Custom Fields in Marketo - How to tell?

Best way is to document the list from a fresh install.  This is a recent issue with more modules of Marketo creating additional fields.  

Ok, well, lets just say there is no documentation from the install, any other suggestions on how to pull this?

Looks like most Marketo fields have "mkto" or "marketo" in the name, but its not consistent.  Salesforce also indicates the install source of fields, the date and source can provide some clues.

This isn't a very good way because you have to check each field but custom field type can be changed whiel out of the field's type are fixed.
Select the field -> Field Actions -> Change Type

Thanks Hitoshi - this seems to be a solution - although a tedious one.

I think it's best practise to use a prefix for the custom fields you add. You could use "TPP_" in front of each field name.

I actually mean "TPG_", but overlooked the fact that you have it mentioned as The Pedowitz Proup in your Marketo Community profile.

Thanks Diederik. This issue not on a new installation or new fields - it is finding out on a previous fields where there are no naming conventions.

Thanks,

if there are in use (not hidden) they are all located at the bottom of the Lead Info tab...

Hi,

This article may help - it lists the default Marketo fields in the company and lead tabs of a record. You can assume any outside of these are custom or synced from your CRM.
