In the Prestashop backend I activated the webservice and I created an authentication key. Testing in browser works well but now I want to access the webservice via JavaScrip
Finally, I figured out how to send the ws_key:
$http({
method: 'get',
url: ws_url + 'customers/?schema=blank',
params: {
ws_key: ws_key
});
You have to pass the ws_key param with your key to access the PrestaShop webservice.
Although i am not php guy and i haven not used prestashop ever, but may be you forgot provide access in your crodova application this might be the issue please add
<access origin="*"/>
this to your config.xml file hopefully it will work thanks, please do not forgot mark as an answer if it helps you..
