Xamarin.Forms, ASP.NET Core, Web API -- 2

Job ID: 34369905

Budget: $30 – $250 USD

Hello.
I have an Android & UWP ordering app developed with Xamarin.Forms
This data exchange uses the conventional XML Web service (SOAP).
Since the amount of data is large with XML, convert the API to JSON
I would like to improve.

This may be helpful.

as a sense of volume
The existing API has 25 methods (many are unused)

Basically, the smartphone app side calls the API at startup
Because the data is cached in the app
Approximately the number of methods = the number of calls.

Request items are changes on the API side, changes on the calling side Xamarin
to development and testing


If you have experience with Xamarin and XML web services, contact me.
