How to fetch updated inventory from contract based rest api?

Hi ​@Namrata13 ,

• Use the Inventory Summary screen (IN401000) via the REST API.
• Create a custom endpoint or extend an existing one.
• Add the InventorySummary entity to the endpoint and include the required grid fields (like InventoryID, Warehouse, QtyOnHand, Available Qty, etc.) under the Details section.
• Use the PUT method with appropriate filters (like InventoryID) in the request body to get real-time changes.
   

  

   

  

   

Hello ​@jinin ,

Thank you for your reply. I already checked and tried inventory summary entity. But the problem is that here it is asking for InventoryID. But I need the entity where only I can pass LastModifiedDate filter I don’t want to pass InventoryID. And without InventoryID it is not giving me the result. 

Hope you get my point. 

Help me on this.

Thank you

Hi ​@Namrata13 ,

Since the information can't be retrieved directly, you'll need to create a custom Generic Inquiry (GI) using the INSiteStatusByCostCenter table. Apply a filter on the Last Modified DateTime field, and then create an endpoint entity based on that GI. Please give this approach a try.

​@Namrata13 you can get ‘storage details’ inquiry via OData to get this data.

E.g.

{{sitename}}/t/Company/api/odata/gi/DB-StorageDetails?$filter= LastModifiedDateofWarehouseQty ge 2024-01-01

 (example for 2025r1 Acumatica version)

Hello,

Thank you for both response ​@jinin and ​@Dmitrii Naumov .

​@jinin regarding creating Generic inquiry, I never created before. So, I need to do some RNDs on that. If you can suggest any tutorial regrding this..

​@Dmitrii Naumov, Will try your approach and let you know whether its working or not. 

​@Dmitrii Naumov I tried with odata concept but it is giving me unauthorized error. I want to ask I am using oauth in rest api but same token not working for odata.

Can you please guide me on that?

Thank you

​@Namrata13 the same token should be good for OData too. 

What version of Acumatica do you have?

Hello ​@Dmitrii Naumov ,

This is staging acumatica in which I am testing. and also shared postman where I am getting unauth error

Hi @Namrata13,

As suggested by @jinin, we can retrieve a list of items using a date filter.

Please find below the steps to achieve this using a Generic Inquiry:

you can access GI using Endpoint as below,

http://localhost/ACV24R1241120026/entity/EndpointName/20.200.001/InventoryLastModified?$expand=InventoryLastModifiedDetails

Request:

{  

    "Date": {

        "value": "2024-02-15T18:25:43.511Z"

    }

}

Steps:

1. Import the Generic Inquiry.

2. Create an Endpoint for it.

3. Pass the date parameter in the request.

Hope above helps!!

Hello ​@Rakshanda ,

Thank you for your response. Will try that Generic Endpoint and let you know if it is working or not

​@Namrata13 You are on 24r1 version. 

In this version you can use the following URL instead

​@Dmitrii Naumov Thank you. 

The URL you shared is working perfectly—thank you for that! I do have a few questions for clarification:

1. Will the same URL structure work for other Acumatica customers, or can it vary based on their environment or configuration or version?

2. If any inventory-related transaction occurs—such as sales order creation, purchase receipt, item receipt, item issue, etc.—will the /DB-StorageDetails OData endpoint reflect the updated inventory accordingly?

3. How can I retrieve the company name using the API?

I hope my questions are clear.
Thank you again for your support!

​@Namrata13 

1. It should work for all currently supported Acumatica versions and configurations. For 2026 version it’ll probably need to be changed to the one I’ve provided first here

   ​@Namrata13 you can get ‘storage details’ inquiry via OData to get this data.

   E.g.

   {{sitename}}/t/Company/api/odata/gi/DB-StorageDetails?$filter= LastModifiedDateofWarehouseQty ge 2024-01-01

    

    (example for 2025r1 Acumatica version)

    

2. Yes, correct.
3. I don’t think there is a good way to do it. You should consider the company name a part of credentials and have a setting for that along with site URL

​@Dmitrii Naumov 
like in acumatica we are able to view tenant list. Can’t we get this via api? Beacuse we are looking for the automation and actually our all api call created by contract based rest api and only to fetch updated inventory I have to use odata version. That’s why I am looking for the way where I want least involvement from client.

Hope you understand.

 

​@Namrata13 when you log in in the REST API  or get a token, you should already have a specific tenant name (because tokens cannot be shared between tenants).

As for the branches, yes, the branches can be retrieved using Default endpoint CompaniesStructure entity.

Dear Support Team,

Hello,

The endpoint which you have suggested is working for one acumatica account but not working for another acumatica account. Url is-

What changes I have to done to this account?

​@Namrata13 I can see two possible reasons for that:

1. They’ve disabled that GI for OData or deleted it. You can check if the GI has ‘Expose via OData’ checkbox checked
2. The user you are accessing it with does not have the access rights
