The App “Universal Announcer” is using data from the XLM-file, which is created when simbrief generates a flightplan. Newly, I noticed that in the XLM-file in the \<api\_params\>- and in the -section the “cpt”-line remains empty, although there is an entry in the simbrief text entries section. Till last week this was working fine. What happened?

Hi, this data is no longer available in v1 of the API.

The developer will need to move to a newer version of the API, which requires them to implement the [Navigraph Authentication flow](https://developers.navigraph.com/docs/authentication/overview). If this is something they are interested in, they should reach out to [dev@navigraph.com](mailto:dev@navigraph.com) for further guidance!

Best regards,
