Capturing multiple user inputs in n8n workflow with WhatsApp API integration?

Hey folks! I’m a newbie to n8n and I’m stuck on something. I’ve got this workflow set up where users send messages through WhatsApp. It’s working fine for the first message, but I can’t figure out how to grab the second response from the user. Here’s what I’ve got so far:

  1. User sends a WhatsApp message
  2. Webhook catches it
  3. Code node cleans up the data
  4. Switch node picks what to do based on user’s choice
  5. WhatsApp sends more options

I’ve tried a few things like using another webhook and messing with the Meta API, but no luck. Anyone know how to make this work? I really need to capture that second response!

Here’s a bit of what the data looks like:

{
  "messaging_product": "whatsapp",
  "contacts": [
    {
      "input": "user_input",
      "wa_id": "user_id"
    }
  ],
  "messages": [
    {
      "id": "message_id_here"
    }
  ]
}

Any help would be awesome! Thanks!

hey there! i’ve run into this too. have you tried using the ‘wait’ node? it’s pretty handy for this kinda thing. you can set it up to pause the workflow for a bit, giving the user time to respond. then use a ‘function’ node to check for new messages. it’s not perfect, but it works pretty well for me. good luck with your project!

Having worked extensively with n8n and WhatsApp integrations, I can offer some insights. The challenge you’re facing is common when dealing with multi-step interactions. One effective approach is to utilize n8n’s ‘Set’ node in combination with a ‘Wait’ node.

After processing the initial message, use the ‘Set’ node to store the user’s ID and current interaction state. Then, employ the ‘Wait’ node to pause the workflow, allowing time for the user’s next response. When the subsequent message arrives, use a ‘Function’ node to retrieve the stored state and process accordingly.

This method maintains conversation context without relying on multiple webhooks. It’s crucial to implement proper error handling and timeout mechanisms to ensure robustness. Also, consider using a database for state management if dealing with a high volume of concurrent interactions.

Remember, thorough testing is key when implementing such stateful workflows, especially with the nuances of the WhatsApp API.

I’ve been in a similar situation with n8n and WhatsApp integration. The key is to implement a stateful approach using n8n’s built-in features. Here’s what worked for me:

  1. After the initial message, store the user’s ID and expected next action in a database or n8n’s internal storage.

  2. Use a ‘Wait’ node to keep the workflow open for a set time period.

  3. When the next message comes in, use a ‘Function’ node to check if it matches the expected action for that user ID.

  4. If it matches, process the second response and continue the workflow. If not, handle it as a new interaction.

This approach lets you maintain context between messages without relying on multiple webhooks. It took some trial and error, but it’s been pretty robust for our use case. Just make sure to handle timeouts and unexpected inputs gracefully. Good luck with your project!
