This module is a temporary measure for publishers running Prebid.js 9.0+ and using the AppNexus PSP endpoint through their Prebid.js setup. Please ensure to include this module in your builds of Prebid.js 9.0+, otherwise requests to PSP may not complete successfully.
This module replicates certain functionality that was previously stored in the appnexusBidAdapter.js file within a function named transformBidParams.
This transformBidParams was a standard function in all adapters, which helped to change/modify the params and their values to a format that matched the bidder's request structure on the server-side endpoint. In Prebid.js 9.0, this standard function was removed in all adapter files, so that the whole client-side file (eg appnexusBidAdapter.js) wouldn't have to be included in a prebid.js build file that was meant for server-side bidders.
