Your description is a little vague. Are you talking about send-as alias accounts or alternate email accounts?

Send-as Alias

Either way, you can interact with the send-as accounts here: Manage Send-as Alias

Alternate Emails via Admin SDK

• As for alternate email accounts, they can be accessed via:
  • Admin SDK: https://developers.google.com/admin-sdk/directory/v1/guides/manage-user-aliases?hl=en
  • Google Apps Script: https://developers.google.com/apps-script/reference/gmail/gmail-app#getAliases()
• Additional info here on how the accounts work.
  • Email addresses associated with your account
  • Alternate email addresses and other Google products
  • Connect other email accounts to your Google Account

Federated Login

Also, I'm not exactly sure how you are trying to incorporate this functionality into your site but another area I recommend checking out is Federated Login for Google Account Users. This might also provide you with the functionality you seek.

Using federated login (also known as federated identity), your website or application can allow visitors to sign in using their Google user accounts. Federated login frees users from having to set up separate login accounts for different websites, and frees you from the task of implementing login authentication measures.
