Per-creator discount codes run through your Shopify connection, so connect Shopify first under Settings, then Integrations. Set them up on the campaign brief, on the Settings step:
Set the discount code type to Shopify.
Pick an existing discount from your store.
Set a code template using the Name, Handle, or Discount macros.
The Cirqle generates a unique code per creator from that template, so every sale is attributed to the right creator. The Manual type is the alternative: one code shared by everyone, with no per-creator attribution.
Two things to plan for:
The discount code type cannot be changed once you have contracted creators on the campaign.
Keep Shopify connected for the full campaign. Sales made while it is disconnected cannot be attributed reliably.
If code creation fails, check that the connection is active and that your Shopify user has permission to create discounts. Still stuck? Message us in the chat with the creator name and we will look at it.
