### Answer I don't have visibility into the specific error you're seeing since no screenshot or error message was shared. However, based on common GHL + Retell integration issues, here are likely causes: If you're getting a 400 error: You can use the "custom webhook" function in GHL to trigger calls using the Create Call API as an alternative workaround. [(1) ]() If you're getting a "Verification Failed" error when connecting the API key: This is usually caused by either an invalid or misformatted API key, or a known GHL marketplace bug. Quick fixes: - Test the Retell API key in Postman to confirm it works - Copy it into a plain text editor to remove hidden spaces, then paste into GHL - Make sure you're using the correct key type (location vs agency) [(2) ]() If you're getting "dial_failed": Check if you're calling a US number—Retell-purchased numbers can only call US numbers currently. For international calls, you'd need SIP trunking. [(3) ]() Could you share the specific error message you're seeing? That will help narrow down the issue.

that is the error, its sending as web call and error has not joined

### Answer Based on the error you're describing ("sending as web call" and "error has not joined") , this sounds like the call is being initiated as a web call instead of a phone call, and the connection isn't being established properly. I don't have specific documentation covering this exact GHL integration error in my available sources. However, here are some things to check: Possible causes: 1. Phone number configuration issue - The

from_number

must be a phone number you've purchased and configured through Retell AI with an

outbound_agent_id

bound to it [(1) ]() 2. Missing agent binding - If your phone number doesn't have an

outbound_agent_id

configured, you need to either set one or use the

override_agent_id

parameter in your request To verify your phone number is properly configured for outbound calls:

javascript
const phoneNumberResponse = await client.phoneNumber.update('+14157774444', {
 inbound_agent_id: 'oBeDLoLOeuAbiuaMFXRtDOLriTJ5tSxD',
 nickname: 'Frontdesk Number',
 outbound_agent_id: 'oBeDLoLOeuAbiuaMFXRtDOLriTJ5tSxD',
}) ;

[(2) ]() Recommended next steps: - Verify the phone number in your GHL subaccount is properly purchased/imported in Retell - Confirm the phone number has an

outbound_agent_id

assigned - Check if the API payload is correctly structured for a phone call vs. web call Could you share a screenshot of the actual error message? That would help pinpoint the exact issue.

### Answer Currently, it's not possible to configure Retell webhooks to send only specific events like

call_completed

or

call_ended

. [(1) ]() [(2) ]() For every call, you will receive all webhook events (

call_started

,

call_ended

,

call_analyzed

) —there's no option to filter and receive only certain events at this time. A feature request has been noted for this capability. [(2) ]() Workaround suggestion: You could add logic on your receiving server/webhook handler to simply ignore the events you don't need (e.g., only process when

event === "call_ended"

or

event === "call_analyzed"

) .
