Webhook → Post Undefined

Overview

This node integrates with the Halo PSA API, allowing users to perform various operations on different resources within the Halo PSA system. Specifically, for the Webhook resource and the Post Undefined operation, it accepts a JSON body payload that can represent complex nested data structures related to events, mappings, steps, and other configurations.

Typical use cases include:

  • Sending detailed webhook event data to Halo PSA.
  • Automating the creation or update of complex configurations in Halo PSA via webhook POST requests.
  • Integrating external systems by pushing structured event and configuration data into Halo PSA workflows.

For example, a user might configure this node to send a webhook POST request containing event triggers and step actions to automate ticket routing or notification rules in Halo PSA.

Properties

Name Meaning
Body A JSON object representing the webhook payload. It includes nested arrays and objects such as events, mappings, steps, input_variables, standalone_methods, and integrations. This structure allows defining agents, conditions, roles, user roles, chat teams, rules, output variables, and many other detailed configurations relevant to the webhook's purpose in Halo PSA.

The "Body" property expects a JSON input, which can be dynamically set using an expression (e.g., ={{ JSON.parse($value) }}), allowing flexible and complex data to be sent.

Output

The node outputs an array of JSON objects corresponding to the response from the Halo PSA API for each input item processed. Each output item contains:

  • json: The parsed JSON response returned by the Halo PSA API after sending the webhook POST request.
  • pairedItem: Metadata linking the output to the original input item index.

If an error occurs during the request and the node is configured to continue on failure, the output will contain an error message in the json.error field instead of the expected response.

The node does not output binary data.

Dependencies

  • Requires an API key credential for authenticating with the Halo PSA API. This credential must provide:

    • Base URL of the Halo PSA instance.
    • Tenant identifier.
    • Client ID.
    • Client Secret.

  • The node uses these credentials to set HTTP headers for authentication when making requests.

  • No additional external dependencies are required beyond the Halo PSA API access.

Troubleshooting

  • No credentials returned!
    This error indicates missing or misconfigured API credentials. Ensure that the required API key credential is properly set up in n8n with all necessary fields filled.

  • Resource or Operation not found
    If the specified resource or operation is invalid or not supported, the node will throw an error. Verify that the resource is "Webhook" and the operation is "Post Undefined" as expected.

  • Invalid JSON in Body
    Since the Body property expects valid JSON, malformed JSON input will cause parsing errors. Use the built-in JSON editor or validate your JSON before running the workflow.

  • API Request Failures
    Network issues, incorrect base URL, tenant, client ID, or secret can cause request failures. Check connectivity and credential correctness.

  • Continue On Fail Behavior
    If enabled, the node will output error messages in the JSON output instead of stopping execution. This helps in debugging but may require handling error outputs downstream.

Links and References

Note: The provided Body JSON schema is highly complex and deeply nested, reflecting the rich data model of Halo PSA webhooks. Users should tailor the JSON payload according to their specific integration needs and refer to Halo PSA API documentation for exact field definitions.
