Any of Xero's 4 triggers in the catalog, including New bill, New or updated contact, New payment and New sales invoice. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in BIGContacts when something happens in Xero? Any of BIGContacts's 9 actions, including Create or Update Contact, Create or Update Task, Find Contacts by criteria and Get Contact. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from BIGContacts to Xero? BIGContacts has no triggers in the catalog today, so automations start in Xero. If you need the other direction, ask: your agent reads BIGContacts's API documentation and adds it. ### ### Do I have to build a connector for Xero or BIGContacts? 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 Xero and BIGContacts 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.
