# Test target configuration

Test your target configuration before running a scan to avoid common issues that lead to failed scans or incomplete results.

Test the configuration to:

* Confirm Snyk API & Web can access your target.
* Verify login credentials work as expected.
* Identify whether a web application firewall (WAF) or other security measures block traffic.
* Verify the validity of your API schema or collection.
* Discover extra hosts that you need to add to your target.

## Prerequisites

To test target configuration, you must have these permissions:

* `view_target`
* `change_target_settings`
* `start_scan`

## Test configuration from the Targets list

1. Navigate to **Targets** and locate the target to test.
2. Open the **Scan** button dropdown.
3. Select **Test configuration**.

## Test configuration from Target settings

1. Navigate to the target settings page.
2. Click **Test configuration** in the **Login Configuration** or **API Target Authentication** module, or at the top of the page.

## Review test results

After starting the test, a side panel opens to display test progress in real time.

Snyk API & Web provides feedback on these areas:

* **Connectivity**: Confirms Snyk API & Web can reach the URL
* **WAF Detection**: Alerts you if a firewall can interfere with the DAST scan
* **Authentication**: Validates that credentials successfully grant access to the target
* **Schema Validity**: Verifies the schema provided for API targets
* **Extra Hosts**: Identifies additional domains the web application relies on that you need to add to the target settings

If a check fails or requires further configuration, the side panel provides a call to action to help resolve the issue. You can also review connectivity details and, if applicable, a video of the login attempt.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/configure-targets/test-target-configuration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
