Looking for assistance in setting up Tealium for Salesforce. I followed the instructions here but what is missing is the required steps on the Salesforce side. Apparently you need to create a dev account that you can test the code on before being able to push it to production. In addition you need to create and run unit tests within a dev sandbox but due to my limited Salesforce dev knowledge I am unsure how to set everything up. Any assistance would be greatly appreciated.
