DebiCheck

DebiCheck is an authenticated debit order system that requires customers to electronically confirm mandate details before collections can be processed.

‍

Overview

DebiCheck provides:

• Reduced disputability: Authenticated mandates are harder to dispute
• Higher success rates: Early processing window priority
• Account tracking: Monitor accounts for up to 10 days post-action date
• Electronic mandate storage: Banks store authenticated mandates

‍

How DebiCheck Works

1. Mandate Creation: Submit the mandate request with the customer details
2. Authentication: Customer receives and approves the mandate via their bank
3. Confirmation: Mandate status changes to COMPLETED
4. Collection: Create collections against authenticated mandates

‍

Authentication Types

‍

Real-Time (TT1)

Customer receives an immediate USSD/push notification and must approve within 120 seconds.

‍

JSON

{
  "authenticationType": "REALTIME",
  "realtimeAuthRetries": 0
}

‍

Delayed Real-Time (TT1b)

Mandate is lodged within 60 seconds, the customer has until 20:00 the same day to approve.

‍

JSON

{
  "authenticationType": "DELAYED"
}

‍

Batch (TT2)

Mandate submitted overnight, the customer has until 19:00 the following day to approve.

‍

JSON

{
  "authenticationType": "BATCH"
}

Get Collection Status

Endpoint

GET /v2/collection/debicheck/{collectionId}/status

‍

Cut-off Times

‍

Important: DebiCheck mandates can only be obtained between 06:00 and 20:00 on weekdays.

‍

Account Tracking

DebiCheck supports account tracking for up to 10 days post-action date:

‍

JSON

{
  "trackingPeriod": 10
}

‍

If a collection fails due to insufficient funds, the bank will monitor the account and retry when funds are available.

‍

Best Practices

1. Have a timing plan: Switch to TT2 for authentication outside business hours
2. Handle failures: Implement a fallback to DELAYED_WITHOUT_AUTH
3. Plan for ignores: Follow up with customers who don't respond to authentication
4. Use correct value type: Choose FIXED, VARIABLE, or USAGEBASED based on your use case
5. Set appropriate max amounts: Ensure maxAmountCents covers your needs
6. Submit early: Present collections at least 2 calendar days before collection day
7. Match collection days: Present collections for the authenticated collection day
