Custom Software Development
Stop re-keying data between systems. We design REST, webhook, and batch integrations—with retry logic, mapping layers, and observability—so your custom software and third-party tools share a single source of truth where you need it.
API integration services cover discovery of vendor documentation, authentication models, rate limits, idempotency, and failure recovery. We implement connectors as part of new custom apps or as upgrades to software already in production—always documenting which system owns master data for each entity.
List applications, APIs, exports, and manual steps today.
Field-level mapping, transformations, and conflict rules.
OAuth, API keys, or mutual TLS stored securely.
Exercise vendor sandboxes before production cutover.
Alerts on failed jobs, queue depth, and stale sync.
Runbooks for support teams and versioning policy.
Checkout sessions, refunds, and webhook reconciliation into billing modules.
SMS, WhatsApp Business APIs, or email providers for notifications.
Push invoices or payments where official APIs or exports exist.
Lead sync, campaign triggers—scoped to documented endpoints.
Connect modules built in separate phases into one experience.
Scheduled CSV/XML imports when modern APIs are unavailable.
Integrations often accompany inventory, billing, CRM, or SaaS products. We do not claim partnerships with every vendor—feasibility is verified per API.
We assess documentation quality, sandbox access, and legal terms before committing—some legacy systems only support file exchange.
Webhooks and polling for near-real-time; nightly batches when volumes or vendor limits require it.
Secrets live in environment vaults or managed stores—not source control—with rotation procedures documented.
Possible when both sides expose write APIs; conflict resolution rules must be agreed upfront.
Yes—we can publish documented REST/GraphQL APIs for your product customers.
Operational SLAs are defined in support agreements; third-party outages remain outside our control but we surface status clearly.
Contract tests against sandboxes, replay fixtures, and staged rollout with rollback plans.
