Code

Learn how to run code within your Lindy workflows

Our Code action lets you run custom Python or JavaScript code directly within your flow. It's ideal for tasks like data manipulation, data analysis, API calls, complex calculations, or conditional logic.

Action Configuration

Language - The programming language you would like to write your code in. We currently support Python and JavaScript.
Variables - The variables that you will use in your code. You can set the name and value of the variable. The value of the variable can be set to an output reference from a previous step. Note, variable values will always be strings. ‍
Code - Where you will write your code. You can use the variables set in the previous steps in your code.

Reference your code output

The results or output of your code action can be used in subsequent steps. Just click on a field that you want to refer to the code action, and the code step output references should automatically appear.

Output references:

result - what your code returns
text - any text printed during code execution (i.e. the standard output of the code execution)
stderr - the standard error buffer of the code execution

Example: Calling an API

This example uses the Code Step to fetch the S&P price using the Twelve Data API and sends the price to the user.

The API key and the stock ticker are passed as variables.

And the variables are passed into a function that gets the stock price. The function is then called within the code field.

The output of the code step can be passed to the next step, which sends a message to the user. Since we are returning something in our code, we will use the result output reference.
