# API Injection Testing
## Purpose
Exploit injection sinks behind API endpoints: SQL injection in JSON-body values, ORDER BY/filter fields, and headers; NoSQL operator injection; command injection reaching OS shells. Confirmed via differential, timing, error, or out-of-band evidence — never via status codes alone.
SSRF through URL-accepting parameters belongs to api-ssrf.
## Preconditions
- Mapped API surface with input-bearing endpoints
- For blind cases: an OOB callback domain (oob_callback tool)
- Backend fingerprint from reconnaissance (DB type determines dialect payloads)
## Attack Surface Signals
- String fields in JSON bodies, query strings, path segments
