Source codes are a great way to internally track email campaign performance. Use source codes to track how an email send did, or to attribute the funds raised to a particular marketing channel.
Source codes can be added on a per-form basis using the form builder tool. You can also set default source codes in your Revv settings. This default will automatically set the source code for each new form you create with the default you set in your settings. This, however, will not apply to any forms you've already created.
Revv writes these source codes to Stripe metadata so you can view the source code for each donation made in your Stripe payment exports.
You can also override the source code for any donation using URL parameters. The syntax for this is ?sc=SOURCECODE. To learn more about using URL parameters click here.
