Before you can use the API, you will need to set up an APIs Console project, create a client ID and its Secret Key.
To Access APIs you should have below mantioned Variable Values:
Copy below index.php
<?php
$ch = curl_init();
$clientId = '8461_SOMETHING_LIKE_THIS_pb.apps.googleusercontent.com';
$clientSecret='ar_SOMETHING_LIKE_THIS_K';
$redirectUri='http://_SOMETHING_LIKE_THIS_/index.php';
$refreshToken='1/Lzc5Xm_SOMETHING_LIKE_THIS_wBhrrY7qfywIr-3e';
$appid='com.SOMETHING_LIKE_THIS.google';
$productID='google.monthly.sub001';
$purchaseToken='cgojkfejbmfjhjiciphjkijd.AS-J__SOMETHING_LIKE_THIS__eLaFlpW_ita2B-5__SOMETHING_LIKE_THIS__3XmJIQ';
$TOKEN_URL = "https://accounts.google.com/o/oauth2/token";
$VALIDATE_URL = "https://www.googleapis.com/androidpublisher/v2/applications/".
$appid."/purchases/subscriptions/".
$productID."/tokens/".$purchaseToken;
$input_fields = 'refresh_token='.$refreshToken.
'&client_secret='.$clientSecret.
'&client_id='.$clientId.
'&redirect_uri='.$redirectUri.
'&grant_type=refresh_token';
//Request to google oauth for authentication
curl_setopt($ch, CURLOPT_URL, $TOKEN_URL);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $input_fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$result = json_decode($result, true);
if (!$result || !$result["access_token"]) {
//error
return;
}
//request to play store with the access token from the authentication request
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$VALIDATE_URL."?access_token=".$result["access_token"]);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);
$result1 = curl_exec($ch);
$result1 = json_decode($result1, true);
//print_r($result1);
if (!$result1 || $result1["error"] != null) {
//error
return;
}
print_r($result1);
?>
CREATE REFRESH TOKEN
If you already created refresh token it will be not visible to you AGAIN. you have to create new one for new Refresh Token.
To Create Refresh token you need Access token first for that you have to hit below Url with your CLIENT_ID and REDIRECT_URL
https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/androidpublisher&response_type=code&access_type=offline&redirect_uri=...&client_id=...
Copy code variable from Url ACCESS_TOKEN (code)
Now you have your access_token (code)
Hit token URL with Post method
https://accounts.google.com/o/oauth2/token
and pass varibles in body
"grant_type":"authorization_code" //Keep it same
"code":"4/AAAHZKZbq_ACCESS_TOKEN_PASTE_HERE_D1x_1B3rJ0#" //change it with your Details
"client_id":"YOUR CLIENTID HERE" //change it with your Details
"client_secret":"YOUR SECRET KEY HERE" //change it with your Details
"redirect_uri":"YOUR REDIRECT URL" //change it with your Details
you should get response {
"access_token": "ya29.G**************COy-QF1w7-Ei****jDw_c1_g****jrQ8s4******3GACNXf1le",
"expires_in": 3600,
"refresh_token": "1/HJA____THIS IS REFRESH TOKEN______ GJh8U",
"token_type": "Bearer"
}
