TikTok Spark campaigns are available for 7, 30 or 60 days. This means that the brand can boost a video for one of the 3 time options. Once the content you create is approved by the brand, you publish the video and generate a code which you then pass on to the brand in the chat. Once they get the code, the deal is completed. The funds are transferred into your Insense wallet.
The duration of the TikTok Spark campaign is always specified in the brief. When you generate a code for the brand, make sure you choose the duration that matches the one from the brief. Once the time expires, boosting is automatically deactivated by TikTok.
