Creating Your First Workflow
Now that you have n8n set up, let’s create your first workflow. For this example, we’ll set up a simple workflow that sends a notification from a Google Sheets entry to Slack.
Step 1: Add a Trigger Node
Start by adding a trigger node that will initiate the workflow. For our example:
- Click on the “+” icon to add a node.
- Search and select the “Google Sheets” trigger node.
- Connect your Google account and choose the spreadsheet that contains the data.
Step 2: Configure the Data Retrieval
Set the node to trigger when a new row is added or modified in your Google Sheet. You’ll also want to specify which columns to watch for changes.
Step 3: Add an Action Node
Next, add an action node to send a message to Slack:
- Add another node by clicking on the “+” icon.
- Search for the “Slack” node and select it.
- Connect your Slack account and choose the channel where you want to send the message.
Step 4: Map Data Between Nodes
Link the output of the Google Sheets node to the input of the Slack node by dragging from one to the other. Customize the message content in the Slack node using information from the Google Sheets trigger.
Step 5: Test Your Workflow
With your workflow set up, it’s time to test it. Add a new entry to your Google Sheet and check if a message is sent to your designated Slack channel.
