Fynlo allows you to receive payments directly through trusted payment gateways such as PayPal, giving your clients a smooth and secure checkout experience. By connecting your PayPal API credentials to your Fynlo account, you enable your invoices to be paid through PayPal to PayPal or via card.
This setup uses PayPal’s REST API and requires entering your Public Key (Client ID) and Secret Key from your PayPal Developer account into Fynlo's platform. Follow the steps below to get started:
Log in to PayPal Developer Dashboard
Go to https://developer.paypal.com and log in using your PayPal Business account.
Create a New App
-
Go to Dashboard > My Apps & Credentials
-
Under the REST API apps section, click “Create App”
-
Enter an app name (e.g., “Fynlo Invoice Checkout”) and select your business account.
-
Click Create App
Get Your API Credentials
After the app is created:
-
You’ll see two environments: Sandbox (for testing) and Live (for real transactions).
-
Select Live and copy the following:
-
Client ID – this is your Public Key
-
Secret – this is your Secret Key
-
⚠️ Keep your Secret Key private. Never expose it on the client side.
🧷 Configure in Fynlo
Now go back to Fynlo and add these credentials to your payment settings:
| Field | What to Enter |
|---|---|
| Platform | PayPal |
| Checkout | Platform |
| Public Key | Paste your PayPal Client ID |
| Secret Key | Paste your PayPal Secret |
| Channel | (Optional) e.g., Online, Mobile |
| Remark | e.g., “PayPal US Gateway” |
| Status | Set to Active |
💡 What Happens Next?
Once this payment account is set:
-
Clients who click “Pay” on your invoice will be redirected to PayPal.
-
They can complete payment directly via their PayPal account or credit/debit card.
-
Fynlo will log the payment status and update the invoice accordingly.
