Mobile API Best Practices
Mobile API Goals
• Reduce Network Calls
• Small Responses with Just Enough Data
• Secure
Caching
• Cache-Control Headers
• Set no-cache and max-age as appropriate
• Set to no-cache on Errors
• Images
• GET and HEAD request headers
• Content-Length
• Content-Type
• Last-Modified
JSON
• Compact
• Low memory footprint
• 2x faster to parse than XML
• Easier to create on device
• Smaller Request Bodies
REST-like
• Resource Endpoints
• Plural Endpoints should return object summaries
• Single Resource Endpoints return full object
• Can return object summaries of related objects
• Action Endpoints
• Perform complex service actions atomically
Security
• HTTPS
• No secure data in URL Query
• OAuth 2
• Token-based
• Authorization Headers
• HMAC for request authentication
Recommended
