Everything your agent can do with HelloSign and Factur-X by InvoiceXML ## Triggers and actions 1 trigger · 18 actions - Trigger **New Signature Request** Triggers when a new signature request appears in the account. - Action **Cancel Signature Request** Cancels an incomplete signature request. - Action **Get Account** Returns information about the current Dropbox Sign account. - Action **Get Signature Request** Retrieves a single signature request by its ID. - Action **Get Signature Request Files** Returns a download URL for the documents of a signature request as a PDF. - Action **List Signature Requests** Lists signature requests for the account, paginated and ordered newest first. - Action **List Templates** Lists the reusable templates available to the account. - Action **Send Reminder** Sends an email reminder to a signer to sign a pending signature request. - Action **Send Signature Request** Creates and sends a new signature request using document file URLs and a list of signers. - Action **Convert CII XML to Factur-X** Converts a CII XML invoice into a Factur-X compliant PDF/A-3 with the XML embedded. The API generates a visual PDF rendering of the invoice and packages it with the source CII XML. - Action **Convert Factur-X PDF to CII** Extracts the embedded CII (UN/CEFACT Cross Industry Invoice) XML from a Factur-X PDF and returns it as a standalone XML file. - Action **Convert Factur-X PDF to UBL** Extracts the embedded CII XML from a Factur-X PDF and converts it to UBL (Universal Business Language) XML. - Action **Convert UBL XML to Factur-X** Converts a UBL XML invoice into a Factur-X compliant PDF/A-3. The API maps UBL to CII, generates a visual PDF rendering, and embeds the CII XML in the PDF/A-3 container. - Action **Create Factur-X Invoice** Builds a Factur-X invoice from structured header, party, payment, and line-item data, then returns a ready-to-deliver PDF/A-3b file. - Action **Embed XML Into PDF (Factur-X)** Takes a PDF and a CII XML and produces a Factur-X compliant PDF/A-3 with the XML attached as factur-x.xml. Use this when you already have both the visual PDF and the structured XML of an invoice and just need the hybrid wrapper. - Action **Extract Invoice JSON** Pulls invoice fields from a PDF into structured JSON, preferring embedded Factur-X XML when present and falling back to intelligent extraction when not. - Action **Extract Invoice XML** Retrieves machine-readable invoice XML from a PDF, returning embedded Factur-X XML directly or generating compliant XML when none is embedded. - Action **Render CII as PDF** Renders a CII (UN/CEFACT Cross Industry Invoice) XML document into a human-readable PDF. The output is a visual PDF, not a Factur-X hybrid file. - Action **Validate Factur-X Invoice** Checks whether a Factur-X invoice is structurally and semantically valid, including schema status, conformance level, and rule-level issues. ## Each app on its own - [ **HelloSign** Dropbox Sign (formerly HelloSign) e-signature platform.](https://apiant.ai/connections/hellosign) - [ **Factur-X by InvoiceXML** Factur-X by InvoiceXML is an e-invoice automation: create, transform, validate, and extract Factur-X PDFs...](https://apiant.ai/connections/factur-x-by-invoicexml) Reviews ## What our customers say ## More from HelloSign - [ **HelloSign to Salesforce** Salesforce is a leading enterprise customer relationship management (CRM) platform.](https://apiant.ai/connect/hellosign-to-salesforce) - [ **HelloSign to Slack** Slack is a messaging platform for teams.

Any of HelloSign's 1 trigger in the catalog, including New Signature Request. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Factur-X by InvoiceXML when something happens in HelloSign? Any of Factur-X by InvoiceXML's 10 actions, including Create Factur-X Invoice, Convert CII XML to Factur-X, Convert Factur-X PDF to CII and Convert Factur-X PDF to UBL. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Factur-X by InvoiceXML to HelloSign? Factur-X by InvoiceXML has no triggers in the catalog today, so automations start in HelloSign. If you need the other direction, ask: your agent reads Factur-X by InvoiceXML's API documentation and adds it. ### ### Do I have to build a connector for HelloSign or Factur-X by InvoiceXML? No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running. ### ### Can my AI client use HelloSign and Factur-X by InvoiceXML without building an automation? Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
