Getting Square payment errors

I have sucessfully linked my forms to an existing Square payment interface and show the connection to be in "test" mode. I have been testing payments for several days and been getting confirmation when signing into Square developer and matching the test transactions.

Today, I made a few minor changes to the forms (I have not changed the Square connection). Two of the forms continue to test properly but now am receiving the follow message when previewing the two other forms. All forms are using the same Square payment connection.

Error: Error: ApplicationIdEnvironmentMismatchError : Web Payments SDK was initialized with an application ID created in sandbox however you are currently using production.

I don't know what's gone wrong and can't find any specific help online. Any suggestions on how to troubleshoot and or fix would be greatly appreciated.

Hi Webmaster_BAA,

Thanks for reaching out to Jotform Support. Upon checking both of your forms, it shows that the Square Integration is in Live Mode.

If you are using a test credentials from your Square Developer Dashboard, make sure that your Square Integration on your form is in Test Mode. Can you try it again and see how it goes? We also have a guide on How to Integrate Square With Jotform that you can check out.

Keep us updated and let us know if you need any more help.

I’m confused.
Neither of the screen captures you sent me back, match the screens I’m seeing (see below). I’ve changed nothing. How is this possible. Both of my square connections show “Test”. Yours show “Live”.
Help me understand.

4. To resize it, click on your screenshot and then click on one of the boxes in the corners, and drag it inward.

That's it. Once we hear back from you, we'll be able to help you with this.

Hi Brad,

Can you try to remove your Product List field and reintegrate your Square Account with Test Mode? Let me show you how:

1. In Form Builder, click on the trash bin icon right next to the Product List field.
   
   
2. Click on Add Element + on the left side of the page.
3. Under Basic tab, add Product List into your form, click on Settings on the right under the Products tab.
4. Click on Add Payment Integration, select Square and make sure to change to Test Mode before connecting your test credentials from your Square Developer Dashboard.
   
   

Give it a try and reach out again if you have any other questions.
