API Integration Services

Reliable APIs, webhooks, and data flow.

I connect apps, CRMs, payment systems, dashboards, WordPress, WooCommerce, and mobile backends with clean API contracts and failure-aware workflows.

Core delivery

The practical work this service usually includes.

  • REST API design and integration
  • JWT auth and protected endpoints
  • Webhook handlers and retries
  • Data mapping and transformation
  • Third-party API troubleshooting
  • Admin logs and monitoring

Who this is for

Built for teams whose systems need to talk to each other.

API integration work usually comes from one of these situations.

C

Teams replacing manual data entry

Someone is currently copying data between two systems by hand — a CRM, a spreadsheet, an e-commerce platform — and it needs to sync automatically instead.

V

Products needing a third-party API

Your app needs to talk to a payment processor, mapping service, messaging platform, or industry-specific API, and the integration needs to handle failures gracefully.

P

Platforms exposing their own API

You need to expose clean, documented, authenticated endpoints for partners, mobile apps, or internal tools to consume.

Common problems solved

The integration requests I actually get.

"The integration works until the third-party API fails"

Retry logic, timeouts, and fallback handling built in from the start, so a slow or failing external API degrades gracefully instead of breaking your whole workflow.

"We're not sure our webhook data is even trustworthy"

Signature verification, idempotency handling, and proper logging added so webhook events are authenticated and never processed twice.

"Two systems use completely different data formats"

Data mapping and transformation layers built between systems with mismatched schemas, so both sides keep working without either one changing.

"We don't know when an integration silently breaks"

Logging, alerting, and an admin view added so failures surface immediately instead of being discovered a week later from a customer complaint.

Frequently asked

Questions before you reach out.

Which platforms and APIs have you integrated with?

WordPress, WooCommerce, CRMs, payment gateways, and general REST/JSON APIs are common — if a service has a documented API, it can very likely be integrated.

Do you write API documentation too?

Yes — when you're exposing your own API to partners or other teams, clear documentation is part of a proper delivery, not an afterthought.

Can you fix an integration someone else built badly?

Yes. Broken or fragile integrations are a common request — diagnosed first, then either patched or rebuilt depending on what's more cost-effective.

How do you handle authentication?

JWT, OAuth, API keys, or whatever the target system requires — implemented with proper token handling and refresh logic, not hardcoded credentials.

What do you need from me to start?

Access or documentation for the systems being connected, and a description of what data needs to flow where and how often.

Do you monitor integrations after launch?

Launch support is included, and monitoring/alerting can be built in so failures are caught early — ongoing support retainers are also available.
