ZoomInfo | Phone Validation, Real Contact, and Reverse Phone Integration Guide

2 min read

Introduction #

Confidently validate and enrich phone data within your ZoomInfo GTM Studio workspace using Phone Validation API, Real Contact API, or Reverse Phone API. This step-by-step guide shows you how to activate the integration and start improving data quality.

Instructions #

To begin, you’ll need a ZoomInfo GTMStudio subscription and a Trestle API key (sign up on the Trestle Developer Portal). You will bring your own API key from Trestle and handle all billing/usage tracking from the Trestle Developer Portal.

Integration Setup #

To start, go to your ZoomInfo GTMStudio dashboard and select “Integrations” > “Connections.”

Search “Trestle” and select “Connect.”

Paste your Trestle API key and click “Connect.”

If you click “Edit Settings” and “Actions,” you can see what actions are available:

  • Phone Validation 3.0
  • Real Contact 1.1
  • Reverse Phone Lookup 3.2 

**Please note: Reverse Phone will need to be enabled via a Product Access Request in the Trestle Developer Portal. Until enabled, this API will return a 403 error.

Once the integration is installed, you will need to add the Enrichment action to your audience. Select the “Audience” button in the lefthand menu, and select the “Audience” where you would like to install the enrichment.

Select “Actions.”

Select “View All Enrichments.”

Search for and select “Trestle.”

Then, select the Trestle API endpoint you wish to query.

Phone Validation Configuration #

Real Contact Configuration #

Reverse Phone Configuration #

Please note: Reverse Phone will need to be enabled via a Product Access Request in the Trestle Developer Portal. Until enabled, this API will return a 403 error.

Once configured, an additional column will be added to your Audience sheet. Click “Results” and you can select data from the response and add it as additional column(s).

Based on this data, you can make decisions on how to handle each lead.
