Setup Payment Provider
For SDK inline wp-admin checkout (Paddle or Stripe), see Inline checkout setup after you save provider credentials here.
Select a payment provider
The first step is to choose one of the payment providers we support: Stripe, PayPal, or Paddle. After you select a provider, the configuration page opens.
Configure keys and secrets
Each payment provider has its own credentials. Once you save them, License Bridge integrates that provider on your product landing page.
Stripe keys
Stripe uses a Publishable key and a Secret key. Log in to your Stripe account and open Developers → API keys. Use the Test mode toggle to switch between test and live keys.
Copy the publishable and secret keys into the configuration form and click Save.
PayPal keys
To set up PayPal, visit the PayPal Developer Dashboard and create a new application under My apps & credentials, if you have not already.
Open your application, copy the Client ID and Secret, paste them into the configuration form, and click Save.
Paddle keys
License Bridge uses Paddle Billing (not Paddle Classic). Open Product → Payment, select Paddle, and fill in the fields shown below.
Where to find credentials
In your Paddle dashboard, open Developer Tools → Authentication:
- API key — copy the key that starts with
pdl_sdbx_apikey_(sandbox) orpdl_live_apikey_(live) - Client-side token — copy the token that starts with
test_(sandbox) orlive_
For the Webhook secret, open Developer Tools → Notifications and create a notification destination:
- Set the destination URL to the webhook URL shown on the License Bridge form (it includes your product slug, for example
https://app.licensebridge.com/webhook/paddle/my-plugin) - Enable at least
subscription.created,subscription.canceled,subscription.past_due, andtransaction.completed - Copy the destination signing secret (
pdl_ntfset_*) into the Webhook secret field
The webhook URL on the form is generated for your active product. Use the Paddle sandbox dashboard when Sandbox mode is enabled.
Enable Sandbox mode while testing, then click Save. License Bridge verifies your credentials against the Paddle Billing API before storing them.
For full webhook setup details, see Paddle webhook setup.
Pricing plans auto-creation
Once you save payment provider credentials, License Bridge auto-creates your pricing plans on the provider via API. You do not need to create prices manually on Stripe, PayPal, or Paddle. Read more.
