We wanted to swap gateways and pricing experiments without reworking the app. We wired our web funnel to a payment gateway that supports hosted checkouts and webhooks. That let us change offers and test new price points with almost no engineering.
Attribution was preserved by writing the utm and experiment id into the payment metadata. On success we pushed a normalized receipt to our backend which the app queries on sign in. The result: fast experiments, flexible pricing, and the ability to roll back changes quickly.
Which payment providers have you found easiest to iterate with when running price and offer experiments on web?
I used a gateway with good webhook support and metadata fields.
That let us write experiment ids into the payment and reconcile things server side. The dev effort was small and we could flip offers fast without touching the app.
Pick a gateway that exposes webhooks and lets you include campaign metadata. That metadata is how you map payments back to UTM and creative.
We ran price experiments iteratively and rolled back losers within hours. I prototyped the funnel with a JSON based generator to avoid building pages from scratch.
Stripe checkout plus webhooks. Fast and reliable.
For experimentation you want a payments partner that offers hosted checkout, metadata, and clear webhooks. That minimizes engineering work and makes AB tests trivial. Use metadata to stamp experiment ids and utm on the charge. Then push a normalized receipt to your backend and map it to the user.
If you also need subscription management use a billing layer that can mirror those web receipts for analytics. That combination enables rapid pricing tests with low engineering overhead.
We started with Stripe and then layered a simple subscription service. It was quick to test price points.
Stripe worked for quick experiments and had good dev docs.
Always test webhooks in staging before going live with price changes.
