Webhooks

About Webhooks

Webhooks allow you to build or set up integrations, which subscribe to certain events in the Etlworks Integrator. When one of those events is triggered, we'll send an HTTP POST or GET request to the Webhook's configured URL. Webhooks can be used to update your external system about events happening in the Etlworks Integrator.

Create a Webhook

Only users with the Administrator role can create Webhooks. To set up a Webhook, go to the Webhooks page of your account. From there, click Add webhook.

Alternatively, you can choose to build and manage a Webhook through the Webhooks API.

Webhooks require a few configuration options before you can make use of them. We'll go through each of these settings below.

URL

The payload URL is the URL of the server that will receive the webhook POST or GET requests.

The URL can be empty if the webhook triggered by the event is meant to send the email notification only.

Method

The Webhook can make either POST or GET requests to your server. Regardless of your choice, you will receive several headers in the Webhook request:

• X-Etl-Webhook-Event-Id: unique ID of a Webhook request.
• X-Etl-Webhook-Event: the name of the event that triggered a Webhook request.
• X-Etl-Webhook-Id: the ID of the Webhook.
• X-Etl-Webhook-Entity-Id: the ID of the object that was affected during an event. For example, if the event is Flow.Created then it will be the ID of the newly created Flow.
• X-Etl-Webhook-Entity-URL: the API URL that can be used to retrieve the entity.

If you select POST method for your Webhook, then you will also receive a payload as the body of the request which contains all the information related to the event that happened in the system.

Email

The comma-separated list of email addresses to send the nofification to when the webhook is triggred by the event.

Content type

Webhooks can be delivered using different content types:

• The application/json content type will deliver the JSON payload directly as the body of the Post request. Here's a payload example:

• {
    "eventId": "7027e72b-9005-4fcc-8385-8da47249136a",
    "eventType": "Flow.Executed",
    "webhookId": 1,
    "entityId": 11225,
    "entity": {
      ...
    },
    "entityUrl": "https://app.etlworks.com/rest/v1/flows/1?auditId=11225",
    "timestamp": 1588429200207
  }

• The application/x-www-form-urlencoded content type will send the payload as URL encoded form parameters. Here's a payload example:

• eventId=32f54fa6-41ae-432e-a720-4373bdf72e6d&eventType=Flow.Executed&webhookId=1&entityId=11157&timestamp=1588165500224

Include Entity

If Include Entity is selected, then all entity data will be included in the payload. Note that an entity ID will be specified in the payload regardless of this option.

Enabled

By default, Webhooks are enabled. You can choose to temporarily disable the delivery of Webhook payloads by deselecting Enabled.

Events

Events are at the core of Webhooks. These Webhooks fire whenever a certain action is taken in the system. You can choose to receive Webhooks on All events, or click on Select individual events and then select only those events that you are interested in.

Secret

Setting a Webhook secret allows you to ensure that POST requests sent to the payload URL are from the Etlworks Integrator and weren't tempered with. When you set a secret, you'll receive the X-Etl-Webhook-Signature header in the Webhook POST request.

The value of that header is equal to the HMAC SHA-1 hash signature of the payload (request body). To verify the request, you can calculate the signature of the payload on your side using the same secret and compare it to the one you received in the X-Etl-Webhook-Signature header.

Basic Authentication

If your endpoint is protected by Basic Authentication, you can provide a username and password. Webhook will make sure to set the proper authentication header on the request.

Custom Headers

Custom headers allows you to specify any number of additional headers you would like to be set on the Webhook request

Debug a Webhook

 After you created your Webhook(s), you can inspect recent deliveries by clicking on View events.

View events lets you see the last 100 events of each Webhook. By expanding an individual delivery, you'll be able to witness precisely what information the Etlworks Integrator is attempting to send to your server. This includes both the HTTP Request and Response headers and payload.
