Import of messages

To import messages from a file, use the command exchange/import_messages:

svc=exchange/import_messages&params={"itemId":<long>,
				     "eventHash":<text>}

Current request can't be executed simultaneously with any request from this chapter and following requests:

• report/exec_report,
• report/export_result,
• report/get_result_chart,
• report/get_result_map,
• messages/load_interval,
• render/create_messages_layer,
• unit/get_trips,
• resource/get_driver_bindings,
• resource/get_trailer_bindings,
• account/get_account_history.

To load a file, use a POST request with multiple contents (multipart/form-data).

For example:

Request URL: https://hst-api.wialon.com/wialon/ajax.html?svc=exchange/import_messages&sid=8157df114c0e601f0f31091c3c2ac53d
