API

An API is a documented interface that lets software exchange information or request actions.

How it works

Requests follow a contract covering formats, authentication, errors and rate limits. Versions and permissions must be managed to keep an integration reliable.

Hypothetical small business example

A booking system could send a validated event to a CRM instead of requiring someone to retype it.

Benefits and limitations

Connect existing tools and reduce repetitive interventions.

An API may change, become unavailable or charge usage fees. Excessive permissions expose unnecessary data.

Common question

Does an API make every integration possible?

No. Check the functions actually available, required permissions, quotas and whether testing can use synthetic data.
