Technical Documentation

What this API does

The Appwrite Backend API is an open-source backend platform that consolidates essential backend services via a single API. It includes user authentication, real-time databases, scalable cloud storage, and the ability to deploy serverless functions, allowing developers to accelerate application development.

How it works

Developers integrate the API by sending HTTP requests to REST or GraphQL endpoints. Appwrite supports a wide range of programming languages and frameworks, including Flutter and Swift. The API handles tasks such as session management and data synchronization, ensuring a streamlined development experience.

Authentication

The API employs secure user authentication. Developers must implement authentication methods for user access and session management to ensure that data remains secure and accessible only to authenticated users.

Example usage

  • /v1/account/sessions - Create a new session for the authenticated user.
  • /v1/databases/{databaseId}/collections/{collectionId}/documents - Retrieve documents from a specified collection.
  • /v1/functions - Deploy serverless functions for dynamic application features.
  • /v1/storage/files/{fileId} - Upload files to Appwrite's storage.

Limits

The API has a free Cloud plan that supports up to 75,000 Monthly Active Users (MAUs). For detailed rate limits, refer to the official documentation.

Ideal use cases

  • Developing mobile applications with integrated backend services.
  • Constructing web applications requiring real-time data synchronization.
  • Building serverless applications deploying dynamic functions.
  • Implementing custom authentication systems for enhanced user security.

Examples

Real-World Applications
