Most mobile apps that integrate with WordPress focus on content consumption — reading blog posts, browsing categories, or viewing pages. But what if you want to enable users to contribute content, like submitting articles or publishing posts directly from a Flutter app?

Whether you’re building a blogging app, a multi-author publishing platform, or a custom CMS experience, Flutter + WordPress can make it happen — securely and efficiently. The key is using authenticated POST requests via the WordPress REST API.

What This Workflow Enables

• Users can write and submit articles directly from your Flutter app.

• Only logged-in users can create or edit posts.

• You control post status (e.g., draft, pending, published).

• You can associate posts with categories, tags, or custom fields.

Why Use the REST API for Article Submission?

WordPress exposes a powerful REST API that allows external clients (like a Flutter app) to interact with posts, users, media, and more — all through simple HTTP requests. To submit content:

• You send a POST request to the /wp-json/wp/v2/posts endpoint.

• The request must include valid authentication headers.

• The body includes the post content: title, body, categories, etc.

Step-by-Step Workflow (Conceptual)

1. User Logs In

The app captures login credentials and sends them to the WordPress backend for authentication — typically via JWT (JSON Web Tokens) or application passwords.

2. Receive Auth Token

Upon successful login, the backend returns a token. This token is saved securely in the app and added to the headers of all future requests.

3. User Composes a Post

The user fills out a form with:

• Title

• Content (HTML or plain text)

• Categories or tags

• Optional media (images)

4. Submit the Post

The Flutter app sends a POST request to /wp-json/wp/v2/posts, including:

• Authorization: Bearer <token> header

• A body containing post data

5. Post Handling

The WordPress site creates the post under the authenticated user’s ID and returns a success or error message.

Authentication Methods (High-Level)

JWT Authentication

• Secure and scalable

• Requires WordPress JWT plugin (e.g., JWT Auth for WP REST API)

• Token must be passed with every request

Application Passwords (for WordPress.com / Jetpack sites)

• Easier setup, limited scope

• Supported by REST API natively

• More suitable for personal or low-risk apps

Important: Authentication is required for post creation. Anonymous users cannot use this endpoint unless explicitly allowed (not recommended for public apps).
