Bypassing Zapier: Sync JustCall/OpenPhone Calls & Texts to GHL

Question from Reddit user:

If we use an app like JustCall or OpenPhone to communicate with customers instead of LeadConnector, do you know if we can use Zapier to bring the texts/calls into GHL?

Answer from Nabil:

The short answer is:

Can you sync JustCall & OpenPhone calls & text messages to GoHighLevel?

Yes, you absolutely can use Zapier to bring texts and call logs from services like JustCall or OpenPhone into GoHighLevel (GHL).

Both JustCall and OpenPhone have native Zapier integrations that can be set up to trigger on events like a new incoming text message or a completed call.

The core solution involves using a Zap where the phone app is the Trigger (e.g., “New Text Message” in JustCall) and GoHighLevel is the Action (e.g., “Create/Update Contact” and then “Add to Conversation” or “Create Opportunity” in GHL) to log the activity or text as a note on the corresponding contact record.

The long answer is:

Using Zapier for this integration is a common and straightforward method, but it has limitations in terms of data fidelity, speed, and cost as your volume increases.

The Zapier workflow you’ll set up should be built to trigger on a new activity in the phone app, specifically for New Inbound SMS, New Outbound SMS, New Inbound Call, and New Outbound Call.

For each trigger, you’ll need a separate Zap.

The key challenge is consistently matching the phone number from the phone app’s data to the correct contact in GHL, so your Zap’s action will first be a Search for Contact step in GHL using the phone number, followed by a Create Note or Add to Conversation step to log the activity’s details (text content, call duration, outcome, etc.) on the contact’s timeline.

An even better, more scalable, and cost-efficient solution that gives you much finer control over the data format and immediacy is to bypass Zapier and create a custom, server-side webhook integration leveraging the HighLevel API alongside the JustCall API or OpenPhone API.

These phone apps often provide webhooks that fire instantly when an event occurs, like a completed call.

You would configure the phone app’s webhook to send a payload of data to a custom endpoint you control, perhaps hosted on Google Cloud Platform or a service like Stape that can handle server-side logic.

This custom endpoint receives the webhook data, authenticates with the HighLevel API, and then programmatically searches for the contact and creates a perfectly formatted activity record or conversation entry.

Using this API-driven, server-side approach, potentially even initiating the process with an event captured via Google Tag Manager for context, ensures that call and text logs appear in GHL with no delay, in the exact format you want, and without the per-task costs or potential latency associated with a middleware service like Zapier.
