Turn Any Link Into a Discount: Introducing Auto-Apply Coupon Codes

Introduction

One of the most common requests we've heard from our merchant community is simple: "Is there a way to create a link that automatically applies a coupon code?"

Now the answer is yes — and it works anywhere you're already marketing. Drop it in an email campaign, embed it in a social ad, or add it to an SMS and shoppers land on your store with their discount already applied. No extra steps, no manual entry, just a seamless path from click to checkout.

Setting it up

Adding a coupon to any link is as simple as appending ?couponcode=YOURCODE to any BigCommerce storefront URL — your homepage or a product page. For example:

https://www.mystore.com/?couponcode=welcome10

That's it. Drop that link into your email campaign, social ad, SMS, or wherever your shoppers are, and the discount does the rest.

Note: The couponcode parameter works on storefront pages like the homepage or product pages. It does not work on /checkout URLs.

How shoppers experience it

Once a shopper clicks your link, the coupon is applied automatically the moment they land on your store — no manual entry required. It works seamlessly across a range of real-world shopping flows:

• A shopper clicks the link from a social channel (e.g. Instagram, TikTok) and goes straight to the cart.

• A shopper clicks the link from a campaign email, browses the store, adds items, then heads to checkout.

• A shopper already has a cart and then clicks the link.

Running multiple promotions? No problem. Auto-apply also supports multi-coupon flows, so shoppers can arrive via one coupon link and apply an additional code on top. For example, a shopper might land via a welcome10 email link and also apply a freeshipping code — both discounts apply seamlessly.

Where to use coupon code links

• Email marketing: Embed the coupon link in your CTA button. When subscribers click "Shop Now," the discount is already applied.

• SMS campaigns: Short links with embedded codes mean your mobile shoppers get a one-tap path to savings.

• Influencer and affiliate partnerships: Give partners a URL with their unique code built in. Attribution stays clean and the experience is frictionless.

• Social media and paid ads: Pair a compelling offer with a link that delivers on it — instantly.

• QR codes: Print a QR code linked to a coupon URL on packaging, signage, or event materials. Scan and shop, discount included.

Compatibility

Auto-apply coupon links are flexible and support a variety of BigCommerce setups:

• Coupons created in the legacy coupon code functionality (Marketing > Coupon codes)

• B2B Edition Checkout

• Multi-coupon flows

• Stencil-based storefronts only*

*Note: Auto-apply coupon links currently support Stencil-based storefronts. Headless storefronts are not supported at this time.

The final word

​​Getting started is easy:

1. Create your coupon promotion in your BigCommerce control panel.

2. Add the coupon code link to your email, SMS, or social campaign.

3. Test your campaign to ensure ?couponcode=YOURCODE appears on the storefront URL (homepage, product page).

4. Publish and share your campaign across all marketing channels.

Whether you're running a flash sale, rewarding loyal subscribers, or powering an influencer campaign, auto-apply coupon codes make every link work harder.
