Sandbox PayWise App (APK)

Use the Sandbox PayWise mobile app to test wallet payments, deep links, and end-to-end checkout flows in sandbox.

This is not Account API access​

Installing or signing into the Sandbox App does not grant your project direct Account API access (/account/*).

For the full sandbox account journey (portal provisioning vs api_key vs Account API approvals), see:

  • /getting-started/sandbox-account-setup

Download​

If your browser blocks the download, allow downloads for the PayWise docs site and try again.

Install (Android)​

  1. Download the APK.
  2. Open the downloaded file on your Android device.
  3. When prompted, allow installation from unknown sources for your browser/file manager.
  4. Complete the install and open the app.

Sign in (Sandbox)​

  • OTP: 123456

The Sandbox App is recommended before sending payment requests because push notifications and payment-request delivery may require the business user to have logged into the app at least once.

If payment requests are created successfully but the app never receives them, confirm the user has signed in at least once and that you are using the correct sandbox business api_key.

OTP scope

123456 is the default OTP for Sandbox App OTP prompts only. It does not apply to PayWise Identity / admin portal MFA.

Mint a business api_key (in the app)​

After you create a sandbox business test account, open:

  • Settings → API

Mint a business api_key. You will use this key in the body of POST /payments/request.

For sandbox business accounts created in the Developer Portal, the business api_key is also shown in the account credentials area. Settings → API in the app may also show API credentials where supported.

Keys: pw-subscription-key vs api_key​

  • pw-subscription-key goes in the request header (for all API calls).
  • api_key goes in the JSON body for payments endpoints like POST /payments/request.

Going live after sandbox​

After you’ve validated your integration in sandbox, follow the production checklist before sending live payments:
