# Pipeline trigger tokens API **(FREE)**

You can read more about [triggering pipelines through the API](../ci/triggers/index.md).

## List project trigger tokens

Get a list of a project's pipeline trigger tokens.

```plaintext
GET /projects/:id/triggers
```

| Attribute | Type    | required | Description         |
|-----------|---------|----------|---------------------|
| `id`      | integer/string | yes      | The ID or [URL-encoded path of the project](index.md#namespaced-path-encoding) owned by the authenticated user |

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/1/triggers"
```

```json
[
    {
        "id": 10,
        "description": "my trigger",
        "created_at": "2016-01-07T09:53:58.235Z",
        "last_used": null,
        "token": "6d056f63e50fe6f8c5f8f4aa10edb7",
        "updated_at": "2016-01-07T09:53:58.235Z",
        "owner": null
    }
]
```

The trigger token is displayed in full if the trigger token was created by the authenticated
user. Trigger tokens created by other users are shortened to four characters.

## Get trigger token details

| `trigger_id` | integer | yes      | The trigger ID           |

```shell
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/1/triggers/5"
```

```json
{
    "id": 10,
    "description": "my trigger",
    "created_at": "2016-01-07T09:53:58.235Z",

    "owner": null
}
```

DELETE /projects/:id/triggers/:trigger_id

|----------------|---------|----------|--------------------------|
| `id`           | integer/string | yes      | The ID or [URL-encoded path of the project](index.md#namespaced-path-encoding) owned by the authenticated user      |

## Trigger a pipeline with a token

Trigger a pipeline by using a pipeline [trigger token](../ci/triggers/index.md#create-a-trigger-token)
or a [CI/CD job token](../ci/jobs/ci_job_token.md) for authentication.

With a CI/CD job token, the [triggered pipeline is a multi-project pipeline](../ci/jobs/ci_job_token.md#trigger-a-multi-project-pipeline-by-using-a-cicd-job-token).
The job that authenticates the request becomes associated with the upstream pipeline,
which is visible on the [pipeline graph](../ci/pipelines/downstream_pipelines.md#view-multi-project-pipelines-in-pipeline-graphs).

If you use a trigger token in a job, the job is not associated with the upstream pipeline.

```plaintext
POST /projects/:id/trigger/pipeline
```

Supported attributes:

| Attribute   | Type           | Required               | Description |
|:------------|:---------------|:-----------------------|:---------------------|
| `id`        | integer/string | **{check-circle}** Yes | The ID or [URL-encoded path of the project](index.md#namespaced-path-encoding) owned by the authenticated user. |
| `ref`       | string         | **{check-circle}** Yes | The branch or tag to run the pipeline on. |
| `token`     | string         | **{check-circle}** Yes | The trigger token or CI/CD job token. |
| `variables` | array          | **{dotted-circle}** No | An [array of hashes](index.md#array-of-hashes) containing the variables available in the pipeline, matching the structure `[{ 'key': 'UPLOAD_TO_S3', 'variable_type': 'file', 'value': 'true' }, {'key': 'TEST', 'value': 'test variable'}]`. If `variable_type` is excluded, it defaults to `env_var`. |
