Get steps from the Google Fit API using PHP

Build an integration towards the Google Fit API using PHP showing the number of steps for the last 7 days. This project contains of 4 tasks: - Implement the google-api-php-client ([login to view URL]) - put the number of steps for the last 7 days starting from current day into an array: $steps[0] (current day) to $steps[6] (6 days ago) - show the timestamp (epoch) for the last retrieved activity from Google Fit (usually 0 to 5 hours). Se example below. (This is used to show how long ago the google fit app was synced) - once the access token has expired (after 1 hour) and the page is reloaded, it shold refresh the token without any new consent from the user. This should be a single PHP page. On the page it should be: - a link/button to authenticate to the Google Oauth (standard oauth process) - print the array of steps like: "Today: $steps[0]<br/> 1 day ago: $steps[1]" and so on... - print the epoch timestamp for current day, like: "Timestamp: 1601037000633948165" The page does not have to look pretty, just text is fine. It's preffered to run this in PHP 5.6, if this caused some problems it can run in PHP 7.x instead. More info about the REST API: [login to view URL] More info about the oauth process: [login to view URL] More info about reading the daily steps: [login to view URL] Attached is examples from the Google API playground of the POST request and the response. Here are also some explainations: POST request: This is used to set timestamp for start (7 days ago) and current day. "startTimeMillis": 1600639200000, "endTimeMillis": 1601244000000 POST response: Number of steps: "intVal": 1841 Timestamp for last activity (to be printed on the page for current day): "endTimeNanos": "1600712516394036541",
