Hello , I Would like to Get Some Help on How to use this Twitch Api
To Get Last 7 days Top Clips For a Special Broadcaster as shown in the example .
It Dosen’t Return anything for me , & i’m not sure if i made a mistake in the Date Format for the proprieties Started_at & ended_at . in my example i did ?started_at=2020-03-01?ended_at=2020-03-08
to get clips between 1 MARS 2020 & 8 MARS 2020 .
Thanks for your help <3 
Your URL is wrong.
It should be
clips?broadcaster_id=foo&started_at=date&ended_at=anotehrdate
Query string arguments need to be & separated in the URL
IT WORKED But i still have a problem with the Date Format ! i don’t know how to convert this date : 2020-03-01 to RFC3339
&started_at=2020-03-01T00:00:00Z&ended_at=2020-03-08T00:00:00Z
Thank Youuu 
iT Worked 
, is there any easy way to use this format in php because in my php script i should be using variables . is there any way to use Varibale like $date.time.now & convert it to this format ?? & substract 7 days from it in the second variable .
https://www.php.net/manual/en/class.datetime.php
Suggests
Y-m-d\TH:i:sP
So
$date = date(‘Y-m-d\TH:i:sP’, time());
$one_week = strtotime(‘-1 week’):
I think i have a problem with First date i should add some more “” i guess , and also the Format Need to be like this 2020-03-08T17:56:03Z i don’t know how to add that letter in the End
eventough i added the P $date = date(“Y-m-d\TH:i:sP”, time()); in the format it give me this !!
Z means you are in UTC
+01:00 means you are in a timezone +1 of UTC
So +01:00 is correct
The P of the timezone in the format means “append the timezone offset”
P Difference to Greenwich time (GMT) with colon between hours and minutes (added in PHP 5.1.3)
You are not URLencoding your parameters
Please stop using screenshots for your code, makes it difficult for me to copy/paste/fix
You can just paste code into the forums, using the relevant formatting functions
$date1 = urlencode(date(‘Y-m-d\TH:i:sP’), time());
$date2 = urlencode(date(‘Y-m-d\TH:i:sP’, strtotime(‘-1 week’));
Am Sorry ,
It Still returning Null For me
<?php
$date1 = date("Y-m-d\TH:i:sP", time());
$date2 = date("Y-m-d\TH:i:sP", strtotime("-7 days"));
$date3 = urldecode($date1);
$date4 = urldecode($date2);
echo $date1;
echo "<br>";
echo $date2;
echo "<br>";
echo $date3;
echo "<br>";
echo $date4;
echo "<br>";
$ch = curl_init('https://api.twitch.tv/helix/clips?broadcaster_id=157527726&started_at=' . $date4 . ' &ended_at= '.$date3);
You need to urlencode. You have urldecoded
$date3 = urlencode($date1);
$date4 = urlencode($date2);
I Changed it , but still NULL
$date1 = date("Y-m-d\TH:i:sP", time());
$date2 = date("Y-m-d\TH:i:sP", strtotime("-7 days"));
$date3 = urlencode($date1);
$date4 = urlencode($date2);
echo $date1;
echo "<br>";
echo $date2;
echo "<br>";
echo $date3;
echo "<br>";
echo $date4;
echo "<br>";
$ch = curl_init('https://api.twitch.tv/helix/clips?broadcaster_id=157527726&started_at=' . $date3 . ' &ended_at= '.$date4);
When i Tried to use the Encoded Date Format in the Api , It Actually Worked
$ch = curl_init('https://api.twitch.tv/helix/clips?broadcaster_id=157527726&started_at=2020-03-01T18%3A42%3A52%2B01%3A00&ended_at=2020-03-08T18%3A42%3A52%2B01%3A00');
However It’s Not working when using Variables like this :
$ch = curl_init('https://api.twitch.tv/helix/clips?broadcaster_id=157527726&started_at=' . $date3 . ' &ended_at= '.$date4);
You have a space before the & of ended_at and after the = of ended_at=
Additionally your dates are back to front
start_at=now&end_at=sevendays_ago
So no results
