What is the maximum number of characters a Square API Access Token for production for an account can be?

What is the maximum number of characters a Square API Access Token for production for an account can be? The minimum would be nice too, but doesn’t matter as much of course.

Sadly, I cannot find any information on this page: https://developer.squareup.com/docs/build-basics/access-tokens

Thanks,

Shardul

This info is in the tech ref, currently. You can see it on ObtainToken's page:

A valid OAuth access token. OAuth access tokens are 64 bytes long.

Please let me know if you have additional questions or concerns!
