#### Lesson text

# API Architecture and Authentication

This module gives you the decision framework for choosing the right API surface, runtime boundary, and authentication strategy before you write implementation code.

## Why This Module Matters

API mistakes in Contentstack are rarely syntax problems. They are boundary problems: wrong plane, wrong token, wrong runtime, or wrong assumption about ownership.

## You Will Be Able To

*   distinguish delivery, preview, and management responsibilities clearly
*   choose between REST and GraphQL based on use case rather than trend
*   apply safer authentication and credential-scoping practices

## Recommended Preparation

Complete Courses 1 and 2 first, then begin Course 3 when you are ready to connect concepts to code.

## Estimated Effort

75-90 minutes

## Practice Focus

Use the Veda storefront to map which services read published content, which services need privileged write access, and which credentials belong where.

## Suggested Next Step

Start with lesson 1 in this module and trace every example back to a concrete runtime or ownership boundary.

#### Key takeaways

- Connect **API Architecture and Authentication : Overview** back to your stack configuration before moving to the next module.
- Capture one concrete artifact (screenshot, Postman call, or code snippet) that proves the step works in your environment.
- Re-read the delivery versus management boundary for anything you changed in the entry model.
