Extracting respondent emails in Zapier

MetaSurvey sends response data (like question types and answers) as arrays. To use a respondent’s email in later steps like “Create Contact” or “Send Email,” you need to extract it using a small script in Zapier.

Step-by-Step Setup

1. Set up your Webhook Trigger

Select Webhooks by Zapier as your trigger and choose Catch Hook. Copy your unique Webhook URL and paste it into your MetaSurvey settings. Send a test response to ensure Zapier receives your data.

1. Add the ‘Code by Zapier’ Action

Add a new step and select Code by Zapier. Set the Action Event to Run JavaScript.

1. Map your Input Data

In the Input Data section, you must create two specific keys and map them to your webhook data:

• questionTypes: Map to 1. Responses Question Type

• values: Map to 1. Responses Value

1. Insert the Extraction Code

Copy and paste the following code into the Code box:

// Split the input data into arrays for question types and values
const questionTypes = (inputData.questionTypes || '').split(',');
const values = (inputData.values || '').split(',');

// Initialize an object to hold the extracted email
let emailOutput = { email: null };

// Loop through the question types to find the email value
for (let i = 0; i < questionTypes.length; i++) {
  if (questionTypes[i].trim() === 'email') {
    emailOutput.email = values[i] || null; // Assign value or null
    break; // Exit loop once found
  }
}

// Return the output object
return emailOutput;

1. Test and Use

Click Test Action. Zapier will return a single email field. You can now map this field in your next steps, such as adding a lead to HubSpot, Brevo, or sending a personal “Thank You” email.
