Passing Variables

Before going into each workflow component/node, it's important to understand how variables are passed between nodes.

Each node will output a JSON object. To reference specific output from a previous node, you can use dot notation.

Take the following example where we define an email subject in a code node and want to reference it in the built-in Gmail: Send Email Integration.

The code node outputs:

"email_subject": {
    "successfull": true,
    "data": {
      "results": "Email from Orchestra",
      "stdout": "",
      "stderr": "",
      "error": "",
      "sandbox_id": "sandbox-5a47"
    },
    "error": null
  }

In the Gmail integration node, we can set the Subject variable to be

{{email_subject.data.results}}

This set "Email from Orchestra" to be the Subject of the email.
