If you are shortlisting an API Development company in Pen, the useful question is not who has the longest feature list - it is who has worked with businesses like yours. Pen sits inside India, a business centre within India, and we build for that reality rather than a generic brief.
With 5+ years behind us and an in-house team covering design, development, QA and support, Gletus Technology builds REST and GraphQL APIs, documentation and versioning without handing your project through a chain of subcontractors.
For software projects that means clear data models, role-based access, audit trails and integrations that survive contact with your existing systems.
Whether you are launching something new in Pen or replacing a platform that has stopped earning its keep, the goal is the same: REST and GraphQL APIs, documentation and versioning that produce measurable commercial results.
API Development is also written as application programming interface development, and some people searching in Pen type API integration instead. They describe the same work - this page covers it under all of those names.
Our Portfolio

Why API Development here needs a different approach from a generic build.
Before scoping any API Development work in Pen, it is worth being specific about what this market actually runs on. Pen sits inside India's wider economy, where IT & Software, Retail & Trading, Manufacturing set the commercial pace and local firms compete for the same online attention.
Buyers here are relationship-led, price-sensitive and fast-moving, with decisions often made directly by the founder or promoter. Ignoring it produces a site that looks fine in a review meeting and converts poorly in the market.
The market is shaped by the fact that it is one of the fastest-growing digital economies in the world, with UPI payments, cheap mobile data and mobile-first buyers. Plenty of businesses in Pen still have no properly optimised presence on Google, which handles the overwhelming majority of searches in India, which leaves qualified demand unclaimed.
The commercial reasons that come up most often in conversations with clients here.
The problems clients most often bring us — and how we deal with each one.
Heavy builds waste ad spend and lose mobile users in Pen. Performance budgets are set at the start of the project, not audited after complaints.
Plenty of businesses in Pen have a site nobody can update because the original developer stopped answering. We hand over full access, credentials and documentation as a matter of course.
Payment, CRM and inventory links need error handling and retries. We test the failure paths, not just the happy path.
Contact forms and payment flows in Pen get probed constantly. Validation, rate limiting and backups are part of the baseline, not extras.
Locked-down builds force every small edit through a developer. We hand over a CMS your team can genuinely use.
If analytics and goals are not configured, nobody can tell what worked. We set up tracking before launch, not months later.
Where this market is heading, and what we build for because of it.
India is one of the fastest-growing digital economies in the world, with UPI payments, cheap mobile data and mobile-first buyers.
Business software in Pen is being rebuilt around APIs first, so the same data can feed a portal, a mobile app and a reporting dashboard.
AI answer engines now sit between the search box and the click, which rewards factual, well-structured pages and penalises padded content.
Privacy expectations keep tightening, and consent-aware analytics is becoming the default rather than a compliance exercise.
Our API Development work maps to the sectors that actually drive this market.

A representative engagement, anonymised at the client's request.
A Manufacturing client operating in Pen had outgrown spreadsheets, and reconciling data across teams was consuming several days of staff time every month.
We built a role-based platform consolidating their operational data, automated the reconciliation work that had been manual, and exposed an API so reporting could be generated on demand.
Results held after launch because tracking was in place from day one, so optimisation decisions were made on data rather than opinion.
The same sequence we follow on every API Development project in Pen, with a written checkpoint at each stage.
We map your goals, competitors in Pen and the questions your customers actually ask before buying.
User journeys, screen inventory and edge cases documented so nothing is discovered late.
Brand-aligned interface design with an accessible type, colour and spacing system.

Functional testing plus input validation, access control and backup verification.
Deployment, analytics verification, documentation and full credential handover.
Monthly reviews, A/B tests and prioritised improvements after launch.
The stack behind API Development projects we deliver in Pen — chosen for maintainability, not novelty.
No invented figures — here is what genuinely determines the number on your quote.
Pricing for API Development in Pen varies more with complexity than with location. Rather than publish a headline figure that would be wrong for most projects, here is what genuinely drives the number on your quote.
One thing we do not do is quote low and recover it through change requests. Scope is written down, and anything outside it is priced and approved before work starts on it.
We also scope in phases where budget is tight. A focused first release that earns revenue is almost always better than a complete build delayed by six months, and businesses in Pen rarely regret starting smaller.
What the DPDP Act and the sector rules change about the build.
