Basic Authorization Support



My Client is using this application manually. I want to integrated this application into our site. We are planning to implements Basic Authorizationion Support. Not for Oauth because of every time needs to login and access this constanct Contact. Could you please give me sample code for Basic Authorization Support? We are using .NET c# technology.


With Regards



Hi Sakthi,

For your application you will still want to use OAuth as it is the most secure method for connecting with the account.  However, when they login you will receive an OAuth token via the callback/ redirect uri that you can store and continuously use for that account (this means that once you receive the token they will not need to log back in again).

You can find out more about authentification here:


And get the SDK/ see code examples here:

Hopefully this helps!

If you have any other questions please feel free to let me know.

Have a great day,
