Apigee Development Framework

A comprehensive framework for Google Apigee API development that provides commonly used policies, shared flows, and best practices for building robust API proxies.

🚀 Features

• 🔒 Security Policies: CORS, OAuth2, API Key validation
• 🚦 Traffic Management: Rate limiting, spike arrest
• 🔄 Data Transformation: JSON/XML conversion
• 📊 Monitoring: Response caching, comprehensive logging
• ⚠️ Error Handling: Standardized error responses
• 🔍 Logging: Audit logging with sensitive data masking
• 📚 Documentation: Complete developer guides and examples
• 🛠️ Tools: Deployment scripts and API proxy templates

🏃‍♂️ Quick Start

1. Clone the framework

   git clone <repository-url>
   cd apigee-framework

2. Deploy shared flows

   ./framework/scripts/deploy-framework.sh -o your-org -e prod -u username -p password

3. Create a new API proxy

   ./framework/scripts/create-api-proxy.sh -n my-api -d "My API" -b /my-api -t https://api.example.com -r resource -o ./my-api

4. Use in your API proxy

   <PreFlow name="PreFlow">
       <Request>
           <Step>
               <Name>security-cors-v1</Name>
               <Condition>request.verb == "OPTIONS"</Condition>
           </Step>
           <Step>
               <Name>authentication-oauth2-v1</Name>
           </Step>
           <Step>
               <Name>logging-audit-v1</Name>
           </Step>
       </Request>
   </PreFlow>
