Glossary Term
What Is an API?
An API, or Application Programming Interface, is a set of rules that lets two software systems communicate directly through code. APIs allow custom, reliable connections between platforms that do not have a native integration.
In Detail
APIs are the most customizable integration method but require development and ongoing maintenance.
Use APIs for custom or critical connections where reliability and control matter more than setup convenience.

Frequently Asked Questions
When should I use an API?+
Use an API for custom or critical connections where reliability and control matter more than setup convenience.
What is the difference between an API and a webhook?+
An API lets you request data on demand; a webhook sends data automatically when an event occurs. Both connect platforms without a third-party tool.
Do API connections require maintenance?+
Yes. API versions, authentication tokens, and data mappings can change, so API connections need monitoring and occasional updates to keep working.
Is an API integration more reliable than Zapier?+
A well-built API connection avoids a third-party dependency and its plan limits, but it requires development and upkeep — best for critical, high-volume flows.
