How many ID Sync Calls Hit should be triggered after user authenticate?

[Vijayakumar_Raju_DM]

Hello All,

We would like to understand on how many time ID sync calls should be triggered after user logged in in/authenticated. Whether the customer ID should be triggered only one time when user logged in and one more time hits when the user is logged out.

Or, this ID sync call should be triggered continuously until the user logged out.

Below are the example we are trying to explain our issue.

Step 1 - When anonymous user browsed the website, then the visitor id seems to be below

d_visid_ver: 2.4.0
d_fieldgroup: MC
d_rtbd: json
d_ver: 2
d_orgid: XXXXXX@AdobeOrg
d_nsid: 0
ts: 1576762828232

and in another event along with the same request.

d_visid_ver: 2.4.0
d_fieldgroup: A
mcorgid: 32B2238B555215F50A4C98A4@AdobeOrg
mid: 57248373193361564013351788557209327809
ts: 1576762828890

Step 2 - When the user is authenticated then the below calls has been triggered along with customer ID (i.e.) ID Sync call.

d_visid_ver: 2.4.0
d_fieldgroup: AAM
d_rtbd: json
d_ver: 2
d_orgid: XXXXXX@AdobeOrg
d_nsid: 0
d_mid: 57248373193361564013351788557209327809
d_blob: 6G1ynYcLPuiQxYZrsz_pkqfLG9yMXBpb2zX5dvJdYQJzPXImdj0y
d_cid_ic: customer_id
123456789
1
ts: 1576763292778

Step 3 - When the user is logged out then the below calls has been triggere

dd_visid_ver: 2.4.0
d_fieldgroup: AAM
d_rtbd: json
d_ver: 2
d_orgid: XXXXXX@AdobeOrg
d_nsid: 0
d_mid: 57248373193361564013351788557209327809
d_blob: 6G1ynYcLPuiQxYZrsz_pkqfLG9yMXBpb2zX5dvJdYQJzPXImdj0y
d_cid_ic: customer_id
123456789
2
ts: 1576763292778

Here is our query, this second steps call mentioned above is this ID sync call hits should be triggered every time across the user journey until the user logged out or its should triggered only one time at the starting call when user logged in????

Hope you understand my question !

Thanks,

Vijay
