Adding a parameter to a Facebook Instant Games URL, to access it later in the game

We would like to add a parameter to our InstantGame link http://m.me/PageTitle?game=GameTitle&PARAMETER=VALUE, which we want to read out again later e.g. for campaign tracking.

We found something here, but it doesn't seem to work on instant games. https://developers.facebook.com/docs/games/gamesonfacebook/hosting#queryparams

Can you give me a hint how to add a parameter to the URL, which I can read later again in the instant game iFrame?

Solution

  • The m.me link supports a ref param that will be passed to your webhook in the messaging_optins and messaging_referrals event.
