PayPal 来自 Braintree 沙箱的集成错误：PAYPAL_SANDBOX_ACCOUNT_NOT_LINKED

Question

I got this error when I try to test my PayPal integration from Braintree.

Here is my client code (actually copy from official site and make little modification):

braintree.client.create({
    authorization: ClientToken
}, function(err, clientInstance) {
    if (err) {
        console.error(err);
        return;
    }

    // Create a PayPal Checkout component.
    braintree.paypalCheckout.create({
        client: clientInstance
    }, function (paypalCheckoutErr, paypalCheckoutInstance) {
        // Stop if there was a problem creating PayPal Checkout.
        // This could happen if there was a network error or if it's incorrectly
        // configured.
        if (paypalCheckoutErr) {
            console.error('Error creating PayPal Checkout:', paypalCheckoutErr); // Error from this line
            return;
        }
    });
});

Error creating PayPal Checkout: 
{
    name: "BraintreeError",
    code: "PAYPAL_SANDBOX_ACCOUNT_NOT_LINKED",
    message: "A linked PayPal Sandbox account is required to use PayPal Checkout in Sandbox. See https://developers.braintreepayments.com/guides/paypal/testing-go-live/#linked-paypal-testing for details on linking your PayPal sandbox with Braintree.",
    type: "MERCHANT",
    details: undefined
}

I have actually link my PayPal sandbox account (from the Braintree control panel) and surprisingly cannot find any useful information about this error. Of course I have read through https://developers.braintreepayments.com/guides/paypal/testing-go-live/node#linked-paypal-testing .

Answer 2

_{Full disclosure: I work at Braintree. If you have any further questions, feel free to contact support .}

There are two sandbox accounts that you need to link together: your Braintree sandbox , and your PayPal sandbox .

Double check that you have followed the instructions in Braintree's documentation to link your PayPal sandbox account to your Braintree sandbox account within the Control Panel .

If you continue to see this error, please contact Braintree Support for assistance.

Answer 3

I have same issue.

Turns out Paypal need me to verify my phone number and email address. But I haven't login to Paypal since 2016, so my information goes all wrong, finally I have to re-create my paypal account.

Answer 4

Braintree doc: https://developer.paypal.com/braintree/docs/guides/paypal/testing-go-live#linked-paypal-testing

You have to link your Paypal account to Braintree

In order to link a PayPal sandbox test account to your Braintree sandbox account, you will need the API credentials for that PayPal sandbox test account.

If you don't already have a PayPal sandbox test account for testing your Braintree integration, create a new one by following these steps:

1. Create a PayPal business sandbox account:

   • Log into the PayPal Developer Dashboard
   • Navigate to Sandbox > Accounts
   • Click Create Account
   • Select the same Country as your Braintree sandbox account
   • Select the account type as Business

2. Go to the Create New App page

   • Create an app to get sandbox API credentials
   • Select the same sandbox developer account as the test account created in step 1

3. Note the following Sandbox API Credentials for the new app you created:

   • Email address associated with this app
   • Client ID
   • Secret

Once you have those PayPal sandbox API credentials, enter them in your Braintree sandbox:

1. Log into your Braintree sandbox Control Panel
2. Navigate to Settings > Processing > Payment Methods > PayPal
3. Click Link Sandbox
4. Enter the Email address, Client ID, and Client Secret for your PayPal sandbox test account
5. Click Link PayPal Sandbox
