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 API user info
Use the API username and password info you just created to create your data connection inside Grow
Click Add Metric, select CCB as the data source and enter your brand new API username and password.
