## How it works

<Steps>
  <Step title="Connect your PSP">
    Choose your payment provider and enter your API keys, if needed. FunnelFox securely stores them and connects your account automatically.
  </Step>

  <Step title="Automatic product sync">
    FunnelFox automatically fetches your products, prices, and discounts from the PSP. They're then available in Checkout elements.
  </Step>

  <Step title="Configure Checkout element">
    Add products to your Checkout element in the funnel Editor, and you're ready to accept payments.
  </Step>

  <Step title="Add wallet buttons">
    Place a [Wallet button](/docs/elements/wallet-button) on your
    paywall to let customers pay in one click with Apple Pay or Google Pay.
  </Step>
</Steps>

<Info>
  FunnelFox never stores or processes payment card details. All sensitive
  payment data is handled directly by your chosen PSP.

<sup>\*</sup>Via [API keys setup](/docs/integrations/payments/stripe#deprecated-api-keys-setup-flow) with European Stripe accounts only.

<sup>\*\*</sup>Available manually through the Support tool in your FunnelFox Billing account and through the [cancellation API](/docs/api-reference/cancel-subscription).

### 2. Configure products in funnel

Once integrated, FunnelFox automatically fetches your products, prices, and discounts from the PSP.

No matter which PSP you connect, all subscriptions in your funnels are configured through the **Element** tab of the [Checkout](/docs/elements/checkout).

While editing the **Payment Provider Settings** section there, you can configure:

* [Free trial](/docs/elements/checkout#free-trial)
* [Paid trial](/docs/elements/checkout#paid-trial)
* [Offers](/docs/elements/checkout#offer) (intro, promo, coupons)
* [Upsells](/docs/elements/checkout#upsell)

### 3. Add wallet buttons

Wallet buttons let customers pay in one click using Apple Pay or Google Pay,
without typing card details. Because they skip manual card entry and use
payment credentials customers already have on their device, they reduce
checkout friction and typically boost conversion rates by up to 30%.

Wallet buttons are supported by Stripe, Solidgate, and FunnelFox Billing.
With Paddle, the one-click experience is implemented as the
[Apple Pay Express Checkout](/docs/integrations/payments/paddle#apple-pay-express-checkout)
instead.

Go to the [Wallet button article](/docs/elements/wallet-button) to set it up
in your funnels.
