Bundle App Compatibility

Does Regios work with bundle apps?

It depends on how the bundle app is implemented:

• Cart Transform Functions API: Yes - the discount will apply to the "bundle" product.
• Draft orders API: Maybe, but probably not

Please ask your bundle app provider which they use.

Can Regios apply discounts to individual components of a bundle?

No. This is due to limitations in Shopify itself we can't work around:

• Discount Functions can't see line item components.
• Product Discount Functions can only target cart line IDs, not line components.

This applies to custom apps that use the Cart Transform Functions API, as well as any 3rd-party app that uses that API.

Cart Transform Compatibility

• Cart Transform Functions run before discounts.
• Discount Functions can't see line item components.
• Product Discount Functions can only target cart line IDs, not line components.

Draft Order Compatibility

Draft orders CAN be used with Shopify Functions API discounts (such as Regios Discounts). HOWEVER, the app that creates draft orders must enable specific API flags to allow combining with other discounts. Most apps that create draft orders simply do not do this, which is completely outside our control. For more information, please read our discount stacking guide, which goes into more depth on discount combinations.
