  • JSON/XML: Data is typically exchanged in lightweight formats like JSON or XML.

GraphQL

GraphQL is an alternative to REST that offers more flexibility and efficiency:

  • Flexible Queries: Clients can request exactly the data they need, reducing over-fetching and under-fetching of data.
  • Single Endpoint: All requests are made to a single endpoint, simplifying API management.

Third-Party Services

Integrating third-party services can add valuable functionality to your app:

  • Payment Gateways: Services like Stripe, PayPal, and Square enable secure and efficient payment processing.
  • Social Media Logins: Integrating login options from platforms like Facebook, Google, and Twitter can streamline user authentication.
  • Analytics: Tools like Google Analytics and Firebase Analytics provide insights into user behavior and app performance.
