Adding Scalapay through Stripe
If you already process with Stripe, adding a pay-later option is mostly a matter of enabling it and handling the redirect properly in your existing flow.
Getting live on Stripe
The order below matters — messaging before testing, testing before live traffic.
Enable the payment method
Turn Scalapay on in your Stripe dashboard so it becomes available to your checkout.
Connect your merchant account
Link your Scalapay merchant account so orders and settlements reconcile correctly.
Handle the redirect
The customer is taken to complete approval and returned to your confirmation page. Make sure your success and cancel URLs handle both outcomes.
Add on-site messaging
Show the installment figure on product and cart pages, which is where it influences the decision.
Six things specific to Stripe
The details that cause support tickets if you skip them.
Redirect handling matters
A customer who abandons at the approval step must land somewhere sensible. Test the cancel path as carefully as the success path.
Payment intents
Scalapay behaves as a redirect-based method, so build for an asynchronous confirmation rather than an immediate one.
Webhooks
Rely on webhook confirmation rather than the redirect alone to mark an order as paid.
Refunds
Issue refunds through your normal Stripe flow. We adjust the customer plan accordingly. How refunds work →
Reporting
Scalapay orders appear in your existing reporting alongside card payments.
Order limits
Orders run from $200 to $5,000, and you can set a tighter range for your catalogue.
Test the paths that are not the happy one
Every integration works when the customer does exactly the expected thing. Problems come from the other cases.
- A customer who abandons at the approval step — they must land somewhere sensible with the basket intact.
- A declined order — this is a normal outcome, not an error. Send them back to a checkout with other options available.
- A partial refund — check the customer plan recalculates and your own reporting matches.
- An order outside the range — validate against $200 to $5,000 before showing the option, so nobody is offered something that will fail.
Testing only the successful order is the most common reason an integration causes problems in its first week.
