We’re committed to helping publishers and creators maximize revenue at every stage of the commerce journey. The Sovrn Commerce platform continues to evolve around that goal, delivering new features and tools designed to unlock incremental earnings and streamline affiliate monetization.
As part of our Winter 2026 release, we’re introducing the Promo Codes API — a new way to surface verified, product-specific deals and drive higher conversions.
Turning purchase intent into action
Deals and promo codes remain one of the most effective tools in the affiliate marketer’s playbook. When a shopper sees a relevant discount tied directly to the product they’re considering, it creates a sense of urgency — while also building trust and reducing friction at checkout. The result? Higher engagement, stronger click-through rates, and improved conversions.
Until now, accessing product-level codes at scale often required manual research or reliance on broad, sitewide offers that didn’t always match the specific item a reader wanted. The new Promo Codes API changes that.
How it works
The Promo Codes API returns relevant, product-specific codes based on a retailer’s product URL. With a single API call, publishers can retrieve applicable offers tied directly to a specific item — making it easy to surface targeted deals when purchase intent is highest.
Each API response includes key merchant information, the current verification status of the promo code, and affiliate-ready URLs with tracking parameters already applied. In other words, the heavy lifting is done for you. Instead of validating codes or building tracking links manually, you can integrate ready-to-use deals and code data directly into your commerce experience.
This allows you to:
- Add relevant discounts to product pages, buying guides, and deal roundups
- Enhance shopping experiences with verified, up-to-date offers
- Drive conversions with savings that align directly to the selected product
Smart ranking — and smarter tracking
Not all deals are created equal, and showing the right one matters. Codes returned by the Promo Codes API are ranked by a combination of factors, including performance and relevance to the specific product URL. Verified codes are returned first, followed by unverified candidates (if enabled). This ensures the most compelling and applicable offers appear first, helping you present the best possible savings opportunity to your audience.
The API also supports optional parameters to enhance tracking and reporting. Publishers and creators can include attribution details such as source, medium, campaign, and more. This added flexibility makes it easier to measure performance across placements, campaigns, or traffic sources — and optimize accordingly.
Why product-level deals matter
In order to earn affiliate revenue, you need to drive conversions. And conversions require a delicate balance of trust, relevance, and value. By delivering product-specific deals at the moment of decision, publishers and creators can:
- Increase engagement by adding tanging savings to editorial recommendations
- Boost conversions with timely, relevant deal codes
- Set your content apart from competitors offering generic or outdated deals
- Capture incremental revenue from high-intent shoppers
For deal-focused publishers and creators, this feature enables automation and scale. For content-driven publishers and creators, it enhances storytelling with a clear value-add. And for commerce teams focused on performance, it introduces another way to improve monetization without disrupting the reader experience.
