Any of Campaign Monitor's 3 triggers in the catalog, including New client, New list and New subscriber. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Google Cloud Pubsub when something happens in Campaign Monitor? Any of Google Cloud Pubsub's 4 actions, including Create Topic, List Topics, Publish Message and Pull Messages. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Google Cloud Pubsub to Campaign Monitor? Google Cloud Pubsub has no triggers in the catalog today, so automations start in Campaign Monitor. If you need the other direction, ask: your agent reads Google Cloud Pubsub's API documentation and adds it. ### ### Do I have to build a connector for Campaign Monitor or Google Cloud Pubsub? 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 Campaign Monitor and Google Cloud Pubsub 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.
