Connect Upsales to Retell AI
When New Activity fires in Upsales, your agent runs Add Agent in Retell AI. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

Questions
Upsales and Retell AI, answered
What can start an automation from Upsales?
Any of Upsales's 6 triggers in the catalog, including New Activity, New Appointment, New Company and New Contact. 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 Upsales?
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 Upsales?
Retell AI has no triggers in the catalog today, so automations start in Upsales. 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 Upsales 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 Upsales 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.
