@mefjush - I'll go ahead and merge this, but I'm asking Adhese to make these two changes:

1. First, update your server-side adapter to support both data and targets. It's a significant annoyance to publishers when the client-side and server-side adapters don't agree on parameter names because then they can't use the s2s testing module. It should be easy for your server-side adapter to listen for data and just treat is as targets.
2. You're missing a lot of metadata in this docs file. Please look at https://docs.prebid.org/dev-docs/bidder-adaptor.html#submitting-your-adapter and supply all the missing metadata. e.g.

dsa_supported: true/false
usp_supported: true/false
coppa_supported: true/false
gpp_sids: tcfeu, tcfca, usnat, usstate_all, usp
schain_supported: true/false
dchain_supported: true/false
userId: (list of supported vendors)
media_types: banner, video, native
safeframes_ok: true/false
deals_supported: true/false
floors_supported: true/false
fpd_supported: true/false
prebid_member: true/false
multiformat_supported: will-bid-on-any, will-bid-on-one, will-not-bid
ortb_blocking_supported: true/partial/false
privacy_sandbox: no or comma separated list of `paapi`, `topics`
