Twilio is hosting a new developer contest where participants are encouraged to build click-to-call integrations with various platforms such as WordPress, Typepad, Zendesk, Twitter, Salesforce, Craigslist or Yelp. The goal of the contest is to create innovative and practical solutions that showcase how click-to-call functionality can enhance user experience. Participants have until 11:59pm on February 7th to submit their projects, and are encouraged to share a screencast explaining how to use their integration as an added bonus. The contest aims to provide valuable resources and inspiration for developers looking to build communications and digital engagement experiences.
