 1. The s2sConfig.bidders array contains 'tripleliftVideo' telling Prebid.js to direct bids for that code to the server
 1. Finally, the extPrebid.aliases line tells Prebid Server to route the 'tripleliftVideo' biddercode to the 'triplelift' server-side adapter.

+### Map modules to Global Vendor IDs
+
+Prebid modules sometimes need to know the [IAB Global Vendor List](https://iabeurope.eu/tcf-for-vendors/) (GVL) ID associated with a bidder alias or other module. The optional `gvlMapping` object lets publishers specify these IDs or override the ones declared by the module itself.
+
+```javascript
+pbjs.setConfig({
+  gvlMapping: {
+    appnexus: 4,
+    someModule: 123
+  }
+});
+```
+
+Prebid Server uses this mapping when it sends `ext.prebid.aliasgvlids` for bidder aliases, and the [TCF Control Module](/dev-docs/modules/tcfControl.html) references it when enforcing consent.
