Developers are invited to participate in a new community video series on Symbl.ai, where they can share their favorite API and why it's their go-to choice. To do so, they need to record a short video clip of themselves explaining their preference, which should be around 5-10 seconds long and filmed vertically with a minimum resolution of 1080 pixels x 1920 pixels. The clips will then be used to create an interactive video montage that will be shared on the Symbl.ai Slack community and social media channels, allowing participants to showcase their voices and start valuable conversations with other developers. By sharing their favorite API, participants can also win some cool developer swag.
