Any of Reply's 7 triggers in the catalog, including New Email Opened, New Emails Sent, New Link Clicked and New Person Bounce. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Slack when something happens in Reply? Any of Slack's 60 actions, including Create Canvas, Create Channel, Create Channel Canvas and Create Reminder. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Slack to Reply? Yes. When something happens in Slack, your agent can act in Reply too. This page covers both directions: Slack's triggers and Reply's actions are listed here as well. ### ### Do I have to build a connector for Reply or Slack? 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 Reply and Slack 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.
