Hunter offers a free Pipedrive integration that connects to your Pipedrive account to automatically export newly generated leads.
To get started simply go to the "Leads" section of your account.
In the left sidebar, find the Connected Apps section and click on the + New application button.

Select Pipedrive.
Enter your Pipedrive API key in the text box. You’ll find your personal API token in the API inside the Settings->Personal->API section of Pipedrive.

Now you’ll see Pipedrive in the “Connected Apps” section.
Add new leads to your list.
Log in to your Pipedrive account and select the People section inside Contacts. There you’ll see all the leads previously created on Hunter.

Please note: Hunter will automatically save to Pipedrive both newly generated leads and leads already saved in Hunter before launching the integration.