A API Development project serving customers in Pen has to account for the Digital Personal Data Protection Act, 2023. We treat that as a design input rather than a disclaimer bolted on at the end, because retrofitting consent and retention into a finished system is far more expensive than building it in.
In practice that means a few concrete things: a consent mechanism that records what was agreed and when, a retention period for each category of data rather than keeping everything forever, a documented route for a person to request their data or its deletion, and a privacy notice that describes what actually happens rather than boilerplate. It also means RBI card-tokenisation rules, which mean you cannot store raw card numbers yourself.
On top of the general law come sector rules: PCI DSS the moment card data is involved, and materially tighter handling requirements for health, financial or children's data. We scope those in week one because they can change the architecture, not just the paperwork.
Accessibility applies to internal tools too, and it is where most fail. We build to WCAG 2.2 AA, which for admin software mostly means keyboard operability, honest form labelling and error messages that say what to do next.
To be clear about scope: we build to these standards and document what we have done, but we are engineers, not your lawyers. Anything with real regulatory exposure should be reviewed by someone qualified in India before you go live.
How we make sure the work we deliver actually surfaces in local search.
Whatever we build for you, it still has to be found by people in Pen who do not yet know your name. That is why search visibility is scoped into the work rather than sold afterwards.
The market is shaped by the fact that it is one of the fastest-growing digital economies in the world, with UPI payments, cheap mobile data and mobile-first buyers. We treat that as the starting position rather than a reason to avoid the market.
Practically, that means a complete and actively maintained Google Business Profile, consistent name, address and phone details wherever your business is listed, location-relevant pages that carry real information rather than a swapped city name, and structured data so search engines can read the page unambiguously.
Plenty of businesses in Pen still have no properly optimised presence on Google, which handles the overwhelming majority of searches in India, which leaves qualified demand unclaimed. Gaps like that close once one competitor takes them seriously, so timing matters more than budget here.
Honest ranges, and the three things that actually move them.
The question every buyer in Pen asks first is how long API Development takes, and the honest answer is a range rather than a date. For a first working module, plan on 8 to 12 weeks. For a full internal platform with roles and reporting, plan on 6 to 9 months. We commit to a date at the end of discovery, when it means something, rather than at the first call, when it cannot.
Schedules slip for predictable reasons: content that has not been written, approval chains nobody mapped, and an integration whose documentation turns out to be a phone number. We plan around all three rather than hoping.
Each milestone has a demonstrable output attached to it. If one moves, you hear about it in that fortnight rather than at handover.
Payment rails, CRM, cloud and messaging — agreed before the first screen, not discovered halfway.
API Development work in Pen is rarely a greenfield exercise. There is usually an existing payment arrangement, an accounting package and a pile of spreadsheets, and the build has to meet all three where they are.
On payments, the rails that matter in India are not the ones a generic template ships with. We work with UPI, Razorpay, PayU, Cashfree, CCAvenue, Paytm and PhonePe, and pick between them on settlement time, fee structure and how much of the compliance burden the provider absorbs. Whether UPI or Cashfree is right for you depends on your average order value and your refund pattern, not on which is better known.
Beyond payments, internal software in Pen lives or dies on integration: accounting (Tally, Zoho Books, QuickBooks or Xero depending on the market), identity through Google Workspace or Microsoft Entra, storage and compute on AWS or Azure, and messaging through Twilio or the WhatsApp Business API. We map every one of those before committing to a data model.
Every integration we add is documented with its credentials, its rate limits and its failure mode, and handed to you with the code. You are never in a position where only we know how the pieces connect.
Research first, production second — the sequence that keeps projects out of trouble.
We do not begin API Development work in Pen from a template library. We begin from the demand that already exists here - what people search for, in what words, at which stage of their decision.
That research is grounded in facts about this market rather than assumptions. Pen sits inside India's wider economy, where IT & Software, Retail & Trading, Manufacturing set the commercial pace and local firms compete for the same online attention. So the priorities we set for IT & Software and Retail & Trading clients here look nothing like the priorities we would set in a different market.
On the build side, that translates into concrete decisions: how roles and permissions are modelled, which processes get automated first, what the audit trail records, and how the system behaves when an integration is unavailable. We design the data model for where your business in Pen expects to be in three years, not just for today's process.
We work in visible increments: something reviewable lands regularly, so progress is observable rather than reported. It also means priorities can shift without renegotiating the whole engagement.
