Examples of Using Set Focus

Example

In this example, the robot will access the API of coindesk.com and retrieve the price of bitcoin in EUR.

Steps:

  1. Create a new project

  2. Create a new Sequence and rename it.

  3. Add a new activity HTTP Rest Request in the newly created Sequence and edit the following parameters:

  • URL: "https://api.coindesk.com/v1/bpi/currentprice.json"

  • Method: GET

Watch the robot in action:

  • Output: a string variable (e.g. outputREST)

  • Response Code: an int32 variable (e.g. responseCode)

  • Add a new activity JSON Deserialization in the same Sequence and edit the following parameters:

  • Content: the same string variable (e.g. outputREST)

  • Output: a JObject variable (e.g. rate)

"Today, "+DateTime.Now + ", 1 bitcoin = " + rate["bpi"]["EUR"]["rate"] + " EUR"

, where rate["bpi"]["EUR"]["rate"] is the JSON hierarchy.
