Connect Watermelon and Xero
When New Contact fires in Watermelon, your agent runs Create or update contact in Xero, or New bill in Xero to Add Contact in Watermelon. 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
Watermelon and Xero, answered
What can start an automation from Watermelon?
Any of Watermelon's 6 triggers in the catalog, including New Contact, New Conversation, Updated Contact and Handover Conversation Agent. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Xero when something happens in Watermelon?
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 Watermelon?
Yes. When something happens in Xero, your agent can act in Watermelon too. This page covers both directions: Xero's triggers and Watermelon's actions are listed here as well.
Do I have to build a connector for Watermelon 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 Watermelon 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.
