Supplier Order Header → Post Undefined

AI-generated

Overview

This node integrates with the Halo PSA API to perform operations on various resources, specifically here focusing on the "Supplier Order Header" resource with a "Post Undefined" operation. The node sends HTTP requests to the Halo PSA backend, allowing users to create or update supplier order headers by posting complex JSON data structures representing orders, lines, invoices, assets, schedules, and related metadata.

Typical use cases include automating procurement workflows, syncing supplier order data from external systems into Halo PSA, or programmatically managing supplier orders in bulk. For example, a company could use this node to automatically post new supplier orders generated from an ERP system into Halo PSA for further processing and tracking.

Properties

Name Meaning
Body A JSON object representing the full supplier order header data to be posted. This includes nested arrays and objects such as custom fields, lines, invoices, assets, schedules, addresses, approval processes, external links, and more. The structure is highly detailed and customizable to match the Halo PSA API's expected payload for supplier order headers.

The "Body" property expects a JSON string that will be parsed and sent as the request body. It supports deeply nested structures to fully describe the supplier order header and its related entities.

Output

  • The node outputs an array of JSON objects corresponding to each input item processed.
  • Each output item contains a json field with the response data returned from the Halo PSA API after posting the supplier order header.
  • If the API call fails and "Continue On Fail" is enabled, the output will contain an error message inside the json.error field.
  • No binary data output is produced by this node.

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 appropriate HTTP headers for authentication.
  • No other external dependencies are required beyond the n8n environment and the configured Halo PSA API credentials.

Troubleshooting

  • Common issues:

    • Missing or invalid credentials will cause the node to throw an error "No credentials returned!".
    • Incorrect resource or operation names will result in errors like "Resource Supplier Order Header not found" or "Operation Post Undefined not found for resource Supplier Order Header".
    • Malformed JSON in the "Body" property will cause JSON parsing errors before the request is sent.
    • Network or API errors will be surfaced in the node output; enabling "Continue On Fail" allows workflow continuation despite errors.

  • Error messages and resolutions:

    • "No credentials returned!": Ensure the API key credential is properly configured and selected in the node.
    • "Resource ... not found" or "Operation ... not found": Verify the resource and operation names are correct and supported by the node.
    • JSON parse errors on the "Body" input: Validate the JSON syntax before running the node.
    • API errors (e.g., 4xx or 5xx responses): Check the API endpoint, request body content, and credentials for correctness.
