API development & integrations — webhooks, middleware & contracts
Clean boundaries between systems: explicit schemas, auth patterns, and failure behavior your on-call can reason about.
API and integration services for SaaS and internal tools
Integration searches often mean ‘make two SaaS tools talk.’ We treat integrations like product work: contracts, versioning, observability, and rollbacks. SEO copy names concrete providers because due diligence teams literally search them while checking vendor fit.

What buyers get on this engagement
Fewer midnight pages
Alerts tied to business metrics, not generic 500 spam.
Vendor reality
Rate limits and flaky sandboxes planned for.
Future you
Versioned endpoints so mobile and partners are not broken silently.
Security
Secret rotation and least-privilege service accounts.
Phases from brief to handoff
Like our practice hubs and technology stack pages, we keep scope readable: written milestones, demo checkpoints, and assumed budgets before long commits — so procurement and founders stay aligned.
Integration discovery
Systems, objects, directionality, SLAs.
Spike
Prove auth + happy path in sandbox.
Build + tests
Handlers, retries, monitoring, docs.
Cutover support
Shadow mode, parallel runs, rollback plan.
Typical bands before your final quote
| Phase / package | What is included | Typical timeline | Assumed from |
|---|---|---|---|
| Integration plan | Sequence diagram-level map + quote | 3–7 days | ~$2k–$6k |
| Single high-value bridge | Bi-directional or event-driven sync with monitoring | 2–6 wks | ~$10k–$35k |
| Platform program | Many partners, admin UI, webhook portal, SLAs | 6–16+ wks | ~$35k–$120k+ |
Assumed bands are typical before unusual integrations, heavy compliance, or bespoke UI — we confirm fees in writing after a short brief. Most engagements are milestone-invoiced in USD.
Often paired services
Integration artifacts
Docs are part of reliability — not a PDF afterthought.
- OpenAPI / schema repo
- Postman or curl collections
- Runbook for credential rotation
- Monitoring dashboards or log queries
- Load/throughput notes
- Cutover checklist
