A common question after authenticating a user with MYOB and receiving the access_tokens and refresh_tokesn is "how long will the tokens last?"
The access_token has a lifetime of 1200seconds from the time it was generated. That is, it will last 20 minutes before it expires and you need a new one.
To get a new one, simply use the refresh_token in a call to the MYOB authentication server. For full details on doing this, visit our guide to refreshing a token.
The refresh_token has a lifetime. It can last for up to 1 week*¹ from the time it was generated. This gives you peace of mind that when your application needs to communicate with your users MYOB company file, you can use the refresh_token to get a fresh access_token and fetch/update the data you need.
Each time you use a refresh_token the authentication server will respond with a payload that looks like this:
We always recommend updating the stored refresh_token because it can change, and this is where the MYOB authentication server would give you a fresh one.
