Get Google My Business Updates Results by id
My Business Updates API will provide you with the content of posts publicly shared by any business entity on its Google My Business profile.
The returned results are specific to the indicated cid (client ID) or keyword, location and language parameters. We emulate all the parameters with the highest accuracy so that the results you receive will match the actual search results for the specified parameters at the time of task setting. You can always check the returned results accessing the check_url in the Incognito mode to make sure the received data is accurate.
