Connect Pennylane to Retell AI

Questions
Pennylane and Retell AI, answered
What can start an automation from Pennylane?
Any of Pennylane's 5 triggers in the catalog, including New Billing Subscription V2, New Customer Invoice V2, New Customer V2 and New Product V2. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Retell AI when something happens in Pennylane?
Any of Retell AI's 27 actions, including Create Knowledge Base, Create Retell LLM, Update Agent and Update Call. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Retell AI to Pennylane?
Retell AI has no triggers in the catalog today, so automations start in Pennylane. If you need the other direction, ask: your agent reads Retell AI's API documentation and adds it.
Do I have to build a connector for Pennylane or Retell AI?
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 Pennylane and Retell AI 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.
