I'm considering a scheduled script to relay fulfillments to one of our (extremely low tech) 3PLs, high level idea would be to send a single email with a csv of search results (all fulfillments) attached plus a pdf packing slip per fulfillment. Very small numbers so no stress on attachments total file size. I feel like it shouldn't be too difficult using search, email, render and file modules. Just wondering if anyone has any words of warning/gotchas from attempting similar?

No doubt saved me some painful google time in the near future, cheers!

bonus points if you make your integration smart enough to automatically search the search types to detect when it fails

FWIW N/task beats search + file for the writing the CSV to file cabinet piece here I think, wasn't familiar with it....
