Direct answer: For most international-facing apps, hosted checkout (Stripe Checkout or PayPal's hosted buttons) is the right default — it keeps raw card data off your servers, minimizes PCI compliance scope, and gets local payment methods for free. Custom API-driven forms are worth the extra engineering only when a fully bespoke checkout UI is a genuine requirement, not a default preference.
This guide covers the same category of decision as our bKash, Nagad & SSLCommerz integration guide but for the gateways that matter to an internationally-facing product rather than a Bangladesh-domestic one.
Hosted checkout vs. a custom payment form
Stripe Checkout and PayPal's hosted flows handle the entire payment form, keep raw card numbers off your infrastructure, and automatically support local payment methods (Apple Pay, Google Pay, region-specific options) without extra integration work. Building with Stripe Elements or the raw API gives full design control over the checkout UI but adds meaningful engineering time and pulls more compliance scope onto you. Default to hosted unless a custom checkout is a genuine, specific product requirement.
What PCI compliance actually requires
Using a hosted or tokenized form keeps you in the simplest compliance tier (Stripe and PayPal both publish guidance on this as SAQ A) — you still complete a self-assessment questionnaire, but raw card data never touches your servers. A fully custom card form handling raw card numbers directly moves you into a much heavier compliance tier with real ongoing obligations. For nearly every business, this alone settles the hosted-vs- custom decision.
Subscription billing: let the provider own the state
Stripe Billing (and PayPal's equivalent subscription products) manage the full recurring billing lifecycle — charge scheduling, failed-payment retries, proration on plan changes. Your application should treat the provider's subscription state as the source of truth and sync to it via webhooks, rather than maintaining a separate "is this user subscribed" flag in your own database that can silently drift out of sync after a failed renewal or a provider-side change.
Why webhooks are not optional
A client-side success redirect after checkout is not proof a payment settled — network interruptions, browser crashes, and fraud review holds can all break that path after the user sees a success screen. Order fulfillment, subscription activation, and any action with real financial consequence should be triggered by a verified server-to-server webhook event from Stripe or PayPal, never by the client-side callback alone. This is the single most common cause of "the customer says they paid but the order never shipped" disputes.
Offering both providers together
Running Stripe and PayPal side by side is common for apps serving multiple countries, since payment method preference varies meaningfully by region. Treat it as two full integrations rather than one primary provider with a secondary bolted on — each has its own webhook events, its own dispute process, and its own edge cases to handle correctly.
Why this takes three months, not three days
A basic Stripe Checkout redirect for a single one-time payment can genuinely ship in under a day. A real production integration — subscription billing with proration and failed-payment retry logic, webhook-driven order fulfillment, multi-currency handling, and a marketplace or platform payment split (Stripe Connect or PayPal-equivalent) — is realistically a multi-week to multi-month effort, and founders are consistently surprised by this gap. The difference is not the payment button; it is the state machine behind it: what happens on a failed renewal, a disputed charge, a webhook that arrives out of order, or a refund that needs to reverse a multi-party payout. Scope the integration against your actual billing model, not against how long the checkout button itself takes to wire up.

Frequently Asked Questions
Hosted Checkout is the right default for most businesses — Stripe maintains the payment form, handles PCI compliance scope, and supports local payment methods automatically, at the cost of some UI customization. A fully custom form using Stripe Elements or the raw API gives complete design control but adds real engineering and compliance work — that tradeoff is only worth it when a custom checkout flow is a genuine product differentiator, not a default preference.
Using Stripe Checkout, Stripe Elements, or PayPal's hosted buttons keeps raw card numbers off your own servers entirely, which qualifies you for the simplest PCI compliance tier (SAQ A) — you still complete a self-assessment questionnaire, but the scope is small. Building a fully custom card form that touches raw card data directly puts you in a much heavier compliance tier. For nearly every business, letting Stripe or PayPal handle the sensitive fields is both simpler and safer.
Stripe Billing manages the subscription lifecycle — creating a customer, attaching a payment method, running recurring charges, handling failed-payment retries (dunning), and prorating plan changes — while your application listens for webhook events (payment succeeded, subscription canceled, payment failed) to keep its own database in sync. The subscription state of record should be Stripe's, not a separately maintained flag in your own database that can drift out of sync.
A successful client-side payment confirmation does not guarantee the money actually settled — network failures, browser crashes, and fraud holds can all interrupt that path. Webhooks are the payment provider notifying your server directly and reliably when the actual state changes (payment succeeded, disputed, refunded), which is why order fulfillment and subscription access should be triggered by a verified webhook event, never by the client-side success callback alone.
Trusting the client-side redirect or success callback as proof of payment, instead of confirming the transaction server-side via a verified webhook. This produces a specific, damaging failure mode: an order marked paid and fulfilled when the actual charge failed or was later disputed, because the confirmation logic trusted the browser instead of the payment provider's server-to-server notification.
Yes, and offering both is common for international-facing apps, since payment method preference varies significantly by country and demographic. The integration work roughly doubles — each provider has its own webhook events, its own subscription model if applicable, and its own dispute/refund process — so it should be scoped as two integrations, not one with a second option bolted on.
