None that I could find.

Short Description and Why It's Useful

Direct pricing sync works quite well, except that the server end does not have access to the current users' token. This pull requests does two parts:

• It includes the users token
• It refreshes clientside, as the server doesn't have access to the users info

This allows for any api server to apply customer or customer group specific pricing without having all the different price groups exposed to the client.
