Then, select the connected WhatsApp number on Wassenger you want to trigger the event from and go back to your canvas

3. Connect the Advanced AI node

Now we need to connect the node that will allow us to build autonomous agents, summarize or search documents

Next

And a window like this will show up

We will leave this for now to get back to our canvas to add our Open AI node, where the magic happens!

4. Connect the OpenAI chat Model

A window like this will open, and we will insert our OpenAI credentials

Create an OpenAI account and find your credentials here

Then add it to Flows

5. Add the memory node

The Memory node allows an AI model to remember and reference past interactions with it, and no credentials are required since it is stored within Flows

Extend the ‘Context Window Length’ to 10

6. Test your first message

Now, we will click on ‘Test step’ on Flows to retrieve the given data from Wassenger and complete the whole process for the automation:

After that, you can try sending a message to your WhatsApp number from another available number.

Then your Flows node will receive your message and contact information that we will use to configure the rest of the workflow

8. Configure the AI Agent with the dynamic retrieved data

Open the AI Agent node we added previously

Then

  1. Select the Source for Prompt (User Message) as define below
  2. Use the ‘body’ field to reference the incoming message within the Prompt so that Wassenger always references the correct data. (Drag the element onto the input.)

If you can’t see the data tree, clickExecute previous nodes and send a new message to your WhatsApp number.

Now that we have completed our AI agent configuration, let’s see the Memory node

9. Add the Wassenger Message Response Node

Now, we will add the node that will send the AI-created message to your end WhatsApp customers

Select ‘Send a Text Message

And a window like this will show up

Then, we can click on ‘Execute previous nodes** to show the message information again and proceed as follows

  1. Select the number ID provided by Wassenger to determine the number used to send the AI response
  2. The target phone number we are sending the AI-generated response
  3. The output message generated by our OpenAI node, based on the question we received from the customer

🎉 You’re All Set to Launch Your AI ChatBot!

Now that everything’s in place, you can see your chatbot in action. For example:
