  2. Search for and select ConvertKit from the dropdown field.
  3. Log into your ConvertKit dashboard to obtain your API Key. To do this:
    1. In your ConvertKit dashboard, click on your account’s name in the top right corner, then select Account settings from the dropdown menu that appears.
    2. Copy the API Key shown partway down the Advanced screen.
      Find your ConvertKit API Key
  4. Return to the OptinMonster Integration View to paste your API Key in the corresponding field. Also create a ConvertKit Account Label (for internal use only).
  5. Click Connect to ConvertKit.

  6. Once your ConvertKit account is connected, select the “Email Provider Form” you would like to send the leads from this campaign to.
  7. When you are finished, click Save.

I’ve connected my integration and new leads are being added to my list, but OptinMonster shows 0 conversions for my campaign. Why?

Confirm that conversion tracking is turned on for the submit button in your campaign. See our guide on How to Enable Conversion Tracking.
