# Add Contacts Using Our REST API

If you want to import contacts from third-party websites and apps or through automation tools like Zapier or Pabbly, you can use our REST API.

All you have to do is send a **POST request** (from your website, app, or automation tool) with your contact data in the required JSON format to your unique webhook URL, and that’ll add/update the contact for you.

For detailed setup instructions and example webhook request format, [__check out this guide__](https://help.wanotifier.com/en/article/manage-your-contacts-using-rest-api-1xp06ly/).
