set_relationship returns 500 in v7.11. Is backward compatibility not supported?

Question

My use case is simple. I'm creating a Contact, I'm creating a Case and I associate that Case with the contact. When we initially built the integration, only api v4_1 was available.

When use API Key of SugarCRM v7.11, Contact creation and Case creation are succeeding. However, when the method `set_relationship` is invoked, the SugarCRM server is returning a 500.

The same code works for v6.5

How do you suggest we alter the integration to support all versions of SugarCRM for our use case?

Hi Arjun Mayilvaganan , SugarCRM last released new code (not counting defect fixes) for v4.1 at the end of 2012. All new development efforts in the years since have focused on v10 and v11. I recommend making the switch. That being said, this v4.1 endpoint worked fine for me on a SugarCRM-hosted 7.11.1.0 Enterprise instance on PHP 7.1.14 I used these two documents as guides: http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.11/Integration/Web_Services/v1_-_v4.1/… and http://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_7.11/Integration/Web_Services/v1_-_v4.1/… Here is my code: / service / v4_1 / rest . php" ; $username = " < username > " ; $password = " < password > " ; //function to make cURL request function call ( $method , $parameters , $url ) { ob_start ( ) ; $curl_request = curl_init ( ) ; curl_setopt ( $curl_request , CURLOPT_URL , $url ) ; curl_setopt ( $curl_request , CURLOPT_POST , 1 ) ; curl_setopt ( $curl_request , CURLOPT_HTTP_VERSION , CURL_HTTP_VERSION_1_0 ) ; curl_setopt ( $curl_request , CURLOPT_HEADER , 1 ) ; curl_setopt ( $curl_request , CURLOPT_SSL_VERIFYPEER , 0 ) ; curl_setopt ( $curl_request , CURLOPT_RETURNTRANSFER , 1 ) ; curl_setopt ( $curl_request , CURLOPT_FOLLOWLOCATION , 0 ) ; $jsonEncodedData = json_encode ( $parameters ) ; $post = array ( "method" = > $method , "input_type" = > "JSON" , "response_type" = > "JSON" , "rest_data" = > $jsonEncodedData ) ; curl_setopt ( $curl_request , CURLOPT_POSTFIELDS , $post ) ; $result = curl_exec ( $curl_request ) ; curl_close ( $curl_request ) ; $result = explode ( " " , $result , 2 ) ; $response = json_decode ( $result [ 1 ] ) ; ob_end_flush ( ) ; return $response ; } //login ---------------------------------------------- $login_parameters = array ( "user_auth" = > array ( "user_name" = > $username , "password" = > md5 ( $password ) , "version" = > "1" ) , "application_name" = > "RestTest" , "name_value_list" = > array ( ) , ) ; $login_result = call ( "login" , $login_parameters , $url ) ; / * echo " < pre > " ; print_r ( $login_result ) ; echo " " ; * / //get session id $session_id = $login_result - > id ; //relate -------------------------------------------- $relationshipParams = array ( //session id 'session' = > $session_id , //The name of the module.
