Reconfiguring integrations via API

I have some devices that use an access code, and for reasons outside my control the code occasionally changes and I’d like to automate reconfiguring the integration for several devices. I have some experience using the http api endpoints, and I see this integration uses config flow.

My question is, do the configflow “handler” values ever change for a specific device? repeated “configure” button clicks look like they don’t, but this isn’t something mentioned in the flow docs. if it does ever change I assume the new value would be in the response for the last step? or maybe each step and I should be watching for that?
