Hello,
Will this add-on check for duplicate records?
So, if a record already exists then update it. If not, then add it.
My client uses Ringlead for this now. Won’t that be necessary with this plugin?

And why there are no installations of this plugin yet? Is it new?

Thanks in advance, Sandra

FROM SALESFORCE: As of April 20, 2018, any API calls made to the https://www.salesforce.com endpoint will need to be changed to use the https://login.salesforce.com endpoint. If no action is taken, the API will no longer function, and your API login calls will result in a “404 (Page Not Found)” error. This only applies to API traffic; logging in from a browser by clicking “login” will still work.

I’m so glad you have taken over a Gravity Forms Salesforce plugin. Do you plan to update to account for the new API URL? I believe your plugin currently uses the old www.

Thanks!
