Questions
DoorLoop and fastbill, answered
What can start an automation from DoorLoop?
Any of DoorLoop's 13 triggers in the catalog, including New Expense, New Lease Charge, New Owner and New Property. Describe the moment in plain language and your agent picks the right one.
What can your agent do in fastbill when something happens in DoorLoop?
Any of fastbill's 18 actions, including Create Customer, Create Invoice, Create Offer and Create Revenue. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from fastbill to DoorLoop?
fastbill has no triggers in the catalog today, so automations start in DoorLoop. If you need the other direction, ask: your agent reads fastbill's API documentation and adds it.
Do I have to build a connector for DoorLoop or fastbill?
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 DoorLoop and fastbill 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.
