Hi @Lucas_Reis_Lacerda 👋 Welcome to the community 🎉

According to Slack’s [knowledgebase](https://api.slack.com/authentication/rotation), your token will expire every 12 hours only if you use token rotation. Otherwise, the token will never expire. 🙇‍♂️ So you may need to change this setting if this isn’t desired.
