API

A defined interface for software to call another system's functions or data. Most B2B tools expose a REST API for integrations.

Frequently asked questions

Why does a sales tool need an API?
So RevOps can move data between systems without manual exports, build custom workflows, and integrate the tool into a composable revenue stack. Without an API, the tool is a silo and the integration cost is permanent.
What's the difference between a REST API and GraphQL?
REST exposes fixed endpoints; GraphQL lets clients ask for exactly the fields they need in one request. For most B2B integrations, REST is plenty; GraphQL matters when you're doing complex reads across many entities.
How should an API be authenticated for B2B SaaS?
OAuth 2.0 for user-context access, bearer tokens for server-to-server. API keys without rotation are increasingly unacceptable for enterprise buyers. Security reviews now flag long-lived static keys.
How do you know if an API is good enough to bet on?
Read the docs first. Good APIs have versioning, rate limits documented in headers, clear error responses, and a changelog with deprecation notices. Bad APIs ship features but not breaking-change discipline.
What's the cost of choosing a sales tool without a good API?
Permanent integration debt. Every cross-system workflow becomes manual export and import. Every new tool added to the stack requires custom glue. RevOps teams end up maintaining shadow scripts that break every time the vendor changes its UI.
