Questions
Square and Railway, answered
What can start an automation from Square?
Any of Square's 3 triggers in the catalog, including New order, New or updated customer and New payment. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Railway when something happens in Square?
Any of Railway's 16 actions, including Update service, Update variables, Add domain and Add environment. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Railway to Square?
Railway has no triggers in the catalog today, so automations start in Square. If you need the other direction, ask: your agent reads Railway's API documentation and adds it.
Do I have to build a connector for Square or Railway?
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.
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.
