​
Subscription configuration

FunnelFox automatically creates webhooks in your Solidgate account and syncs your products after setup. Products created in Solidgate become available in the Element tab of your Checkout element. Configure Solidgate products in your funnels:

​
Digital wallets

FunnelFox supports Apple Pay and Google Pay with Solidgate for faster checkout. Apple Pay requires domain verification, while Google Pay works by default. Once your setup is complete, configure wallet buttons directly in your funnels.

​
Apply Pay

Apple Pay for Stripe requires domain verification before you can use it. To enable Apple Pay:
  1. Go to Developers > Apple Pay Domains in Solidgate.
  2. Click + Add new domain at the top right.
  1. Paste your project domain from Settings > Domains in FunnelFox and click Add. If you have a custom domain, add it as well.
To use Apple Pay in funnel preview mode, add http://app.funnelfox.com/ as a domain.
  1. Go to Settings > Domains in FunnelFox.
  2. Select Solidgate under Apple Pay domain verification.
  1. Click Save.
Apple Pay will become available in your funnels after domain verification completes.

​
Google Pay

Google Pay with Solidgate works by default and requires no configuration.

​
Wallet button configuration

Click + Add in the Visual editor, then select Paywall Elements > Wallet Button and set your configuration:
  • Payment Provider: Solidgate
  • Config source: Defines how the button is configured.
    • Independent: Configure separately from your Checkout element. Cannot be placed on the same screen with a Checkout or another wallet button.
    • Linked: Inherits product configuration from your Checkout element on the same screen. Requires the Apple Pay / Google Pay payment method to be enabled in the Checkout. You can include multiple linked Wallet Buttons and Checkouts on the same screen using conditional visibility.
  • Fallback: If the wallet button fails to load or initialize, a simple button appears that triggers the action you’ve configured.
For independent wallet button configuration, you can also set the following:
  • When Payment Succeeds: Navigation action to trigger when payment is completed.
  • When payment fails or is declined: Navigation action to trigger when payment fails due to a decline or error (including 3DS).
  • When payment is cancelled by user: Navigation action to trigger when user clicks the cancel button (if available).
  • Entitlement: Access level ID for subscription manager.
  • Flow type: Defines the payment flow depending on what you sell.
    • One-time
    • Subscription
  • Order description: Description to be sent for order details to Solidgate.
  • Plan/Price: Define the Solidgate product or one-time price to sell.
  • Custom purchase value: Override the actual price in analytics and marketing tracking events. Use this for value-based optimization where you can send a predicted LTV.
    • Leave empty to use the actual product price.
For customers with slow internet connections, the linked wallet button may load before the related Checkout element. In this case, the wallet button won’t function, and the fallback button will be triggered automatically.
