The final step of the certification process is submitting a testimonial video that features one project idea. We know that most folks are not professional video editors so don't get caught up in the technical aspects. Just submit a short video (1-3 minutes) where you introduce yourself, tell us why you love using ThingLink, and share a favorite project idea. You can even upload the video to ThingLink and add tags if you want, but it's not necessary. Check out the example below to get an idea.
