The first thing you need for a third party integration is an API Key.

You can access the API Key for the companies you manage from the API Key section under Settings.

To navigate to the API Key section, go to the Account Settings by clicking on your name (alias) on the top right hand side of the Outgrow Dashboard interface. Now, select Settings from the drop-down menu. On the Settings page you'll find the API Key option on the left sidebar.

Click on the Generate/Regenerate option to get the API key for the company you want to add to Zapier for integration. Once the API key is generated you can copy it directly using the Copy option.
