# Creating a PayPal application

Head to PayPal's [developer portal](https://developer.paypal.com/developer/applications/) and create either a Sandbox or a Live application. I recommend creating a sandbox application (fake payments) while testing the bot and switching to live when you're ready to make the bot public.

After you get the credentials, add them to your `.env` file:

```properties
...
PAYPAL_SECRET=
PAYPAL_CLIENT_ID=
```
