Systems that exchange data on purpose
API Development and Integration
Palmate Solutions designs and implements APIs and integrations for businesses that need their tools to share a single operational picture. That includes first-party REST APIs, payment and tracking providers, e-commerce platforms, ERPs, inventory systems, and marketplace connections. We care about contracts, retries, idempotency, and what happens when a vendor is down — not just a happy-path demo.
Problems this work solves
Every team has a different number
Sales, warehouse, and finance disagree because each system was updated by hand. Integration is how a business gets one timeline of events.
The vendor API was treated as documentation optional
Rate limits, pagination, auth expiry, and webhook signatures are where projects stall. We read the vendor’s real constraints before writing glue code.
Failures are silent
A nightly sync that ‘usually works’ is an operational hazard. We add observability, dead-letter handling, and a way for a human to replay an event.
Point-to-point spaghetti
When every app talks to every other app, change becomes dangerous. We introduce a clear owner for each flow — often a small integration service — so mappings live in one place.
Who it is for
- E-commerce and wholesale teams reconciling stock across stores and marketplaces
- Finance and operations teams connecting payments, invoicing, and fulfilment
- Product teams that need a stable public or partner API
- Companies replacing brittle Zapier-style zaps with something they can test and monitor
What Palmate can provide
API design and implementation
Versioned REST APIs with authentication, pagination, and error shapes that clients can program against.
Third-party integration
Payments, shipping, tracking, CRMs, ERPs, and marketplace APIs, including sandbox-to-production cutover.
Webhooks and event sync
Inbound verification, outbound retries, and mapping of vendor events onto your domain objects.
Partner and internal API documentation
OpenAPI, examples, and a checklist your future self will thank you for when the original developer is on leave.
Typical workflow
- 01
Inventory the systems and events
We list sources of truth, who is allowed to write, and which events must never be lost (payments, stock decrements, refunds).
- 02
Contract first
Payloads, idempotency keys, and failure semantics are written down. Code follows the contract, not the other way around.
- 03
Build with fixtures
Vendor sandboxes, recorded payloads, and replayable jobs. We do not discover pagination limits in production.
- 04
Operate the integration
Dashboards for lag, error rates, and poisoned messages. A runbook for the 2am vendor outage.
Common use cases
WooCommerce or custom store to ERP / inventory
Orders flow in, stock flows back, and partial failures are visible instead of becoming oversells.
Marketplace and Amazon-style channels
Listings, orders, and inventory updates with respect for each marketplace’s rate limits and status models.
Payment plus fulfilment orchestration
A charge is not the same event as a shipment. We keep those state machines honest.
FAQ
Can you integrate a system without an official API?
Sometimes, via exports, official middleware, or a vendor-supported integration layer. Scraping HTML or using unofficial endpoints is a last resort and a maintenance risk we will not hide.
Do you build real-time sync?
When the business needs it and the vendors support it. Many ‘real-time’ requests are better served by near-real-time queues with a lag SLO you can actually meet.
How do you handle credentials?
Secrets stay in environment configuration or a secret manager, not in git. Rotations and least-privilege scopes are part of the design.
Will you maintain the integration after launch?
Vendors change APIs. We can include a support retainer or document what your team must watch. An integration without an owner will eventually break.
