Hi @takabayashiy 

If you mean Transfers by Zapier, then currently a Transfer cannot be deleted from the list of transfers.

Can you post screenshots of what you are referring to?

Hi there, @takabayashiy! Thanks for reaching out. 

Great question and Troy is correct, at this time deleting a Transfer isn’t an available feature. You can also see this thread that mentions that. :
 

I hope this helps!
