Hi Anurag,
Thank you for reaching out to our API support team.
By "one central ad account" could you be referring to a top level MCC / manager account? If yes, you can refer to this
guide on how to link client accounts to MCC / manager accounts.
For campaign management in your Google Ads client accounts, including creating its ad groups, you may start by referring to this
guide. As for audience management, you may refer
here and also to the
customer match guide.
I hope this helps.
Best regards,
