# Troubleshoot failed triggers

You can troubleshoot failures of your cURL or webhook initiated triggers in the Harness platform.

After a trigger runs, you can use the **Trigger Explorer** to troubleshoot cURL or webhook initiated failures. For cURL, you enter the `eventCorrelationId` from the response. For webhooks, you enter the `data` value from the webhook response payload.

### Troubleshoot webhook failures <a href="#troubleshoot-webhook-failures" id="troubleshoot-webhook-failures"></a>

To troubleshoot webhook failures, do the following:

{% tabs %}
{% tab title="cURL trigger" %}

1. Open your Harness pipeline in Pipeline Studio.
2. Select **Triggers**.
3. Select **Trigger Explorer**.
4. Select **Webhook**.
5. In **Enter Event Correlation id**, enter the `eventCorrelationId` value from the cURL response payload.

   ![](/files/GVNQVyPHYrcAU49GIDLZ)
6. Select **Search**.

   Harness returns the following information:

   * **Event Correlation Id**
   * **Trigger Name**
   * **Trigger Status**
   * **Message**
   * **Payload**

#### cURL example <a href="#curl-example" id="curl-example"></a>

**Sample cURL command**

```shell
~ % curl -X POST -H 'content-type: application/json' --url 'https://app.harness.io/gateway/pipeline/api/webhook/custom/v2?accountIdentifier=<YOUR_ACCOUNT_ID>&orgIdentifier=default&projectIdentifier=CD_Docs&pipelineIdentifier=tweety&triggerIdentifier=Custom' -d '{"sample_key": "sample_value"}'
```

**Sample response**

```json
{"status":"FAILED","data":{"eventCorrelationId":"64e3e215d2bb844cfab9e155","apiUrl":"https://app.harness.io/gateway/pipeline/api/webhook/triggerExecutionDetails/64e3e215d2bb844cfab9e155?accountIdentifier=<YOUR_ACCOUNT_ID>","uiUrl":"https://app.harness.io/ng/#/account/<YOUR_ACCOUNT_ID>/cd/orgs/default/projects/CD_Docs/deployments?pipelineIdentifier=tweety&page=0","uiSetupUrl":"https://app.harness.io/ng/#/account/<YOUR_ACCOUNT_ID>/cd/orgs/default"}}
```

In this example, you enter the `eventCorrelationId` value in the **Search** field.
{% endtab %}

{% tab title="Webhook trigger" %}

1. Open your Harness pipeline in Pipeline Studio.
2. Select **Triggers**.
3. Select **Trigger Explorer**.
4. Select **Webhook**.
5. In **Enter Event Correlation id**, enter the `data` value from the webhook response payload.

   ![](/files/GVNQVyPHYrcAU49GIDLZ)
6. Select **Search**.

   Harness returns the following information:

   * **Event Correlation Id**
   * **Trigger Name**
   * **Trigger Status**
   * **Message**
   * **Payload**

#### Webhook example <a href="#webhook-example" id="webhook-example"></a>

The pipeline below runs when a repo has a PR.

This example uses the [tweety repo](https://github.com/michaelcretzman/linux_tweet_app).

**Sample pipeline URL**

`https://app.harness.io/ng/account/\<YOUR_ACCOUNT_ID>/cd/orgs/default/projects/CD_Docs/pipelines/tweety/executions?storeType=INLINE`

**Sample response**

```json
{"status":"FAILED","data":"64e3e5b58cdd8704d75bd99d","metaData":null,"correlationId":"1a75bbef-862c-469e-b8ab-e06dd95e4999"}
```

In this example, you enter the `data` value in the **Search** field.
{% endtab %}
{% endtabs %}
