Retrieve the Schema of Custom Fields

To retrieve the schema of custom fields of an entity—that is, the field name, view name, and type of the fields that are not defined in the contract of the endpoint for this entity—by using the contract-based REST API, you access the needed URL with the GET HTTP method. See the following sections for details on the request and the response.

Tip: Custom fields can correspond to the following elements:

The predefined elements on an MYOB Acumatica form that are not included in the entity definition
The elements that were added to the MYOB Acumatica form in a customization project
The user-defined fields

HTTP Method and URL

If you need to obtain the schema of custom fields of an entity, you use the GET HTTP method and the following URL.

http://<Base endpoint URL>/<Top-level entity>/$adHocSchema

The URL includes the following components:

<Base endpoint URL> is the URL of the contract-based endpoint through which you are going to work with MYOB Acumatica, which has the following format: http://<MYOB Acumatica instance URL>/entity/<Endpoint name>/<Endpoint version>/.
<Top-level entity> is the name of the entity for which you are going to retrieve the schema of custom fields.

For example, suppose that you want to obtain the schema of custom fields of a stock item entity from a local MYOB Acumatica instance with the name AcumaticaDB by using the system endpoint with the name Default and Version 23.200.001. You would use the following URL to retrieve the schema.

http://localhost/AcumaticaDB/entity/Default/23.200.001/StockItem/$adHocSchema

Parameters

You use no parameters when you retrieve the schema of custom fields.
