Extra info when creating a Channel via API

Hi, I’m new here. If someone can help, I would be very happy.

I’m using the API to create new channels on Mattermost. Everything is ok, but, I would like to have an option to save some external ID field to link this channel with future linkage.
Is it possible? Like an extra field to have the ID of the origin link for the future communications…


No help? :pensive:

Please, any advise?
