# Changelog

> Updates to the CloudTalk API and developer documentation

<Update label="2026-08-25" description="Dialer authentication corrected" tags={["Dialer"]}>
  ## The Dialer partner API uses your standard API keys

  The Dialer endpoints (`https://api.cloudtalk.io/v1/dialer/*`) authenticate
  with the **same HTTP Basic credentials** as the rest of the API — your API
  Access Key ID as the username and API Access Key Secret as the password.

  These pages previously documented a separate per-company `x-api-key` header,
  provisioned on request. That scheme was never deployed: requests carrying an
  `x-api-key` header are rejected with `401`. If you could not authenticate
  against the Dialer endpoints before, use your standard key pair.

  Rate limiting on the Dialer surface is also **per company**, not per API
  key — a dedicated 60 requests-per-minute budget, separate from the core
  API's quota.

  Note the Dialer is a newly released product surface: depending on your
  account's rollout stage, campaigns managed through this API may not yet be
  visible in your CloudTalk Dashboard.

<Update label="2026-08-20" description="New developer documentation" tags={["Documentation"]}>
  ## A new home for the CloudTalk API docs

  These docs run on a new platform. The API reference is generated from our
  OpenAPI specification, so what you read here is what the API serves.

  What you can do now:

  * **Send requests from the page.** Every endpoint has a playground. Fill in
    your own API keys and see the real response.
  * **Point your AI tools at the docs.** There is an MCP server at
    `https://developers.cloudtalk.io/mcp` that lets an assistant search these
    pages directly. Every page also has a **Copy page** menu that hands the
    content to ChatGPT, Claude, Cursor, VS Code or Perplexity.
  * Search across every page, and a dark mode that respects your system setting.

  This changelog starts here. From now on, changes to the API land as entries on
