I'm trying to retrieve data from fitbit with my website but facing problems with getting the access token and other staff.
The first page is named test1.php which contains this code:
<?php
header('Location:https://www.fitbit.com/oauth2/authorize?response_type=code&client_id=XXXXXX&redirect_uri=https%3A%2F%2Fexample.com%2Ftest2.php&scope=activity%20heartrate%20location%20nutrition%20profile%20settings%20sleep%20social%20weight&expires_in=604800');
exit;
?>
So, from the page "test1.php", I'm redirected to the authorization page of fitbit. There I can select the scope I want to share and then click "Allow". Then I'm redirected to the page www.example.com/test2.php which is my redirect_uri link.
From this stage, I can not do the codes. I have tried several codes but couln't succeed. I need help with this.
I found this in the website. How to do this with PHP? I mean what should I write in my test2.php page to get the access token? And what should I do further to get all data I want?
POST <a href="https://api.fitbit.com/oauth2/token" target="_blank">https://api.fitbit.com/oauth2/token</a>
