***If a client has an Acumatica with a version of (2024R1 or Newer) then they can configure Acumatica to no longer require a re-authorization of 3rd party applications every 30 days.***

  • To configure this setting in Acumatica, the client will need to log into Acumatica and go to (Connected Applications)
  • Once in (Connected Applications) the client will need to find the Client ID for the Assignar Integration
  • Once selected, please change the (Mode) under (Refresh Tokens) to (Sliding Expiration)
  • Once (Sliding Expiration) is selected, please select 15 for the (Sliding Lifetime) and check the box next to (Infinite) 

***If a client is on an older version then 2024R1, then they will be required by Acumatica to re-authenticate 3rd party integrations every 30 days.***If you are looking to change Acumatica tenants, please contact the Assignar Support Team***

  • Enter the (Tenant ID) of your Acumatica instance, as well as the (Instance URL).
    • The (Instance URL) is the website that you go to log in, e.g. “” (this may be saved from your last authentication)
  • Click Save
  • The webpage will then ask you to sign into Acumatica. This is where you will need to login with your (Assignar Integration User) login information. Do not sign in with any Acumatica user, this Acumatica login is only for the (Assignar Integration User). Failure to authenticate with the (Assignar Integration User) will result in the integration not having the correct permissions to push and pull data between the two systems.
  • Once you click (Sign In) you may be prompted to grant permission to the integration
    • Select (Yes), Allow permissions for the default options (Access to Web Services API, Offline Access, and Remember my decision) 
  • Once the authentication has been successfully renewed, select Finish
  • Now, make sure that the Enable toggle at the top of the screen is toggled to the right so that your integration is enabled
