Inquiry about REST API and Release and Hold invoice for AI Agent

Summary:

We are trying to build a AI Agent to hold and release invoice with the REST API with adding a business object.

/fscmRestApi/resources/11.13.18.05/projectCosts/{projectCostsUniqID}/action/adjustProjectCosts

It seems the POST url is not working as a ressource path. By removing {projectCostsUniqID}/action/adjustProjectCosts and only adding the transaction number works. Here is an example

/fscmRestApi/resources/11.13.18.05/projectCosts/(transaction number)

Anyone built a AI Agent similar or have documentation that could help? It is for project module and AP.

Content (please ensure you mask any confidential information):

Here is the body of the REST API :

{    "name": "adjustProjectCosts",    "parameters": [        {            "AdjustmentType": "Release invoice hold"        }  ]}
