# Update a glossary entry

> Replace an existing glossary entry by ID, including changing its source term. Only the glossary owner can modify entries.

Replace an existing glossary entry by ID, including changing its source term. Only the glossary owner can modify entries.

```http theme={null}
POST https://api.voicecheap.ai/v1/actions/glossary_entry_update
```

## Authentication and permissions

<ParamField header="x-api-key" type="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.
</ParamField>

Required permissions: `glossary:write`.

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

## Parameters

<ParamField body="requestId" type="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}$`.
</ParamField>

<ParamField body="glossaryId" type="string" required>
  Text value.

  Minimum length: 1. Maximum length: 200. Pattern: `^[^/]+$`.
</ParamField>

<ParamField body="entryId" type="string" required>
  Text value.

  Minimum length: 1. Maximum length: 200. Pattern: `^[^/]+$`.
</ParamField>

<ParamField body="sourceText" type="string" required>
  Text value.

  Minimum length: 1. Maximum length: 500.
</ParamField>

<ParamField body="targets" type="object" required>
  JSON object. See the complete input schema for its nested fields.
</ParamField>

## 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.

<RequestExample>
  ```bash cURL theme={null}
  curl --request POST 'https://api.voicecheap.ai/v1/actions/glossary_entry_update' \
    --header "x-api-key: $VOICECHEAP_API_KEY" \

  ```

  ```javascript JavaScript theme={null}
  const input = {
    requestId: '58d5bb53-00d0-4692-bdaf-c6650ee87e30',
    glossaryId: 'user_123__english',

    method: 'POST',
    headers: {
      'x-api-key': process.env.VOICECHEAP_API_KEY,

    body: JSON.stringify(input),
  });
  const body = await response.json();
  if (!response.ok) throw new Error(body.code + ': ' + body.message);
  console.log(body);
  ```

  ```python Python theme={null}

  response = requests.post(
      "https://api.voicecheap.ai/v1/actions/glossary_entry_update",
      headers={"x-api-key": os.environ["VOICECHEAP_API_KEY"]},

  body = response.json()
  if not response.ok:
      raise RuntimeError(f"{body.get('code')}: {body.get('message')}")
  print(body)
  ```
</RequestExample>

## 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 the entry saved for the supplied glossary and normalized source term.

## Result fields

| Field | Description |
| - | - |
| `data.glossaryId` | Glossary identifier for the workspace owner and normalized source language. |
| `data.sourceLanguage` | Normalized source language name. |
| `data.entry.entryId` | Identifier of the saved entry. It can change when the source term changes. |
| `data.entry.sourceText` | Trimmed, lowercased source term returned by the glossary. |
| `data.entry.targets` | Map from normalized target language names to translation rules. |
| `data.entry.targets.<language>.text` | Text to use for that target language. |
| `data.entry.targets.<language>.mode` | translate or keep. |
| `data.entry.targets.<language>.applicationMode` | smart or strict when stored on the target rule. |
| `data.entry.createdAt` | Entry creation timestamp in milliseconds as returned by the save operation. |
| `data.entry.updatedAt` | Entry save timestamp in milliseconds. |

## 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.

```bash theme={null}
curl --request POST 'https://api.voicecheap.ai/v1/actions/action_request_get' \
  --header "x-api-key: $VOICECHEAP_API_KEY" \
  --header 'Content-Type: application/json' \
  --data '{"requestId":"58d5bb53-00d0-4692-bdaf-c6650ee87e30","operation":"glossary_entry_update"}'
```

```json HTTP 200 theme={null}

  "data": {
    "requestId": "58d5bb53-00d0-4692-bdaf-c6650ee87e30",
    "operation": "glossary_entry_update",
    "status": "completed",
    "createdAt": 1792144800000,
    "updatedAt": 1792144820000,
    "resultStored": true,
    "result": {
      "glossaryId": "user_123__english",
      "sourceLanguage": "english",
      "entry": {
        "entryId": "a8792157cb4f27fb949c035f45518c61e884bb86",
        "sourceText": "product",
        "targets": {
          "french": {
            "text": "Produit",
            "mode": "translate",
            "applicationMode": "smart"
          }
        },
        "createdAt": 1792152000000,
        "updatedAt": 1792152000000
      }
    }
  }
}
```

## Operation notes

* Changing sourceText can change entryId. Use the returned entryId for subsequent calls.
* A changed source term removes the previous entry ID before saving the new normalized term.
* Language and target rules are the same as glossary\_entry\_upsert. Only the owner may modify this glossary.

## Usage

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