Integration
Connect Rex and Xero
When Appraisal Created fires in Rex, your agent runs Add purchase order in Xero, or New bill in Xero to Create Lead in Rex. 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.
Build solutions, not workarounds.

Questions
Rex and Xero, 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 Xero when something happens in Rex?
Any of Xero's 26 actions, including Create bank transaction, Create bill, Create or update contact and Create payment. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Xero to Rex?
Yes. When something happens in Xero, your agent can act in Rex too. This page covers both directions: Xero's triggers and Rex's actions are listed here as well.
Do I have to build a connector for Rex or Xero?
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 Xero 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.
