Square WebPay Errors and Issues

Here are some common Square WebPay issues and the steps required to fix them.

The provided OAuth access token has expired. You must renew the access token via the Renew Access Token endpoint.

Situation:
Customer is attempting to complete a purchase and paying via Square. They login, provide payment details, and click the Continue button, and they are shown this message.

Or you get an email that says

[ACCESS_TOKEN_EXPIRED]: The provided OAuth access token has expired. 

Fixing the Problem (short procedure):

This will generally work. If it doesn’t, use the long procedure below.

1. Open Square in your Zen Cart Admin by going to Admin > Modules > Payment > Square WebPay and clicking Edit.
2. Click “Update” at the bottom of the sidebar for Square WebPay. This should refresh the token.

Make a test purchase to verify that the problem has been fixed.

Fixing the Problem (long procedure):

Action to Resolve:

1. Open Square in your Zen Cart Admin by going to Admin > Modules > Payment > Square WebPay and clicking Edit. Be sure to click Edit before going further.

2. Go to https://connect.squareup.com/apps, click “Sign In” and open the app you are using for payment.

3. Click the OAuth link on the left, then click the “Replace secret” button.

4. Click “Show” on the Production Application secret, and paste it into your Zen Cart Admin in the Application Secret (OAuth) field.

5. Click “Update” at the bottom of the sidebar for Square WebPay.

Make a test purchase to verify that the problem has been fixed.

I get a white screen in Admin where Square Configuration should be!

If you forgot to click Edit in the first step, you may get a blank screen on the right hand side of the page when you finally do click Edit.

Here’s what to do if that happens:

• Edit the URL in the address bar, which will end with

&action=edit

Change this to

&action=delete 

and press Enter. Press the “Remove Module” button and remove Square WebPay. Then re-add it using the reinstall instructions.

Preventing the problem in the future

This issue can be prevented using the steps in Square - Avoiding Token Expiry.

Two Factor Authentication

Square uses two factor authentication (either via SMS or an authenticator app). If you have multiple people accessing your Square dashboard (either multiple store admins or a store admin and a web developer), be sure that both of them can authenticate independently. (Without this, the one who can’t authenticate will be locked out until the other one is available.)

As a short term solution, you can disable two factor authentication in the Square Dashboard as follows:

• click on your name at the top right of the page, then click Account Settings.
• On the left hand side of the page, under *Account, click Personal Information.
• Click Disable 2-step verification.

Note: The Square Dashboard is not the same as the Developer Portal. To get to the Dashboard from the Portal, clcick your name at the top right, then click “Seller Dashboard.”
