Add Partial.ly Checkout Button to Your Shopify Cart and/or Product Pages
- Generating a code snippet with your Partial.ly account.
- Adding the code snippet to your Shopify theme.
- Creating 2 Zapier zaps.
* If you are a merchant who was using our Shopify integration prior to this change, this option allows you to keep your Partial.ly checkout buttons as is. You only need to create the Zapier zaps to create the Shopify order.
With this method, a snippet of code is added to your Shopify theme. This code will generate a Partial.ly checkout button for your store. The first Zapier zap will listen for plan_opened webhook events from Partial.ly and create an associated Shopify order. The second Zapier zap will listen for plan_paid webhooks events from Partial.ly and mark the Shopify order as paid.
- Ability to keep/create Partial.ly script customizations.
- Place Partial.ly directly on your product pages.
- Can only be placed on cart and/or product pages.
- Not compatible with Shopify checkout, so limitations on shipping and taxes, which must be set up within your Partial.ly account.
(If you need the features of Shopify Checkout, see our other integration option to add Partial.ly as a Manual Payment Method to your Shopify Checkout page). - Won't work with Shopify discounts.
- Limitations on inventory management: You can set up the Zapier zap to obey your inventory rules when creating the Shopify order. However, Partial.ly cannot follow your inventory rules. This means the customer may be able to open the plan if there is no stock, but the Shopify order will fail. We recommend "hiding" out of stock products to prevent this.
- Log into your Partial.ly account at https://partial.ly/login.
- Go to the integration tool of your offer and select from the dropdown menu the option to generate code for the cart or product pages.
