Webhook event notifications
Webhooks are typically used to connect two different applications. When an event happens on the trigger application, it serializes data about that event and sends it to a webhook URL from the action application—the one you want to do something based on the data from the first application.
You can listen to events on your Chord OMS so your integration can automatically trigger the desired actions.
Chord OMS uses webhook to notify your application when an event happens in your account. Webhooks are useful for asynchronous events like when an order is completed, canceled, or when a shipment changes status.
Begin using webhook with your Chord OMS integration in just two steps:
- Create a webhook endpoint on your server.
- Register the endpoint on the Chord OMS Dashboard to go live
Metaphorically, webhooks are like a phone number that Chord OMS calls to notify you of activity in your Chord OMS. The webhook endpoint is the person answering that call who takes actions based on the specific information it receives.
Non-metaphorically, the webhook endpoint is just more code on your server. The webhook endpoint has an associated URL (e.g. ). The Chord OMS notifications are Webhook Event objects. This Webhook Event object contains all the relevant information about what just happened, including the type of event and the data associated with that event.
Webhook combines elements that create a notification and reaction system within a larger integration.
The first step to adding a webhook to your Chord OMS integration is to build your own custom endpoint. Creating a webhook endpoint on your server is no different from creating any page on your website.
The Chord OMS POSTs the webhook data to your endpoint in JSON format for each event occurrence. The full event details are included and can be used directly after parsing the JSON into an Event object. The webhook endpoint needs to expect data through a POST request and confirm the successful receipt of that data.
To acknowledge receipt of an event, your endpoint must return an allowed HTTP status code to the Chord OMS. All response codes outside these, including 3xx, indicate to the Chord OMS that you did not receive the event.
If the Chord OMS does not receive a valid HTTP status code, the notification attempt is repeated up to 5 times.
Because properly acknowledging receipt of the webhook notification is so important, your endpoint should return an allowed HTTP status code prior to any complex logic that could cause a timeout.

Your webhook endpoints should be configured to receive only the types of events required by your integration. Listening for extra events (or all events) will put undue strain on your server and is not recommended.
This is a list of all the types of events we currently send.
Event Name | Payload Object | Description |
order_completed | Order | Occurs whenever an order is completed |
order_cancelled | Order | Occurs when an order is cancelled |
shipment_shipped | Shipment | Occurs whenever a shipment is shipped |
shipment_updated | Shipment | Occurs whenever a shipment receives an update (like a status change different from shipped or a tracking details update) |
shipment_delivery_status_updated | Shipment | Occurs whenever the tracking code related to the shipment receives a delivery status update |
stock_item_back_in_stock | Stock Item | Occurs whenever a product variant is back in stock |
stock_item_out_of_stock | Stock Item | Occurs whenever a product variant goes out of stock |
Shipments
Stock Items
After building, and deploying your webhook, set up the endpoint so the Chord OMS knows where to send the events.
Add endpoints from the Dashboard:
Add endpoints with the API
Existing webhook endpoints can be updated or deleted in the Dashboard’s Webhooks settings section. View events When viewing information about a specific endpoint through the Dashboard, you can check all the attempts related to an endpoint by clicking on that endpoint edit icon in the Webhooks section:
Click on the Attempts tab and on Details for all attempts made
Q: What is the Webhook Attempts Search Tool and why is it important? The Webhook Attempts Search Tool is a feature that allows you to search and audit webhook attempts made by the system. This tool is essential as it aids in monitoring and validating webhook attempts, particularly in scenarios where a system claimed it did not receive a webhook from another system. Q: Can we search through the request body of webhook attempts? Yes, you can search through the request body of webhook attempts. However, we limited the request body search to a maximum of 30 days - any longer and the response time becomes rather long. Q: How can we access the Webhook Attempts Search Tool? You can access the Webhook Attempts Search Tool via the attempts page, which includes simple search filters using ransack. Additionally, links with pre-filled ransack parameters have been added on the orders, subscriptions, and endpoints pages, allowing you to navigate directly to the attempts page for easier access and auditing of webhook attempts.
You can also find webhooks for a specific order or shipment through the Order page. On the right-hand Order Information menu should be two links that will display the webhooks related to an order or its shipments.
