Schnellstart: Ihre erste Testrechnung

Vom neuen Konto bis zur ersten Testrechnung aus Ihrem eigenen Code. Sie brauchen dafür nur eine E-Mail-Adresse und den HTTP-Client Ihrer Programmiersprache.

Anmelden
Melden Sie sich unter /login mit Ihrer E-Mail-Adresse an. Wir senden Ihnen einen einmaligen Code per E-Mail. Ist die Adresse neu, legt die Anmeldung Ihr Konto an.
Den Einrichtungsassistenten durchlaufen
Der Assistent fragt nacheinander nach Ihrer Organisation, dem Rechnungssteller, Layout und Nutzungsbedingungen und dem Logo. Zum Schluss erstellt er einen Test-API-Schlüssel. Kopieren Sie den Schlüssel sofort: Er wird nur einmal angezeigt.
Die Vorlagen-ID ermitteln
Die ID steht im curl-Befehl am Ende des Assistenten. Sie können sie auch mit dem Test-API-Schlüssel abfragen: GET /v1/templates liefert jede Vorlage mit ihrer id. Nehmen Sie eine Vorlage, die eine profileId hat. Eine Vorlage ohne Profil beantwortet den Aufruf mit 404 „Template has no associated profile“.

Die erste Rechnung erzeugen

Senden Sie den Rechnungsdatensatz an diesen Endpunkt, mit einem eigenen Idempotency-Key für jede Rechnung. 201 heißt: Die Rechnung wurde erzeugt. 200 heißt: Derselbe Schlüssel kam schon einmal, und Sie erhalten die bereits erzeugte Rechnung zurück.

POST /v1/templates/{id}/invoices

Der Datensatz enthält weder Verkäufer noch Bankverbindung: Beides ergänzt das Rechnungsprofil der Vorlage. Was Sie im Datensatz mitsenden, hat Vorrang vor dem Profil.

Laden Sie die Dateien unter outputs[].url bald herunter, denn die Links laufen ab. Neue Links erhalten Sie jederzeit mit GET /v1/invoices und der id der Rechnung.

Derselbe Aufruf in Ihrer Sprache

Ein SDK brauchen Sie nicht. Jedes Beispiel nutzt den HTTP-Client, den die Sprache mitbringt, und liest Schlüssel und Vorlagen-ID aus den Umgebungsvariablen INVOICEAPI_KEY und TEMPLATE_ID. Das Python-Beispiel setzt einen eigenen User-Agent, weil ein Aufruf mit dem Standard-User-Agent von urllib mit 403 abgewiesen wird.

Ausgabeformate
Ohne Angabe erzeugt die API eine ZUGFeRD-PDF. Mit ?output= wählen Sie selbst; der Parameter lässt sich wiederholen, etwa ?output=zugferd_pdf&output=xrechnung_xml.
zugferd_pdf
Die Voreinstellung: PDF/A-3 mit eingebettetem XML, geprüft mit dem KoSIT-Validator und veraPDF.
xrechnung_xml
Das XML für öffentliche Auftraggeber, geprüft mit dem KoSIT-Validator. Es braucht BT-10 (invoice.buyerReference), BT-34 und BT-49 (die elektronischen Adressen von Verkäufer und Käufer). BT-10 und BT-49 stehen im Datensatz oben, BT-34 kommt aus dem Rechnungsprofil der Vorlage.
pdf
Die einfache PDF, ohne Prüfung.
Mögliche Antworten auf den ersten Aufruf
Fehler kommen als application/problem+json mit dem englischen Titel der API.
401 Invalid or missing API key
Der Schlüssel fehlt, ist unbekannt oder wurde widerrufen.
404 Template not found
Die Vorlagen-ID ist falsch oder gehört nicht zu Ihrer Organisation.
404 Template has no associated profile
Die Vorlage hat kein Rechnungsprofil. Nehmen Sie eine Vorlage mit profileId.
400 Invalid invoice payload
Der Datensatz passt nicht zum Schema. errors nennt jeden fehlerhaften Pfad mit seiner Meldung.
400 Payload is not XRechnung-ready
Sie haben xrechnung_xml angefordert, aber im Datensatz fehlt BT-10, BT-34 oder BT-49.
422 Invoice failed compliance validation
Die Rechnung hat die Prüfung nicht bestanden. errors nennt jede verletzte Regel mit ihrer ID, etwa BR-DE-15.

Endpunkte

POST/templates/{id}/invoices

Generate an invoice from a template

Generates a ZUGFeRD PDF/A-3, an XRechnung XML and/or a plain PDF from the template and payload (see the `output` parameter for which checks each kind gets). Idempotent per Idempotency-Key: a repeat with the same key and an identical body replays the original invoice with a 200 instead of creating a new one. Supply the optional `deliverEmail` block to also email the finished invoice: delivery is attempted synchronously and its outcome is reported on the 201, but a delivery failure NEVER fails the request — the invoice is archived either way. The seller and the bank details (`iban`, `bic`, `accountName`) come from the template's invoice profile for every field the request leaves out; a field the request sends wins.

Parameter

Feld	Ort	Erforderlich	Beschreibung
id	path	Erforderlich	Resource id.
output	query	—	Repeatable. Which artifact kind(s) to produce. Defaults to zugferd_pdf when omitted. `zugferd_pdf`: a PDF/A-3 with the ZUGFeRD XML embedded; KoSIT checks the XML and veraPDF checks the PDF/A-3U. `xrechnung_xml`: the XRechnung XML, checked by KoSIT only; it needs BT-10 (`invoice.buyerReference`), BT-34 (`seller.electronicAddress`, usually from the template's profile) and BT-49 (`buyer.electronicAddress`), or the request gets a 400 "Payload is not XRechnung-ready". `pdf`: the rendered PDF only, with no embedded XML and no KoSIT or veraPDF check (the renderer's plain PDF, NOT validated), so an invoice that requests only `pdf` has an empty `validation.summary`.
Idempotency-Key	header	—	Client-supplied key. A repeat with the same key and body returns the original invoice (200); the same key with a different body returns 409.

Antwort

200application/json

Idempotency-Key replay: the invoice already generated for this key and body. A replay NEVER sends email and never reports delivery — the `deliverEmail` field is absent, even if the replayed request carried a `deliverEmail` block. The original request owns the delivery; consult the invoice to see its state.

400application/problem+json
Malformed payload or deliverEmail block (schema validation failed, after the template's profile filled in the seller and bank details); an unknown `output` kind; or "Payload is not XRechnung-ready" when `xrechnung_xml` is requested without BT-10, BT-34 or BT-49.
401application/problem+json
Missing or invalid API key (Authorization: Bearer <key>).
402application/problem+json
Monthly quota exceeded (only enforced when billing is enabled).
403application/problem+json
Recipient not allowed (`https://invoiceapi.io/problems/recipient-not-allowed`): on the Free plan `deliverEmail` may address only members of your organization, in `to` and `cc`; customers from Starter. Checked before generation, so the request uses no document. Only enforced when billing is enabled.
404application/problem+json
Template, template version, or profile not found.
409application/problem+json
Idempotency-Key reused with a different request body.
422application/problem+json
Compliance validation failed (KoSIT / veraPDF findings: each `errors[]` entry names its engine in `source`; the example is a veraPDF rejection), or a live invoice carries the sample seller VAT ID or IBAN (type https://invoiceapi.io/problems/sample-seller-data). To fix the latter, remove `seller` and the bank details (`payment.iban`, `bic`, `accountName`) from the request so the template's profile fills them, or send your own values; if the profile itself carries the sample data, fix it under /profiles.
