To use the S3zipper API, the first thing we will need to get is a user token. Tokens carry user-specific information and make it simple for users to access certain resources securely. Instead of needing to provide a user-name and password, a user only needs to provide a server generated token to perform transactions.

For this, we will need to create a user account. Next step is to get userkey and usersecret under /developer section. Follow the link below.
Create account or login

Once you have the user key and user secret, you can now go ahead and get a token.

The example below uses Go(Golang) and Echo web framework.

To see other examples in other languages visit API documentation.
