Paygate-Integrationen lokal im Browser vorbereiten, testen und analysieren.
Konfigurieren Sie Classic- und REST-Zahlungsabläufe für Hosted Payment Page, Kreditkartenformular und Pay By Link. Erzeugen und prüfen Sie Paygate-URLs, Payloads und Rückmeldungen direkt im Browser. Lokale Logs, Analysewerkzeuge und das Commercial-Dashboard unterstützen bei der Auswertung Ihrer Testläufe.
Dauerhafte App-Daten werden im aktuellen Browserprofil gespeichert. Was die App ablegt und wann Daten bewusst übertragen werden, bleibt transparent.
AES-GCM-verschlüsselte Credential-Profile, optionales Master-Passwort, Sprache, Design, Einstellungen und Lizenzstatus werden im Browserprofil gespeichert.
Maximal 250 Request- und 250 Response-Einträge werden lokal gespeichert; localStorage dient als technischer Fallback. Das Commercial-Dashboard wertet ausschließlich diese Browserdaten aus.
Classic-Daten verlassen die App erst beim Öffnen der Paygate-URL. REST-Requests werden nur erzeugt. Trial-Aktivierung, Callback-Rückleitungen und externe Links sind ausdrücklich ausgenommen.
Eine Commercial License umfasst eine versionierte, deploybare ZIP-Ausgabe zur Installation auf einem eigenen, zugriffsgeschützten HTTPS-Server.
Installationszahl, abgedeckte Versionen, Laufzeit, Änderungen und Weitergabe werden in der schriftlichen Vereinbarung geregelt.

MAC-Validator und Base64-Encoder für Classic-Requests
Prüft, ob ein MAC korrekt berechnet wurde. Die App bildet den HMAC-SHA256 über PayID*TransID*MerchantID*Amount*Currency — auf Wunsch mit Vergleich gegen den MAC aus deinem Request.
Wandelt JSON-Parameter wie credentialOnFile oder browserInfo in Base64 um — mit fertigen Vorlagen für CIT- und MIT-Zahlungen. Dekodieren funktioniert genauso, wenn du einen Base64-Wert aus einem Request lesen möchtest.
Beide Werkzeuge orientieren sich am offiziellen Paygate-Test von Computop — hier findest du das Original und die zugehörige Anleitung.

Hosted Trial und Noncommercial sowie Commercial License mit Self-Hosting
Die PolyForm Free Trial ist als Standard ausgewählt, wurde aber noch nicht aktiviert.

Für Nutzungen, die unter die nichtkommerziellen Zwecke der PolyForm Noncommercial License 1.0.0 fallen. Die lokale Auswahl ersetzt keine Prüfung der tatsächlichen Nutzung.
Zur Evaluierung, ob die App für einen konkreten Anwendungsfall geeignet ist, für weniger als 32 aufeinanderfolgende Kalendertage. Die Lizenz erlaubt keine Weitergabe von Kopien.
Für produktive, kommerzielle oder kundenbezogene Nutzung inklusive versionierter, deploybarer ZIP-Ausgabe. Installationen, Versionen, Laufzeit, Änderungen und Weitergabe regelt die schriftliche Vereinbarung.
Hier finden Sie beide PolyForm-Lizenztexte, die Commercial- und Self-Hosting-Hinweise sowie die Bedingungen der Drittanbieter.

The hosted Paygate Payment Tester remains available under PolyForm Free Trial 1.0.0 or PolyForm Noncommercial 1.0.0. Commercial use and self-hosting require an individual written Commercial License.
| Version | License |
|---|---|
| Up to and including v3.6.8 | MIT License supplied with those releases |
| v4.0.0 and later | PolyForm Noncommercial 1.0.0 or PolyForm Free Trial 1.0.0 for eligible hosted use; Commercial License for commercial use and self-hosting |
PolyForm Free Trial is the default choice for the hosted app. Before use, the in-app dialog requires activation, import of an existing signed license file, or confirmation that the actual use meets the PolyForm Noncommercial terms. Commercial rights require a separate written agreement.
Every issued Commercial License includes a versioned, deployable ZIP package of the static application for installation on the licensee's own access-restricted HTTPS server. The written agreement defines covered versions, installations, users, term, customer use, modifications and redistribution. A customer-specific .paytest-license file is delivered separately from the generic deployment package.
The Commercial License does not promise repository access, development history, build tooling or an additional source package.
New Request and Response Log records store the selected license status, license ID and a masked Trial email. The full email address and activation token are not stored in logs. This technical label does not verify ownership of the submitted email or create additional rights.
To request commercial terms, contact the copyright holder through martin-krebs.eu.
The project license applies only to original application code for which the copyright holder can grant rights. Third-party libraries, trademarks, logos, fonts and other brand assets retain their own terms and are not covered by a Commercial License unless a written agreement expressly says otherwise.
This document is an operational overview and not a substitute for the applicable license text or an individually signed agreement.
This notice does not itself grant a license.
Commercial, production or service-provider use requires an individual written Commercial License issued by the copyright holder. It may be issued with or without a fee and identifies the holder, license ID, covered versions, permitted scope and term.
