Response

Match JSON name-value pairs of interest.

  1. Click Preview Response to see the JSON name-value pairs.

    Alternatively, to enter JSON directly, click the pencil icon. The pencil turns into a tick. Using the simple editor, ensure your code is valid. Click the tick icon to return to preview mode to continue with these steps.

  2. Select a JSON name-value pair.

    The path to the selected name-value pair is displayed in the JSON Path field.

    You may need to switch between Data and Meta to locate a specific name-value pair.

  3. To edit the JSON path, select Editable JSON.

    Following are some ways to use the editable JSON facility. For more information, see Editable JSON.

    Example

    Description
    response['0']['email'] The path refers to the first email record.
    response['*']['email'] Replace the number zero with an asterisk to refer to all the email records.
    response['{{index}}']['email'] Replace the number zero with a variable to iterate over all the email records.

  4. Give a name to the JSON name-value pair in the Assign path to variable field.

  5. In the Default Value (optional) field, assign a default value to the variable.

    The default value itself can be a variable. Type two curly brackets {{ and select from the available options.

  6. Click Assign.

    The JSON path and variable are added to the table of return values.

  7. Repeat. Select another JSON name-value pair.

You can update the table of return values at any time by assigning different variables to the JSON name-value pairs and changing the default values.
