Random Cocktail to Mattermost

Fetch a random cocktail and post its instructions, glass and image to a Mattermost channel.

Setup

Connect Mattermost with permission to post in the intended channel. Deploy the webhook, then POST JSON with the target channel ID, for example {"channel_id":"YOUR_MATTERMOST_CHANNEL_ID"}. In n8n, select Mattermost credentials and activate the workflow.

The webhook is unauthenticated, as in the source. Anyone who knows its URL can select a channel accessible to the connected account; protect the URL and limit the account’s permissions.

Behavior

Each accepted request fetches one random drink from TheCocktailDB and sends its name, instructions and glass in a Mattermost message, with the drink image as an attachment. A failed lookup or post stops the run; an uncertain post may already have arrived. Repeating a request may choose another drink and create another message. Open Flow checks the required response fields before posting; n8n uses the returned fields directly.

Changes to the source

• Replace the original webhook path and credential with setup.
• Preserve the dynamic channel, random lookup, message and image. Open Flow validates the required fields.
