MTD Technologies handles custom coding work when off-the-shelf tools are not enough. This includes APIs, integrations, dashboards, backend logic, custom WordPress features, and automation scripts that support specific business needs.
MTD Technologies delivers custom api development services and custom coding when off-the-shelf tools are not enough: APIs, integrations, dashboards, backend logic, custom WordPress features and automation scripts built around specific business needs. It suits businesses whose workflows no packaged product quite fits, and who need software shaped to their process instead.
Purpose-built software features
Custom development is useful when a business process needs precise logic, a cleaner admin workflow, or an integration between tools that do not naturally talk to each other. The work is scoped around the outcome first, then built with the right stack.
- PHP, Laravel, FastAPI, and Python development
- REST API and third-party integrations
- Custom WordPress hooks and plugins
- React, Next.js, and Vue.js interfaces
Fixes, extensions, and automation
Not every project needs a full rebuild. MTD Technologies can repair broken features, extend existing systems, improve performance, automate repetitive tasks, and create dashboards around current data sources.
- Bug fixing and refactoring
- Workflow automation
- Admin dashboards and reporting
- Secure data handling and validation

Done-for-you API integrations
Your business runs on a dozen disconnected tools: the CRM does not talk to the accounting software, orders live in one place and inventory in another, and your team retypes data between them. We connect those systems with clean, documented integrations — so information flows automatically and the double-entry stops.
- CRM and sales tools: HubSpot, Zoho, Salesforce, Pipedrive — two-way sync of contacts, deals, and activities.
- Payments and billing: Stripe, PayPal, and local gateways wired into your checkout, invoicing, and reconciliation.
- Marketing automation: email platforms, SMS, and ad platforms fed from real business events.
- Custom APIs: when you need your own API for partners or mobile apps, we design and document it properly.
Frequently asked questions
Which systems can you connect?
Any system with an API — which is nearly all modern business software. The most common integrations we build are CRMs (HubSpot, Zoho, Salesforce), payment processors (Stripe, PayPal), accounting tools, email/SMS platforms, and custom ERPs. If a system has no API, we can usually still integrate via scheduled imports, n8n workflows, or controlled scraping.
How much does an API integration cost?
A straightforward two-system sync (for example, WooCommerce orders into a CRM) typically runs $1,000–$3,000. Multi-system workflows with custom logic usually range from $3,000 to $10,000. n8n-based automations for standard tools often come in lower.
How long does an integration take?
Simple integrations are live in 1–3 weeks. Complex multi-system projects take 4–8 weeks including testing. We always map the data flow with you first, because most integration failures come from unclear requirements, not from code.
What if one of our tools has no API?
There is almost always a path: scheduled CSV/SFTP imports, email parsing, robotic-style browser automation, or a middleware layer in n8n. We will assess the specific tool and recommend the most reliable option rather than forcing a fragile hack.
Do we get documentation?
Yes. Every integration ships with documentation covering what syncs, how often, how errors are handled, and what to do when something changes upstream. Your team is never locked into mystery code.
Need systems connected, not custom code? Our API integration services for small business handle done-for-you CRM, ERP, and payment integrations.
Exactly what you get in a custom API build
We build the API your product needs — not a generic CRUD generator. Every build includes:
- API design first: resource modeling, versioning strategy, and error conventions — agreed in writing before coding.
- Custom endpoints: business logic your off-the-shelf tools can’t express, built to spec.
- Authentication & authorization: JWT, OAuth2, API keys — matched to your consumers and threat model.
- Validation & error handling: strict input validation with clear, actionable error responses.
- Rate limiting & quotas: fair-use protection built in from day one.
- Documentation: OpenAPI/Swagger docs your consumers can actually build against — plus guides, not just references.
- Testing: automated test suites covering happy paths, edge cases, and auth — wired into CI.
- Deployment: containerized, monitored, with zero-downtime deploys.
Need systems connected rather than built? That’s our API integration service — same team, different engagement.
Custom API development pricing
Fixed quotes after a free scoping call. As a guide: a focused API (auth, a dozen endpoints, docs) typically runs $3,000–$7,000. Platform-grade APIs with complex logic, webhooks, and multiple consumer types run $8,000–$25,000+.
When custom beats off-the-shelf
- Mobile app backends: purpose-built endpoints shaped for your app’s exact screens and flows.
- Partner/developer APIs: a public API as a product — with docs, keys, and SLAs.
- Legacy modernization: a clean API layer over the old system, so new products don’t inherit old constraints.
- Workflow glue: custom endpoints that automation platforms and AI agents call as tools.
Our API engineering standards
- Versioned from day one: v1 in the URL path, so v2 never breaks existing consumers.
- Predictable errors: consistent error shapes with codes your consumers can handle programmatically.
- Idempotency where it matters: payment and order endpoints safe to retry.
- Observability: structured logging, metrics, and tracing — when something’s slow, we know which endpoint and why.
Why MTD for custom APIs
- API-first for 9+ years: 300+ projects of designing interfaces other developers depend on.
- Framework-agnostic: FastAPI for Python speed, Laravel for PHP ecosystems, Node where it fits — matched to your stack, not our preference.
- Consumer empathy: we’ve been on the consuming side of bad APIs; we build the ones we wish vendors gave us.
More questions, answered
How much does custom API development cost?
A focused API typically costs $3,000–$7,000 fixed. Platform-grade APIs with complex logic run $8,000–$25,000+. Fixed quotes after a free scoping call.
How long does it take to build a custom API?
Focused APIs ship in 3–6 weeks. Platform-grade APIs take 8–16 weeks. The design phase (usually week one) is what prevents expensive rework later.
REST vs GraphQL — which should we choose?
REST for most cases — simpler caching, tooling, and consumer onboarding. GraphQL when consumers need flexible queries across related resources (dashboards, mobile apps with varied screens). We’ll recommend based on your consumers, not trends.
Do you document the API?
Yes — OpenAPI documentation generated from the code (so it can’t drift), plus integration guides with real examples. Undocumented APIs are unfinished work in our book.
Can you build an API for our mobile app?
That’s a core use case. We design endpoints around your app’s screens and flows — including offline-sync patterns and push notification hooks where needed.
How do you handle API security?
Authentication matched to consumers (JWT/OAuth2/API keys), authorization checks on every endpoint, input validation, rate limiting, and security review before launch. Security isn’t a phase — it’s in every layer.
The frameworks behind our custom coding
Custom coding is only as good as the stack it stands on. Our framework bench covers the three ecosystems most business software is built in today: PHP with Laravel — Livewire interfaces and Filament admin panels, covered in depth on our Laravel development services page; TypeScript with Next.js and React for front-ends and full-stack web apps — see our Next.js development services; and Python with FastAPI and Django for APIs, data services, and automation — see our Python development services and FastAPI development pages. Whatever the language, the deliverable is the same: documented, tested code your business owns outright.
