Maximum number refreshes for access tokens

[Sagar Ganapaneni]

Hi, I have did some research but could not find the answer. If want to use the refresh token for a given client id/secrete across multiple programs, as I will be requesting for many access tokens in this case.

would like to limitations on number of refreshes that can be made in day and how does requesting for a new access code by one of the programs effects the validity of access token requested previously by other program. 

Thank you,

Sagar

Hi Sagar,

There is currently a limit of 25 refresh tokens per user account per client. If the limit is reached, creating a new token automatically invalidates the oldest token without warning. If you need to authorize multiple programs, one workaround is to limit the number of clients that you authorize per user account to 15 or 20. If you are a Google Apps admin, you can create additional admin users and use them to authorize some of the clients. Please check out Using OAuth 2.0 to Access Google APIs guide for more details.

Thanks,
