We recommend starting with SoapUI examples - getting them working before you attempt your own implementation. Using SoapUI is very easy:
just install the multiplatform standalone application SoapUI import demo project ws-demo-soapui-project.xml into SoapUI and submit prepared request messages.
The demo project contains DataDelivery and PvPlanner examples preconfigured with #Demo account thus the location is limited to demo region (10x10km)
The REST access examples work out of the box, all that is needed is to just run the requests by clicking on the "Submit" button and you should see successful results of the call. Here is DataDelivery REST access example:
If you were able to get the demo examples working but you are unable to get the requests working with your own API key, then please try recommendations in our our troubleshooting guide.
For adapting the demo requests to your requirements we recommend that you take inspiration from our example request / response documentation (see the next section). It's best if you start from simple request and adapt it to more complicated ones and
that you validate in SoapUI that the request is still working after each incremental change. Detailed explanation of all the parameters in the request can be found in our Solargis API User Guide
