custom app external api response not working HSNM Front-end Welcome Portal general discussion about HTML, CSS, layout, custom apps, templates

[miami1983]

Hi ,
we build custom app to integrate with API server for : user need to enter his mobile number , the API server will get the user response , check his balance and recharge his hsnm user

but using the API url inside the custom app , not provide us the response as normal using in browser

the error we observe :
from origin 'http://wifi.ps' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'.

after set no-cors in the custom app .. the API integration working and recieve transaction to external server , but without response

method: 'GET',
cache: 'no-cache',
mode: 'no-cors',

and the response are : "failed to load response data : NO data found for given resource with given identifier "

how we can solve it while we try all things :

Hi
If calling the API through a web browser it works but it didn't work on your APP, it means that there was something wrong on your APP
In addition to that, the error your provided (".... 'http://wifi.ps' has been blocked by CORS policy: Response to preflight request doesn't pass access control check:....") is not an error provided by our system

Best regards

but when inspect the result over HSNM hotspot portal login for custom app , its detect the response from console as 0 all the time

I use php API server with the same error .. i can't read the response in the console it give me "null" in the body

so we need help

[HSNMSupport]

The problem has been solved.
This issue was caused by a wrong configuration of the server hosting the API called.
They added the right CORS policy and the remote call from the HSNM app started working.
