GoHighLevel phone and email validation

Check every lead in a GHL workflow before it triggers calls, texts and drips.

Why validate inside GoHighLevel

Agencies running GoHighLevel push every form fill into automated texts and calls within seconds. If the number is a landline or a fake, the automation fires anyway and the sub-account pays for the SMS. A validation step at the top of the workflow stops that and gives the agency a clean-data selling point.

GHL workflows support a Custom Webhook action that can call LookupLab directly. Store the line type in a custom field and branch the workflow on it.

Setup

Add custom fields to the contact: line_type, carrier, email_valid.
In the workflow, add a Custom Webhook action: GET https://lookuplab.io/api/v1/phone/?number={{contact.phone}} with header Authorization: Bearer YOUR_API_KEY.
Map data.line_type and data.carrier to the custom fields.
Add an If/Else on line_type: mobile goes to the SMS drip, landline goes to a call task, invalid gets tagged and skipped.

What teams build with it

Stop paying for SMS to landlines across every sub-account.
Agency-wide data quality as a billable add-on.
Reject VoIP numbers on lead-gen forms that feed a call center.

Questions

Can I use one key across sub-accounts?

Yes. One LookupLab key works in any number of workflows. Use separate keys per client if you want per-client usage.

Does it work with the Inbound Webhook trigger?

Yes, the webhook action can be placed anywhere in a workflow.
