APIs
An API is a defined way for software systems to request data or actions from one another.
Also called: application programming interface
Definition
An application programming interface defines the requests, responses, authentication and operating rules that another system can use.
Why it matters to the business
APIs often determine whether an implementation can connect existing systems directly instead of relying on manual exports or duplicate entry.
How it works
A client authenticates, sends a request in the documented format and receives a structured response or error. The implementation then handles limits, failures and business rules around that exchange.
Where it appears in real systems
CRM records, reporting data, calendars, messaging platforms, accounting systems and AI providers commonly expose APIs.
Common failure modes
- The required action is not available in the vendor API.
- Authentication permissions are too narrow or too broad.
- The API changes version or behavior.
- Rate limits or transient errors are not handled.
Implementation considerations
- Confirm the required endpoint exists before promising scope.
- Use the narrowest practical authorization.
- Design retries and error visibility.
- Treat vendor limits as part of the implementation boundary.
When it is appropriate
Use an API when a supported system interface can perform the required read or write reliably.
When it is not appropriate
Do not force API integration where a supported native connection or simpler bounded method already satisfies the operating requirement.
Relationship to BYFORCE
Integration Sprint, Reporting and AI Workflow Production may depend on APIs where the participating platforms support them.
