Connect JotForm to Salesforce sandbox instance

I am having the same issue. I tried to work around the redirection to a production URL (login.salesforce.com) by simply changing it in the address bar, but that leads to a failed authentication. There really needs to be a way to specify whether we want this connection to be a production instance or a sandbox instance. I understand that we can setup a dev org, but it seems silly to spin up a new org and then migrate our metadata to a new environment just to test this connection. The beauty of a Salesforce sandbox is that it copies all of the metadata (and often some or all of the data) so that we can test a connection like this in context (does the creation of this record hit automation triggers, do I have validation rules that this will break, etc.). Without the ability to do this, no admin will want to use this connection. Please look at the legacy connector, it has a slider that allows you to choose whether you want to connect to a sandbox or not.

Unfortunately the option to connect the form to Salesforce sandbox is not supported yet.

I have now submitted a feature request ticket to our developers for the option to integrate with Salesforce using sandbox instance.

We cannot provide you any time frame as to when this will be available, but we will notify you here and in your email for any news/updates on the status.
