Setup Heyzap install tracking using branch
Hi! You need the Branch webhook feature. All you need to do is configure a webhook for the install event, using the Postback URL that Heyzap is providing. Since you’re appending impression_identifier as a query parameter on your link, that data will be captured by Branch and you can pass it back through using a template value. In this case, I believe it should be identity.link_click.query.impression_identifier.
