Permanently delete an accessible project and its translations.

POST https://api.voicecheap.ai/v1/actions/projects_delete

Authentication and permissions

string

required

Send a VoiceCheap API key in this header. Authorization: Bearer with the same API key is also supported. OAuth access tokens are accepted only by MCP, not by this REST endpoint.

Required permissions: projects:delete. An active paid subscription is required. Permissions do not change team roles, resource ownership, media credits, or plan limits.

Parameters

string

required

Text value.Minimum length: 1. Maximum length: 200. Pattern: ^[^/\\]+$.

string

Optional at the transport boundary: the server injects an identifier before validation when omitted. Supply your own stable UUID v4 to recover safely from a lost response.Format: “uuid”. Pattern: ^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-4[0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$.

Complete input schema

The JSON Schema below preserves the exact field names, nested types, defaults, bounds, and accepted values exposed by discovery. Additional cross-field rules are listed in the operation notes.

{
  "type": "object",
  "properties": {
    "projectId": {
      "type": "string",
      "minLength": 1,
      "maxLength": 200,
      "pattern": "^[^/\\\\]+$"
    },
    "requestId": {
      "type": "string",
      "format": "uuid",
      "pattern": "^[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-4[0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}$",
      "description": "UUID v4 for this action. Reuse the same ID with identical arguments on retries."
    }
  },
  "required": ["projectId"],
  "additionalProperties": false
}

Idempotency

Use a UUID v4 in requestId or the Idempotency-Key HTTP header for each mutation. Reuse the same identifier and identical arguments after a network failure. If both are supplied, they must match. Replaying a saved request does not repeat the operation or charge another monthly call. Failed or interrupted requests are not restarted automatically. Every mutation can return HTTP 202 when a retry finds the same request still running, even when its first execution is normally synchronous. If execution completed but resultStored is false, a retry returns HTTP 200 with saved request state instead of the original result. Retrieve the output through its domain history, result, or download action.

Request examples

Replace example resource identifiers and media keys with values returned for your account. Keep the request identifier stable when retrying the same mutation.

Response

A successful first execution returns HTTP 200 with the operation result under data. A replay may return saved request state instead. The example shows one supported response, not every optional field. Returns an acknowledgement after permanently deleting the accessible project and its translations.

Result fields

Field	Description
`data.success`	True after the deletion completes.
`data.message`	Project deletion acknowledgement.
`data.projectId`	Deleted project identifier.

Recover and poll this request

Use the same identifier even after a lost connection. If resultStored is false, retrieve the output through the corresponding history, result, or download action. Never start a second generation merely to check progress.

  }
}

Operation notes

This is a destructive action. It does not return the deleted project document.
The handler result contains success, message and projectId; the action is invoked through the same POST action transport as other operations.

Usage

Each successful invocation consumes one monthly API/MCP call. Media credits and the operation’s own generation allowances also apply.
