Yes, you are correct. In sandbox entering the card information isn’t currently available. Also at this time the ability to test the `redirect_url` in sandbox isn’t currently available. When a payment is completed and the customer is redirected Square will append the following to your URL:

```auto
https://www.redirect_url.com/?transactionId=tpEkkmWCsgZFGz9hcj88qeyreXEZY&orderId=tpEkkmWCsgZFGz9hcj88qeyreXEZY

```

Thank you  
I hope that redirect\_url will be develop in sandbox in the future

Hello,

Is there any opportunity to add these 2 features?  
Because it is really not easy to test a failed payment and the redirect url.

Does it exist a guide containing the GET parameters of the redirect url?

Thanks.
