How to Use Acumatica API: A Beginner's Guide

Are you an Acumatica consumer looking for task automation or Acumatica integration with other applications? Consider the Acumatica API; it may help! This article refers to Acumatica's Cloud ERP APIs, allowing integration with external systems and applications. Through web services, external applications can get data records from Acumatica, process them, save them, and create new or updated ones.

Understanding Acumatica API

Acumatica API offers the developer and system integrator access to screen-based and contract-based APIs based on SOAP interfaces‍.

REST API: This API allows consumers to access Acumatica data using GET, POST, PUT, and DELETE, all common HTTP requirements. REST API also offers both easy and flexible methods to enter Acumatica data.

Contract-Based API: This API provides consumers with creating and contracts executing functions and forecasting actions, which can be finished in the Acumatica ERP system.

Contract-based API is a more robust and secure option for accessing Acumatica data and performing complex operations.

How to Get Started with Acumatica API

Acumatica Cloud ERP Platform

To begin with, Acumatica API, the Figure above graphically describes these API interfaces between our core ERP product base and third-party applications. The implementation starts differently with different types of API.

Screen-based Web Services API

The screen-based APIs are designed to work with all Acumatica ERP forms by using the fields and actions available on these forms directly. For example, in the form below, each element – a text box, combo box, or table column is associated with a particular web services API class and is available through a corresponding class property. The property has a similar name to the corresponding box on the form.

Step 1: Log into Acumatica

After logging in, you can access the data on the forms available through a simple web service. The screen class of the API methods for working with all Acumatica ERP forms is available.

Step 2: Find out which form a method accesses.

You can find out which form a method access by the prefix in the name of the method, which is the form ID. For example, the Export() method you use to export data from the stock items from the inventory form IN202500 is IN202500 Export().

Screen-based APIs are unique to Acumatica – they offer tremendous value in terms of a set of rich capabilities and great flexibility. However, they are screen-bound, and any change in the screen tends to change the API itself.

Contract-based Web Services API

Contract-based APIs operate with business logic objects not bound to the screen, per se – and their properties and methods. Contract-based APIs are built on an object model that the web services API provides. They do not change based on system customization, localization, or any other changes made to Acumatica ERP, such as forms, for any new development projects from our current partners or your first development project as a new partner should be built using the contract-based APIs.

Step 1: Understanding newly introduced Contract-based APIs in Acumatica

Contract-based APIs operate with business logic objects not bound to the screen, per se – and their properties and methods. Contract-based APIs are built on an object model that the web services API provides. They do not change based on system customization, localization, or any other changes made to Acumatica ERP, such as forms.

For example, suppose you wrote some code using the ItemClass field, which accesses the same ItemClass ID element we found in the Inventory form IN2025000 in our screen-based API example. If you change the name of the ItemClass ID element in your customization project, your code remains fully functional and does not require recompilation or any further modifications. You can access the ItemClass ID element on the form through the same ItemClassID field.

Step 2: Checking out Simple Contract-based Code Sample: Retrieving a List of Stock Items

Like the screen-based example in the previous section above, we show how easy it is to retrieve stock. The following code is straightforward and does not reference a screen to retrieve the items.

//Retrieving the list of stock items from inventory 

public static void ExportStockItems() 

{ 

 using (DefaultSoapClient soapClient = new DefaultSoapClient()) 

 { 

 //Log in to Acumatica ERP 

 WebServiceConnector.InitializeWebService(soapClient); 

 try 

 { 

 //Get the list of stock items 

 Entity[] stockItems = 

 soapClient.GetList(stockItemsToBeFound, False); 

 } 

 finally 

 { 

 //Log out from Acumatica ERP 

 soapClient.Logout(); 

 } 

 } 

 }

2. Follow RESTful API conventions.

Acumatica API uses RESTful API conventions, meaning URLs identify resources and perform HTTP operations. Following these conventions when developing your integration is essential to ensure consistency and maintainability.

3. Use the API efficiently

Resources are needed for API calls as they are significant to your application's conduct.

Using the API with efficiency is significant to minimizing the number of calls and advancing the back data of every call. Batching and caching can be used to boost performance.

4. Handle errors gracefully

There are various reasons to fail API calls such as network, server or user errors. Handling mistakes gracefully is essential by providing informative error messages and taking appropriate action based on the error type.

5. Test your integration

Testing is crucial to the development process to make sure that your assimilation meets the requirements and works as expected and. Test your integration thoroughly using different scenarios and edge cases to identify and address issues.
