Hello Team, My company integrates with Acumatica, and I have a few questions:1. Could you provide a link to API on how we can send a request to Acumatica so that to update data in Acumatica.For example, we want send a request to Acumatica to update the Credit Limit.2. Can we update the Credit Limit if the Credit hold is On.Thank you,Andrew

Hello Team,Could you please provide a list of errors that the Acumatica back-end can return during the record updating request?We are going to use the API to update the Customer's Credit Limit in Acumatica.And It would be perfect if you could provide the list of back-end errors that Acumatica can return during the request.Thank you!

Hi, I followed this example https://help-2018r1.acumatica.com/(W(2))/Wiki/ShowWiki.aspx?pageid=d806636f-3cb8-4fd6-bc1e-fef9cdf9683dto delete an item. It works on Stock and Non-StockItem but it does not work on a Ledger. Instead of passing the line below to delete a StockItem    string stockItem = rs.Delete("StockItem", inventoryID);     I tried     string msg = rs.Delete("Ledger", "0915ACT");but it does not work.I have tried endpoints 6.00.001, 17.200.001, 18.200.001 and 20.200.001 and all of them failed.Using EndPoint 20.200.001 fails to login using the same code.The ledger screen is  localhost/Main?ScreenId=GL201500&LedgerCD=0915ACT Is it possible to delete a Ledger through the Web Service?  The problem is we have many ledgers we setup and we want to programmatically delete them.    We would also like to use the same code to do batch cleans of items we no longer want instead of manually deleting items. Thanks in Advance Mark

Hello Everyone,I’m trying to use OpenAPI to connect to Acumatica.To follow below guideline to login Acumatica. I got a error message. https://help-2019r1.acumatica.com/Help?ScreenId=ShowWiki&pageid=0322492a-de9b-4443-b256-923c48aff31d Does anyone know how to fix it? I tried to post to http and https. Both returned same message. Error message:{    "message": "The requested resource does not support http method 'GET'."}

Using a an Azure Classic Cloud Service, we are making REST API calls to a 2020R2 instance (default endpoint), using a token granted through a Connected Application. So for each API request, we are including the “Bearer” header with the access token. This access token was acquired by a different system and sent to the cloud service to process an import/export of data. (The cloud service makes no “login” request, requests with username/password, no “logout” request, no token renewals)When exporting data TO the Acumatica instance, depending on the amount of data to be executed, we make 25-1000+ API calls to that instance (checking if a record exists, if not creating the record. Also checking dependencies).Issue: In the middle of an export process, we experience a failed call with a HTTP Status Code 401 returned with the following data:{"message":"You are not logged in."}This occurred after checking the status of a long-running ReleaseBill Action. This is the order of requests:GET /entity/

We Add Customer Payments through Acumatica’s Screen Based API (We use Authorize.NET’s Customer Information Manager for processing).  It works fine for a customer’s first payment method.  When we attempt to add a new Payment Method (Same CustomerProfileId but different PaymentProfileId), it doesn’t throw an exception but it does not add.  It returns the existing Payment Method Token. Here is my current code:                AR303010Content AR301000 = context.AR303010GetSchema();                context.AR303010Clear();                AR303010Content[] AR303010content = context.AR303010Submit(                    new Command[]                {                    new Value { Value = customerId, LinkedCommand = AR301000.PaymentMethodSelection.Customer },                    new Value { Value = ccType, LinkedCommand = AR301000.PaymentMethodSelection.PaymentMethod },                    new Value { Value = "AUTHNETAPI", LinkedCommand = AR301000.PaymentMethodSelection.ProcCenterID },

Has anyone figured out silent login of Acumatica user? We should be able to pass the user id and pwd to specific URL and auto-login or silent login so it bypasses the login and takes you to specific page to perform certain action and then when we close it logs off, this shld be possible assuming help.acumatica.com works that way.  This feature allows to do lot of things within the framework and allows to scale for online approvals or proofing etc. Any hacks or thoughts, pls share.
