​

Before you start

Make sure you have:

• Sympana Connector installed in GoHighLevel
• a Retell account

• a calendar created in GoHighLevel

​

Step 1. Open the Retell app

After installing Sympana Connector in your GoHighLevel account, click on the Retell app.

​

Step 2. Open the API key prompt

A pop-up appears asking you to get your API key from Retell.

​

Step 3. Go to the Retell dashboard

Click the quick link labeled Retell AI Dashboard + API Keys. If you still need to create a Retell account first, use the RetellAI.com signup link at the top of this page, then return here for your API key.

​

Step 4. Copy your Retell API key

Once you click the link, you will land on the API key section in Retell.

​

Step 5. Paste the API key into Sympana Connector

Create a new API key or copy an existing one. Then return to GoHighLevel, open the Sympana Connector app, and paste the key into the API key field.

​

Step 6. Add your first connection

Once the account is connected, click Add Your First Connection. Before you do, make sure:

• you have a phone number connected to Retell
• you have a calendar created in GoHighLevel
• your calendar does not require a form before booking

​

Step 7. Name the connection

Create your connection name. Most users use the name of the AI agent they are connecting.

​

Step 8. Select the Retell agent

Choose which Retell agent you want to connect.

​

Step 9. Select the phone number

Choose the phone number you want to use for the connection.

​

Step 10. Select the calendar

Choose the GoHighLevel calendar you want to connect.

​

Step 11. Select functions and variables

Choose the functions and global variables you want to use. Some global variables, such as phone number and contact ID, are required. Then click Create Connection.

​

Step 12. Verify the connection

Your first Retell connection should now be active. If something does not work during setup, join the Sympana Discord server to get the fastest support from someone on the Sympana team.
