Basic Text Responses

To build a basic text response for your WhatsApp chatbot, we use Default Text Response from the Dialogflow. We can create variants for a simple text message in the Default Text Response.

Maximum file size allowed for all media photos videos or voice messages to be sent or forwarded through WhatsApp is 5 MB on all platforms.
Maximum file size allowed for all media photos videos or voice messages to be sent or forwarded through WhatsApp is 5 MB on all platforms. 1

Add A New Line

We separate texts for two consecutive lines using the ‘Shift + Enter’ Keys to add a new line in a text response. Text written after the ‘Shift + Enter’ Keys will be displayed in the next line of the same message in the WhatsApp Chat.

New Text Message Response

To add a new message or bubble in text responses, we separate texts for two consecutive messages using two semicolons ‘;;’. Text written after ‘;’ will be displayed as a separate message in the WhatsApp Chat.

Bold/Italic Text

To create a text message bold, we put that text inside two asterisk characters, eg. *BoldText*. Text written between two asterisk characters (do not give spaces between * and text) will be bold in the WhatsApp response.

To create a text message italic, we put that text inside two underscore characters, eg. _ItalicText_. Text written between two underscore characters (do not give spaces between _ and text) will be in Italic style in the WhatsApp response.

Use Emojis In Responses

We can use emojis and emoticons by simply adding them to our text responses. To Access Emojis:
Windows – Press ‘Windows Key’ + ‘Semicolon’
MacOS – Press ‘Command’ + ‘Control’ + ‘Spacebar’

Send A Media/Doc Response

In order to send media like images, videos, Gifs or files like .docs, or .pdf, we’ve to follow a certain format.

We use the Basic Card From Google Assistant Response to create a media/file response.

The maximum file size allowed for all media (photos, videos or voice messages) to be sent or forwarded through WhatsApp is 5 MB on all platforms.

We primarily use file URL, alt text and a file type ( IMAGE for an image, VIDEO for videos and FILE for documents).

Here's an example of a List Message👇‍

Example of a List Reply

While creating Table in Dialogflow:

In the above image:

  1. In the Title of the List Reply, we've put "Sparx Shoes".

  2. In the subtitle, we've put "Explore multiple options".

  3. In the web link title, we've added the Button Name, "Explore"

  4. In the Section title, we've added "Shoes". This section covers the name of the shoes.

  5. In the option title, we've added "Shoes Size" & in the description, we've shown the colour.

So, you can configure the table according to your use case.

After adding this, press save!

Now, let's see how this List Reply appears on WhatsApp!

"Sparx Infinity" which we added in two separate rows, club together in one. So does "Sparx Buddy".

So, if a user wants to buy a Sparx Infinity Shoe of Size 7, they will choose the option & hit send.

Points To Remember

  1. We always use Default Response to create text responses.

  2. Basic Card from Google Assistant’s Responses will be used to create media/doc responses.

  3. We can not use Custom Payloads or any other responses to create WhatsApp Messages.

  4. In order to send text responses through Webhook, we have to customise text responses as shown above.
