# Incoming dataset
|
|
|
|
Copy the challenge dataset to this directory as `challenge_data.csv.gz` before running the future importer. The archive is intentionally ignored by Git.
|
|
|
|
Expected source columns:
|
|
|
|
```text
|
|
session_key, try_seq, terminal_key, merchant_key, category_id,
|
|
category_title, amount, adjusted_fee, session_status, try_status,
|
|
switch_response_code, psp_code, issuer_bank_code, payer_card_key,
|
|
verify_type, init_time_ms, verify_time_ms, created_at, try_created_at,
|
|
verified_at, settled_at, expire_in
|
|
```
|
|
|
|
Do not add merchant passwords or other secrets to this directory. Demo credentials will be generated/seeding inputs managed separately through secure environment or one-off administrative workflows.
|
|
|
|
The source contains session markers where `try_seq = 0` and `try_status = NoAttempt`. The importer must create the session but no normalized payment-attempt row for these records.
