Manufacturing REST API Endpoint Documentation?

You're right in noting that Acumatica's REST API documentation, particularly for specialized endpoints like MANUFACTURING, can be sparse or hard to find. However, there are several strategies and resources that can help you navigate the Acumatica API and get the documentation or reference material you need:

1. Acumatica Open University
   Training Resources: Acumatica Open University offers various courses and resources that include API development, which sometimes covers specialized endpoints. While it might not be as detailed as you’re used to with platforms like HubSpot, it’s still a valuable resource.

  Web Services & Integration Training: Look for courses related to web services and integration. These can sometimes include details on less commonly documented endpoints.

 2. Custom Endpoint Documentation
   Web Services Endpoints Screen: As you mentioned, the `Web Services Endpoints` screen in Acumatica is your primary resource for discovering the available fields, actions, and configurations within an endpoint. For the MANUFACTURING endpoint:
     1. Go to `System Management > Integration > Configure > Web Service Endpoints`.
     2. Select the MANUFACTURING endpoint and review the available entities, actions, and fields.

3. Swagger and OData Metadata
   Swagger: Some Acumatica instances expose a Swagger UI for their REST API, which might include endpoints like MANUFACTURING. Accessing the Swagger interface usually provides a more interactive way to explore available endpoints and their methods.

   OData Metadata: You can access OData metadata to see the structure of the endpoints. By navigating to:
     
     {{url}}/OData/{{endpointName}}/$metadata

     Replace `{{url}}` with your Acumatica instance URL and `{{endpointName}}` with the MANUFACTURING endpoint. This can give you an XML document that describes the entity types and sets available.

4.Trial and Error Method
   Using F12 Developer Tools: As a last resort, use the browser’s Developer Tools (F12) while interacting with the Acumatica interface. By capturing the network traffic, you can observe the exact API calls being made by the Acumatica UI when interacting with the Manufacturing module. This can give you clues about the correct usage of the API.
