# updateTagAppOwnerEmail

Updates the email address of an existing application owner and reassigns every application currently owned by that owner to the new address. The request fails when another application owner already uses the requested email address. Access scopes do not follow the change. Users scoped to the previous email address are not scoped to the new address, and an administrator must grant them the new application owner scope.

### Examples

{% tabs %}
{% tab title="GraphQL" %}

```graphql
mutation UpdateTagAppOwnerEmail($input: UpdateAppOwnerTagEmailInput!) {
  updateTagAppOwnerEmail(input: $input) {
    acknowledge
  }
}
```

#### Variables

This is an example input showing all available input fields. Only fields marked as required in the schema are mandatory.

```json

  "input": {
    "tagId": "ox_tag_1",

  }
}
```

{% endtab %}

-H 'Content-Type: application/json' \
-H 'Authorization: YOUR_API_TOKEN' \
-d '{
 "query": "mutation UpdateTagAppOwnerEmail($input: UpdateAppOwnerTagEmailInput!) { updateTagAppOwnerEmail(input: $input) { acknowledge } }",
 "variables": {
    "input": {

```javascript
const query = 'mutation UpdateTagAppOwnerEmail($input: UpdateAppOwnerTagEmailInput!) { updateTagAppOwnerEmail(input: $input) { acknowledge } }';

fetch("https://api.cloud.ox.security/api/apollo-gateway", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Authorization": "YOUR_API_TOKEN"
  },
  body: JSON.stringify({
    query: query,
    // This is an example input showing all available input fields. Only fields marked as required in the schema are mandatory.
    variables: {
      input: {
        tagId: "ox_tag_1",
        email: "user@example.com"
      }
    }
  })
})
.then(response => response.json())
.then(result => console.log(JSON.stringify(result, null, 2)))
.catch(error => console.error('Error:', error));
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

query = 'mutation UpdateTagAppOwnerEmail($input: UpdateAppOwnerTagEmailInput!) { updateTagAppOwnerEmail(input: $input) { acknowledge } }'

response = requests.post(
  "https://api.cloud.ox.security/api/apollo-gateway",
  headers={
    "Content-Type": "application/json",
    "Authorization": "YOUR_API_TOKEN"
  },
  json={
    "query": query,
    # This is an example input showing all available input fields. Only fields marked as required in the schema are mandatory.
    "variables": {
      "input": {
        "tagId": "ox_tag_1",
        "email": "user@example.com"
      }
    }
  }
)

if response.status_code == 200:
    result = response.json()
    print(result)
else:
    print(f"Error: {response.status_code}")
    print(response.text)
```

{% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ox.security/api-documentation/api-reference/api--applications-owners/mutations/update-tag-app-owner-email.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
