It covers the data transfer flows, file format and transfer protocols.File Transfer ProtocolsAvarala supports two types of transfer protocols: AS2 and SFTP.SFTPTo connect to Avalara SFTP server, you’ll need to generate a public/private key pair. Provide Avalara with the public key and add the private key to your client software. Avalara will supply you back a user name and the SFTP URL. After connecting to the SFTP server you’ll have access to two directories. Upload the requests for classification (product and category files) in the “inbound” directory. The processing errors (if any) and the classification results will be available in the “outbound” directory.AS2To connect to Avalara AS2 server you’ll need to exchange the following information with us:AS2 Identifier AS2 Certificate - for encryption and signing the data AS2 endpoint - comprised of IP address, port and a URI Avalara supports only synchronous MDN.You’ll have to send us all requests for classification via products/category files in json, excel or csv format. In return Avalara will send back the processing errors (if any) and the classification results using the same format we received your requests.File Formats and Naming ConventionAvalara supports json, Excel and CSV as formats for data request and response.File extensions must be according with the file format: json for json files, xlsx for Excel and csv for CSV files.All request file names must start with “HSCR.V2.”. Example: HSCR.V2.GRG009_CA.jsonResponse file names (classifications) start with “HSCR.CLASSIFICATION.V2.”.HS Classification RequestAll requests for HS classification should be sent to Avalara in files using one of the supported formats: json, csv or Excel. File format will be setup when the customer enrolls for the service. Once setup is complete, a customer can only use the chosen format. One file can contain one or multiple requests. Each request must follow the specifications defined for HS Classification Model. In case a request for HS Classification is invalid and cannot be processed, Avalara will generate a response file with the errors.HS Classification ResponseAfter a product was classified the response will be sent back to customer using the same format customer opted for. One file can contain one or multiple responses. The response follows specifications defined for HS Response Model.Models HS Classification ModelFieldTypeDescriptionErrorsIdString(1000)Response OnlyA unique id generated by Avalara Classification System.itemItemModelRequiredProduct detailsValueRequiredError (5)countryOfDestinationString(2)RequiredCountry of destination code (ISO 3166-1 alpha-2).ValueRequiredError (5)InvalidCountry (125)hsCodeString(20)Response Only This is the HS classification result. statusString(20)Response OnlyThis value is returned in the response only and it’ll be ignored if it’s provided in the request. CLASSIFIED - the item was classified, and an HS code was assigned. In this case the hsCode field is not NULLCANNOT_BE_CLASSIFIED – the item cannot be classified based on the information provided. A more detailed explanation is provided in the resolution field. The hsCode is NULL.resolutionString(1000)Response OnlyThis value is returned in the response only and it’ll be ignored if it’s provided in the request. A resolution is returned only if an item cannot be classified (status=CANNOT_BE_CLASSIFIED). It contains a detailed description of the issue.

This is the full path to the category where item is included. Categories should be separated by “ > “. Please note that each category (breadcrumb) should not exceed 100 characters. Multiple category paths per item are accepted. In this case, category paths should be separated by “;”.Example: Sports & Outdoors > Exercise & Fitness > Wearable Technology > Fitness TrackersValueRequiredError (5)classificationParametersArray of ItemParameterModelOptionalList of item parameters use for classification.parametersArray of ItemParameterModelOptionalList of item parametersItem Parameter ModelFieldTypeDescriptionErrorsnameString(255)RequiredThe parameter’s name.The system has predefined a list of parameter names that are known and processed accordingly: See the Parameters List tableParameterRequiredError (3000)valueString(1000)RequiredThe parameter’s value.unitString(255)OptionalThe unit of measurement code for the parameter.
