API Development & System Integration

Service Overview

Modern software products don't operate in isolation — they sit at the centre of an interconnected ecosystem of CRMs, payment processors, analytics platforms, data providers, and partner APIs. Techglock designs and builds API layers that are not just functional but truly production-grade: secure by design, documented comprehensively, versioned thoughtfully, and monitored proactively.

API-First Design: We follow API-first principles — defining the contract before implementation using OpenAPI / Swagger specifications. This approach enables frontend and backend development to proceed in parallel, ensures clear communication between teams, and produces APIs that third-party developers can consume confidently. Every endpoint is secured with OAuth 2.0 or JWT, rate-limited, and tested with Postman/Newman in CI pipelines.

Integration Complexity, Solved: Whether you need to integrate a single payment gateway or orchestrate data flows across a dozen enterprise systems, our team has the depth to handle complexity gracefully. We have integrated with Salesforce, SAP, Oracle, Stripe, Twilio, SendGrid, HubSpot, and hundreds of other platforms — and we know how to handle the quirks, rate limits, and failure modes that real-world integrations encounter.

Frequently Asked Questions

The questions clients ask most often before kicking off a api development & system integration engagement.

How long does a api development & system integration engagement take?

Most api development & system integration projects ship within 8–14 weeks. Typical timeline: 1 week for discovery and scoping, 1–2 weeks for solution design, 4–8 weeks of agile delivery sprints, and 1–2 weeks for QA, security review, and go-live. We give you a fixed timeline before any work starts — no surprises three months in.

How much does api development & system integration cost with Techglock?

Pricing depends on scope, but most api development & system integration engagements land between $15,000 and $80,000 depending on complexity, integrations, and team size. We offer both fixed-price and time-and-materials models. Every quote breaks down per-deliverable so you can scale up or scale back before committing.

Do you sign NDAs before discussing the project?

Yes — request a mutual NDA when you book the discovery call and we send it within the hour. We have signed thousands of NDAs across regulated industries (healthcare, finance, defence) and never had a confidentiality dispute.

What does your api development & system integration team look like?

Every engagement gets a dedicated squad: a senior tech lead, 2–4 engineers, a project manager, and (where relevant) a designer or DevOps engineer. No offshore handoffs, no junior-only teams, no rotating staff. The people you meet on day one are the people who ship the project.

What happens after the API Development & System Integration project launches?

Every engagement includes 30 days of free hypercare (bug fixes, performance tuning, user-feedback iteration). Beyond that, we offer monthly retainers from $1,500/month covering monitoring, security patches, dependency updates, and a fixed pool of iteration hours. Roughly 80% of clients move onto a retainer after launch.

Who owns the code and IP we build together?

You do — completely. Once final invoice is settled, all source code, designs, infrastructure-as-code, and CI/CD pipelines transfer to your accounts. No vendor lock-in, no licensing fees on code we wrote, no hidden escrow.