Pick the engagement model that fits how your business in Pen actually operates.
A smaller first release that earns revenue, then funded phases after it. Popular with businesses in Pen testing a new line.
Developers and designers working only on your roadmap, managed by us, reporting to you. For sustained multi-month programmes.
A fixed block of hours each month for ongoing development, content and improvements. Suits businesses that ship continuously.
Best when requirements are clear. Written scope, fixed price, milestone schedule. Change requests are quoted separately so the approved number holds.
What you actually get when you work with us, stated plainly.
Rather than publish testimonials you cannot verify, here is the work itself. Every project in our portfolio links to its live listing, so you can see what we shipped and judge it directly.

The questions we hear most from businesses searching for API Development in Pen.
API Development in Pen — answered directly.
Gletus Technology Pvt Ltd is an established API Development company serving Pen, with years of delivery experience and an in-house team covering strategy, design, development, QA and support. Rather than claiming a title, we would suggest judging any vendor in Pen on three things: relevant work you can actually inspect, a written scope, and whether you get direct access to the people building your project.
We start with an audit rather than a sales pitch - performance, structure, security, search visibility and conversion. Often the foundation is sound and targeted fixes cost a fraction of a rebuild. Where a rebuild genuinely is cheaper over two years, we will show you that arithmetic.
A conversation about goals, whatever brand assets exist, and one decision-maker who can approve at each milestone. Content can be developed alongside the build - missing content is the single most common cause of delay, so we plan for it from the start.
More questions we are asked about API Development in Pen:
Milestone-based delivery exists precisely so this is caught early. You review and approve at each stage, and if something is not right at a checkpoint we fix it before moving on. Disagreements about scope are settled against the written scope document rather than against memory.
Gletus Technology works across Pen and the wider Delhi NCR region. Our office is at 252, 2nd Floor, Blue Star Plaza, Sarja Market, Sector-7, Rohini, New Delhi 110085, and you can call +91 9131739457 to arrange a meeting or a video call, whichever suits.
Yes - our portfolio covers ecommerce platforms, marketplaces, brand websites and business applications, each with its own detail page and a live link you can open and evaluate yourself rather than a screenshot.
Usually within one to two weeks, depending on current commitments. We would rather give you an honest start date than book you in immediately and then run a project slowly, which is the more common outcome when a supplier promises to start the same day.
You do - completely. Source code, hosting, domain, analytics and any third-party accounts are transferred to your ownership at handover, with credentials and documentation. You are never locked into us to make changes.
Yes, and both are treated as requirements rather than as a later audit. We set a performance budget at kickoff and test on mid-range devices rather than only on flagship phones, because that is what most visitors in Pen actually browse on.
Yes - accounting, CRM, payment gateways, logistics and messaging platforms are all common. We check API availability during discovery, because an integration that looked simple in a sales meeting occasionally turns out to have no public API at all.
Role-based access control, encrypted credentials, audit logging, input validation and scheduled backups are part of the baseline build. For regulated sectors we scope the specific compliance requirements during discovery rather than assuming a generic standard.
That is the point of building custom. We design the data model and module boundaries for where you expect to be in three years, so adding users, locations or modules is configuration work rather than a rewrite.
Buyers here are relationship-led, price-sensitive and fast-moving, with decisions often made directly by the founder or promoter. That is not a guess we make at proposal stage - it comes from delivering work in this market and watching what converts.
India is one of the fastest-growing digital economies in the world, with UPI payments, cheap mobile data and mobile-first buyers. We factor that into the build rather than treating it as a future upgrade.
Demand tracks the local economy closely. Pen sits inside India's wider economy, where IT & Software, Retail & Trading, Manufacturing set the commercial pace and local firms compete for the same online attention. Those are the sectors we field the most enquiries from here.
A first working module is typically 8 to 12 weeks; a full internal platform with roles and reporting runs 6 to 9 months. What moves those dates is rarely the engineering - it is how quickly content arrives, how many people must approve a decision, and whether a third-party system turns out to be documented. We commit to a date at the end of discovery, when it means something, rather than on the first call.
We build to WCAG 2.2 AA: semantic headings, form controls with real labels, keyboard-operable navigation, a visible focus state, sufficient colour contrast, and no meaning carried by colour alone. It widens the audience you can sell to in Pen, it is increasingly what procurement asks about, and it overlaps almost entirely with what search engines reward anyway.
