How it works
Integrate with your website
Create an account to get your API key and download one of our code libraries to get a quick start.
2. Get Permission
Your users controls who can access their contacts
We’ll give you a custom URL for each user that walks them through the authentication process.
“Please Wait” while we download the address book
You can monitor our progress while we download the contacts and present your user with a progress indicator, spinning beach ball, pinwheel or whatever your designers prefer.
Grab it while you can, we’re only going to keep it in memory for a few minutes
You can get it in XML or JSON format, whatever is most convenient for your application.
