Field Info → Post Undefined

AI-generated

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 "Field Info" resource and the "Post Undefined" operation, it sends a POST request with a complex JSON body to the Halo PSA API endpoint related to field information.

Typical use cases include automating the creation or update of custom fields, validation rules, access controls, and other metadata configurations in Halo PSA. For example, a user might use this node to programmatically define or modify custom fields and their associated properties in bulk, which is useful for large-scale configuration management or integration workflows.

Properties

Name Meaning
Body A JSON object representing detailed field information including default values, custom fields, validation data, access control settings, lookup requests, visibility conditions, and restrictions. This property accepts a complex nested JSON structure that defines multiple aspects of field metadata in Halo PSA.

The "Body" property expects a JSON input structured as shown in the provided default value, which includes arrays and objects for:

  • defaultvalue_table
  • values
  • table_values
  • table_info (with nested fields like customfields, add_customfields, edit_customfields, etc.)
  • client_restrictions
  • org_restrictions
  • database_lookup_triggers
  • validation_data
  • visibility_conditions
  • access_control
  • sqlcfvariables
  • lookup_request

This allows comprehensive specification of field-related data in one request.

Output

The node outputs the JSON response received from the Halo PSA API after making the POST request. The output JSON reflects the result of the operation performed on the "Field Info" resource, such as confirmation of created or updated fields, error messages, or other relevant data returned by the API.

If the API returns binary data (not indicated here), it would be handled accordingly, but based on the code and operation, the output is purely JSON.

Dependencies

  • Requires an active connection to the Halo PSA API.
  • Needs credentials containing:
    • Base URL of the Halo PSA instance
    • Tenant identifier
    • Client ID
    • Client Secret
  • These credentials must be configured in n8n prior to using the node.
  • The node uses HTTP requests with appropriate headers for authentication and content type.

Troubleshooting

  • No credentials returned!
    This error occurs if the node cannot retrieve the required API credentials. Ensure that the API key credential is properly set up and assigned to the node.

  • Resource or Operation not found
    If the specified resource or operation does not exist, verify that the correct resource ("Field Info") and operation ("Post Undefined") are selected.

  • Invalid JSON in Body
    Since the "Body" property requires valid JSON, malformed JSON will cause errors. Use proper JSON formatting and validate the structure before running the node.

  • API Request Failures
    Network issues, incorrect credentials, or invalid request payloads can cause the API call to fail. Check the error message returned in the output JSON for details.

  • Continue On Fail Behavior
    If enabled, the node will continue processing subsequent items even if some fail, returning error details in the output JSON.
