Questions
Quaderno and Hunter, answered
What can start an automation from Quaderno?
Any of Quaderno's 3 triggers in the catalog, including New Contact, New Invoice and New Sale. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Hunter when something happens in Quaderno?
Any of Hunter's 13 actions, including Create email opened webhook, Create Lead, Update Lead and Count Email. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Hunter to Quaderno?
Hunter has no triggers in the catalog today, so automations start in Quaderno. If you need the other direction, ask: your agent reads Hunter's API documentation and adds it.
Do I have to build a connector for Quaderno or Hunter?
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 Quaderno and Hunter 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.
