Selling a Product by Auto DM: Comment BUY, Get Checkout
Comment BUY, get a checkout link, pay, download. Viralyze handles the chain: a product page is built for you, you attach it to the keyword BUY on a reel, and every BUY comment receives the checkout link by DM in about a second. The platform fee is 0%, payment is by UPI, card or net banking, and payouts reach your bank weekly.
This article covers the setup, a worked example for a digital seller, and the small wording choices that make the difference between a reel that sells and one that just gets likes.
Which products can I sell this way?
Digital downloads, physical products, online courses and 1:1 sessions, each with its own checkout page. For a comment-to-buy reel, digital products work especially well because delivery is instant: the buyer pays and the file or course access is theirs.
A photographer selling a Lightroom preset pack is a clean example. The product page has a name, a price of ₹499, a short description and the download attached. That page is what the BUY automation sends.
How do I set up the BUY automation?
1. Create the product in the shop section with its price and file. Viralyze makes the checkout page. 2. Open Auto-DM and pick the reel that shows the product in use. 3. Add keywords: BUY, "price", "link", "want". Different keywords can send different replies if you like, so "price" might send the price in text and BUY might send the checkout directly. 4. Write the DM: "Here is the preset pack. ₹499, instant download after payment. Tap below." 5. Attach the product page, test it with the live tester, and turn it on.
Set an auto-pause if the offer is limited, for example after 100 DMs or on a date, so a launch price does not run for ever.
Does a follow-gate make sense on a BUY keyword?
Usually not. The person has told you they want to pay; asking them to follow first adds friction at the exact moment you want none. Save the follow-gate for free lead magnets where a follow is a fair exchange.
If you do want followers from a sales reel, add a second keyword on the same reel, such as "FREE" for a sample preset with the gate on, and leave BUY open.
What does the buyer's side look like?
They comment BUY, see a public reply like "Check your DMs 💌", open the DM, tap the link, and land on a checkout page with the product, price and a pay button. They pay by UPI, card or net banking through an RBI-authorised aggregator. The download link appears immediately after payment.
Each buyer becomes a contact in your list with a source tag for that reel, so a month later you can export a CSV of everyone who bought the preset pack and tell them about the next one.
How do I know whether the reel is selling?
Open the automation's funnel: comments, matched, delivered, clicked, signed up. For a product, the last step is the purchase. If comments are high and clicks are low, the DM wording needs the price and the benefit up front. If clicks are high and purchases are low, the product page needs a clearer description or a different price.
The home screen shows revenue over 7, 30 and 90 days, and the top reels by DMs list tells you which product demonstrations to repeat.
Frequently asked questions
**Is there any commission on sales made through the DM link?** No. The platform fee is 0% on the Starter and Pro plans; payment processing is handled through the aggregator and payouts arrive weekly.
**Can I sell a physical product with BUY?** Yes. Physical products get a checkout page too; you handle shipping after the order and the buyer's details are in your contacts.
**What if someone comments BUY twice?** Instagram allows one private reply per comment, and Viralyze follows that rule, so each comment can receive one DM and the person is never spammed.
