Remove a credential from the vault

Retrieve a decrypted credential from the vault. For TOTP credentials, use vault.totp instead to get the code.

List all credentials in the vault (metadata only, no secrets)

Store or update an encrypted credential in the vault

Generate the current 6-digit TOTP code. Works on any credential that has a TOTP secret (standalone TOTP type or any credential with a 'totp' field). Response also includes backupCodesRemaining — call vault.get to read the actual backup codes if a fallback is needed.

Atomically consume one single-use TOTP backup code. Moves the popped code from data.backupCodes into data.usedBackupCodes (kept as an audit trail) and returns it. Use when the live TOTP code is unavailable (clock skew, device lost). Each code can only be used once.

Check a passcode a recipient submitted. Identify the verification by the same `to` recipient used to start it; no verification ID is needed. A wrong or expired code returns HTTP 200 with `success: false` and a `reason` (for example `incorrect_code` or `expired`). A verification that has already reached a final state is no longer checkable and returns 404, as does a missing verification; malformed input or rate limiting is also an error status.

Start a verification and send a one-time passcode to the email address, phone number, or both in `to`. Delivery uses one planned channel at a time and fails over when necessary. Calling again for the same recipient reuses the verification in progress and sends after the resend cooldown. The passcode is never returned; submit the recipient's code with `verify_verifications_check`. SMS, WhatsApp, and Telegram delivery draw on the workspace's balance.

Advance an in-progress verification to its next channel and send a fresh passcode. Identify it with the same `to` recipient used to create it; no verification ID is required. This bypasses the resend cooldown, and earlier passcodes remain valid. `last_channel` identifies the most recent completed send. `422 NoNextChannel` means the plan is exhausted; create the verification again to resend on the current channel.

Fetch one caller ID by ID, with its verification status. Use `voice_caller_ids_list` to find the ID.

List the workspace's caller IDs and their verification status, as a cursor page. Only a verified caller ID may be presented on an outbound call, so an unverified or missing entry here is a common reason a call is refused.

Every country the Voice service supports, each marked with whether the workspace has enabled it and whether it is currently callable. A call to a country the workspace has not enabled is refused, so check here when a specific destination fails while others succeed.

Enable or disable the countries this workspace may place voice calls to. Only the countries you list change; any country you omit keeps its current setting. Enabling one is what lets a call to it past the destination gate; disabling one refuses every call there, so confirm a disable with the user first. Read `voice_destinations_list` first for the current settings and whether Bird carries calls to the country at all.
