create_shared_link_with_settings responding conflict 409

[bhuwan]

Hi, 

create_shared_link_with_settings responding 409 conflict error but it is passing data in exception. So I try to this

$client = new Client();
$parameters = [
    "path"  => "id:".$imageId,
];
$url = '';
try{
    $response = $client->request('POST', 'https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings',
        [
            'headers'=>
                [
                    'Authorization'=>'Bearer '.$acc_token,
                    'Content-Type'  => 'application/json',
                ],
            'body'=>json_encode($parameters)
        ]);
}catch(ClientException $exception){
  $url = json_decode($exception->getResponse()->getBody(), true)['error']['shared_link_already_exists']['metadata']['url'];
}
return $url;

When I catch exception I am able to get the URL as needed. Please advise me how I can avoid conflict error.

The /2/sharing/create_shared_link_with_settings endpoint will always return a 'shared_link_already_exists' error if a shared link for the requested item already exists. Catching and handling the exception is the proper way to accommodate that. (Note that there are other possible error types as well. You can find them listed in the documentation.)

If you want to avoid that though, you can first call /2/sharing/list_shared_links to check for an existing link. (You'll probably want to use 'direct_only:true' in this case.)
