Questions
Rex and RelationCity, answered
What can start an automation from Rex?
Any of Rex's 14 triggers in the catalog, including Appraisal Created, Calendar Event Created, Calendar Event Updated and Contact Created. Describe the moment in plain language and your agent picks the right one.
What can your agent do in RelationCity when something happens in Rex?
Any of RelationCity's 7 actions, including Create Contact, Update Contact, Update Custom Date Field and Update Custom Text Field. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from RelationCity to Rex?
RelationCity has no triggers in the catalog today, so automations start in Rex. If you need the other direction, ask: your agent reads RelationCity's API documentation and adds it.
Do I have to build a connector for Rex or RelationCity?
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 Rex and RelationCity 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.
