n8n Workflow: Outbound Messaging with Baserow and Custom API

This n8n workflow provides a flexible framework for initiating outbound messaging based on data stored in Baserow, with the ability to integrate with a custom messaging API. It acts as a central hub for triggering messages and logging their status.

What it does

This workflow is designed to:

1. Receive Webhook Triggers: It starts by listening for incoming webhook calls, which can be used to initiate the messaging process.
2. Conditional Logic: It includes a "Switch" node, indicating that the workflow can branch its execution based on specific conditions from the incoming data. This allows for different actions to be taken depending on the message type, recipient, or other parameters.
3. Interact with Baserow: It includes a Baserow node, suggesting that it can either retrieve data from Baserow (e.g., recipient lists, message templates) or update records in Baserow (e.g., log message status, update contact information).
4. Send HTTP Requests: It can make HTTP requests to an external API (likely a messaging service like WhatsApp, SMS, or email provider) to send outbound messages.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running instance of n8n.
• Baserow Account: An active Baserow account with a database and table configured to store relevant messaging data (e.g., recipients, message content, status).
• Baserow API Token: An API token for your Baserow account to allow n8n to interact with it.
• Messaging API Endpoint: Access to a custom messaging API (e.g., a WhatsApp API like "WASenderAPI" as hinted by the directory name, or any other SMS/email gateway) that can receive HTTP requests to send messages.
• Messaging API Credentials: Any necessary API keys, tokens, or other credentials for your chosen messaging API.

Setup/Usage

1. Import the Workflow:
   • Download the provided JSON file.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click the three dots in the top right corner and select "Import from JSON".
   • Paste the JSON content or upload the file.
2. Configure Credentials:
   • Baserow: Locate the "Baserow" node and configure your Baserow API credentials. You will need to provide your Baserow API token and potentially the base URL if you are self-hosting Baserow.
   • HTTP Request: Locate the "HTTP Request" node. Configure it with the endpoint URL, method (e.g., POST), headers (e.g., Authorization with your API key), and body structure required by your messaging API.
3. Configure Webhook:
   • Locate the "Webhook" node. After saving the workflow, activate it to get its unique URL. This URL is what you will call from an external system to trigger the workflow.
4. Configure Switch Logic:
   • Locate the "Switch" node. Define the conditions that will determine the flow of your messages. For example, you might check a messageType field from the incoming webhook data to send different types of messages or target different APIs.
5. Customize Baserow Interaction:
   • Adjust the "Baserow" node to perform the desired operations, such as:
     • Get All records from a specific table to fetch recipients.
     • Update a record to log the status of a sent message.
     • Create a new record to log outbound message attempts.
6. Customize HTTP Request:
   • Modify the "HTTP Request" node's body to send the correct payload to your messaging API, mapping data from previous nodes (e.g., recipient number, message text) into the API request.
7. Activate the Workflow: Once configured, activate the workflow. You can then trigger it by sending an HTTP POST request to the Webhook URL.

Note: The "No Operation, do nothing" and "Sticky Note" nodes are placeholders or for documentation within n8n and do not require specific configuration for the workflow's core logic. The "Switch" node currently has no connections, implying that the conditional logic needs to be fully defined and connected to subsequent actions (e.g., different HTTP requests or Baserow updates based on the condition).
