Instagram basic display api withlaravel - laravel-8

Question

I'm working on Instagram basic api, in my project user can connect their Instagram feed to our project. For that I'm generating a short live authentication code but could not get the long live access code. Its returning null.
Here is my code for getting long live access code.
$client_secret = "###############";
$client_id = "###############";
$redirect_uri = '#########';
$short_access_token = "####"; // getting this from another function
$ig_rtu = 'https://api.instagram.com/oauth/access_token?client_id='.$client_id.'&client_secret='.$client_secret.'&grant_type=authorization_code&redirect_uri='.$redirect_uri.'&access_token='.$short_access_token;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $ig_rtu);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$ig_new = curl_exec($ch);
curl_close ($ch);
return $ig_new = json_decode($ig_new, true);
In postman this works fine but I could not get it done in Laravel.
What I'm missing here ?
Any lead is appreciated.

Answer 1

I've done this in 3 steps. I will leave the code out for step 1 and include my implementation for step 2 and 3.
Steps:
get the code
get the short lived token using the code
get the long lived token using the short lived token
Here are the public variables used.
public $appId = null;
public $appSecret = null;
public $redirectUrl = null;
// Instagram request data
public $socialUserId = null;
public $socialAuthCode = null;
public $socialUserName = null;
public $socialShortAccessToken = null; // 1 hour
public $socialLongAccessToken = null; // 60 days
public $socialLongAccessTokenExpiresInSeconds = null; // 5183910 seconds || 59.99896 days - relative to date created
Step 2:
public function getUserIdAndShortAccessToken(){
/* Get UserId and access Token
https://api.instagram.com/oauth/access_token \
-F client_id={app-id} \
-F client_secret={app-secret} \
-F grant_type=authorization_code \
-F redirect_uri={redirect-uri} \
-F code={code}
*/
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,
'https://api.instagram.com/oauth/access_token');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
$post = array(
'client_id' => $this->appId,
'client_secret' => $this->appSecret,
'grant_type' => 'authorization_code',
'redirect_uri' => $this->redirectUrl,
'code' => $this->socialAuthCode,
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$curlResult = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
curl_close($ch);
return;
}else{
curl_close($ch);
}
$this->socialUserId = json_decode($curlResult)->user_id;
$this->socialShortAccessToken = json_decode($curlResult)->access_token;
}
Step 3:
public function getLongAccessToken(){
/* Get long-lived token
curl -i -X GET "https://graph.instagram.com/access_token
?grant_type=ig_exchange_token
&client_secret={instagram-app-secret}
&access_token={short-lived-access-token}"
*/
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'https://graph.instagram.com/access_token?grant_type=ig_exchange_token&client_secret='
.$this->appSecret.'&access_token='
.$this->socialShortAccessToken
);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curlResult = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
curl_close($ch);
return;
}else{
curl_close($ch);
}
$this->socialLongAccessToken = json_decode($curlResult)->access_token;
$this->socialLongAccessTokenExpiresInSecond = json_decode($curlResult)->expires_in;
}
