Testing

The Revio sandbox environment provides a mock-bank infrastructure for comprehensive testing.

‍

Overview

The sandbox allows you to:

• Test mandate creation, collections, and payments
• Simulate bank processing and status changes
• Test error scenarios and edge cases
• Verify webhook integrations

‍

Getting Started

Request Test Credentials

Contact Precium at support@precium.com to request sandbox credentials:

• client_id (username)
• client_secret (password)

‍

Test Resources

‍

Test Merchant Profile

Use this pre-configured profile for sandbox testing:

‍

Mock Bank Simulation

The mock bank simulates real bank processing, including:

• Status changes (PENDING → COMPLETED/UNPAID)
• Business rules enforcement
• Response file generation

‍

Simulation Scenarios

‍

EFT Collection Test Scenarios

Use specific account numbers to simulate different outcomes:

‍

Account Number Scenarios

‍

Example: Test Unpaid Collection

BASH

curl -X POST https://dev.api.revio.co.za/v2/mandate/eft/ \
 -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
   "debtor": {
     "accountNumber": "110000002",
     ...
   },
   ...
 }'


‍

DebiCheck Mandate Test Scenarios

Use specific contract references to simulate authentication outcomes:

‍

Contract Reference Scenarios

‍

Example: Test Rejected Mandate

BASH

curl -X POST https://dev.api.revio.co.za/v2/mandate/debicheck/ \
 -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
   "contractReference": "REJECT",
   "authenticationType": "REALTIME",
   ...
 }'


‍

Example: Test No Response

BASH

curl -X POST https://dev.api.revio.co.za/v2/mandate/debicheck/ \
 -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
   "contractReference": "NORESPONSE",
   "authenticationType": "REALTIME",
   "fallbackAuthenticationType": "DELAYED_WITHOUT_AUTH",
   ...
 }'


‍

Webhook Testing

Simulate Status Changes

Test callback handling by simulating status changes:

‍

BASH

curl -X POST https://dev.api.revio.co.za/v2/callback/test/collection/eft/{collectionId}/ \
 -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
   "collectionStatus": "UNPAID",
   "callbackVersion": "V2"
 }


‍

Test with Override URL

Send callbacks to a test endpoint:

‍

BASH

curl -X POST https://dev.api.revio.co.za/v2/callback/test/collection/eft/{collectionId}/ \
 -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
 -H "Content-Type: application/json" \
 -d '{
   "overrideUrl": "https://webhook.site/your-test-id",
   "collectionStatus": "COMPLETED",
   "callbackVersion": "V2"
 }'

Testing Checklist

Mandate Management

• Create EFT mandate
• Create DebiCheck mandate (REALTIME)
• Create DebiCheck mandate (DELAYED)
• Get mandate status
• Amend mandate
• Test authentication failure scenarios

‍

Collections

• Create EFT collection from the mandate
• Create a DebiCheck collection from the mandate
• Get collection status
• Test unpaid scenarios
• Test dispute scenarios

‍

Payments

• Create a same-day EFT payment
• Create a one-day EFT payment
• Create a two-day EFT payment
• Get payment status

‍

Webhooks

• Register callback URL
• Receive collection status callback
• Receive mandate status callback
• Handle all status types

‍

Error Handling

• Invalid authentication
• Missing required fields
• Invalid account numbers
• Duplicate references

‍

DebiCheck Implementation Tips

When implementing DebiCheck, consider:

‍

Client References

Ensure each mandate has a unique contract reference (max 14 characters). This appears on customer bank statements alongside your abbreviated name.

‍

Timing

Plan for authentication outside business hours:

• DebiCheck mandates can only be obtained 06:00-20:00 weekdays
• Consider switching to TT2 (batch) for after-hours onboarding

‍

Managing Failures

• Implement retry logic with realtimeAuthRetries
• Use fallbackAuthenticationType for automatic failover
• Follow up with customers who ignore authentication requests

‍

Mandate Rules

‍

Collection Timing

• Submit collections at least 2 calendar days before the collection day
• Do not adjust for public holidays or weekends (or use allowDateAdjustment)
• Only collect on authenticated mandates

‍

Mandate Management

Consider creating new mandates rather than amending existing ones to avoid complexity in re-authentication scenarios.

‍

Test Data

Valid Test ID Numbers

Use a valid South African ID number format:

• 2001014800086
• 8501015800089
• 4101014800082

‍

Test Phone Numbers

Use format +27-XXXXXXXXX:

• +27-123456789
• +27-615333440
• +27-987654321

Moving to Production

Once testing is complete:

1. Review the Going Live checklist
2. Contact your Revio account manager for production credentials
3. Update your application configuration
4. Perform smoke tests in production

‍

Important: Never use production credentials in sandbox or vice versa.
