Prestitial Format ​

This guide details the implementation of the Prestitial Placement using the Missena bidder.

Prerequisites ​

  • Prebid.js integration
  • Valid Missena API key from your account manager

Implementation Steps ​

Prestitial Placement Implementation ​

javascript
var AD_UNIT_CODE = "PASTE YOUR GPT PLACEMENT";
var PUBLISHER_MISSENA_TOKEN = "PUT YOUR MISSENA API KEY HERE";

var missenaAdUnit = {
    code: AD_UNIT_CODE,
    mediaTypes: { banner: { sizes: [[1, 1]] } },
    bids: [
        {
            bidder: "missena",
            params: {
                apiKey: PUBLISHER_MISSENA_TOKEN,
                placement: "prestitial",  // Specifies prestitial placement
            },
        },
    ],
};

var adUnits = [missenaAdUnit];

Key Configuration Points ​

  1. Placement Type: The placement: "prestitial" parameter specifically configures this as a prestitial format.

  2. Size Configuration: The implementation uses a 1x1 size specification for the banner media type.

  3. Ad Unit Code: Make sure to replace AD_UNIT_CODE with your actual GPT placement code.

  4. API Token: Replace PUBLISHER_MISSENA_TOKEN with your unique Missena API key.

Important Notes ​

  1. SafeFrame Configuration: Ensure your prebid creatives are not SafeFrame enabled. The "Serve into a SafeFrame" option in your GAM creative should be unchecked.

  2. Media Types: The implementation uses the banner media type with a 1x1 size specification.

  3. Timing: The prestitial ad appears before the main content loads, so proper implementation timing is crucial.

Validation Checklist ​

  • [ ] Prebid.js is properly configured
  • [ ] Missena API key is correctly set
  • [ ] Prestitial placement parameter is specified
  • [ ] SafeFrame is disabled for the creative
  • [ ] Ad unit size is set to 1x1
  • [ ] GPT placement code is correctly inserted

Implementation Differences from Other Formats ​

  1. Uses a prestitial-specific placement parameter
  2. Appears before main content loads
  3. Full-screen presentation
  4. Specific placement-type configuration in the params

Troubleshooting ​

If the implementation is not working as expected, verify:

  1. The Missena API key is correct
  2. The placement parameter is set to "prestitial"
  3. The GPT placement code matches your ad server setup
  4. Media types and sizes are properly configured
  5. Prebid.js is loaded and initialized correctly
