Create a webhook automation

A Registry admin can create automations in that registry. Registry automations are applied to all collections in the registry, including those added in the future.

1. Log in to W&B.

2. Click the name of a registry to view its details,

3. To create an automation that applies to the registry and all of its collections (including those created in the future), click the Automations tab, then click Create automation.

   To create an automation that applies only to a specific collection, click the collection’s action ... menu, then click Create automation. Alternatively, create an automation for a collection from the Automations section of the collection’s details page by clicking Create automation.

4. Choose the Event to watch for.

   1. Fill in any additional fields that appear, which depend upon the event. For example, if you select An artifact alias is added, you must specify the Alias regex.

   2. Click Next step.

5. Select the team that owns the webhook integration.

6. Set Action type to Webhooks. then select the webhook integration to use. Click Next step.

7. Provide a name for the automation. Optionally, provide a description.

8. Click Create automation.

• Manage the registry’s automations from the registry’s Automations tab.
• Mamage a collection’s automations from the Automations section of the collection’s details page.

From either of these pages, a Registry admin can manage existing automations:

• To view an automation’s details, click its name.
• To edit an automation, click its action ... menu, then click Edit automation.
• To delete an automation, click its action ... menu, then click Delete automation. Confiruation is required.

A team admin can test a webhook interactively with the W&B App UI.

1. Navigate to your W&B Team Settings page.
2. Scroll to the Webhooks section.
3. Click on the horizontal three docs (meatball icon) next to the name of your webhook.
4. Select Test.
5. From the UI panel that appears, paste your POST request to the field that appears.
6. Click on Test webhook. Within the W&B App UI, W&B posts the response from your endpoint.

Watch the video Testing Webhooks in Weights & Biases for a demonstration.

Send a repository dispatch from W&B to trigger a GitHub action. For example, suppose you have workflow that accepts a repository dispatch as a trigger for the on key:

on:
repository_dispatch:
  types: BUILD_AND_DEPLOY

The payload for the repository might look something like:

{
  "event_type": "BUILD_AND_DEPLOY",
  "client_payload": 
  {
    "event_author": "${event_author}",
    "artifact_version": "${artifact_version}",
    "artifact_version_string": "${artifact_version_string}",
    "artifact_collection_name": "${artifact_collection_name}",
    "project_name": "${project_name}",
    "entity_name": "${entity_name}"
    }
}

The contents and positioning of rendered template strings depends on the event or model version the automation is configured for. ${event_type} will render as either LINK_ARTIFACT or ADD_ARTIFACT_ALIAS. See below for an example mapping:

${event_type} --> "LINK_ARTIFACT" or "ADD_ARTIFACT_ALIAS"
${event_author} --> "<wandb-user>"
${artifact_version} --> "wandb-artifact://_id/QXJ0aWZhY3Q6NTE3ODg5ODg3""
${artifact_version_string} --> "<entity>/model-registry/<registered_model_name>:<alias>"
${artifact_collection_name} --> "<registered_model_name>"
${project_name} --> "model-registry"
${entity_name} --> "<entity>"

Use template strings to dynamically pass context from W&B to GitHub Actions and other tools. If those tools can call Python scripts, they can consume the registered model artifacts through the W&B API.
