We've got a working salesforce api implementation that gets and sets properly with a production salesforce account. We've recently come across a user that rather than using their production Salesforce to connect to our implementation, has set up a sandbox for a limited trial.
I personally have a sandbox that I can properly connect to. It is not, however, connected to a production salesforce instance.
I'm wondering if the fact that they have a production salesforce instance that they created the sandbox from will affect the API login to the sandbox.
I'm currently receiving a "your salesforce login is incorrect" even though I am absolutely certain the credentials and security token are correct.
If you need any other information, I'll happily include it.
Thoughts?
