Static Contact List ID's

We’ve created several static contact lists we are using for syncronizing data. The lists are vusing the api, and action is taken to sync the new data with the other systems.

The problem I’m having, is the listId’s don’t apear to remain constant. I don’t understand how these ID’s could change. My application uses the listId to retrieve the contacts associated with that list.

How can the List Id change, and what can I do to have a constant identifier for retrieving lists via the api?

Hey @PaulSwany

This id should not change.

Per the documentation:

"listId": 1,
 // Integer, read-only; The unique ID of the list. This ID will not change, and should always be used to reference the list.

Are you able to contact support as the Community would be unable to address this

I realize the difference was between test and production. Would love a way to syncronize those environments.
