How to fetch access token into multiple pages

Hello team,
i want to know that how can i access generated access token to multiple pages

It is advisable to utilize the same access token across multiple pages. It’s not necessary to create a new token for each page. The access token remains valid for an entire day and will expire the next day at 3:30 AM. For more information, refer to Get Token | Upstox Developer API.

ohh understand , i was keeping the auth code instead of access token i will work with access token and generate values.
thank you very much