For clients in India we work with UPI, Razorpay, PayU, Cashfree, CCAvenue, Paytm and PhonePe. The right choice depends on your average order value, refund pattern and settlement timing rather than brand familiarity - at low volume UPI is usually the practical default, and we will say plainly when a cheaper provider would cost you more in reconciliation time. Card details always go straight to the gateway, so your system stores a token rather than a card number.
You do, entirely - source code, database, design files, and every account we register on your behalf. Gateway, analytics and hosting accounts go in your name with you as owner and us added as a user, so if you stop working with us nothing needs re-registering and no service is interrupted. There is no fee to leave and no licence retained.
Yes - accounting (Tally, Zoho Books, QuickBooks or Xero), identity through Google Workspace or Microsoft Entra, storage and compute on AWS or Azure, and messaging through Twilio or the WhatsApp Business API. Every connection is documented with its credentials, rate limits and failure behaviour, and the accounts are registered in your name so nothing goes dark if you change supplier.
Pen में सॉफ़्टवेयर से जुड़े वे सवाल, जो ग्राहक काम शुरू करने से पहले सबसे ज़्यादा पूछते हैं।
हाँ। Gletus Technology Pvt Ltd का ऑफ़िस रोहिणी, नई दिल्ली में है और हम Pen के क्लाइंट्स के साथ काम करते हैं। ज़्यादातर काम ऑनलाइन मीटिंग और साझा ट्रैकर पर होता है; ज़रूरत पड़ने पर आमने-सामने बैठक भी की जा सकती है।
हाँ। वेबसाइट हिंदी सहित अन्य भारतीय भाषाओं में या दो भाषाओं में एक साथ बनाई जा सकती है, और हर भाषा के लिए अलग URL रखा जाता है ताकि Google उसे सही भाषा में दिखा सके।
लागत पूरी तरह स्कोप पर निर्भर करती है - कितने पेज या स्क्रीन चाहिए, कौन-से फ़ीचर चाहिए, और किन बाहरी सिस्टम से जोड़ना है। हम काम शुरू करने से पहले लिखित कोटेशन देते हैं जिसमें स्कोप, टाइमलाइन और भुगतान के चरण साफ़ लिखे होते हैं, ताकि बाद में कोई छिपा हुआ चार्ज न आए। इसी पेज पर ऊपर लागत वाला सेक्शन देखें।
हाँ। कई बार पूरी वेबसाइट दोबारा बनाने की ज़रूरत नहीं होती - डिज़ाइन, स्पीड और मोबाइल व्यू सुधारकर ही अच्छा नतीजा मिल जाता है। हम पहले मौजूदा साइट देखकर बताते हैं कि रीडिज़ाइन ठीक रहेगा या नए सिरे से बनाना।
समय फ़ीचर्स और कंटेंट की तैयारी पर निर्भर करता है। सबसे बड़ी देरी आमतौर पर डेवलपमेंट से नहीं, बल्कि कंटेंट, इमेज और अप्रूवल के इंतज़ार से होती है - इसलिए हम शुरू में ही यह तय कर लेते हैं कि क्या-क्या आपकी तरफ़ से चाहिए। इसी पेज पर टाइमलाइन वाला सेक्शन चरणवार ब्योरा देता है।
हाँ। लॉन्च के बाद तय अवधि तक सुधार और सहायता शामिल रहती है, और उसके आगे मेंटेनेंस अलग से लिया जा सकता है। कोड, डोमेन और होस्टिंग का एक्सेस आपका रहता है - किसी भी स्थिति में आप हम पर निर्भर नहीं रहते।
बनाते समय ही तकनीकी SEO का आधार तैयार किया जाता है - साफ़ URL, टाइटल और डिस्क्रिप्शन, स्ट्रक्चर्ड डेटा, तेज़ लोडिंग और मोबाइल पर सही रेंडरिंग। इसके आगे लगातार कंटेंट और लोकल SEO का काम अलग सेवा के रूप में लिया जा सकता है।
हाँ। भारत में ज़्यादातर ग्राहक फ़ॉर्म भरने के बजाय WhatsApp पर बात करना पसंद करते हैं, इसलिए हम WhatsApp बटन और क्लिक-टु-कॉल जोड़ते हैं, और चाहें तो फ़ॉर्म की जानकारी सीधे आपके WhatsApp या ईमेल पर भेजी जा सकती है।
