Log into Zapier and click "Create Zap". Choose your trigger app - this is where your data comes from (e.g., Google Forms, Typeform, HubSpot, or any of 5,000+ apps).

Popular Triggers:

  • New form submission
  • New contact added to CRM
  • New row in spreadsheet
  • New email subscriber
2

Add Webhooks by Zapier

Click the "+" button to add an action. Search for "Webhooks by Zapier" and select it. Choose "Custom Request" as the action event.

💡 Tip: You can also use POST requests in Zapier to make direct API calls to 1lookup endpoints.

3

Configure the Webhook

Set up the webhook with your 1lookup API credentials and endpoint. Here's an example for phone validation:

Method:

POST

URL:

https://app.1lookup.io/api/v1/phone

Headers:

{
  "Authorization": "Bearer YOUR_API_KEY",
  "Content-Type": "application/json"
}

Data:

{
  "phone_number": "{{1. Phone Number}}"
}

Replace the placeholder with the actual field from your trigger

Process the Response

Add another action to handle the validation results. You can use filters, paths, or direct actions based on the response.

  • → Add to mailing list
  • → Create CRM contact
  • → Send welcome email

Invalid or High Risk

Pro Tips for Zapier Integration

Use Filters Wisely

Add a Filter step after 1lookup to only continue if the risk level is "LOW" or the email is deliverable. This saves Zap tasks and ensures data quality.

Use Paths for Complex Logic

Create different paths based on validation results. For example, send valid emails to your main list and invalid ones to a cleanup queue.

Batch Processing

For large lists, consider using our batch upload feature instead of individual Zapier tasks. It's more cost-effective for high volumes.
