Getting advice
1

Using REST API unable to create user it shows CORS error

keycloak version : 20.0.3

URL : http://localhost:8080/admin/realms/dev-auth/users
Method : Post
Headers: {
‘Authorization’ : Bearer ${token},
‘Content-Type’: ‘application/json’,
}
This is working fine in Postman

While calling this api from frontend application like React, Angular or Vue it shows CORS issue
