pass additional data to sync url

[jney]

Hi,

Is there a way to add additional data to macros.UserSyncPrivacy to pass it to sync url, I'd like to add so extra id.
thank you

@jney - no, there's no way to define an arbitrary macro to pass arbitrary data to a sync endpoint. Unclear what that even mean. Please note that sync requests don't have much context: there's no auction request, it's in a 3rd party domain so has no access to any type of ID, it doesn't utilize any vendor-specific code.

Please help us understand exactly what you're trying to do.

hi bret, for some reason we need the publisher to pass its api key to the sync system.
it looks like we aren't the only one with the issue https://github.com/prebid/prebid-server/blob/master/static/bidder-info/zeta_global_ssp.yaml#L18

I would recommend changing that requirement to allow the PBS host-company to have the API key rather than having a different key per publisher account in a multi-tenant environment.

If you insist on per-account, a community member will need to contribute the feature. It's not a priority for the core development team.

1. The /cookie_sync endpoint doesn't require the account ID.
2. If the account ID is provided, it will do a lookup to get the account config
3. There's no current place in the account config to put account-specific sync macros

If you want to add this feature, go ahead and add an account config like:

cookie-sync:    // in PBS-Go, use underscore instead of dash
  url-macros:
    bidderAsynckey: abc123

Update the /cookie_sync endpoint to resolve macros in the sync URLs something like

url: https://HOST/redirectuser?apikey={{MACRO:bidderAsynckey}}&gdpr={{.GDPR}}

There are details to work out with this. If someone really wants to build this, we'll help you dot-the-i's and cross-the-t's.

looks like we aren't the only one with the issue

This example is global to the PBS host, not per-account.
