01 · What you get

What a SFTP Connector integration gives you.

Predictable data freshness

Analytics teams know when each export lands and can schedule dashboard refreshes and reporting cadences accordingly. Warehouse pipelines run on a stable clock.

Resilient batch handoffs

Failed file transfers or malformed data trigger alerts and quarantine logic before ERP reconciliation breaks. Teams can respond within the same business day.

Governed data schemas

Each export is documented with field mappings, validation rules and version markers. Schema changes are communicated and tested before they affect downstream consumers.

Audit trail and compliance

All exports are logged with timestamps, checksums and content lineage. Compliance teams can prove data integrity for regulatory reporting and discovery.

02 · When it's worth it

Where a SFTP Connector integration earns its place.

If two or more of these are true, the integration usually pays for itself quickly.

Daily order exports to ERP or fulfilment system
Scheduled catalogue and pricing feeds to marketplaces or distribution partners
Analytics event extracts feeding a data warehouse or BI platform
Inbound supplier product data and cost updates
Compliance and audit report generation and archival
03 · The limits

Where off-the-shelf connectors fall short.

Vendor connectors are fine for simple cases. Here's where the real ones need more.

No realtime signalling

SFTP relies on polling or cron schedules. Urgent data changes (price drops, stock corrections, fraud alerts) are delayed until the next batch window, which can be hours or days.

Manual exception triage

Rejected or malformed files drop into quarantine without automatic remediation. Teams must manually inspect logs, fix source data and rerun exports, creating queue backlog during peak periods.

No built-in schema versioning

File format changes require coordination across all producers and consumers. Drift between schema versions can cause silent data loss or parse failures without explicit validation.

Limited observability

Standard SFTP logs show file transfer success but not data validity or downstream impact. Detecting stale extracts, duplicate rows or incomplete batches requires custom monitoring.

Idempotency responsibility shifts

Consumers must handle duplicate or partial files themselves; SFTP does not guarantee exactly-once delivery or atomic transactions across multiple file operations.

04 · The real work

Most SFTP failures are silent because teams assume a missing file is just the next batch not due yet, when in fact the extract crashed three days ago.

05 · Where it sits

Where this integration sits in your estate.

SFTP Connector holds the commercial record. The iWeb integration layer manages the rules, mappings, monitoring and exceptions. The commerce platform presents the customer-facing experience. The estate map helps agree ownership before anything is built.

Connect across your stack. SFTP Connector plugs into the systems that run your trading operation, whichever ecommerce platform sits at the front.

07 · Data flows

The data flows we wire.

Each flow has a direction and an owner. We agree both before a line of code is written.

→Into DATA WAREHOUSE & ERP
←From ERP & OTHER SYSTEMS
↔BOTH WAYS
Analytics event ingestion: Commerce events, customer behaviour and transaction records are exported on schedule and dropped to a remote SFTP landing zone for warehouse pipelines to pick up
Freshness depends on batch schedule, not realtime triggers.
Stock and pricing extract: Base pricing, customer-specific rates and stock availability data flow from ERP to a local landing zone, where commerce systems or integrations read and process the files on their own cadence.
Order and customer feed: Validated orders, shipment confirmations and customer account changes are pushed to ERP via SFTP, where ERP batch processes reconcile them against the transactional skeleton.
Catalogue and channel feeds: Commerce exports product data and channel-specific attributes to SFTP; channel or supplier systems push back corrections, costs and availability flags on a scheduled rhythm.
Inbound enrichment data: Third-party data vendors, imagery services and taxonomy providers drop files to SFTP; commerce pipelines consume them to enrich product records or refresh attributes.
08 · How we build it

How iWeb configures the integration around your business.

Same method on every integration. The decisions come before the code.

  1. 01
    Schedule design and load-balancing

    We size batch windows to avoid peak commerce traffic and coordinate overlapping exports across multiple systems so no single SFTP connection becomes a bottleneck.

  2. 02
    Schema mapping and validation

    We define field mappings, data types and business rules into extract templates. Validation happens before file write so malformed data is caught early.

  3. 03
    Exception handling and alerting

    We build monitored landing zones with quarantine and retry logic. File failures trigger Slack or PagerDuty alerts and create tickets for manual investigation.

  4. 04
    Monitoring and SLA tracking

    We instrument extracts with data-freshness checks, row-count validation and downstream consumption logs. Dashboards show whether each batch met its delivery and completeness SLA.

09 · Ownership

10 · Experienced integrator

Built this before

iWeb has designed and operated SFTP-based data movements across multiple commerce estates. We understand how batch timing, schema governance and exception handling interact with ERP reconciliation cycles and warehouse refresh schedules.

We set extract schedules to avoid peak ERP processing windows and coordinate overlapping jobs so SFTP server and source database do not get starved.
We build quarantine and retry logic so malformed files surface within the same business day, preventing silent data loss in the warehouse or ERP.
We instrument extracts with checksums, version markers and freshness tracking so downstream teams can verify data integrity and audit compliance.
We document schema versioning and communicate changes 2 weeks in advance, giving all producers and consumers time to align test and deploy.
We establish ownership of each export flow (commerce, ERP, analytics) and run weekly synch meetings to review unresolved exceptions and drift.
11 · Before launch

What we test before launch.

