Hi, how are you?

I'm trying to implement zoho subscriptions api to my server (node js) to read / write new products, plans, etc.

But in my flow, i don't need any user consent... and i have some questions about the implementation.

1) I created a self client appication in zoho developers console, so i could generate a ten minutes valid "code" to exchange for a new token. And when i have a one hour token i need to implement some logic to refresh this token every 1 hour (because the access token is invalidated).

how i can implement this logic?

I need to save the first access token (obtained by manually generated code) in my server code? and then, every time that i want to make a request to zoho subscriptions validate if the token is expired to make a new access token with the refresh token?

do you have any examples of that (maybe in other languages).

thanks for your help!
