Retrieve Records by Conditions

To retrieve records that satisfy the specified conditions from MYOB Acumatica by using the contract-based REST API, you access the needed URL address with the GET HTTP method and specify filtering conditions in the parameters of the method. See the following sections for details on the request and the response.

HTTP Method and URL

If you need to retrieve the list of records that satisfies the specified conditions, you use the GET HTTP method and the following URL.

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

The URL has the following components:

<Base endpoint URL> is the URL of the 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 the list of records.

For example, suppose that you want to retrieve the list of stock item records 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 list of records.

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

Tip: In the request example below, <MYOB Acumatica instance URL> is the URL of the MYOB Acumatica instance (such as https://my.acumatica.com/MyInstance). You can omit the instance name in the URL (that is, you can use https://my.acumatica.com) if the instance is installed in the root of the website.

Usage Notes

When multiple records are retrieved from MYOB Acumatica through an endpoint with Contract Version 4, the system tries to optimize the retrieval of the records and obtain all needed records in one request to the database (instead of requesting the records one by one). If the optimization fails, the system returns an error, which specifies the entities or fields that caused the failure of the optimized request. To prevent the error from occurring, you can do any of the following:

If you do not need to retrieve the entities or fields that caused the failure, you can exclude these entities or fields from the request as follows:
- Exclude the entities from the entities specified in the $expand parameter.
- Explicitly specify the other fields to be returned (while excluding the fields that caused the failure) by using the $select parameter.
If you need to retrieve the entities or fields that caused the failure, you can retrieve the needed records one by one either by key fields, or by IDs. For more information, see Retrieve a Record by Key Fields and Retrieve a Record by ID.
