How Webhooks function?

Webhooks are HTTP callbacks that users set up, which kicks into action when certain things happen (trigger event). When one of these trigger events takes place on your website, the website sends an HTTP request to the web address linked to the webhook. 

This allows apps to share data in real time without someone having to start the process by hand. Every time a user create, modify, or remove orders, products, or customers in WooCommerce, you may use Webhooks to set off events. 

Webhooks are similar to APIs but are simpler than API to use. With an API, you need to manually request data from another app. Webhooks, on the other hand, are automated and run automatically between two applications. They have a message or payload and are sent to a unique URL, which is nothing but essentially the user’s end address. 

Benefits of setting up Webhooks in WooCommerce

Listed below are some of the benefits of Webhooks that will encourage you to use them for your WooCommerce store:

1. Real-time notifications – Webhooks helps in providing real-time notifications for various events allowing you to respond immediately to important events on your webstore. It also allows customers to get immediate updates on their purchase progress, shipping details, or account changes etc.
2. Third-party service integrations – Webhooks allows you to easily connect your WooCommerce store with CRM systems, marketing platforms and various inventory management tools.
3. Customizable and flexible – Webhooks will allow you as a user to define the exact events and actions that trigger them. Due to their versatility, Webhooks may be tailored to your business’s specific needs.
4. Economical integration and automation – As they allow you to integrate and automate various parts of your WooCommerce store without paying an extra fee, webhooks could be a relatively cost-effective way for your business. 
   

Setting Up Webhooks in WooCommerce

Follow the below steps and install and set-up the Webhooks in your WooCommerce store:

A. Access Webhooks settings: Go to WooCommerce. Click on ‘Settings’, go to ‘Advanced’ and select ‘Webhooks’.

Source – WooCommerce.com

B. Create a New Webhook: Click on ‘Create a New Webhook’ or alternatively you can also click on ‘Add Webhook’.

Source – WooCommerce.com

C. Configure Webhook Details:

• Name: Give your webhook a descriptive name.

• Status: Set the status to Active (delivered), Paused (not delivered), or Disabled (delivery failure).

• Topic: Choose the event that will trigger the webhook (e.g., Order Created, User Updated or Product Updated etc).  This also has Action and Custom options.

• Delivery URL: Enter the URL where the webhook payload will be sent. Example: https://example.com/webhook-endpoint

• Secret: Add a secret key for security purposes. The secret field generates a hash using which receiving end authorizes the webhook. 

• API version: There are 3 API versions available for your selection. 

• Delivery method: Select “POST” to send the data as an HTTP POST request.

• Event data: Select the data you want to be sent with the webhook payload such order details or customer data etc.

• Headers: Add here any custom headers that your receiving endpoint is expecting.

Example: 

{

  “Content-Type”: “application/json”,

  “Authorization”: “Bearer YOUR_TOKEN”

}

• Retry delivery: Choose whether to retry webhook deliveries automatically upon failure.

• Timeout: Webhook timeout settings control how long a webhook can take to respond before it times out. Assign a maximum time for the webhook to complete processing.

Timeout settings prevent unnecessary occupation of server space and helps avoid instability that may be cause by hung processes. 

Some examples of Webhook timeout settings are – 

1. Dialogflow: The default timeout is 5 seconds, but you can increase it.
2. Chargebee: You can set connection, read, and execution timeouts for test and live sites.
3. Kubernetes: The default timeout is 10 seconds, but you can set it to a shorter value.
4. Webhook.site: The default timeout is 5 seconds, but you can set it to a value between 1 and 30 seconds.

• Limit delivery attempts: Choose the maximum number of delivery attempts. 

D. Save Webhook: Click “Save Webhook” to activate it.

Testing Webhooks in WooCommerce

A. Create a RequestBin URL:

• Go to RequestBin.
• Click on the “Create a RequestBin” button.
• Copy the generated URL. This URL will be used as the delivery URL for your webhook.

B. Trigger the Webhook Event: Perform the action that will trigger the webhook you have created. For instance, if the triggering event for your webhook is “Order Updated”, try to update an order on your WooCommerce store.

C. Check the RequestBin:

• Go back to RequestBin and refresh the page.
• You should see the webhook request listed. 
• Click on it to view the details, including the payload and headers.

Edit or Delete the Webhooks

Editing or deleting a Webhook is relatively simple. If you want to edit the previously created Webhook or delete one, follow the below steps:

A. Find the Webhook you want to edit or delete.

B. Hover the pointed over the name. The Webhook ID, Edit and Delete permanently options will appear.

C. Click Delete permanently option or click Edit to make and Save changes. 

D. You can even do bulk deletion of Webhooks with the help of dropdown.

How information is transferred through Webhooks

Webhooks transfer information between applications using HTTP requests: 

A. Event triggers: When a specific event occurs in the source application, it triggers a webhook. 

B. Data serialization: The source application serializes the data about the event. 

C. HTTP request: The source application sends an HTTP request to the target application’s webhook URL. The request consists of the following:

• URL – This is the address where you would like to send the request.

