API integrations and workflow automation for businesses in the Dominican Republic — connect PayPal, Stripe, WhatsApp Business, and CRMs via Resend. Starting from $500.
Most businesses in the Dominican Republic use multiple digital tools that don't talk to each other — a booking system that doesn't sync with their CRM, a website contact form whose leads never reach their email automatically, a payment processor that requires manual reconciliation every day. API integrations eliminate all of that by creating direct connections between your platforms so data flows automatically, forms trigger follow-ups, and payments update records without anyone touching a spreadsheet.
We build API integrations for Dominican Republic businesses using the same tools that power our full web application builds — Resend for transactional and automated email — with React Email templates, real-time delivery webhooks, and built-in DKIM/SPF/DMARC for inbox deliverability, PayPal and Stripe APIs for payment processing, WhatsApp Business API for customer notifications, and REST API connections to CRMs like HubSpot, email platforms like Mailchimp, scheduling tools, Google Workspace, and any third-party service with an available API. Our Sertuin Events project is a real example: we integrated Resend to automate proposal generation and client communication emails — eliminating hours of manual follow-up work for the client every week.
Whether you need a single integration (adding WhatsApp notifications to your booking form) or a full automation architecture connecting multiple platforms, we scope the work precisely and build only what your business actually needs. Starting from $500, API integrations are the highest-ROI investment for businesses whose team is spending significant time on tasks that could be automated.
We build API integrations as part of every web application we deliver — from Resend email automation in Sertuin Events to PayPal and Stripe payment APIs in our e-commerce builds. We know how these systems connect because we've built them in production.
Every automated workflow eliminates a manual task — data entry, copy-pasting between tools, sending follow-up emails — freeing your team for work that actually requires a human.
Automated data sync eliminates the typos, missed entries, and outdated records that come with manual processes — your systems always have accurate, current data.
An integration built correctly handles 10 orders or 10,000 orders the same way — no additional staff required as your business volume grows.
PayPal, Stripe, WhatsApp Business, HubSpot, Mailchimp, Google Workspace, Calendly, Twilio — if it has an API, we can connect it to your site or application.
Webhook-based triggers fire instantly — a new booking updates your CRM, triggers a confirmation email, and sends a WhatsApp notification all within seconds of the event.
We don't over-engineer. We map your current manual processes, identify what's worth automating, and build only what delivers real ROI — no unnecessary complexity.
Every API integration we build is production-ready, documented, and tested end-to-end before going live.
Secure connection to external services using REST APIs, OAuth authentication, and API key management — built to your platform's specific requirements and rate limits.
Real-time event triggers — when something happens in one system (a new order, a form submission, a payment), an action fires automatically in another system without polling or delays.
Contact form submissions, bookings, and purchases automatically create or update records in HubSpot, Salesforce, or your CRM of choice — zero manual entry.
Transactional and triggered emails via Resend — using React Email templates for beautiful, reliable emails with built-in DKIM/SPF/DMARC authentication and real-time delivery webhooks — confirmations, follow-ups, alerts, and notifications sent automatically based on user actions.
Every integration is documented — what it connects, how it triggers, what data flows where, and how to monitor it — so your team understands and can manage it after handover.
Send automatic WhatsApp notifications to customers on bookings, orders, or any trigger event — essential for Dominican Republic businesses where WhatsApp is the primary customer communication channel.
Build a custom bridge for platforms without standard API documentation — proprietary systems, legacy software, or niche tools that require a bespoke connection layer.
Connect three or more platforms in a single automation architecture — for example, website form → CRM → email campaign → WhatsApp notification — all triggered by a single event.
Our proven process ensures your project is delivered on time, on budget, and exceeds expectations.
We map your current manual workflows, identify which tools need to connect, define the data that needs to flow between them, and document the exact trigger conditions and expected outputs — before writing a single line of integration code.
We design the integration architecture — selecting the right approach (REST API, webhook, polling, or custom connector), mapping all endpoints, and planning error handling and fallback logic before development begins.
We build the integration logic — API connections, webhook handlers, data transformation, authentication flows, and automated triggers — with error logging and retry logic built in from the start.
Every trigger, data transformation, and automation flow is tested end-to-end — including failure scenarios, duplicate event handling, and rate limit behavior — before any live deployment.
We deploy the integration to production, verify it's running correctly under real conditions, set up error alerting, and hand over full documentation — so your team knows exactly how to monitor and manage it going forward.
