I would like to use Mattermost together with Nextcloud Deck (https://github.com/nextcloud/deck). The final objective would be to create tasks in Nextcloud Deck by sending a message on Mattermost (assigning the task to a specific person, with a due date, …)
As a first step, I would like to create (from Mattermost) a new card in Nextcloud Deck. There’s an API in Nextcloud Deck (https://deck.readthedocs.io/en/latest/API/#cards). On Mattermost side, I understand that I can use either outgoing webhook or slash command.
As I’m a beginner in this field, what do you advise me? Did anybody already tried something similar?
Thanks for your support!
