Hi I am integrating rest suitetalk with python So I want create login and forget password functionality by calling netsuite api How can I do that ?

There are a number of ways to do it. I have a few external systems (customer and sales portals, for example), that integrate with NetSuite. For the customer portals, I've setup custom entity fields in NetSuite to store the username and password that has been assigned to a customer. The custom Web app makes a SuiteTalk REST call, or a call to a RESTlet, to handle the authentication. I hope that helps. Good luck!

Thanks. As I'm new to netsuite, can you help me to know how you authenticate your customers using netsuite API's. Basically I want to know how you've build the authentication system.
