Hello,
I am curious to know if Marketo supports flat file integration? tried with Marketo developer and places but no clue around?
Thanks,
What do you mean by "integration"?
Importing leads from a flat (CSV) file: sure, via GUI and API.
Sending directly to a flat file of addresses: no.
Yes, if you want to auto import flat files, go use Boomi.
Otherwise, use the list import process.
