# Connecting to an on-premise Microsoft Dynamics CRM instance

In order to connect to Microsoft CRM Dynamics on Workato, you need to obtain a client ID by registering Microsoft CRM Dynamics App with Active Directory Federation Service. Click here (opens new window) to read more on how to register an on-premise Dynamics app with Active Directory Federation Service.

Remember to extend the refresh token expiration time if required.

# Extending refresh token expiration time

Whenever you connect to a Dynamics app, Workato gets an access token to be able to read and write to your Dynamics instance. This access token is valid until its expiry date. Workato also gets an accompanying refresh token with this access token. Whenever your access token expires, Workato can request for a new access token with the refresh token. Dynamics will check that this refresh token is still valid (i.e. the token has not been revoked), and provide a new pair of access and refresh tokens.

However, refresh tokens have expiry dates as well. If both access token and refresh token expires before Workato requests for new tokens, the Dynamics connection will no longer be valid, and a re-connection is required from the user. When this happens, Workato's requests to Dynamics will get a 400 response. If you are using a Dynamics CRM trigger, this results in your recipe experiencing trigger errors. If you are using a Dynamics CRM action, this results in job errors.

To ensure your recipes run continuously without requiring intervention, extend your refresh token expiration time, or set it to unlimited. You can apply and scope it to an OAuth application instead of applying it to the entire organization.
