# Obtain a new Key

To obtain a new key, perform a `PUT` request with the complete key configuration. Ensure that you specify all the mandatory details. The optional fields will be automatically populated with default values or left empty if not specified.

## Request

To get a new key for a pipeline, you can use the following request. Remember to replace the `{pipelineID}` with a valid ID of a pipeline to access its `key`.

```bash
curl --location \
--request POST 'https://monitoring.de-txl.ionos.com/pipelines/{pipelineID}/key' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer $TOKEN'
```

{% tabs %}
{% tab title="Path Parameters" %}
You can update the `pipelineID` value to delete a specific pipeline:

| **Path Parameters** | **Type** | **Description**                | **Example**                            |
| ------------------- | -------- | ------------------------------ | -------------------------------------- |
| `pipelineID`        | string   | The ID (UUID) of the Pipeline. | `85c79b4b-5b40-570a-b788-58dd46ea71e2` |
| {% endtab %}        |          |                                |                                        |

{% tab title="Request Header Parameters" %}
To make authenticated requests to the API, the following fields are mandatory in the request header:

| **Header Parameters** | **Required** | **Type** | **Description**                                                                |
| --------------------- | ------------ | -------- | ------------------------------------------------------------------------------ |
| `Authorization`       | yes          | string   | The Bearer token enable requests to authenticate using a JSON Web Token (JWT). |
| {% endtab %}          |              |          |                                                                                |
| {% endtabs %}         |              |          |                                                                                |

## Response

Generates a new key for a pipeline invalidating the old one. The key is used for authentication when sending metrics.

```json
{
  "key": "momSrlgabcdef1234"
}
```

# 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.ionos.com/cloud/home/observability/monitoring-service/api-how-tos/obtain-key.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.
