In this document, you’ll find a brief description of the new Multibet widget front-end structure. The multibet widget product is designed to allow bettors to place several bets related to a fixture in pre-match or in-play. Initially, American Football and Football (Soccer) are supported, work is in progress to support new sports.

It is intended for bookmakers to implement on their websites offering their users a range of configurable markets per event according to their needs. The Widget allows different customizations such as colors and fonts, allowing our customers to use their brand properties offering their end users a seamless experience on their site.

Multibet Widget Integration

Our customers should embed the Multibet Widget through an iframe. When a player makes his choice and requests a bet, the Multibet Widget will call the customer’s bet slip with all the required data to populate it with the selection details.

Customers already integrated with other Fan Engagement products such as betting widgets, Game Trackers, and Scoreboards can re-use the existing iframe implementation for the Multibet Widget.

Reverse Proxy

Customers should setup a reverse proxy to protect from unauthorized access and malicious traffic. The detailed information can be found in Authenticating User-Session Using a Proxy Service

Embedding a Multibet Widget

How do I embed a Multibet widget under a specific fixture? 

The Multibet Widget offered by Genius Sports is fixture-specific and does not accommodate an event viewer and selector page, therefore it should be embedded under a specific fixture within the Sportsbook page. Using a URL parameter fixtureId which is expecting Genius Sports Fixture Id as a value:

https://gsm-widgets.betstream.betgenius.com/multibet?fixtureId=[fixtureID]&productName=[clientName]&culture=es-ES

Other parameters will be required like:

  • Product Name: this is the customer name given by Genius.

  • Culture: is the parameter related to the language preferred.

<iframe src="https://gsm-widgets.betstream.betgenius.com/multibet?fixtureId=[fixtureID]&productName=[clientName]&culture=es-ES" width="1180" height="622"></iframe>

Supported minimum sizes for Widget: 300px/560px

 

Event listener

The customer must have a listener to receive the events that the Multibet Widget will send when the player makes his bet in the Add to betslip action.

The following is an example of the structure of these events:

{     "command": "addToBetslip",     "sportsbookFixtureId": "56789",     "marketId": "100120022",     "sportsbookMarketId": "1234567",     "sportsbookMarketContext": "ABCDE",     "decimalPrice": "1.66" }

  • sportsbookFixtureId - customer fixture ID

  • marketId - Genius Sports market ID

  • sportsbookMarketId - customer market ID

  • sportsbookMarketContext - customer market context. This field will be populated only if customer provided it in UpdategramResponse

  • decimalPrice - the price that was displayed in the Multibet widget when punter pressed "Add to betslip" button. This value should NOT be used for bet acceptance

Customers can easily customize the look of the Multibet Widget. More details are available on Widget Customization
