SalesForce Integration: How to Authenticate salesforce sandbox?

I am trying to connect salesforce but its not giving me the option for production or sandbox. It just automatically goes to production login. Is there a way for me to choose?

Hi,

Unfortunately, currently it is not possible to connect JotForm to the SalesForce Sandbox instance.
I have forwarded this to our developers as a feature request. Though we cannot provide an estimation for the implementation, rest assured that we will inform about any updates as soon as possible, and notify you on this ticket.

Meanwhile, please let us know if there is anything else we can assist you with.

Best Regards,
