To be honest, REST is just a way that sets up an interaction in complex ways without the client knowing anything beforehand about the server and the resources it hosts. You define that the transmission is going to be HTTP and then follow the rules for it.
Now your call to the API can be done from a web browser, an app on a phone or a tablet.
here is something I wrote to get data for ExchangeRates. apicall.Clear(); // This is a string to hold the params for the call I am making for data
apicall.Append("api/historical/" + EOM);
apicall.Append(".json?app_id=bbfaf8b299c54f93811b2144f9d33c3e&symbols=GBP,EUR,CAD"); // get the dates for use in the string HttpResponseMessage httpResponseMessage = await client.GetAsync(apicall.ToString()); HttpResponseMessage response = httpResponseMessage; if (response.IsSuccessStatusCode) { // put the data returend into a data object I have local. eRateReturn rate = await response.Content.ReadAsAsync<eRateReturn>();
Here is eRateReturn class(s) for data: public class Rates { public float GBP { get; set; } public float CAD { get; set; } public float USD { get; set; } public float EUR { get; set; } }
public class eRateReturn { public float timestamp { get; set; } public string Base { get; set; } public DateTime date { get; set; } public Rates rates {get; set;} }

Thanks for the reply Russell, I have now discovered this particular thing also supports REST api, just trying to figure out oAuth

Too bad that Alan is no longer among us, he redid his application all in Web Service calls years ago.
In general, the "service" is a replacement for a data store. You ask for data from the service and it gives it to you in SOAP, xml that is. What you actually receive is some sort of collection of data, that may have collections within it. You could do the same thing in arrays if you wanted in VFP.
Now the data is yours to use at your desire. You may have to package the data back into XML that mimics the data they sent you for inserts, updates, maybe even deletes. Now through the "service" you post that XML pack to them.
Today the industry is changing the name from Web Service to API but in general it works in much the same way.

Is anyone able to share an example of working with a webservice purely in code?
Thanks
