withTag automates Instagram friend-tag promotions for your store. Connect an Instagram Business or Creator account, and withTag checks comments on your posts via the official Instagram API. When a customer tags the required number of friends, it creates a Shopify discount code and sends it by direct message. You control the reward tiers, coupon value, budget, and campaign dates. Duplicate and spam entries are blocked automatically, so you can run tag-to-reward campaigns without manual work.

• Automatic coupon issuance on qualifying comments
• Reward tiers based on the number of tags
• Coupon delivery via Instagram direct message
• Budget and campaign period controls
• Duplicate and spam-entry protection
