Connecting to Church Community Builder is a little tricky to connect inside the Grow app because Church Community Builder requires the API username and password instead of your normal Church Community Builder login username and password.
Here are the steps to create an API username and password in CCB:
Log into your CCB account
Click the 'System Settings' gear icon
Click the 'API' wrench icon
Click 'Add a new API User'
Fill in the API user info.
Use the API username and password info you just created to create your data connection inside Grow.
Click Add Metric, then select Church Community Builder as the data source. Press the blue Connect button. You can then enter your brand new API username and password.
When you are done, press the blue Submit button.
And that's it! You are good to go.
