What Are Voice AI Public API And How To Use Them In HighLevel

You just signed a massive franchise client. They have fifty locations. They want your custom Voice AI agent deployed to every single office immediately. You do the math. Your team has to log into fifty different sub-accounts, manually build fifty identical bots, map the actions, and configure the voices one by one.

Then, the client asks for weekly call transcripts from all fifty locations. You are looking at hundreds of hours of manual data entry. You are essentially paying your team to do digital hard labor. You cannot scale an agency if your fulfillment process requires endless manual clicking.

You need to turn your Voice AI into an extensible infrastructure. HighLevel just released Voice AI Public APIs. You can now programmatically create agents, assign voices, configure actions, and extract call logs across your entire user base instantly. Let us turn your bot into a scalable enterprise solution.

Part 1: Tap Into the Developer Portal

Ready to streamline this? Here is exactly how to do it in 60 seconds:

1. Navigate to the HighLevel Developer Portal to access the Voice AI API Documentation.
2. Review the core endpoints for Call Logs, Agents, and Actions to ensure you understand the authentication requirements for your specific environment.

Part 2: Programmatically Assign Voices

Stop clicking through the voice catalog manually.

1. Call the Get Voices API to retrieve a paginated, filterable list of available voices.
2. Filter your API results by language or pass an agentId to ensure you only return compatible voices for your specific bot.
3. Use the Fetch Voice Details API to retrieve the exact metadata for a specific voice, including a preview URL for instant audio testing.

Part 3: Deploy Agents and Actions at Scale

Push updates globally without logging into a single sub-account.

1. Use the Agents APIs to programmatically manage your entire bot infrastructure. Use Create Agent to launch a new configuration or Patch Agent to push global updates to existing bots instantly.
2. If you need to clean up an account, fire the Delete Agent endpoint to permanently remove the configuration.
3. Define exactly what your agent can do using the Actions APIs. Programmatically create and update actions to trigger webhooks, retrieve CRM data, or post real-time results directly into your custom applications.

Part 4: Automate Your Call Reporting

Never export a manual call report again.

1. Connect to the Call Log APIs to extract massive amounts of call data for advanced analytics, compliance tracking, and quality reviews.
2. Use the List Call Logs endpoint to filter conversations by specific agents, contacts, call types, or exact date ranges.
3. Use the Get Call Log endpoint to pull the granular details of a specific conversation, including the full text transcript of the call.

Leveraging public APIs elevates your Voice AI from a neat dashboard feature into a highly automated, scalable revenue engine.
