### Answer Currently, Retell AI only supports one webhook URL per agent. [(1) ]() Workarounds: 1. Create separate agents for different environments (e.g., one for dev, one for production) . This lets each agent have its own webhook URL. 2. Use dynamic variables for your webhook base URL. You can set your custom function URLs as

{{base_url}}

and then configure the "Dynamic Variables" in Global Settings → Security and Fallback Settings. This allows you to change the base URL in one place when switching environments. [(2) ]() 3. Build a proxy endpoint on your side that receives the webhook and forwards it to multiple destinations—this would be custom logic outside of Retell. For registering webhooks, you have two options: [(3) ]() - **Account-level webhook**: Set up through system settings → webhooks tab (applies to all agents) - **Agent-level webhook**: Set up through the agent detail page (overrides account-level for that agent)

### Answer ## Status The Retell AI HubSpot integration is currently in Beta. [(1) ]() ## Features Included The integration enables the Make a Phone Call action in HubSpot workflows. This action: - Creates an outbound call using your AI agents - Pauses the workflow until the call is finished Once a call is completed, HubSpot is automatically updated with: - **Activity Timeline**: Post-call analysis and call summary - **Call Log**: Recording and detailed call transcript - **Company Record**: Call logs also appear on the associated company timeline Common workflow use cases include: - New lead qualification - New contact created triggers - Deal stage change follow-ups - Re-engagement campaigns - Appointment reminders - Post-purchase follow-up ## Community Issues There have been reports of errors with the HubSpot integration. One user reported receiving this error consistently: "There was a problem completing this action. We didn't get a response from the connected app." [(2) ]() Troubleshooting suggestions from the community include: - Verify your Retell connection with HubSpot - Check if your API key is valid - Try disconnecting and reconnecting the integration ## Release Date I don't have specific information about when the HubSpot integration was released in the available sources. ## Stability Given the Beta status and the community reports of timeout/connection issues, the integration may still have some stability concerns. [(1) ]() [(2) ]() The documentation notes you must have a Retell AI account and an agent with a connected phone number for it to work properly. [(1) ](

### Answer Based on the available documentation, the Retell AI HubSpot integration does not appear to fetch or sync historical/old call data. [(1) ]() The integration works by triggering outbound calls through HubSpot workflows and then updating HubSpot with call data after each new call completes. Specifically: - Call outcomes, post-call analysis, and summaries are logged to the Activity Timeline - Recordings and transcripts appear in the Calls tab - These updates happen in real-time as new calls are made through the workflow action The documentation describes a forward-looking workflow trigger model (e.g., "new lead qualification," "record created," "deal stage changes") rather than a historical data import feature. If you need to sync older call data from Retell into HubSpot, you would likely need to use the Retell API to retrieve historical call records and then push them to HubSpot via HubSpot's API or a custom integration—this would be custom logic outside the native integration.

### Answer If calls aren't logging to HubSpot after following the setup instructions, here are key things to verify: ## Configuration Checklist 1. **Webhook URL**: Confirm you copied the Webhook URL from the integration form and pasted it into the Webhooks section of your Retell Dashboard (Settings → Webhooks) . [(1) ]() 2. **API Key**: Verify you copied the *Secret Key (Webhook) * from Settings → API Keys in the Retell Dashboard and entered it in the Retell API Key field on the installation form. 3. **Activity Filters**: When viewing call results in HubSpot, ensure your activity filters include "Retell AI" — otherwise the call analysis won't appear in the Activity tab. 4. **Phone Number Requirement**: You must have an agent with a connected phone number for calls to work properly. 5. **Workflow Enrollment**: Calls only log when contacts are enrolled in the HubSpot workflow and the call completes. Check that your workflow is published and contacts are actually being enrolled. ## Known Issues Other users have reported similar issues with the HubSpot integration showing errors like "There was a problem completing this action. We didn't get a response from the connected app." [(2) ]() Suggested troubleshooting steps from the community: - Verify your Retell connection with HubSpot is still showing as connected - Check if your API key is still valid - Try disconnecting and reconnecting the integration Since the integration is currently in Beta, there may be stability issues.
