Type of change

New bidder adapter
Does this change affect user-facing APIs or examples documented on http://prebid.org?

Yes - docs PR here: prebid/prebid.github.io#6576

Description of change

New bidder adapter: Engerio

Contact e-mail: info@thinkeasy.cz or david@thinkeasy.cz

Test parameters for validating bids:

{
  "bidder": "engerio",
  "params": {
    "adUnitCode": "example-test"
  }
}

and dimensions:

"banner": {
        "w": 300,
        "h": 300,
        "format": [
          {
            "w": 300,
            "h": 300
          }
        ]
      }

Ad slot scope

Engerio slot resolution is host-scoped. If you require a live test, these values should be used:

site:page   = 'https://example.com/article'
site:domain = 'example.com'

If tested with a different page URL/host, the auction may return no bid even with a valid adUnitCode.

Example gist

I'm attaching a gist that shows a testing request and response, if useful.

Whoa there partner! This project is migrating to typescript. Consider changing the new JS files to TS, with well-defined types for what interacts with the prebid public API (for example: bid params and configuration). Thanks!

+    const bidRequest = {
+      id: generateUUID(),
+      imp: imps,
+      site: {
+        page: page || undefined,
+        domain: domain || undefined,
+      },
+    };


Preserve ORTB consent fields in auction requests

When consent/FPD modules populate bidderRequest.ortb2 (for example regs.ext.gdpr and user.ext.consent from TCF consent management), this OpenRTB request drops everything except device.ua and hand-built site fields. In GDPR or other privacy-regulated traffic, Engerio's server receives the auction without the consent/regs data it needs to enforce those signals; build the request from/merge bidderRequest.ortb2 instead of replacing it with this minimal object.

Useful? React with 👍 / 👎.

+    if (!bid.params?.adUnitCode) {
+      logWarn(`${BIDDER_CODE}: bid is missing required params.adUnitCode`);
+      return false;


Accept the conventional adUnitCode fallback

For any publisher whose Engerio slot ID is the same as the Prebid adUnit.code, this rejects the bid unless they duplicate that value in params.adUnitCode. Bidder params are supposed to override conventional request fields rather than be required in place of them, so this causes otherwise valid banner ad units to no-bid; allow bid.adUnitCode as the default and use params.adUnitCode only as an override.

Useful? React with 👍 / 👎.

adapters are required to type the public interface with a d.ts import or swtich the main adatper file to ts

Should be typed/resolved now. Sorry about that.
