There are some peculiarities in working with reports. All commands from the chapter Reports except report/update_report can be performed only if the session contains some results of report execution. A session can contain only one report at the same time. That's why before executing a new report, you need to clear results of the previous one by the command report/cleanup_result.
For executing report the request exec_report is used:
<your_wialon_pro_address>/ajax.html?svc=report/exec_report& params={ "reportResourceId":163266, "reportTemplateId":10, "reportObjectId":34868, "reportObjectSecId":0, "interval":{ "from":1356984000, "to":1358711999, "flags":0 } }&sid=<your_sid>

Conclusions that can be drawn out of the response:
To get data from tables you should use request report/get_result_rows. It is suitable for most reports. However, it returns only rows of the top level. If you have a multilevel report, you need to make an additional request to get the rows of lower levels – report/get_result_subrows.
Let's get the first row of the table which has index 0 in “tables” array.
<your_wialon_pro_address>/ajax.html?svc=report/get_result_rows& params={ "tableIndex":0, "indexFrom":0, "indexTo":0 }&sid=<your_sid>
Response:
[{ "n": 0, "i1": 108, "i2": 214, "t1": 1357047418, "t2": 1357056357, "d": 3, "c": ["1", "2013-01-01", { "t": "17:36:58", "y": 53.9097984, "x": 27.4998528 }, { "t": "Берута ул., Минск", "y": 53.9097984, "x": 27.4998528 }, { "t": "20:05:57", "y": 53.8847872, "x": 27.5675072 }, { "t": "Маяковского ул., Минск", "y": 53.8847872, "x": 27.5675072 }, "", "0:11:15", "0:00:00", "0.00 км", "0.00 км", "0 км\/ч", { "t": "72 км\/ч", "y": 53.9070656, "x": 27.5216608 }, "3", "0 л", "0 л"] }]
Number 3 in the parameter d tells us that the current row contains 3 subrows. To get them, make the request:
<your_wialon_pro_address>/ajax.html?svc=report/get_result_subrows& params={ "tableIndex":0, "rowIndex":0 }&sid=<your_sid>
Response:

During execution of the report a layer with trips and parkings was generated for the report. We can get the image of this layer (combined with map) using the request get_result_map:
<your_wialon_pro_address>/ajax.html?svc=report/get_result_map& params={ "width":600, "height":600 }&sid=<your_sid>
Response:
Also there is “Speed and mileage chart” in the report. You can get its image using the request get_result_chart. To place a chart name above the chart, set the flag 0×01, and to place a legend under the chart, set the flag 0x200.
<your_wialon_pro_address>/ajax.html?svc=report/get_result_chart& params={ "attachmentIndex":0, "action":0, "width":600, "height":300, "autoScaleY":0, "pixelFrom":0, "pixelTo":300, "flags":513 }&sid=<your_sid>
