Systems that exchange data on purpose
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.
Sales, warehouse, and finance disagree because each system was updated by hand. Integration is how a business gets one timeline of events.
Rate limits, pagination, auth expiry, and webhook signatures are where projects stall. We read the vendor’s real constraints before writing glue code.
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.
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.
Versioned REST APIs with authentication, pagination, and error shapes that clients can program against.
Payments, shipping, tracking, CRMs, ERPs, and marketplace APIs, including sandbox-to-production cutover.
Inbound verification, outbound retries, and mapping of vendor events onto your domain objects.
OpenAPI, examples, and a checklist your future self will thank you for when the original developer is on leave.
We list sources of truth, who is allowed to write, and which events must never be lost (payments, stock decrements, refunds).
Payloads, idempotency keys, and failure semantics are written down. Code follows the contract, not the other way around.
Vendor sandboxes, recorded payloads, and replayable jobs. We do not discover pagination limits in production.
Dashboards for lag, error rates, and poisoned messages. A runbook for the 2am vendor outage.
Orders flow in, stock flows back, and partial failures are visible instead of becoming oversells.
Listings, orders, and inventory updates with respect for each marketplace’s rate limits and status models.
A charge is not the same event as a shipment. We keep those state machines honest.
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.
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.
Secrets stay in environment configuration or a secret manager, not in git. Rotations and least-privilege scopes are part of the design.
Vendors change APIs. We can include a support retainer or document what your team must watch. An integration without an owner will eventually break.

Share the current system, the constraint, and the outcome you need in the next quarter. We will say if Palmate is a fit.
