TWODValidation Filter

The TWODValidation Filter is used for calling the TrustWeaver On Demand service that validates the digital signatures of e-invoices.

Note:

To be able to specify the document format using the Default option, you must define the StrsSignatureFilterOriginalContentType metadata, see Defining document types with metadata.

The TWODValidation Filter

The settings are described in the table below.

Setting	Description
Service type	The type of web service that produces and validates the digital signature. TrustWeaver E-invoice test environment – Used during the development and testing phases. Does not produce legally binding digital signatures. TrustWeaver E-invoice production environment – Used during the production phase. Produces legally binding digital signatures.
Proxy host	The name of the proxy server (if StreamServer connects through a proxy server when calling the TrustWeaver service).
Proxy port	The port used by the proxy server.
Logon credentials	The security configuration resource containing the logon credentials and password.
Document format	The document format of the signed e-invoice to be validated. You can use the Default option, select a specific document format, or specify the document format using a variable. Default – The document format is mapped against the original content type of the invoice before it was signed (“content type – Document format” in the list below): • application/pdf – PDF • text/xml – XML or cXML (if cXML is included in the root node) • application/xml – XML or cXML (if cXML is included in the root node) • For any other data – GENERIC PDF – Used when the format of the e-invoice is PDF. CXML – Used when the format of the e-invoice is cXML (commerce XML). XML – Used when the format of the e-invoice is an XML format other than cXML. GENERIC – Used when the e-invoice is treated as binary data and has any format.
Seller’s tax country code	The name of the variable that contains the country code of the country where the Seller is registered for VAT. For example: $sellerscode The country code must be two characters long and comply with the ISO 3166 standard. The country must be TrustWeaver compliant.
Buyer’s tax country code	The name of the variable that contains the country code of the country where the Buyer is registered for VAT. For example: $buyerscode The country code must be two characters long and comply with the ISO 3166 standard. The country must be TrustWeaver compliant.
Signature type	The type of signature. Normal – Creates legal, country compliant e-invoices with a protection level based on the CAdES-A or XAdES-A profile, intended for B2B (business-to-business) scenarios. This option should normally be used. Simple – Creates legal e-invoices with a protection level based on the CAdES-T or XAdES-T profile. This option can be used in certain B2C (business-to-consumer) scenarios for signing invoices to be sent to the Buyer. A faster signature is used, but there is no evidence that the e-invoice was validated upon reception and there is no long term validation information stored with the signature. To ensure a correct validation over time, the Seller must still archive a copy signed with the Normal option.
	Using Signature type > Simple affects the signature applied. If you are uncertain of the protection level requirements, always use Signature type > Normal.
Agreement identifier	Use if different agreements are used for different signing requests. A text string that associates each signing request with an agreement. You can use variables. For example, if different pricing models are used for different types of signing requests, this setting can be used to identify the requests. The agreement identifier can: • Contain a maximum of 256 characters. • Only contain the letters A to Z (uppercase or lowercase), digits, hyphen, @, dot and underscore.
Content type	Use if a driver is not selected for the output connector. For example, when using RedirectOUT. The content type to be used for the final delivery. For example, application/pdf. You can configure a specific content type, or you can configure the content type using a variable. Note: This content type overrides any content type derived from a driver.
