AI-generatedSummary
Create a relation attaching a file to a specific entity by sending a POST request to the NinjaOne API's related-items endpoint for the given entity type and ID.
Inputs
- Entity Type (required) — The type of entity to which the attachment relation will be added. Options include ORGANIZATION, DOCUMENT, LOCATION, NODE, CHECKLIST, KB_DOCUMENT, END_USER, and SOFTWARE_LICENSE.
- Entity Id (required) — The numeric ID of the entity to attach the file relation to.
- Additional Fields — Optional fields to include in the request body, notably a 'File' JSON object representing the file to attach.
- Options — Optional parameters including custom JSON body to merge with request, custom HTTP headers, query filters, batching, debug flag, pagination, and timeout settings.
Output shape
a single JSON response object from the NinjaOne API representing the created attachment relation.
The output includes API response data from the POST request to the /v2/related-items/entity/{entityType}/{entityId}/attachment endpoint. If debug option is enabled, output includes request details such as URL, headers, query parameters, and body. Pagination settings do not apply for this create operation.
