What is Retell AI?

Retell AI is a voice AI platform for building and operating AI-powered voice agents that can handle real phone calls and web calls. It combines telephony, LLM-driven dialog, and operational tooling (agents, voices, call recordings, and knowledge bases) to run automated conversations at scale.

With Konnectify, you can automate how calls and chats are initiated, tracked, and updated—while keeping your agent configuration, knowledge base sources, and call outcomes in sync with the rest of your business stack.

What you can automate

• Purchase, look up, or delete Retell phone numbers

• Initiate phone calls, web calls, and batch call campaigns

• Register pre-existing calls and update call states/metadata

• Create, update, and end chat sessions for agents

• Create and maintain knowledge bases and their sources

• Retrieve voice agents, LLMs, conversation flows, and available voices

API & Authentication

Authentication type: API Key (credentials)

Konnectify connects to Retell AI using an API Key. You’ll paste your Retell API key into the Retell AI connection in Konnectify. Keep this key secure—anyone with access can make API requests on your behalf.

Where to find it: In your Retell AI dashboard (API / developer settings).
How it’s used: Sent with each request to authenticate and authorize operations like calls, chats, knowledge bases, and voices.

What the Retell AI connection can do

Based on available triggers and actions in this connector, Konnectify can access these functional areas:

Calls: create calls/web calls/batch calls, update calls, retrieve call details and recordings, register external calls.
Chats: create, retrieve, update, and end chat sessions.
Agents & flows: retrieve voice agents, chat agents, Retell LLMs, and conversation flows.
Phone numbers: create (purchase/setup), find, and delete phone numbers.
Knowledge bases: create, add sources, retrieve, and delete knowledge bases.
Voices: add/clone voices, get voice details, and search voices.

Important: plan restrictions & rate limits Retell AI features (e.g., phone number purchasing, call concurrency, recordings, knowledge base limits) can vary by plan and region. Additionally, API rate limits may apply. If a workflow runs at high volume (batch calls, frequent polling), add retries/backoff and avoid unnecessary calls.

How to connect Retell AI to Konnectify

Prerequisites

A Retell AI account with API access enabled
Your Retell AI API Key
In Retell AI: at least one agent/voice configured (required for initiating calls/chats)
A Konnectify account and permission to create/edit workflows

Add Retell AI to a Workflow

Create a new Workflow in Konnectify (or open an existing one).
Click Add step and search for Retell AI.
Select a Trigger (to start the workflow) or an Action (to perform an operation).

Authorize via API Key authentication

When prompted, create/select a Retell AI connection.
Paste your API Key into the connection field.
Save. Konnectify will validate the key when making requests.

Configure the Trigger or Action

Choose the Retell AI event (Trigger) or operation (Action) you need.
Map required fields using outputs from previous steps (e.g., phone number, agent ID, dynamic variables).
Use test data to validate configuration before moving on.

Warning For call-initiating actions (Create Call / Create Web Call / Create Batch Call), ensure the agent/voice configuration exists in Retell AI and that the destination number and region/permissions are allowed by your Retell plan.

Test the Workflow

Run a test to confirm Retell AI returns the expected objects (call/chat/agent details).
Check mapped fields carefully (IDs, phone numbers, dynamic variables).
Review step logs for errors and retry behavior.

Activate the Workflow

Turn on the workflow.
Monitor early runs to confirm call/chat creation and updates behave as expected.
Iterate: add filters, retries, and notifications for production reliability.

Triggers 1

This connector includes 1 trigger. The available trigger is polling-based, meaning Konnectify checks Retell AI at intervals to detect new or updated records.

FAQ

How does Konnectify authenticate with Retell AI?

Konnectify uses API Key authentication. You provide your Retell AI API key when creating the connection, and Konnectify sends it with each request to authorize actions like creating calls and managing chats/knowledge bases.

Which Retell AI plans are supported?

Any Retell AI plan that provides API access should work. Features like phone number provisioning, concurrent calling, recordings, and knowledge base limits may vary by plan and region—confirm capabilities in your Retell AI account.

Are Retell AI triggers webhook-based or polling-based?

The New Call trigger is polling-based. Konnectify checks Retell AI periodically to detect new/updated calls. If you need near real-time behavior, consider shorter polling intervals (within rate limits) or combine with external events that start a workflow.

How do I prevent duplicate processing of the same call?

This connector does not include an “upsert” action, so deduplication should be handled in your workflow. Use a unique identifier (e.g., call ID) and store it in your datastore/CRM, or add a Konnectify filter step to skip if the ID was already processed.

What happens if Retell AI rate limits my workflow?

If Retell AI returns rate-limit responses, reduce polling frequency, avoid unnecessary “Get” calls, and add retry/backoff in your workflow design. Batch operations (like Create Batch Call) can also concentrate traffic—plan concurrency accordingly.

Can I connect multiple Retell AI accounts to Konnectify?

Yes. Create separate Retell AI connections in Konnectify—each with its own API key—and choose the desired connection per workflow step (useful for managing multiple workspaces/environments).

How should I handle call recordings and sensitive data?

Use Get call to retrieve recording metadata/details, then store only what you need. Follow your organization’s privacy and consent requirements for call recording, apply least-privilege access to API keys, and avoid logging sensitive fields in workflow logs where possible.
