Questions
Buttondown and Kartra, answered
What can start an automation from Buttondown?
Any of Buttondown's 4 triggers in the catalog, including New Draft, New Scheduled Email, New Tag and Newsletters. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Kartra when something happens in Buttondown?
Any of Kartra's 23 actions, including Create New Lead, Assign Tag to Lead, Edit Lead and Edit Subscription. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Kartra to Buttondown?
Kartra has no triggers in the catalog today, so automations start in Buttondown. If you need the other direction, ask: your agent reads Kartra's API documentation and adds it.
Do I have to build a connector for Buttondown or Kartra?
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 Buttondown and Kartra 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.
