The Call Recording API provides read-only access to server-side call recordings associated with a conversation session. It returns recording metadata and media URLs for available audio files, supporting automated workflows such as compliance archiving, quality assurance, and analytics. A session can produce multiple recordings, such as when a call is transferred. Each recording can contain multiple files, such as separate caller and agent channels. The API does not return transcripts or other conversation text. Authenticate using a project-bound platform API key (abl_...) with the recordings.read scope. Send the key in either the x-api-key header or the Authorization: Bearer header. Studio user JWTs, JWT App assertions, and public pk_ keys are not accepted.

Retrieve session recordings

Use this endpoint to retrieve all recordings produced by a specific session. The response includes recording metadata and a list of files for each recording. Each file includes its channel, file name, size, recording timestamps, availability, and media URL details. The endpoint requires the project ID and session ID. The optional disposition query parameter controls how the media is delivered:

attachment (default): downloads the media file.
inline: allows the media to play in a browser.

Response status and availability

An HTTP 200 response can include recordings or explain why recording media is not yet available. Check data.status, data.retryable, and the availability fields on individual recordings and files.

`data.status`	Meaning
`success`	Every file has a media URL.
`partial`	At least one file has a URL and at least one does not.
`call_in_progress`	No file has a URL, and the call is still in progress.
`media_in_progress`	No file has a URL, and media is still being fetched or stored.
`media_unavailable`	No file is available, and no media is pending.

When data.recordings is empty, use data.unavailableReason and data.retryable to understand why no recordings are available. A file without a URL includes an unavailableReason and a retryable flag. Retry with backoff while the relevant retryable value is true. Stop retrying when it is false.

Media URLs

Use urlKind to determine how to retrieve each file:

signed: Send a GET request directly to the absolute URL without an authentication header.
proxied: Prefix the returned relative URL with the API host and send a GET request to it without an authentication header. Use the URL as returned; do not construct it manually.
external: Send a GET request directly to the customer-owned absolute URL.

Media URLs are short-lived where the platform controls their expiry. The default lifetime is 900 seconds, with a maximum of 3600 seconds. The expiresIn field indicates the remaining lifetime in seconds when applicable; it is null for external URLs. Treat every media URL as a bearer secret. Anyone with access to the URL may be able to retrieve the recording.

Errors and limits

400: Invalid session ID or invalid disposition.
401: Missing, invalid, expired, or revoked credentials.
403: Missing permission, unsupported credential type, or call recording not enabled for the tenant.
404: Project or session not found within the API key’s authorized scope.
413: Recording or stored-file limit exceeded.
429: Tenant request rate limit exceeded.
500: Unexpected failure.
503: Project recording settings could not be resolved; retry later.

The API allows up to 64 recordings per session and, by default, up to 32 stored files across those recordings. Tenant-level request rate limits also apply.

Audit and data handling

When at least one media URL is issued, the API records a recording:public_media_urls_issued audit event attributed to the calling API key. Responses include Cache-Control: no-store, Pragma: no-cache, and Referrer-Policy: no-referrer.
