Install ClawLink
Add the ClawLink plugin to OpenClaw once. Takes under a minute.
ClawLink connects OpenClaw to Retell AI in one click with managed credential setup, no manual app setup, and 12 tools your agent can call from chat.
ClawLink gives OpenClaw a more practical Retell AI setup than rolling your own integration. Instead of building auth, token refresh, and tool wiring yourself, you connect once and start using real Retell AI actions from chat.

Three steps. No developer needed.
Add the ClawLink plugin to OpenClaw once. Takes under a minute.
Click Connect next to Retell AI in the ClawLink dashboard. Authenticate in a single click.
Ask OpenClaw to use Retell AI in plain English. ClawLink routes the call.
These use cases change by integration category, available tools, and setup model. This page is not just a cloned template with the logo swapped.
Use Retell AI inside OpenClaw when you want model output and operational actions to happen in one flow.
ClawLink makes Retell AI accessible from chat so teams can test useful workflows before writing custom automation around them.
OpenClaw can call Retell AI, inspect the results, and help iterate without a separate integration project first.
12 Retell AI tools available the moment you connect. Every action is one chat message away.
retellai_add_community_voiceAdd a community voice from ElevenLabs to your Retell voice library. Use when you need to import a shared community voice for use in your agents.
retellai_add_knowledge_base_sourcesTool to add sources (documents, URLs, text) to an existing knowledge base in Retell AI. Use when you need to add additional content to a knowledge base. At least one of knowledge_base_texts, knowledge_base_files, or knowledge_base_urls should be provided.
retellai_buy_a_new_phone_number_bind_agentsThis endpoint allows purchasing a new phone number with a specified area code and binding it to designated agents for inbound and outbound calls. It requires JSON with agent IDs and area code. Responses indicate the creation status or errors. A purchased phone number is a prerequisite for initiating outbound calls; an empty phone number inventory will prevent outbound calls from being made.
retellai_create_a_new_outbound_phone_callInitiate an outbound call by POST to '/v2/create-phone-call'. Requires 'from_number' and 'to_number' in E.164 format. Optional overrides and metadata supported. On success, returns call details including type, status, and IDs.
retellai_create_a_new_web_callThe /v2/create-web-call endpoint creates a web call with a unique agent ID, returning call details like type, token, call ID, and status in JSON format, with a 201 response. Optional metadata and variables can be included.
retellai_create_agentCreate a new voice AI agent with specified configuration. Use when you need to set up a voice-based AI agent with custom response engine, voice settings, and behavior configuration.
+ 6 more Retell AI tools available after you connect.

That is fine if you want to build and maintain the integration yourself. Most teams just want Retell AI working from chat.
Credential handling
Manual setup
Collect, validate, store, and rotate the Retell AI API key yourself, then make sure every tool call uses the right account.
With ClawLink
Users complete the hosted ClawLink setup once and the connected Retell AI account becomes available to the agent without you building credential management.
Ongoing maintenance
Manual setup
You own refresh logic, permission debugging, environment config, and every provider-specific edge case for Retell AI.
With ClawLink
ClawLink handles the repetitive integration plumbing so your team can focus on the workflow instead of the infrastructure.
Agent usability
Manual setup
You still need to expose the right Retell AI actions to the runtime in a format your agent can reliably use.
With ClawLink
12 tools for Retell AI are already exposed through ClawLink, so the agent can read and act from chat immediately.

Connect retellai through ClawLink's hosted Composio setup.
Retell AI relies on an API key connection, but ClawLink still keeps the setup in one place and exposes the tools to the agent after the account is linked.
OpenClaw works best when the request is concrete. Ask for a specific outcome in Retell AI instead of a vague "check this" instruction.
Reconnect Retell AI from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.
Check whether the connected account has access to the workspace, inbox, store, or project you are trying to use. Most failures at this stage are permission mismatches, not ClawLink bugs.
Double-check that the API key for Retell AI has the right scopes or account access. A valid key can still be too limited for some reads or writes.
