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 Postman when something happens in MailerLite? Any of Postman's 26 actions, including Create Collection, Create Environment, Create Folder and Create Mock Server. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Postman to MailerLite? Yes. When something happens in Postman, your agent can act in MailerLite too. This page covers both directions: Postman's triggers and MailerLite's actions are listed here as well. ### ### Do I have to build a connector for MailerLite or Postman? 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 Postman 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.
