Any of Slack's 15 triggers in the catalog, including New Channel, New Channel (instant), New Channel Member and New File (instant). Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Posh when something happens in Slack? Any of Posh's 12 actions, including Create Contact, Create Email Assist, Send SMS and Update contact. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Posh to Slack? Posh has no triggers in the catalog today, so automations start in Slack. If you need the other direction, ask: your agent reads Posh's API documentation and adds it. ### ### Do I have to build a connector for Slack or Posh? 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 Slack and Posh 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.
