Phone number: Linqblue

Last updated: February 19, 2026

Recognizing the diverse requirements of our clients, we have integrated a new, cutting-edge phone line provider. Through streamlined integration, Linqblue allows you to send messages from GHL while all conversations are automatically delivered and mirrored in your Charlie dashboard, creating seamless bidirectional communication.

This guide covers configuration steps, technical specifications, and key insights to ensure smooth integration and optimal performance.

Linqblue integration is currently only supported for GoHighLevel (GHL)

Prerequisites:

  • Active Linqblue account with administrative access.

If You Don't Have Admin Access: Contact your Linqblue account administrator to request appropriate permissions or have them complete the integration on your behalf.

Configurations

All conversations, whether initiated from GHL or managed by Charlie, will appear in both platforms simultaneously, ensuring complete visibility and seamless handoff between systems. For that we need to do the following configurations:

In Linqblue

  1. Login with your credentials, make sure you are viewing as Organization Admin not as Team Admin/Member Mode

  2. Look for the integrations sections in the left side menu, and click on it

  3. Select the CRM option, and click on the top right button "Create new"

  4. Select GHL option and sync it with your account's credentials

    1. Successful integration will display a new "Linq" section within your GHL dashboard that will show general settings and overall information.

Webhook implementation

We have a seamless and fast integration through webhooks that ensures transparency between systems, no need of maintenance, and real time synchronization.

  1. First you'll need to login to: zero.linqapp.com with the same credentials you have for your Linqblue account

  2. Look for the "API" section at the bottom of your left side menu

  3. Click in the "Webhook" option

  4. In here you'll see a URL that you need to copy to generate the new webhook that will connect your Linqblue account with Charlie

    If you don't see the URL: Contact Charlie support or your AM before proceeding

  5. Hit the "Create webhook" button

  6. In the pop-up, paste the URL, and select the "Message received" option

  7. Click in the "Create webhook" button. Immediately After Webhook Creation, a security pop-up appears displaying a Secret Key

    1. COPY & SAVE somewhere safe the Secret key that will appear

    2. Do NOT close the pop-up until you've confirmed the key is saved

Paste the URL you copied and hit save

A Security pop-up containing a SECRET KEY will appear next. Important: This key is displayed only once. You must copy and save it, as it is required for all subsequent configurations.

With Charlie team

The final step requires coordination with Charlie's technical team to complete backend configuration.

  1. Forward the Secret Key to your CX/AM

  2. The Charlie team will include that information in the back-end

  3. Your CX/AM will notify you when the integration is completed

  4. Test that the inbound messages are showing up in GHL and in Charlie. Ensuring that Charlie is able to generate replies to the conversation
