API Calls

API Calls

The Chatbot can perform a webservice (API) call to an external system from within a dialogue for retrieving additional data.

If you would like to use this functionality, please contact our support ([email protected]). When the module is activated, an additional field for the URL (endpoint) of the target system appears in the detailed view of a dialogue. Furthermore there will be a field where you can choose the classical REST methods like  GET, PUT, POST, DELETE for the call.

In our example, we are performing a request to a weather service for retrieving the current weather. The variable $openweather$ holds the desired place that the user wants to get the weather info for.

This is how the API response looks like:

  "coord": {
    "lon": -0.13,
    "lat": 51.51
  "weather": [
      "id": 500,
      "main": "Rain",
      "description": "light rain",
      "icon": "10d"
  "base": "stations",
  "main": {
    "temp": 10.68,
    "pressure": 996,
    "humidity": 87,
    "temp_min": 9.44,
    "temp_max": 11.67
  "visibility": 10000,
  "wind": {
    "speed": 3.1,
    "deg": 120
  "clouds": {
    "all": 75
  "dt": 1556174048,
  "sys": {
    "type": 1,
    "id": 1414,
    "message": 0.0109,
    "country": "GB",
    "sunrise": 1556167474,
    "sunset": 1556219532
  "id": 2643743,
  "name": "London",
  "cod": 200

You can use JSON-Path for printing the API response to the bot-answer, e.g. $api.main.temp$ for the temperature. $api$ holds the JSON-Object of the response.

This is how the whole thing looks like in action:

You can also use the response in if-else conditions, for example for reacting on errors (e.g. just like in the above example, the text response will be returned only in case of success, $api.cod$ == 200).

Using special syntax you can save values from the API response to variables and make them available for further use: $temperature=($api.main.temp$)$ where $temperature$ is the variable the value should be saved to and $api.main.temp$ is the value of the response.
