Webhook developer metrics

Updated on December 24, 2025
URL copied to clipboard!

The Webhook developer metrics module provides a dashboard to view and analyze an organization’s usage of webhooks. This feature provides data visualization of integration insights.

NOTE:

The Datahub subscriptions module uses webhooks as a push mechanism for data transmission.

The dashboard provides valuable insights into the performance, reliability, usage, and impact of webhooks within a system or application. These metrics enable developers and stakeholders to monitor, troubleshoot, and optimize the webhook integration experience.

The dashboard provides details in the following tabs:

  • Overview: Displays legends and graphs based on various metrics, such as Webhook request, Webhook response time, and Top 3 event groups
  • Webhook calls: Lists all the webhook transactions
  • Events: Lists the event details or payloads for webhook calls

Overview #

The Overview tab includes the following sections:

  • Legends that contain data aggregation and summarization based on webhook metrics, such as total webhook request, webhook response time, and number of subscriptions.
  • Graphical representation of various metrics, such as webhook request, webhook response time, and message size.

In the Datahub Portal module > click Webhook. The Webhook developer metrics page is displayed.



Duration

You can view the webhook details for the selected period. The following options are available: day, week, month, quarter, and year.



NOTE:
  • By default, webhook details are displayed for the current week.
  • When you select the duration, the date range is displayed on the left.

Legends #

The webhook metrics are displayed as legends.

Available legends

NOTE:

Values for each metric are displayed for the selected duration.

Legend name

Description

Total webhook request

The total number of webhook requests sent for data transmission

Webhook success

The total number of webhook requests successfully executed while transmitting data

The percentage of successfully delivered webhook requests is displayed.

Webhook success percentage = (Total number of successfully delivered webhook requests / Total number of webhook requests sent) * 100

Webhook failed

The total number of undelivered webhook requests while transmitting data

The percentage is displayed of the webhook requests that were not delivered.

Webhook failure percentage = (Total number of unsuccessful webhook requests / Total number of sent webhook requests) * 100

This metric visualizes how many webhooks have failed, so that appropriate action can be initiated if too many webhooks are failing.

Webhook response time

Average response time a receivers application’s endpoint has taken to acknowledge and respond to an incoming webhook request

Message sent

Total number of sent webhook messages while transmitting data

Message size

Total size of all sent webhook messages while transmitting data

Number of subscriptions

Total number of subscriptions in the Datahub subscription module

Active subscriptions

Total number of subscriptions that are actively storing and transmitting the data to subscriber organizations

Inactive subscriptions

Total number of subscriptions that are inactive (not storing and transmitting data to subscriber organizations)

This section describes the various graphical representations based on certain webhook metrics for the selected duration.

TIP:

Hover over each graph to view the data points and other details for that particular duration.

Webhook request #

The Webhook request graph charts the number of webhook requests that were successful versus those that failed.


Webhook response time #

The Webhook response time graph provides data on the average webhook response time.

NOTE:

Message sent #

Message size #

Top 3 event groups #

The Top 3 event groups clustered column chart provides data on the three most used event groups.

NOTE:
  • The bars represent different event groups used in thousands. The top 3 events may vary for different durations, hence, the colors representing these events may change.

NOTE:
  • If webhook data is unavailable, the following message is displayed on the Webhook developer metrics page: “No records to show”.
  • If webhook data cannot be retrieved due to background processes, the following message is displayed on the Webhook developer metrics page: click Reload to refresh the page.
