Any of Microsoft Teams's 27 actions, including Create Meeting, Create Team, Update Channel Message and Update Chat Message. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Microsoft Teams to Harpoon? Microsoft Teams has no triggers in the catalog today, so automations start in Harpoon. If you need the other direction, ask: your agent reads Microsoft Teams's API documentation and adds it. ### ### Do I have to build a connector for Harpoon or Microsoft Teams? 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 Harpoon and Microsoft Teams 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.
