Retrieve a Record by ID

To retrieve a record by the value of the entity ID from MYOB Acumatica by using the contract-based REST API, you access the needed URL with the GET HTTP method and specify the fields that should be returned in the parameters of the method. See the following sections for details on the request and the response.

Note: The entity ID is a GUID that is assigned to each entity you work with during an MYOB Acumatica session. You can obtain the value of the entity ID from the ID property of an entity returned from MYOB Acumatica.

The records of top-level entities that you retrieve through the contract-based REST API have persistent IDs, which are the values in the NoteID column of the corresponding database tables. That is, you can use the value from the ID property of a top-level entity returned from MYOB Acumatica throughout different sessions with MYOB Acumatica. However, if a record does not have a note ID (which could be the case for detail entities, entities that correspond to generic inquiries, or custom entities), this record is assigned the entity ID that is new for each new session. That is, after a new login to MYOB Acumatica, you cannot use the entity ID that you received in the previous session to work with the entity.

Any REST API response contains the _links/self field for every top-level entity it returns. The value of this field is part of the URL of a GET request to retrieve this top-level entity by its ID. The same URL can be used in a DELETE request to delete this entity.

HTTP Method and URL

If you need to obtain a particular record with the entity ID, you use the GET HTTP method and the following URL.

http://<Base endpoint URL>/<Top-level entity>/<Entity ID>

The URL has the following components:

<Base endpoint URL> is the URL of a contract-based endpoint through which you are going to work with MYOB Acumatica. This URL 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 a record.
<Entity ID> is the ID of the record to be retrieved.

For example, suppose that you want to retrieve the sales order with entity ID a6295b33-c7f6-e811-b817-00155d408001 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 should use the following URL to retrieve the sales order.

http://localhost/AcumaticaDB/entity/Default/23.200.001/SalesOrder/a6295b33-c7f6-e811-b817-00155d408001
