API Integration & Orchestration

Connect systems properly — with validation, retries, idempotency and an audit trail.

The task

Several systems hold overlapping data and none of them agree. Data is moved between them by scheduled exports, manual imports and a script somebody wrote that nobody maintains, and when it breaks it usually breaks silently.

What it works from

The systems involved and their available interfaces
Which system is authoritative for each entity
Volume, frequency and acceptable latency
Existing scripts and scheduled jobs, including the undocumented ones

The automated workflow

A single authoritative source is agreed per entity — this is a business decision.
Field-level mapping and transformation rules are documented.
Adapters are built per system, isolating each vendor's quirks behind one interface.
Every transfer validates against a schema, and invalid records are quarantined.
Operations are idempotent and retried with backoff, so a transient failure is not a data loss.
Failures alert a named owner, and every run leaves an audit record.

Where a human stays in control

You decide which system wins a conflict; we implement it, we do not guess it.
Quarantined records are reviewed by a person rather than force-imported.
Deletion never propagates automatically across systems without explicit configuration.
Every integration has a named owner on your side, agreed at handover.

Integrations

ERP
Orders, inventory and finance records synchronised through a validated adapter rather than a nightly spreadsheet.
CRM
Read and write deals, contacts and activities so qualified enquiries land where sales already works.
1C
Exchange with 1C configurations through supported interfaces, with reconciliation and a quarantine for bad records.
Microsoft 365
Identity, mail, calendars and document libraries, with permissions respected rather than bypassed.
Google Workspace
Sign-in, Drive, Sheets and Calendar as data sources and destinations for automated workflows.
REST API
Documented, versioned and authenticated endpoints — both consuming yours and exposing ours.
Custom Systems
In-house and legacy systems without a public API, reached through a documented adapter agreed with your team.

Expected effect

Described qualitatively. Actual impact depends on your volumes, data quality and process discipline.

Data stops being reconciled by hand between systems.
Failures become visible immediately instead of at month end.
Undocumented scripts are replaced by something maintainable.
Adding the next system becomes an incremental task rather than a new project.

Limits and what this does not do

It cannot resolve a genuine business disagreement about which system is authoritative. That must be settled by people before we build.
Vendor APIs impose rate limits and change without notice; adapters reduce that pain but do not remove it.
Systems with no interface at all may need a different approach entirely, and sometimes the honest answer is that integration is not viable.
