Strider — Configure and Use Webhooks

This series about Strider guides you through the setup process of various use cases to connect Strider and other software platforms like GitHub, GitLab, BitBucket, Slack, Heroku, HipChat, etc.

Besides the defined data flow between Strider and those apps, you can use webhooks to make a request to a specific URL once the build process finished. Additionally, you can define the data and format of your request’s payload.

Strider Series Overview

Install Strider-Webhooks Plugin

Strider provides the strider-webhooks plugin within its ecosystem index. You can install the plugin straight from the admin panel’s plugin overview.

Strider Admin Panel — Plugin Overview

Search for Web Hooks and make sure the plugin is installed. If not, click the Install button.

Configure Strider-Webhooks for Strider Project

Head over to the project’s settings page. Click the plugin link in the left sidebar. Now drag & drop the Webhooks card from Available Plugins to Active Plugins. A new link called Webhooks will appear within the left sidebar once you dropped the card into the available plugins list.

Project Settings — Plugin Overview

Click the newly created Webhooks link in the sidebar to open the detailed settings page for webhooks on this project.

You need to fill at least the value for TargetURL for HTTP Post to make the plugin work. It will send a HTTP POST request to your defined url and by default add a request body in a given format.

Strider Webhooks — Plugin Settings

Plugin Configuration options:

  • Hook Title: identifier to distinct different web hooks
  • TargetURL for HTTP Post: destination url for the POST request
  • Shared secret for HMAC-SHA1 signature: You don’t need to add the sha1= prefix. The plugin handles it for you. Just provide your shared secret.
  • Custom payload format: this doesn’t work in plugin version 0.1.2. This issue will be fixed in later version (for sure), but currently you cannot specify your preferred format for the request payload.

Once you provided your values, click Save Hooks to persist the branch specific information in the database.

Payload Data

The payload data is based on a Strider job. You can find the job format within its Mongoose model definition. Additionally, have a look at the project model, it integrates with the job model, too.

The default format looks like this:

  // job data
  project: '',
  commit_id: '',
  branch: 'job.ref.branch',
  repo_url: 'job.project.provider.config.url',
  // results
  test_exitcode: 'data.exitCode',
  finish_time: 'data.time'

While inspecting the values, you may think they look like object accessors. And you’re right. The values are parsed and used to access the provided job data. This way, you can access the provided information of any Strider job.

Additionally, a data object provides an exitCode and time property. These are the only values within the data object.

Default Request Payload

The Strider Webhooks plugins adds a request payload by default. The payload data could look like this (based on the above shown default format):

   payload: {

The absence of commit_id is because we triggered the integration run manually.

The payload data is sent as query parameters with the POST request. You may need to parse it for further operations.

Custom Payload Format

You can define a different format of your payload data and use it instead of the default one. You can use any job object property for your webhook data. Define the accessor as a value for your format property key. Have a look at the Payload Data paragraph for more information about the format configuration options.

Remember: the current version 0.1.2 doesn’t support the definition of any custom payload format. This will be fixed in future versions.

Test Webhooks Integration

That’s it. The configuration is done and we can use the webhook right away. Hit the Retest button and start the build run. Once the integration finishes, the webhook gets fired.

Strider Build Details — Webhook Fired

The webhook plugin prints a line (colored purple) at the bottom of the test phase. It uses the provided hook title as an identifier.

# Firing webhook <hook-title>

What Comes Next

We’re heading towards the finish line for this Strider series. Within this post, we show you how to configure webhooks for Strider which are executed after the integration runs finished (success or fail).

The next post illustrates how to create your own plugin for Strider.