• Body or Payload – The body contains the information you want to send to another app.

• Header – This instructs the application on how to decode information in the header (XML, JSON, etc.).

• Request method – This could be a GET, POST, PUT, or DELETE request.

D. Data delivery: The target application receives and processes the data. 

E. Callback message: The target application sends a callback message to the source application to confirm if the data was received. 

Best practices for using Webhooks

• Security: Use secret keys to ensure that the webhook payload is secure.

• Error handling: Implement retry mechanisms to handle failed webhook deliveries.

• Conditional asset loading: To minimize needless load, make sure that styles and scripts are only loaded on pages that require them.

• Logging: Record all webhook events for troubleshooting and auditing purposes. WooCommerce maintains a log of all triggering events for Webhooks. 

You can view these logs by navigating to WooCommerce > Status > Logs.

Scaling guidelines for Webhooks

• Message queues: To effectively manage large numbers of Webhooks, use message queues. This aids with load management and guarantees prompt processing of webhooks.

• Retry mechanisms: To deal with brief failures, increase the amount of retries for Webhook delivery. This can be changed with the woocommerce_max_webhook_delivery_failures filter function.

• Monitoring and logging: To facilitate debugging and performance tracking, monitor the performance of your Webhook and record significant occurrences.

Best tools to test WooCommerce Webhooks.

Testing WooCommerce webhooks is very important because they need to provide the right output for your business and make the consumer experience even better. There are many ways for you to test the working of webhooks that are integrated with your ecommerce store. 

We have prepared a handy list of some of the best tools available in the market for testing:

A. Webhook.site

Webhook.site provides unique, custom URLs for testing webhooks and callbacks. It allows you to monitor incoming HTTP requests in real-time, view headers, and inspect the payload in detail. 

B. RequestBin

RequestBin is a popular tool that will allow you to create temporary URLs to capture and inspect the HTTP requests. It provides important data such as headers and payloads, To ensure the effective functioning of the webhooks you have created for your webstore.

The RequestBin tool will allow you generate up to 20 requests, which you are allowed to keep for maximum time period of 48 hours.

C. Beeceptor

Beeceptor allows you to create mock endpoints that behave like real APIs. You can handle incoming requests and simulate different response scenarios, which is helpful for testing various webhook events and responses.

D.  Mocky

Mocky lets you create custom URLs with predefined responses. This is useful for testing webhook mechanisms where you need a known response structure. It helps in simulating different scenarios and validating the webhook’s behavior.

E.  Pipedream

Pipedream is a powerful integration platform that allows you to build and test workflows involving webhooks. It provides detailed logs and debugging tools to help you understand how your webhooks are functioning.

F.  Postman Mock Server

Postman Mock Server allows you to create mock servers to test your webhooks. You can define the expected responses and validate the webhook requests against these responses. It’s a very useful tool for testing webhooks and debugging any issues therein.

Common issues and their solutions

Whenever you create a Webhook for your WooCommerce store, it is first tested by WooCommerce before activation. To test the Webhook, WooCommerce will send a sample data to the delivery URL. 

Listed below are some of the common issues faced by users when using Webhooks for their website:

• Webhook not functioning: Ensure the webhook is set to active and the delivery URL is correct. The endpoint should be able to receive the Webhook.

• Failed deliveries or retry mechanisms: Check the response status codes and increase the retry limit if necessary. The successful responses usually bounce back with the results 2xx, 301, or 302. 

If you see the response as 404 or 5xx errors, this can be due to the issues with the delivery URL. The Webhooks are disabled automatically in case of 5 continuous unsuccessful status. 

• Payload format issues: Validate the payload structure and ensure it matches the expected format of the recipient application. These issues arise due to error in JSON structure or XML data format. 

You can make use of tools to test and debug the payload before deploying it. If you want to use or are using third party API’s, ensure they are up to date with changes.

• Rate limiting: It is the maximum number of requests that a user can make on your store within a defined time period in order to prevent application overload. Exceeding these maximum limits can lead to the total rejection of all incoming webhook transactions. 

To optimize and reduce the number calls made by a webhook within a specified time frame, batch processing could be a useful solution. 

• Invalid URLs: Always double-check the endpoint URLs in your webhook configurations. Ensure the URLs do not have spelling errors, adhere to the required format and are not outdated. 

Further, the URLs should point to an active endpoint capable of processing the requests. You can check the URL independently for its functioning before using it in a Webhook.

• SSL certificate issues: Using unverified or outdated SSL certificates can cause connections getting turned down, resulting in trust problems when webhooks are exchanged. This can put consumer data privacy at risk. 

Check that your SSL certificates are bought from trusted vendor, duly updated from time to time, are set up right and the server getting them trusts the certificate.
