I'm doing some Apple iTunes Connect reporting via the Autoingest tool. It requires that I not only specify login account info, but also a "vendorid". I have no clue what our vendor ID might be. Where can I find such info on Apple's site?
Click on the Sales and Trends section, and your vendor ID will be displayed in the upper-left corner next to your developer name. It should start with an 8.

This number may be a bit harder to find since Apple re-designed iTunes Connect on Mon, Feb 17th, 2014.
Multiple vendors: If you go into the monthly financial section and have multiple vendors a drop down will show up in the upper left with this number.
If you only have one vendor: Download a monthly financial report. The vendor id is the long number at the beginning of the report name before the first underscore.
With the new iTunesConnect, you don't actually have to download a financial report to get the Vendor ID.
Go to "Sales and Trends", then choose "Reports" from the drop-down menu in the top left.
On the next screen, there'll be a drop-down menu for "Vendor". Your name and ID will be shown there.
Apparently the latest version of the Autoingestion script is looking for a 10 digit version of the ID. If you stick two zero's in front of the number it gives you on the Sales and Trends page that will work...
