The template needs an image layer named `cocktail-image` and text layers named `title` and `recipe`. Connect Rocket.Chat in **Post the banner in Rocket.Chat** and enter a room ID, `#channel` or `@username` that the connected user can post to. The CocktailDB URL uses public test key `1`, intended for development and education. Review [CocktailDB API access](https://www.thecocktaildb.com/api.php) for your use and change the key in **Prepare the cocktail URL** or the n8n **HTTP Request** node if needed. In n8n, configure Bannerbear and Rocket.Chat credentials, template ID and channel, then activate one format. ## Behavior At 18:00 each Friday, the workflow requests one random cocktail, fills its image, name and instructions into the template, and posts the rendered image as a Rocket.Chat attachment. The schedule starts in UTC; change the timezone for your local Friday evening. The source used the n8n instance timezone. n8n Cron V1 chooses a fixed randomized second within the minute; Open Flow uses the minute boundary. Missing recipe fields, an invalid image URL, request failure or incomplete image stops the run before posting. Open Flow uses Bannerbear’s synchronous endpoint, which can time out after 10 seconds; n8n creates asynchronously and checks up to three times. A timed-out or uncertain image request may already have created an image. A failed or uncertain Rocket.Chat post may already have arrived. Check the services before replaying; no automatic retry or rollback is configured. The HTTP step follows up to 21 redirects with a 30-second timeout per request; Open Flow limits each response to 4 MiB. Inspiration & credits ## Changes to the source * Configure the template and room without private credentials; validate cocktail fields and the completed image before posting, then check the post result. * Use a UTC starting schedule and Bannerbear’s synchronous Action in Open Flow.
