Attribute Influencer Revenue with Custom Web Checkout Links

Stop guessing which creator drove your subscriptions — give each one a unique web checkout link and trace every paid conversion back to its source.

Why it matters

Most influencer budgets get spent on a hunch. You can see clicks and follower counts, but not which creator actually drove paid subscriptions, so spend keeps flowing toward “we think it worked.” For subscription apps, web-to-app is a rising frontier: teams want web and app monetization to move together and want to understand the value of web traffic. Custom checkout links turn that traffic into something you can measure at the level of an individual creator and offer.

What you can do with Superwall

• Hand each influencer a unique checkout link. Web checkout links turn any placement in a campaign into a unique URL, for example yourapp.superwall.app/creator-promo. Create one per creator and share, send, or email it.

• Tag the traffic source for attribution. Append query parameters to the link to identify the creator, filter which audience sees the paywall, or prefill the checkout email with ?email=.

• Wire the buyer’s identity into the purchase record. The uid, user, or app_user_id parameters set the subscription identifier, which appears in Stripe metadata and webhooks so a paid conversion ties back to the exact link.

• Test the offer behind the link. Web checkout campaigns work like standard Superwall campaigns, with A/B testing and targeting on the paywall the link opens.

• Price for each market automatically. Stripe Adaptive Pricing shows local currency based on the customer’s location, with no campaign changes.

• Measure where checkout drops off. The Checkout Conversion chart shows the percentage of users who convert after starting checkout, so you can compare creator links and offers.

How it works

• Connect Stripe and create a web checkout app. Link Superwall to Stripe and add products for your web paywalls.

• Build a campaign and placement. Each placement becomes a unique URL that shows your paywall.

• Append attribution parameters. Add a source tag plus uid/user/app_user_id to each creator’s link so the data flows into Stripe metadata and webhooks.

• Redeem back in the app. After purchase, the buyer is deep-linked back into your app to unlock their entitlement via the SDK’s post-checkout redirection and delegate methods.

Proof from customers

This maps to two of the strongest signals in Superwall’s customer research. Web paywalls / web2app came up in 30% of analyzed calls, with customers asking to move faster and understand the value of web users. Marketing, attribution, and UA came up in 15% of calls. The docs explicitly call out influencer campaigns as a supported use case for query-parameter links, alongside personalization and seasonal events.

Customers describe wanting an “air traffic control” view of monetization, with everything considered as a whole instead of fragmented across web and app.

Use cases

• Per-creator links: one tagged checkout URL per influencer, so paid conversions trace back to the source.

• Seasonal and promo drops: a dedicated link per campaign moment, with the offer A/B tested behind it.

• Affiliate and partner deals: attribute revenue to partners using the same query-parameter pattern.

• Email and DM funnels: prefill the checkout email and personalize the paywall with parameters.
