Rakuten Coupon Feed Explained

What it is

Think of the coupon feed as a vending machine stocked with your current offers. Instead of every coupon publisher messaging you to ask "what's your latest code?", they pull from one shared, always-up-to-date list. You load the machine; they take what's relevant to their audience and display it on their site.

In practical terms it's a set of records, each one describing a single offer: the code itself (or "no code needed" for an automatic deal), what the offer is, when it starts, when it expires, and whether there are any restrictions like "new customers only" or "excludes sale items". Rakuten holds that list centrally and makes it available to the publishers in your programme so they can populate their coupon pages without you lifting a finger for each one.

The key thing to understand is that the feed is a distribution tool, not a tracking tool. It carries the message; your tracking links and SubIDs are what actually record the sale. The two work together, which is why a tidy feed and clean tracking go hand in hand.

Why it matters

Coupon and deal sites are among the highest-traffic publishers in most programmes. Shoppers who are one click from buying often open a new tab and search "[your brand] discount code" before they check out. Whatever they find there decides whether the sale completes — and whether a partner gets credited for nudging it over the line.

If your feed is empty or stale, two bad things happen. First, partners display expired or invented codes, shoppers hit "code not valid" at checkout, and some abandon the cart entirely. Second, you lose control of the narrative: enterprising sites will scrape codes from anywhere, including ones you never authorised, and you end up paying commission on discounts you didn't sanction. A well-kept feed is how you stay the single source of truth for what's actually live.

How it works

From the advertiser's side, here's the typical flow:

1. Create the offer in your Rakuten dashboard. Open the coupons or offers section and add a new entry for the promotion you're running.
2. Enter the code and the human-readable description. Be exact with the code (capitalisation can matter on some carts) and write the description the way a shopper would read it, e.g. "15% off orders over £50".
3. Set the start and end dates. The feed uses these to switch the offer on and off automatically, so partners only ever show codes that are currently valid.
4. Add the restrictions and terms. New-customer-only, category exclusions, minimum spend — spell these out so publishers can display them and pre-empt failed checkouts.
5. Choose who can see it. Some offers are public to all partners; others you may want to keep exclusive to a single publisher. Set the visibility accordingly.
6. Publish and let the feed propagate. Once live, the offer flows into the feed that publishers read. Allow a little time for partners' systems to pick it up — it isn't always instant.
7. Retire offers cleanly. When a promotion ends, let it expire on its end date or remove it. Don't leave dead codes sitting in the feed.

Common mistakes

• Leaving expired codes live. The single most common failure. An old code shown on a deal site leads straight to a "not valid" message at checkout and a lost sale. Set accurate end dates and audit the feed monthly.
• Vague or missing terms. If "new customers only" isn't in the description, publishers can't show it, shoppers get rejected at the till, and you field the complaints. Put every condition in writing.
• Mismatched codes. The code in the feed must match exactly what your e-commerce platform accepts. A trailing space, a lowercase letter, or a code that's been changed on your site but not in the feed all break the experience.
• Treating the feed as set-and-forget. Offers change, seasons change, and your checkout rules change. A feed that nobody owns drifts out of date within weeks.

Reporting tips

Once codes are flowing, your dashboard tells you whether they're working. Look at performance by coupon publisher first — these partners should show a healthy volume of clicks converting to sales. A coupon site with lots of clicks but few orders is often a sign of a broken or expired code, so cross-check what they're displaying.

Pay attention to which specific offers convert. If "free shipping" outperforms "10% off" for your audience, that's a planning insight for your next campaign. Use SubIDs on your coupon partners' links so you can attribute performance down to the placement, not just the publisher. And keep an eye on average order value from coupon traffic — if a code is cannibalising full-price sales rather than driving incremental ones, the reporting will show a dip in AOV worth investigating.
