Dev Tools: External Request

External request (PRO) allows you to send an HTTP request to your server with different types of data:

  • Contact status
  • First name
  • Last name
  • Name
  • Gender
  • Language
  • Timezone
  • Live-chat URL
  • Custom fields

The external request function supports GET and POST HTTP methods. To create an external request node, go to Actions -> External request.

Once you click on Add your request button it will open the configuration window. In the configuration window, you will be able to choose the request type (GET or POST):

After you have set up your request type, you will need to set proper request URL and fill in the Headers and Body fields.
Here's the example of an External Request body from

"subscriber_id": 0,
"data": {},
"message_tag": "ISSUE_RESOLUTION"

data's {} here filled with Response Format from here:
More info about available headers could be found on the Internet. For example: 

When it is done you can test your request by going to Response tab and click on Test the request

If everything is done correctly you will get HTTP 200 Code like that:

Let’s create a default reply flow for Star Wars fans. There is a good free API test service called We want to show the film title and the opening crawls by answering any word to the bot. If the word is contained in the title, then we will show the title and the opening crawl.

Firstly, create two CUFs to save the title and the opening crawl. Then go to the Default reply section, create an Action block, and choose External Request.

We'll use an API search method and send the last user input there. Next, we need to match JSON response parameters with our CUFs.

Here is our result in the Facebook Messenger.

Hopefully this helps!
