Some businesses do not get to pick their payment gateway. A bank, a parent company or a regional requirement hands you Worldline, and the job is to integrate it properly. That is less glamorous than the gateways with the slick developer docs, and it is exactly the kind of work we are happy to take on. We connect sites and apps to Worldline and make the payment side reliable end to end.
Techalyst is a Vancouver software studio that builds and runs payment flows for businesses across the Lower Mainland.
What we integrate
- Hosted checkout and the redirect flow, wired correctly into your app.
- Tokenised payments, so repeat customers do not re-enter card details and you stay out of scope.
- Webhooks and status callbacks, so a completed or failed payment always reaches your system.
- Refunds and reconciliation, with records that match Worldline's to the cent.
Why the callback side matters
The usual broken gateway integration trusts the customer being redirected back instead of the server-to-server callback, so a payment that succeeded never gets recorded, or a failed one looks complete. We build the callback and webhook handling to be logged and idempotent, so the truth comes from Worldline and nothing slips through.
Where this fits in Vancouver
Whether Worldline is a requirement handed to you or the gateway your processor supports, you want someone who will read the docs properly and handle the edge cases. We work with businesses across the Lower Mainland who need a specific gateway integrated correctly, not just the popular one.
Other gateways too
Worldline is one of several gateways we integrate. We also do Stripe and PayPal, and we can run more than one side by side when your customers expect a choice.
Frequently asked questions
Can you add Worldline to my existing app?
Yes. Connecting an existing site or app to Worldline is exactly the kind of work we take on.
Do you handle tokenised and recurring payments?
Yes, where Worldline supports them for your account, we build tokenisation and recurring flows.
Can you fix a Worldline integration that drops payments?
Yes. Callback and webhook bugs that lose payments are common things we are called in to fix.
Can you run Worldline alongside another gateway?
Yes. We commonly run more than one gateway so customers can choose, reconciled on your side.
