If you have an embeddable code, you can add new features in your clients' websites. Here are the instructions:
1. Go to www.reseller.pagevamp.com and login to your reseller account.
2. Go to Clients tab. Then, select the settings cogwheel of the client for whom you want to add the code.
3. Click on Embed Code. Then, enter your code and click Update.
4. Finally, login to the client's account and click on Publish at the top-right corner.
Once that's done, your code will be added to the website's Head tag, and the functionality will be activated in the client's website.
