Hi @sofauth
Welcome to the Auth0 Community!
To reduce number of used tokens for your tenant I would suggest caching tokens and reuse them. We have a seperate knowledge solutions regarding this problem

And on top of it our community team member created and tested a code snippet for that Caching M2M access token in Actions - #4 by rueben.tiow
Let me know if that solves your issue.
Thanks
