Reported by your backend

There is no browser here to run a pixel, so your own server reports the audience. It already knows who signed in. Send one scrambled identifier per unique person per billing period and the meter does the rest — repeats are free, so retries and replays never move the count.

Setting it up

1. 01 Register the channel in API Management and copy the server key.
2. 02 State roughly how many people use it each month. It is not what you are billed on; the licence requires the figure on record.
3. 03 Hash each internal user id with a secret only you hold.
4. 04 Post it once per person per billing period, then mark them done.
5. 05 Show the FXMacroData attribution wherever the data appears.

One call per person per month
