By integrating Trestle’s Real Contact API into your Make.com scenario, you can automate lead grading, flag risky contacts, and seamlessly route quality leads into your workflows in real-time.
This guide will help you get started with integrating Real Contact API on Make.com.
If you are looking to integrate with our Phone Validation product, please see our Phone Validation Integration Guide.
Introduction #
To begin, you’ll need:
- An active Make.com account.
- Access to Trestle’s Real Contact API (sign up on the Trestle Developer Portal).
- A data source (form, CRM, database, or spreadsheet) capturing:
- First name
- Last name
- Phone number
- Email (optional)
Setting Up Your Scenario in Make.com #
First, log in to Make.com. Create a new scenario and add your trigger event (e.g., “Watch New Rows” on Google Sheets).

Find Trestle in the app list and select the Real Contact API action.

Enter your Trestle API Key to connect your account. You can then map out other parameters using your desired data sources.

Now, you can utilize Real Contact API in your workflow to:
- Branch or filter workflow paths based on grading or risk data.
- Update your spreadsheet, CRM, or contact record with enrichment details from Real Contact.
- Send notifications or create alerts for risky or high-value leads.
Example Scenario: Filtering leads by contact grade
- If Contact Grade = A, B, or C, continue path (e.g., auto-enroll in nurture campaign).
- If Contact Grade = D or F, divert or flag for manual review.

Optional Add-Ons #
- Litigator Checks: Flags numbers associated with known TCPA litigators.
- Email Deliverability: Checks if the email is deliverable and not a throwaway.
- Email Age Score: Estimates how long the email has been in use.
You can enable these features in your API request as needed.
