How may I to catch a twitter share event. Twitter JS SDK has some method where I may to subscribe to share event, but this event fires just when I clicked share button and even before share popup will be shown. So this callback is unneeded because it fires always when button was clicked, even if I close modal popup.
This relates to the change in Web Intents callback behaviour announced here, and discussed in the linked threads. You’ll have to check whether or not the Tweet was posted to the user’s profile, as there is no way to do this via the Web Intent.
