Acumatica REST API – Issue with Wildcard (*) in Bill of Material Revision URL

Hi Acumatica Support Team,

We are facing an issue while uploading attachments to a Bill of Material (BOM) using the Acumatica REST API.

Scenario:

We need to upload a file to the following BOM record:

• BOM ID: BOM000023

• Revision: *

• File Name: AACOMPUT01.jpg

We are using the following API URL for uploading the attachment:

http://localhost/AcumaticaQMS26R1/entity/ABPManufacturing/25.100.001/BillOfMaterial/BOM000023/*/files/AACOMPUT01.jpg

When we execute the API request, we receive the following error:

A potentially dangerous Request.Path value was detected from the client (*)

Questions:

1. What is the correct REST API URL and HTTP method (PUT) for uploading an attachment when the BOM Revision value is *?

2. Does Acumatica support * as a valid Revision key in the attachment upload URL?

3. Can we use %2A instead of * to avoid the ASP.NET request-path validation error?

4. Is there any alternative supported approach for uploading attachments to a BOM with Revision *?

Expected Result:

We want to successfully upload AACOMPUT01.jpg as an attachment to BOM BOM000023 with Revision * using the Acumatica REST API.

Please provide the recommended API URL and a working example for this upload scenario.

Thank you for your assistance.
