# Reusable Auth & Header Configurations

> Create reusable scan profiles with consistent headers like Authorization and API keys for authenticated, repeatable API testing.

## Overview

Reusable Auth & Header Configurations allow teams to define consistent authentication and header profiles for API security testing.\
Whether you’re working with Authorization tokens, API keys, session headers, or custom metadata, these profiles ensure every scan is authenticated correctly and executed with the right request context.

## Key Capabilities

> **Reusable Header Profiles**
>
> Create reusable header sets that can be applied across scans, collections, and environments.

> **Authentication Support**
>
> Add Authorization tokens, API keys, Bearer tokens, and custom auth mechanisms for consistent request execution.

> **Environment-Specific Overrides**
>
> Automatically match header profiles with environment-specific values for Dev, Test, QA, or Sandbox.

> **Reduce Manual Effort**
>
> Eliminate repetitive header setup across multiple scans or collections.

> **Improved Testing Accuracy**
>
> Ensure all API security tests run with valid headers, reducing false negatives and authentication errors.

> **Works Across All Scan Types**
>
> Apply header configurations to automated scans, manual requests, or rule-based executions seamlessly.

## Value

Standardize your API security testing with consistent, reusable authentication and header configurations.\
This ensures accuracy, reduces setup time, and prevents authentication-related scan failures across all environments and projects.
