Hello all,

I'm having problems generating the access token from refresh token when using the generateAccessTokenFromRefreshToken function.

Firstly, I'm using CURL to receive both the access_token and refresh_tokens. Maybe this is where I am going wrong, as the access token is already successfully created?

If anyone could help, that would be great. Please see code below:

2.   $curl = curl_init();
3. 
   
4.   curl_setopt_array($curl, array(
5.     CURLOPT_URL => "https://accounts.zoho.eu/oauth/v2/token?client_id=" . $clientId . "&client_secret=" . $clientSecret . "&redirect_uri=" . $redirectUri . "&code=" . $grantToken . "&grant_type=authorization_code",
6.     CURLOPT_RETURNTRANSFER => true,
7.     CURLOPT_ENCODING => "",
8.     CURLOPT_MAXREDIRS => 10,
9.     CURLOPT_TIMEOUT => 30,
10.     CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
11.     CURLOPT_CUSTOMREQUEST => "POST",
12.     CURLOPT_HTTPHEADER => array(
13.       "Accept: */*",
14.       "Accept-Encoding: gzip, deflate",
15.       "Cache-Control: no-cache",
16.       "Connection: keep-alive",
17.       "Content-Length: ",
18.       "Cookie: a5581ceb1f=0f0996ff9f95d2f31a5b3a5b981d1903; iamcsr=046c84ea-a41e-4a60-9542-701f04a748ce",

21.       "User-Agent: PostmanRuntime/7.15.2",
22.       "cache-control: no-cache"
23.     ),
24.   ));
25. 
    
26.   $response = curl_exec($curl);
27.   $err = curl_error($curl);
28. 
    
29.   curl_close($curl);
30. 
    
31.   if ($err) {
32.     echo $error;
33.     return;
34.   }
35. 
    
36.   $decodedResponse = json_decode($response, true);
37. 
    
38.   if (array_key_exists("error", $decodedResponse)) {
39.     echo $decodedResponse["error"];
40.     return;
41.   }
42. 
    
43.   if (!array_key_exists("access_token", $decodedResponse) ||
44.       !array_key_exists("refresh_token", $decodedResponse)) {
45.     echo "No access_token or refresh_token";
46.     return;
47.   }
48. 
    
49.   $accessToken = $decodedResponse["access_token"];
50.   $refreshToken = $decodedResponse["refresh_token"];
51. 
    
52.   echo $accessToken;
53.   echo "<br>";
54.   echo $refreshToken;
55. 
    
56.   $configuration = array(
57.     "client_id"=> $clientId,
58.     "client_secret"=> $clientSecret,
59.     "redirect_uri" => $redirectUri,
60.     "currentUserEmail"=> "zoho.developer1@infarm.com",
61.     "accounts_url" => "https://accounts.zoho.eu"
62.   );
63. 
    
64.   ZCRMRestClient::initialize($configuration);
65.   $oAuthClient = ZohoOAuth::getClientInstance();
66.   $userIdentifier = "zoho.developer1@infarm.com";
67.   $oAuthTokens = $oAuthClient->generateAccessTokenFromRefreshToken($refreshToken, $userIdentifier);
68.   var_dump($oAuthTokens);
69. 
    
70.   $rest = ZCRMRestClient::getInstance();
71.   $orgIns = $rest->getOrganizationDetails()->getData();
