Description

what is the best way to get the EIDS module that has been used in the auction of PBJs?
I tried to use pbjs.getUserIdsAsEids() but I got a lot of sources and I don't know which module has supplied what
so I tried the pbjs.getUserIds() unfortunately the structure of the result is not the same
for example
{ foo: 'abc', boo: [], zoo: { ext: 'some-string', uid: 'some-string' } }

There's no map from module name to eids source that I'm aware of, but you should likely form one for the modules you work with. They are meant to be easy to recognize, but there's certainly some exceptions.

This is available at https://docs.prebid.org/dev-docs/modules/userId.html#prebidjs-adapters

We should add it to each userid page

Discussed today in docs PMC

• add a new meta data field: eidsource
• generate modules table dynamically
• display the meta data field on each user id page
• add also a meta data field: bidRequest.userId
• add gvl_id (optional)
• add gpp_sids ? needs more discussion
