Web Development Service #13 / 58
Your customers are already on WhatsApp. Your business systems are not. We connect them — so order confirmations, delivery alerts, appointment reminders, support replies, and payment links go out on WhatsApp automatically, triggered by events in your software, with no manual sending required.
Marketing Wise has delivered 50+ WhatsApp Business API integrations for eCommerce brands, logistics companies, healthcare providers, and service businesses across Noida and Delhi NCR. We handle the full setup: Meta Business verification, WABA provisioning, template approval, and integration with your existing stack — so you are sending real messages within weeks, not months.
We build beyond simple notification pipes. Complex integrations include two-way chat routing to your support team with a shared inbox, AI-powered chatbots that resolve common queries before escalating, abandoned cart recovery sequences, payment link delivery with Razorpay, and broadcast campaign management with opted-in lists and delivery analytics.

No mystery phases. Four gates every WhatsApp API integration crosses — from Meta verification to live messaging.
We set up your Meta Business Manager, submit business verification documents, register your dedicated phone number, and configure your WhatsApp Business Account. Message templates for all use cases are drafted and submitted for Meta approval in parallel.
API integration with your platform (eCommerce, CRM, ERP, or custom system) is built and tested in sandbox mode. Approved message templates are loaded. Trigger logic — the events that fire each message — is defined and implemented.
Chatbot conversation flows are built, tested, and tuned on real query samples. Shared inbox setup, agent assignment rules, and CRM context injection are configured. Human escalation paths are tested for all chatbot failure scenarios.
End-to-end testing across all message triggers, opt-in flows, and reply handling is completed. Message frequency limits and unsubscribe handling are verified against Meta policy. Delivery analytics are wired up and the integration goes live with monitoring.
Customer support inbound queries reduced by 52%. WhatsApp notification open rate 94% vs 18% for email equivalents.
The brand sent order updates by email — open rates were poor, customers kept calling for status. The support team spent 4 hours daily answering "where is my order?" from customers who had not seen the email.
We integrated the WhatsApp Business API with Shopify and Shiprocket to send automated messages at each order event: confirmed, packed, dispatched (with tracking link), out for delivery, delivered, and return initiated. All message templates were pre-approved before go-live.

Appointment no-show rate reduced from 31% to 9%. Prescription delivery via WhatsApp replaced printed handouts for 78% of patients within 60 days.
The clinic chain had 400+ appointments daily across 3 locations. No-shows were high because reminders were done manually by phone — time-consuming and inconsistent. Prescriptions were paper-only.
We built a WhatsApp integration with their HMS (hospital management system) — automated appointment reminders 24 hours and 2 hours before the slot, a confirm/cancel reply flow, and digital prescription delivery as a PDF immediately after the consultation.

Average query response time reduced from 4.2 hours to 18 minutes. Agent productivity increased — each agent handled 3× more conversations per day.
The company's operations team managed client queries across 4 WhatsApp numbers on personal phones — no visibility across the team, queries were missed, and there was no record of what had been communicated.
We built a shared WhatsApp inbox integrated with their TMS — all 4 numbers consolidated, conversations assigned to agents, shipment status fetched automatically from TMS context, and a full conversation history per client.

"They delivered our platform in 12 weeks, on budget and exactly to spec. Weekly demos kept us informed at every stage and the final product matched the requirements document line by line."
"The API architecture they designed handles our peak load without breaking a sweat. We have had zero downtime in eight months of production. The codebase is clean, documented, and our internal team can extend it independently."
"We evaluated three development agencies before choosing Marketing Wise. Their scoping process was the most rigorous — they produced a requirements document that found two gaps we had not identified ourselves."
"The backend they built scaled from 500 to 15,000 daily active users in six months without a single architecture change. That kind of headroom built into the design is rare from an agency engagement."
"Post-launch support was exceptional. They flagged and fixed two edge cases we had not anticipated within 24 hours. The handover package — source code, infra docs, runbook — meant our team could take ownership immediately."

Delivery follows a documented, repeatable methodology: (1) Discovery and requirements mapping — business logic, data model, integration landscape.

(4) Component-level UI engineering — React or Next.js, WCAG compliant, Core Web Vitals optimised. (5) Automated QA — unit, integration and end-to-end test suites. (6) Staged cloud deployment — dev, staging, production environments with CI/CD.

Mutual NDA signed before any discovery call — business logic, workflows, data structures and competitive information are kept confidential throughout and after engagement. Fixed-price contracts for clearly scoped work — line-item quote broken down by module, not a lump sum. Monthly retainers for ongoing product development.
