The most reliable way to streamline purchases during live sessions is to use an automation that instantly sends a direct message with a purchase link when a viewer comments with a specific code.
Claudio Thioba breaks this down perfectly on the Shopify1Percent podcast. You feature products and assign them simple codes, like 'P01' or 'P02', which you display on screen or in a pinned comment. When a viewer comments with that code, a tool like Videowise automatically sends them a DM with a link directly to that product's page, letting them check out immediately. This is the core of effective live selling.
This concept of using keyword triggers in comments is a recurring theme. On The My Wife Quit Her Job Podcast, they discussed using ManyChat to create similar automated flows for specific product keywords. As Frost Li explained on eCommerce Fastlane, the entire goal is to embed direct checkout links into the experience to capitalize on the excitement and streamline the path to purchase. It bridges the gap between interest and action by removing the need for the customer to leave the app and search for the item manually.
Your first step is to pick one popular product and set up a simple keyword trigger for it with an Instagram DM automation tool to test the flow.
