This n8n workflow automates the process of creating a Slack channel, inviting a user, posting a welcoming message, and uploading a file to the channel. The workflow is triggered manually by a user, making it suitable for on-demand channel setup or onboarding tasks.
The process begins with a manual trigger, allowing the user to initiate the workflow whenever needed. The first node interacts with Slack to create or select an existing channel named ‘n8n-docs’. Following this, an invitation is sent to a specific user identified by their user ID, ensuring the right people are added to the channel.
Next, the workflow performs an HTTP request to fetch a logo image from an external URL, which is used as an attachment in the subsequent message. Once the image is retrieved, a personalized welcome message is posted in the channel along with the logo image to greet new members.
Finally, a file upload node uploads the logo image directly into the Slack channel, making the content accessible to all members.
This workflow is particularly useful for teams managing multiple Slack channels, onboarding new members efficiently, or automating routine channel setup tasks to improve communication and collaboration workflows.
