# Chapter 4.3.8 - Sales and Use Source: https://developer.avalara.com/products/communications/integration-guides/dev-guide_rest_v2/customizing-transactions/sample-transactions/sau/ - [Previous](/communications/dev-guide_rest_v2/customizing-transactions/sample-transactions/safe-harbor-override/) - [Next](/communications/dev-guide_rest_v2/customizing-transactions/sample-transactions/sau-attribute-property/) Communications REST v2 returns Sales and Use taxes in addition to communications taxes. On an SAU transaction: - Use the [`/api/v2/afc/tspairs` endpoint](/communications/dev-guide_rest_v2/getting-started/environments-endpoints#lookups) to find a list of Sales and Use Transaction/Service Pairs - Set [Attribute Property](/communications/dev-guide_rest_v2/customizing-transactions/sample-transactions/sau-attribute-property/) (`prop`) - Specify the [jurisdiction(s)](/communications/dev-guide_rest_v2/reference/location/) - Set the common characteristics of a transaction, such as charge (`chg`), invoice date (`date`), and sale type (`sale`) - Include any additional information, such as tax overrides (`ovr`) and exemptions (`exms`) ### Property and Attributes An SAU transaction requires that an attribute and properties are set to describe the transaction in more detail. - An Attribute refers to ancillary transactions related to the actual sale. For example: - installation - Maintenance and service contracts - Warranties - Properties specify the details of the transaction’s Attribute Set Attribute Property (`prop`) to the ID of the property and attribute combination. See [SAU Attributes and Properties](/communications/dev-guide_rest_v2/customizing-transactions/sample-transactions/sau-attribute-property/) for a list of valid attribute and property combinations. ### Sales and Use Example Sales and Use Transaction/Service Pairs (`tran` and `serv`) are used. ```json { "cmpn": { "bscl": 0, "svcl": 0, "fclt": false, "frch": false, "reg": false }, "inv": [ { "doc": "TEST-SAU INVOICE", "cmmt": false, "bill": { "cnty": "San Francisco", "ctry": "USA", "int": true, "geo": false, "city": "San Francisco", "st": "CA", "zip": "94102" }, "cust": 0, "lfln": false, "date": "2018-05-01T12:00:00Z", "itms": [ { "ref": "Line Item 001 - Retail Sale General Merchandise/General Rule Default Attribute-Property", "chg": 100, "line": 0, "sale": 1, "incl": false, "tran": 34, "serv": 106, "prop": 0, "dbt": false, "adj": false }, { "ref": "Line Item 002 - Consumer Use General Merchandise/General Rule Discount Attribute-Cash Discount Property", "chg": 100, "line": 0, "sale": 2, "incl": false, "tran": 34, "serv": 106, "prop": 13, "dbt": false, "adj": false }, { "ref": "Line Item 003 - Vendor Use General Merchandise/General Rule Discount Attribute-Coupons Third Party Property", "chg": 100, "line": 0, "sale": 3, "incl": false, "tran": 34, "serv": 106, "prop": 7, "dbt": false, "adj": false } ], "invm": true, "dtl": true, "summ": true, "opt": [ { "key": "1", "val": "SAU Sample Line Items Invoice ABC-ZZZ" } ] } ]} ``` #### Response Sales and Use taxes, identified by the **SALES AND USE TAXES** category (`cat`), are returned.
