What is Full Send?

Full Send is Flasqo's **most powerful testing mode**: it automatically discovers endpoints, runs 14+ test types in parallel, and generates a unified GPT-4-powered report — all from a single URL.

Perfect for:

What Full Send tests

One scan runs all test types automatically:

1. Smoke Testing

Verifies critical endpoints respond correctly. Checks health, auth, and core CRUD operations.

2. Functional Testing

AI-generated test cases validate response schemas, status codes, and data types for all discovered endpoints.

3. Security Testing

Checks security headers (CORS, CSP, HSTS), SSL configuration, exposed secrets, and common vulnerabilities.

4. Performance Testing

Measures response times, identifies slow endpoints, tests concurrent request handling.

5. Visual Testing (for HTML endpoints)

Captures screenshots of rendered pages, detects visual regressions, checks mobile responsiveness.

6. Contract Validation

If OpenAPI/Swagger spec exists, validates actual responses match declared schema.

Frequently asked questions

What does Full Send do?

Full Send runs every applicable testing module against an API from a single URL with no configuration: discovery, functional, smoke, performance, security, fuzz, contract and chaos. It is designed for the first five minutes with an unfamiliar API.

How long does a Full Send scan take?

Typically a few minutes, depending on how many endpoints discovery finds and whether performance modules are included. Functional and smoke results stream back first, with the slower load and chaos phases completing afterwards.

Is it safe to run against production?

Run it against staging first. Full Send includes write-path and load modules, so pointing it at production can create real records and generate real traffic. Where you must scan production, restrict it to read-only endpoints.
