Measurement Protocol with uid but without cid not received in GA

Question

I have a booking system where a booking can be made: 1. immediately by a customer, or 2. on their behalf by a customer service agent.

For 1, I've had success POSTing an event hit to the Measurement Protocol with a cid and our uid for a "purchase". Initially without the cid , it wasn't working despite the docs saying only one of uid or cid are required.

For 2, which isn't customer initiated, when I don't pass a cid nothing comes through to GA (neither the real-time dashboard or the ecomm report).

Here's the hit for option 1, broken in to lines for easier viewing:

t=event
&v=1
&tid=UA-XXXXXXX-2
&ec=Ecommerce
&ea=Purchase
&ti=176410
&ta=Some+Affiliation
&pa=purchase
&tr=123.45
&pr1id=Repair367
&pr1nm=Something+Replacement
&pr1pr=123.45
&pr1qt=1
&pr1ca=Repair%2FInspection
&pr1ps=1
&cd3=None
&ni=1
&uid=469585

Answer 1

OK, so it turns out this is the case:

• If using cid, your hit will appear in your property's standard view's real-time Event screen (immediately) and ecomm Sales Performance screen (~10mins later for me)
• If using uid and no cid , your hit will appear ONLY in those screens under your property's UserID view.

I'd been looking in the standard view and nothing was appearing as soon as I swapped over to a uid-only hit when it was customer service initiated. So although the docs say only one of either uid or cid are required, it should mention it has a significant affect on where the data is viewable in GA.

Sigh.
