Data Feeds Visid mapping to mcvisid

[gautamp2021]

We are trying to use the 'visid' field (concatenation of post_visid_high, post_visid_low) in client side for integration.

The post_visid_type field's value in data feeds is 5, indicating that the visid is the 'mid', but when we check the value of mcvisid in our data feeds / the mid field in Adobe debugger, we see that the values are different from the 'visid' field.

Why is that so? Do we need to apply some kind of transformation on the mcvisid for the two values to match?

Dear Gautam,

Can you check the reply from Jantzen?

Hi Arun,

I did have a look at that answer, but unfortunately it did not solve my query.

I am seeing values for post_visid_high, post_visid_low, but their concatenation is not equal to the mcvisid field (mcvisid shows up as Visitor ID in Adobe Debugger).

How do I map the two values & why are they different?

Heya Guys appreciate this feed is from a while ago but did you get an answer to this.  From what I understand if you use the MCVIS service then visid_high & visid_low should be blank but every record in our data has both a visid_high / low which when fed into GCP is transformed into a channel_visitor_id, however every visitor also has an MCVISID but not a single one matches the visitor ID
