We implemented a TikTok campaign for Deutsche Bahn in which TikTok users could create a video using one of six interactive DB filters and generate a 50% discount code for their next train journey. To make this possible, we developed a mechanism that allowed us to generate voucher codes via TikTok filters. In addition, we activated top creators and over 500 micro creators from our database. With success: the TikTok community created over 60,000 videos with the DB filters and generated over 50 million views, so that even the Tagesschau news programme reported on the TikTok ticket.
