First, navigate to the campaign where you'd like to connect the BrightLocal integration, then click "Integrations" from the menu on the left side of the screen.

Next, either search BrightLocal in the upper right search box or click the Local category, then click BrightLocal.

Then click Connect Account.

In the window that appears, enter the API Key for your BrightLocal account. If you're not sure where to find it, please see here or contact BrightLocal support. Once you've entered your API Key, click "Save".

Next, select the client you want to connect and click "Save".

If the client that you would like to connect is under a different BrightLocal account, you will need to enter different credentials to access that account. To do so, click the button that says "Connect New Account" and follow the above steps.
