API (Application Programming Interface)

An application programming interface (API) defines how software components can request data or actions from each other. In business integrations, web APIs commonly expose endpoints with documented request formats, authentication and responses.

Buyers should check whether those interfaces cover the records and actions their workflow needs, rather than treating the presence of an API as proof that every integration is possible.

A practical example

Example: before selecting a lifecycle platform, an ops architect reviews its API reference and confirms it can read and write contact records and trigger workflows.

A competing tool only exposes read endpoints, which would force manual updates for one core process.

What to evaluate before investing

  • Review the API reference yourself: confirm endpoints exist for the exact objects and actions your workflows need, including writes.
  • Ask about rate limits (how many requests per minute are allowed) and whether they fit your expected automation volume.
  • Check versioning policy: how long old API versions are supported so your integrations do not break on vendor updates.

Limitations and tradeoffs

A documented API does not guarantee a maintained one; thin coverage, aggressive rate limits, or frequent breaking changes can make integrations costly to keep alive.
