REST API - Invalid token

[Anonymous]

Hello - 

I have recently started dabbling with Marketo REST API and I keep running into invalid token issue.
The token works fine initially and I get valid response back (with accurate data). However, after I run the code a few times, I run into the following message..

[{"code":"601","message":"Access token invalid"}]}

Would be great help to understand why the token becomes invalid after working initially.

Thanks for the help.

Thanks Murtza. Very helpful.

If you generate token from UI, token expires in an hour. If you generate token from API via auth endpoint, it expires in 24 hours

Auth endpoint:

This answer is not correct.  Token life is always 1 hour.

Thanks Murtza.
Do you know under what conditions the token expires. I am noticing that it expires after a few calls and I do not think regenrating tokens on a frequent basis is a very scalable solution.

This has to do it with the access token expiring. To fix the error, regenerate the token.
