Representative actions

  • Add community voice

    Add 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.

  • Add sources to knowledge base

    Tool 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.

  • Buy a new phone number bind agents

    This 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.

  • Create Voice AI Agent

    Create 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.

  • Create a new outbound phone call

    Initiate 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.
