires in MailerLite, your agent runs Create Contact in FreeAgent, or New Bank Transaction in FreeAgent to Change Subscriber Email in MailerLite. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

Questions
MailerLite and FreeAgent, answered
What can start an automation from MailerLite?
Any of MailerLite's 10 triggers in the catalog, including Subscriber Added to Group, Subscriber Completed Automation, Subscriber Created and Subscriber Fields Updated. Describe the moment in plain language and your agent picks the right one.
What can your agent do in FreeAgent when something happens in MailerLite?
Any of FreeAgent's 50 actions, including Create Bill, Create Contact, Create Credit Note and Create Estimate. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from FreeAgent to MailerLite?
Yes. When something happens in FreeAgent, your agent can act in MailerLite too. This page covers both directions: FreeAgent's triggers and MailerLite's actions are listed here as well.
Do I have to build a connector for MailerLite or FreeAgent?
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 FreeAgent 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. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
