This article covers the sponsorship feature, allowing you to set up sponsorships between a contact and a person to be sponsored.
Sponsorship can be set up through the Custom Contact Settings. The Labels section is system used if you are using the Cart/Product values and assigning these to your recurring transactions.
Typically, this set of features is used by organizations who are running things like monthly recurring child sponsorships. With this we see Carts/Products being created automatically via webhooks from an organization's website.
When you create a recurring transaction, you can create a Product to assign to the recurring transaction. It can be very helpful assign your transactions in this way, but it's not a required functionality.
Creating a sponsorship
Go to Contacts, and click on a contact profile to open it. and add a recurring donation. This will display a menu to create your products. Click Create Sponsorship.
Create your Product. The SKU is arbitrary here, but is required, and note if you are connecting this back to your website, it will need to be consistent there.
When you have set up your Recurring Transaction, you can then edit it from the Contact profile page. From here, you can now see these options. Start by editing your recurring transaction, and adding the Cart.
Next, fill in your values in the options which appear. This will create and assign your cart/product setup.
Keep an eye on Amount and Quantity. Amount is the singular dollar value of the recurring transaction. Quantity is the number of "sponsorships" that the Amount will buy.
These details will now be available as details on a transaction as well as for reports, etc.
