Questions
CallRail and Rex, answered
What can start an automation from CallRail?
Any of CallRail's 5 triggers in the catalog, including Outbound Call Completed, SMS Received, Form Captured and Phone Call Started. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Rex when something happens in CallRail?
Any of Rex's 7 actions, including Create Lead, Create Match Profile, Create Note and Create Reminder. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Rex to CallRail?
Rex has no triggers in the catalog today, so automations start in CallRail. If you need the other direction, ask: your agent reads Rex's API documentation and adds it.
Do I have to build a connector for CallRail or Rex?
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 CallRail and Rex without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in Rex 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.
