# Web API Fuzz Testing **(ULTIMATE)**
You can add web API fuzzing to your [GitLab CI/CD](../../../ci/README.md)
pipelines. This helps you discover bugs and potential security issues that other QA processes may

Web API fuzzing performs fuzz testing of API operation parameters. Fuzz testing sets operation
parameters to unexpected values in an effort to cause unexpected behavior and errors in the API
backend.
backend. This helps you discover bugs and potential security issues that other QA processes may
miss.
We recommend that you use fuzz testing in addition to [GitLab Secure](../index.md)'s
other security scanners and your own test processes. If you're using [GitLab CI/CD](../../../ci/README.md),
you can run fuzz tests as part your CI/CD workflow.
## Requirements
## When Web API fuzzing runs
Web API fuzzing runs in the `fuzz` stage of the CI/CD pipeline. To ensure API fuzzing scans the
latest code, your CI/CD pipeline should deploy changes to a test environment in one of the stages
preceding the `fuzz` stage.
Note the following changes have been made to the API fuzzing template:
- In GitLab 14.0 and later, you must define a `fuzz` stage in your `.gitlab-ci.yml` file.
- In GitLab 13.12 and earlier, the API fuzzing template defines `build`, `test`, `deploy`, and
`fuzz` stages. The `fuzz` stage runs last by default. The predefined stages were deprecated, and removed from the `API-Fuzzing.latest.gitlab-ci.yml` template. They will be removed in a future GitLab
version.
If your pipeline is configured to deploy to the same web server on each run, running a
pipeline while another is still running could cause a race condition in which one pipeline
overwrites the code from another. The API to scan should be excluded from changes for the duration
of a fuzzing scan. The only changes to the API should be from the fuzzing scanner. Any changes made
to the API (for example, by users, scheduled tasks, database changes, code changes, other pipelines,
or other scanners) during a scan could cause inaccurate results.
You can run a Web API fuzzing scan using the following methods:
- [OpenAPI Specification](#openapi-specification) - version 2.0 or 3.0
- [HTTP Archive](#http-archive-har) (HAR)
- [Postman Collection](#postman-collection) - version 2.0 or 2.1
Example projects using these methods are available:
- [Example OpenAPI v2 Specification project](https://gitlab.com/gitlab-org/security-products/demos/api-fuzzing-example/-/tree/openapi)

## When fuzzing scans run
WARNING:
**NEVER** run fuzz testing against a production server. Not only can it perform *any* function that
the API can, it may also trigger bugs in the API. This includes actions like modifying and deleting
data. Only run fuzzing against a test server.
When using the `API-Fuzzing.gitlab-ci.yml` template, the `fuzz` job runs last, as shown here. To
ensure API fuzzing scans the latest code, your CI pipeline should deploy changes to a test
environment in one of the jobs preceding the `fuzz` job:
To enable Web API fuzzing:
```yaml
stages:
- build
- test
- deploy
- fuzz
```
Note that if your pipeline is configured to deploy to the same web server on each run, running a
pipeline while another is still running could cause a race condition in which one pipeline
overwrites the code from another. The API to scan should be excluded from changes for the duration
of a fuzzing scan. The only changes to the API should be from the fuzzing scanner. Be aware that
any changes made to the API (for example, by users, scheduled tasks, database changes, code
changes, other pipelines, or other scanners) during a scan could cause inaccurate results.
## Configuration
- Include the API fuzzing template in your `.gitlab-ci.yml` file.
- From GitLab 13.10 and later, use the Web API fuzzing configuration form.
There are three ways to perform scans. See the configuration section for the one you wish to use:
- For manual configuration instructions, see the respective section, depending on the API type:
- [OpenAPI Specification](#openapi-specification)
- [HTTP Archive (HAR)](#http-archive-har)
- [Postman Collection](#postman-collection)
- Otherwise, see [Web API fuzzing configuration form](#web-api-fuzzing-configuration-form).
- [OpenAPI v2 or v3 specification](#openapi-specification)
- [HTTP Archive (HAR)](#http-archive-har)
- [Postman Collection v2.0 or v2.1](#postman-collection)
In GitLab 14.0 and later, API fuzzing configuration files must be in your repository's
`.gitlab` directory instead of your repository's root.
Examples of both configurations can be found here:
- [Example OpenAPI v2 specification project](https://gitlab.com/gitlab-org/security-products/demos/api-fuzzing-example/-/tree/openapi)
- [Example HTTP Archive (HAR) project](https://gitlab.com/gitlab-org/security-products/demos/api-fuzzing-example/-/tree/har)
- [Example Postman Collection project](https://gitlab.com/gitlab-org/security-products/demos/api-fuzzing/postman-api-fuzzing-example)
- [Example GraphQL project](https://gitlab.com/gitlab-org/security-products/demos/api-fuzzing/graphql-api-fuzzing-example)
WARNING:
GitLab 14.0 will require that you place API fuzzing configuration files (for example,
`gitlab-api-fuzzing-config.yml`) in your repository's `.gitlab` directory instead of your
repository's root. You can continue using your existing configuration files as they are, but
starting in GitLab 14.0, GitLab will not check your repository's root for configuration files.

### Error, the OpenAPI document is not valid. Errors were found during validation of the document using the published OpenAPI schema
At the start of an API Fuzzing job the OpenAPI specification is validated against the [published schema](https://github.com/OAI/OpenAPI-Specification/tree/master/schemas). This error is shown when the provided OpenAPI specification has validation errors. Errors can be introduced when creating an OpenAPI specification manually, and also when the schema is generated.

1. Alternatively, you can check the log output and look for schema validation warnings. They are prefixed with messages such as `OpenAPI 2.0 schema validation error` or `OpenAPI 3.0.x schema validation error`. Each failed validation provides extra information about `location` and `description`. Correct each of the validation failures and then resubmit the OpenAPI doc. Note that JSON Schema validation message might not be easy to understand. This is why we recommend the use of editors to validate document.
1. Once the validation issues are resolved, re-run your pipeline.
