DvPayLite Deep Linking Integration - URI Mode

Version History

Request TPN

To onboard as a merchant and test with the sandbox environment, contact your Dejavoo representative to obtain a TPN (Terminal Profile Number).

What is TPN?

TPN is a 12-digit numeric code assigned to merchants for integration purposes.

Set Up the Developer Environment

1. Android Studio IDE

Download and set up Android Studio from developer.android.com (opens in a new tab).

2. Develop an Android Application

• Create a new Android project or use an existing one.
• Follow the steps outlined below:
  • Set the scheme as "denovopay" when creating the URI.
  • Update the host based on the type of transaction.
  • Refer to the Perform Transaction API section in this document for transaction types and sample input requests.

Install DvPayLite Application

Ensure the DvPayLite application is installed on the payment terminal. If it is not installed, complete the installation before proceeding with the integration.

Version Control and Updates

Non-Breaking Changes

• We will continue to enhance the API by adding new functionality and fixing bugs over time.
• These updates may include:
  • New endpoints
  • Additional attributes for existing objects
• Such changes will not require a new API version. Ensure your code can handle new attributes gracefully and does not rely on the order of returned records unless explicitly specified in the documentation.

Breaking Changes

• We aim to maintain the current API version for the foreseeable future.
• In the event of changes that break the current API's functionality, a new version number will be released to ensure backward compatibility with existing integrations
• Refer to the Version History to review the version history of this document.

High-level flow

The following is a high-level flow to communicate with the DvPay Lite Application.

APIs

Device Register API

The Device Register API is used to download terminal and merchant configuration data from the backend application into the DvPayLite application.

Intent will return transactionResult in the activity result.

Request Parameters:

Response Parameters:

Response(transactionResultJson) Details:

Go Live Requirements

The following are the Go Live activities:

• All third-party app integrations with DvPay Lite via deep-linking will be hosted in our DvStore application, which is provided as a default app in the firmware of production terminals.
• To host an application in the app market, please contact the Dev Support team using the email provided below.
• Once the application is hosted in the DvStore app, it can be downloaded to terminals and updated by hosting newer versions of the app.
• Applications can be tested in test environments before being uploaded to production environments.
