Any of Pennylane's 34 actions, including Create Company Customer V2, Create Customer Invoice V2, Create Individual Customer V2 and Create Product V2. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Pennylane to MailerLite?
Yes. When something happens in Pennylane, your agent can act in MailerLite too. This page covers both directions: Pennylane's triggers and MailerLite's actions are listed here as well.
Do I have to build a connector for MailerLite or Pennylane?
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 MailerLite and Pennylane 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.
