This API is used to retrieve all reports of your message transmissions (delivery, hard/soft bounces, open and click events) from our database.

The API works on eventLogIDs which is a mandatory parameter to be passed by the calling client. eventLogID parameter has to be zero when calling this API for the first time. When responses are retrieved, the calling client is expected to parse the value of the last eventLogID from the response, store it and increment it by one to ensure that it gets the latest batch of responses next time.
