I am working on a Marketo to Marketo migration for a client and am working to clean up their list of fields. Their previous instance has 280 fields, a lot of which are not being used or are redundant and do not need to be moved to their new instance. It would be helpful as I organize my list to get a quick list of the standard Marketo fields as a starting place so that I know which ones I have control over changing. I've poked around in the Help articles but can't seem to locate one.
I am also hoping someone could give me a quick tutorial on Rest and Soap API. I exported the field list, and there are columns for each API name. Hoping there are clues in the field naming that will let me know if the field was came from a Salesforce integration or integration with another tool.
Any help would be much appreciated!
