CTA Button

You can change CTA label and URL on the fly. You need to ensure that there is a CTA already added to the video for the change to reflect.
Firework allows you to modify video properties within any video related custom event. For the list of events see "Video Events"
Example:
document.addEventListener('fw:video:impression', function (event) {
event.detail.actions.video.update(({ videoFactory }) =>
videoFactory((v) =>
v
.actionType('Watch now!')
.actionUrl('https://www.youtube.com/watch?v=dQw4w9WgXcQ')
)
)
})
