Retrofit + Jetpack Compose — API Communication Patterns

Integrate Retrofit with Jetpack Compose for robust network operations. Retrofit API Interface Define suspend functions for async operations: interface UserApi { @GET ( "users/{id}" ) suspend fun getUser ( @Path ( "id" ) userId : String ): User @POST ( "users" ) suspend fun createUser ( @Body user : User ): User @DELETE ( "users/{id}" ) suspend fun deleteUser ( @Path ( "id" ) userId : String ) } Retrofit Builder with OkHttp Configure Retrofit with interceptors: val okHttpClient = OkHttpClient . Builder () . addInterceptor { chain -> val request = chain . request () . newBuilder () . addHeader ( "Authorization" , "Bearer $token" ) . build () chain . proceed ( request ) } . addInterceptor ( HttpLoggingInterceptor (). setLevel ( BODY )) . build () val retrofit = Retrofit . Builder () . baseUrl ( "https://api.example.com/" ) . client ( okHttpClient ) . addConverterFactory ( GsonConverterFactory . create ()) . build () . create ( UserApi :: class . java ) Safe API Call Error Handling Wrap AP
