API Security Best Practices for Growing Teams

What to assess An API key identifies a caller; it does not automatically authorize that caller to access every record. Check object-level permissions for each operation.

How to apply it Validate inputs, constrain output fields, and use HTTPS. Store secrets outside source code and rotate credentials after exposure or staff changes.

Operational considerations Rate limiting and abuse monitoring can reduce misuse, but limits should consider legitimate clients. Log enough to investigate without recording sensitive tokens or payloads.

Next step Document endpoints and test different roles. Review changes to permission logic whenever new routes, partner integrations, or data fields are introduced.
