Hello Paolo,

You say that the above don't work, but, do you get some error message? Please, try the app by opening it in Firefox, and, press the F12 key in order to open the developer console. Then, take a look at the request, and, if you can see any error or something that we can use to find a possible solution.

Hi,

this is the error log:

Failed to load http://xxxxxx:1880/recuperopassword?email=xxxxx@gmail.com&password=1: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:9999' is therefore not allowed access.

for me is how if the header is not passed..

Hello Paolo,

If I am not wrong, the problem is related with the CORS permissions. Maybe the thirdparty server don't allows HTTP calls from client apps. If this is the problem (and I think so) you must prepare your own bridge in your own app's server. Then your app communicate with your server (who provide the right CORS permissions) and your server is responsible to communicate with the thirdparty API and provide you the right response.

You can take a look at various AB samples like SimplePost, HttpClient, etc. Take a look at the included PHP script in the samples. As you can see, that scripts setup the right CORS permissions, to allows the app to communicate with the server / scripts without problems.
