Maximum length possible for new API token

[Rishi Kumar Gupta Tadikamalla]

Hello team Jira, 

As per this article, new Personal access token length is variable. 
 https://support.atlassian.com/atlassian-account/docs/manage-api-tokens-for-your-atlassian-account/

As you suggested in the above link, my script to pass this token to Jira can be a variable length, but we have to define max characters for that field in our application. 

Can you please help me what could be maximum length possible for this new API Personal access token length ??

Given that this token is passed in the HTTP request header and since HTTP doesn't really specify a limit. Then you should go with what most server does in limitation. It typically uses header sizes within 16K more or less. Therefore I would suggest keeping the max character for the API key under 256 characters.
