Hello and welcome to the Community @Devinder_Singh1!
At this time we have a form to submit for requesting Meta API access. Due to the overwhelming interest in the metadata API we have paused creating new tokens for the time being as we iron out our infrastructure and monitoring. Sorry for the delay, but if you’ve submitted the form we will keep you updated on when we will be creating new metadata API tokens.
Let me know if I can help provide any more information, and if this helped answer your question please mark it as the solution :white_check_mark: .
