Paddle has two platforms, and the plugin supports both. Choose the one your account uses in the Paddle account type setting; the fields for that type appear straight away.
| Paddle Billing | Paddle Classic | |
|---|---|---|
| Who has it | Every account created after August 2023 | Older accounts that have not moved to Billing |
| Credentials you need | API key, client-side token, webhook secret | Vendor ID, API Auth Code, public key |
| Where to find them | Paddle → Developer Tools → Authentication | Paddle → Developer Tools → Authentication and → Public Key |
How to tell which one you have
Open Developer Tools → Authentication in your Paddle dashboard:
- If you see API keys and Client-side tokens, you have Paddle Billing. Follow Set up Paddle Billing.
- If you see a Vendor ID and Auth Codes (and a separate Public Key page), you have Paddle Classic. Follow Set up Paddle Classic.
Moving from Classic to Billing later
You can switch at any time: enter your Billing credentials and change the account type. Existing orders keep using the account type they were placed with, so their refunds still work.
