API integration
Making systems that were never meant to talk, talk.
Integration is where most projects quietly fail. Getting the happy path working is the easy half; the half that decides whether your system is still standing next year is everything around it, the marketplace that changes its API without warning, the webhook that fires twice, the request that dies mid-flight. We build for those cases rather than for the demo.
Signs you are describing this problem badly and us well.
Any one of these is fixable. All four at once usually means the problem is structural, which is a better conversation to have early.
- Orders arrive by phone, WhatsApp or email and someone re-types them into a system.
- Stock levels disagree between the storefront and the back office.
- A provider change broke something and nobody knows for how long.
- You cannot answer a customer asking where their order is, only guess.
What api integration actually involves.
REST and webhook API design
A contract that survives the next provider change. Versioned, documented, and shaped so your clients can be added without a redeploy.
Marketplace and payment integration
WooCommerce, Shopify, and the local payment rails. Order sync that reconciles rather than duplicates, because a double-fulfilled order is worse than a delayed one.
Legacy and internal system integration
The spreadsheet or on-prem system everyone depends on and nobody wants to replace. We wrap it rather than asking you to migrate it first.
Reliability: retries, idempotency, observability
Queue-backed retries and deduplication keys on anything that charges money or moves a parcel, plus the logging that lets you prove what happened when a customer disputes it.
Proof
Shipped, not described.
GoFlow, two independent commerce platforms reconciled into one dispatch queue through a live REST and webhook layer.

Do you work with APIs we already use?
Yes, that is most of the work. WooCommerce, Shopify, the Nigerian payment gateways, ERPs and whatever your operations team currently maintains by hand. If it has an API we integrate with it, and if it does not we wrap it rather than making you replace it first.
What happens when a provider changes their API?
That is what the integration layer is for. Everything the provider does is isolated behind our own contract, so a provider change is an adapter to update rather than an outage. GoFlow runs live commerce integrations specifically to prove this is not a theory.
Is integration a one-off cost or ongoing?
Building it is one-off. Keeping it standing is where most of the value is, and we operate what we ship until your team is ready to take it. We would rather hand over a documented contract than a dependency on us.