Every one of these is rehearsed before a customer ever sees the integration.

Extract produces valid rows and matches expected row count within 2% variance; checksums match on source and destination.
Failed extracts trigger alerts within 15 minutes and create a quarantine file with error reason so manual triage can begin immediately.
Schema changes are tested in isolation before production rollout; downstream consumers are notified and dual-export runs for one week during transition.
SFTP credentials are pulled from a secret manager at runtime, never hardcoded; credentials rotate without requiring scheduler restart.
Landing zone retention policy is enforced; old files are archived to cold storage after 90 days and deleted after 7 years.
File freshness and row-count anomalies are visible on a dashboard; SLA thresholds are set per extract and alert on breach.
Rollback path is tested: if a bad extract ships, previous good version can be restored and re-imported without duplicating data in the warehouse.
12 · Failure points

Common risks and where they bite.

We name these on day one. A risk written down is a risk you can plan around.

Silent extract staleness

Cron jobs fail silently or get starved by competing processes. Consumers continue using yesterday's data without realizing the extract stopped running 48 hours ago.

Schema drift breaking pipelines

A source system adds or removes a field without warning. Downstream parsers fail and leave files in quarantine, halting warehouse ingestion or ERP order import.

Duplicate and partial-file handling gaps

A network interruption leaves a partially written file on SFTP. Consumers see duplicate rows or miss final records if they lack idempotency or atomic-file detection.

Unowned exception queues

Malformed files accumulate in a quarantine folder but no team monitors or retries them. Days later, missing data causes reconciliation mismatches or incomplete reports.

Warehouse pipeline lag masking data issues

Analytics lag is so high that teams attribute stale data to normal refresh delay rather than a broken export. Dashboard bugs go undetected until stakeholders escalate.

14 · Questions

Common questions about SFTP Connector integrations.

How do we guarantee an extract runs on time every day?

Cron jobs should run with a monitoring wrapper that checks execution within 15 minutes of schedule. If no heartbeat is detected, an alert fires to the on-call team. Build a simple health-check endpoint that confirms the most recent file exists and is within SLA age.

What happens if an extract crashes halfway through writing a file?

Write to a temporary file with a locked name, then atomic-rename it only after all rows are written and checksummed. Consumers should skip any file without a matching checksum marker. This prevents partial files from being read.

How do we handle schema changes without breaking downstream pipelines?

Tag each file with a schema version in the filename or header. Document the version mapping in a central registry. Give downstream teams 2 weeks' notice and dual-export both old and new formats during transition if possible.

Should we use SFTP over SSH or unencrypted FTP?

Always use SFTP over SSH. Unencrypted FTP exposes credentials and data in flight. Many compliance frameworks (HIPAA, PCI, GDPR) mandate encrypted transport for any PII or financial data.

How often should extracts run to balance freshness and ERP load?

Run hourly for critical data like orders and stock; daily for analytics events and catalogue enrichment. If ERP throttles large exports, stagger them so no two extracts overlap. Monitor source-system CPU and lock contention.

What should we do if a file is corrupt or contains duplicates?

Land it in a quarantine folder tagged with the error reason and timestamp. Trigger an alert to the integration team. Require manual review and confirmation before reprocessing; never auto-retry corrupted data without human sign-off.

How do we prove data integrity for audit or compliance reviews?

Store checksums, row counts and timestamp metadata alongside each file. Log all access attempts and downloads. Keep an immutable archive of every extract for at least 7 years, with encryption at rest.

Can we use SFTP for realtime data sync or do we need a message queue?

SFTP is not suitable for realtime sync. Use SFTP for batch analytics and bulk data migration. For urgent signals (fraud alerts, inventory corrections, payment confirmations) use event streaming or APIs with sub-second latency.

What monitoring should we set up to catch a stale extract?

Track file arrival time, size, and row count against historical baselines. Alert if a file is missing, arrives late, or has significantly fewer rows than expected. Set different thresholds for peak vs off-peak periods.

How do we handle large extracts that take hours to generate and transfer?

Split extracts by date range or entity type so each file is under 1 GB. Use parallel transfers if your SFTP server supports concurrent connections. Compress before transfer and decompress on landing to reduce network time.

Who owns the responsibility if an order export to ERP fails silently?

Define clear ownership: integration team owns the export logic and alerting; ERP team owns the import pipeline and reconciliation. Hold a weekly synch meeting to review quarantined files and trace ownership of unresolved exceptions.

Should we store passwords and SSH keys in our scheduler or use a secret manager?

Always use a secret manager (Vault, AWS Secrets Manager, Azure Key Vault). Rotate credentials every 90 days. Never commit credentials to source control. Audit all access to secrets in logs.

What is the difference between SFTP and SCP for file transfer?

SFTP is interactive and supports directory listing and partial transfers. SCP is simpler but less reliable for resuming interrupted transfers. Use SFTP for production batch jobs; SCP is fine for ad-hoc scripts.

How do we avoid exporting customer PII by mistake?

Build a PII filter into the extract logic that strips email, phone, address from any non-compliance export. Encrypt SFTP files if they contain PII. Log all PII exports and audit them monthly.
