Create a Credit Memo

By using the REST API, you can create a credit memo in MYOB Acumatica. You can view this credit memo on the Invoices (SO303000) form.

System Preparation

Before you test the code below, you need to do the following to configure your client application and the MYOB Acumatica instance to be used:

Deploy a new MYOB Acumatica instance with the U100 dataset. For details on deploying an instance, see Instance Deployment: To Deploy an Instance with Demo Data.
On the Enable/Disable Features (CS100000) form, make sure that the Inventory and Order Management feature is enabled.
If you are using Postman as the client application for testing, in the IntegrationDevelopmentGuide.postman_collection.json collection, make sure that the collection’s variables have the proper values. This collection is located in the IntegrationDevelopment\Help folder of the Help-and-Training-Examples repository on GitHub.
To sign in to the instance in the client application, use the tenant name (which you specified when you created the instance) and the HEADOFFICE branch.

Request

You can use the following request example to create a credit memo through the REST API. This credit memo will be created for the return of the following:

All units of the item listed in the 000005 invoice
All units of the item listed in line 1 of the 000008 invoice
50 units of the item listed in line 2 of the 000012 invoice

Tip: In the request example below, <MYOB Acumatica host> is the URL of the MYOB Acumatica host (such as https://my.acumatica.com). You need to use the instance name in the URL of the request (such as https://my.acumatica.com/MyInstance) if the instance is not installed in the root of the website.
