FAQ

API Integration FAQs

Zapier or custom code?

Zapier and Make are great for simple flows. For high volume or complex logic, custom code is cheaper and more reliable over time.

Can you connect a tool without a public API?

Often yes, through webhooks, exports or email parsing. We’ll tell you honestly after checking.

Do you maintain integrations?

Yes, as part of a monthly maintenance or automation plan.
