Connect your ERP, CRM, and business applications with custom API integrations built for reliability, security, and scale. We design integration architectures that eliminate data silos and automate the workflows slowing your team down.
Your business runs on multiple platforms — an ERP for operations, a CRM for sales, payment processors for revenue, and marketing tools for growth. When these systems don't talk to each other, your team fills the gap with manual data entry, spreadsheet exports, and copy-paste routines that waste hours every week.
API integration services connect those disconnected platforms so data flows automatically between them. Orders entered in your eCommerce platform update inventory in your ERP. Leads captured by your marketing tools appear instantly in your CRM. Payment confirmations trigger invoicing without anyone lifting a finger.
The result: fewer errors, faster decisions, and a team that spends its time on work that actually moves the business forward.
As your business grows, so do your integration needs. Custom API integration gives you the flexibility to add new tools, enter new markets, and connect new data sources without overhauling your entire technology stack.
According to MuleSoft's 2025 Connectivity Benchmark report, the average enterprise uses 1,061 applications — yet only 29% of them are integrated. That gap costs companies an estimated $500,000 per year in lost productivity and manual workarounds.
API integration closes that gap. It improves data accuracy across every system, supports better analytics and reporting, and ensures your team always works with the most current information when making decisions.

Your team spends hours re-keying data from your CRM into accounting software, or exporting spreadsheets from one platform to import into another. Custom API integration automates this exchange, saving time and eliminating transcription errors that compound downstream.
Your ERP, CRM, marketing tools, and support platform each hold a piece of the picture — but none of them share it. API integration connects these platforms so every department works from the same data, in real time, without manual syncing.
A customer updates their address in your support portal, but the sales team still sees the old one. When systems aren't integrated, data drifts apart fast. API integration synchronizes records across platforms automatically, keeping every system accurate and current.
Growth means new tools, new partners, and new channels — each with its own system. API integration lets you plug in new platforms quickly without rebuilding your existing infrastructure. Your technology stack evolves alongside your business instead of holding it back.
Generating an invoice after every sale, updating inventory after every order, notifying a team after every support ticket — these routine tasks shouldn't require a person. API integration connects your systems to trigger these workflows automatically, freeing your team for higher-value work.
Older software often lacks modern API endpoints, making it difficult to connect with cloud-based platforms. We build custom middleware and adapters that bridge your legacy infrastructure with modern applications — no full system replacement required.

Every integration project is different. A payment gateway connection requires different architecture than a real-time ERP sync or an IoT data pipeline. Here are the API integration services and API development services we deliver — each tailored to your systems, your data, and your business goals.
When no off-the-shelf API exists for your use case, we build one from scratch. Our custom API development services create secure, well-documented, and scalable APIs designed around your specific data structures, workflows, and performance requirements. Whether you need an internal API to connect proprietary systems or a public API for partners and customers, we handle architecture, development, testing, and documentation.
Connect your business with the platforms your team already uses — Salesforce, HubSpot, Stripe, PayPal, Shopify, QuickBooks, and hundreds more. We handle authentication, data mapping, error handling, and rate limiting so the integration works reliably in production, not just in a demo.
REST APIs are the standard for modern web services. We design and integrate RESTful APIs that follow best practices for naming conventions, versioning, pagination, and error responses — delivering fast, lightweight integrations that scale cleanly as your data volume grows.
Many enterprise systems — particularly in healthcare, finance, and government — still rely on SOAP-based web services. We build and maintain SOAP API integrations with full support for WSDL contracts, WS-Security, and XML schema validation.
As your integration landscape grows, you need centralized control. We implement API gateway solutions that handle authentication, rate limiting, traffic monitoring, caching, and logging — giving you visibility and governance over every API call flowing through your systems.
Breaking a monolithic application into microservices creates dozens of internal APIs that need to communicate reliably. We design integration patterns — event-driven messaging, service meshes, and API orchestration — that keep your microservices architecture responsive and resilient.
Your mainframe or on-premise ERP doesn't have a modern REST API — but it still holds critical business data. We build custom middleware, adapters, and wrappers that expose legacy functionality through modern API interfaces, connecting older systems with cloud-based applications without a full rewrite.
An integration is only as reliable as its testing. We perform contract testing, load testing, security testing, and end-to-end validation for every API integration we build. Our QA process catches edge cases, authentication failures, and data format issues before they reach production.
Connect your on-premise systems with AWS, Azure, and Google Cloud services. We build cloud API integrations that handle data migration, hybrid architectures, serverless triggers, and multi-cloud strategies — ensuring your cloud investment delivers real operational value.
Moving data between systems — whether as a one-time migration or ongoing real-time sync — requires careful mapping, transformation, and validation. We build data synchronization pipelines that keep your systems in lockstep, with automated conflict resolution and audit logging.
Connected devices generate continuous streams of data that need to reach your analytics platforms, dashboards, and business systems. We build IoT API integrations that handle high-frequency data ingestion, protocol translation (MQTT, CoAP, HTTP), and real-time processing at scale.
Every business runs on multiple systems. The problem is getting them to talk to each other. Tizbi builds custom API integrations that connect your tools and eliminate the manual data transfers that slow your team down. Here are the systems we work with most often.
We integrate with SAP, Oracle, Microsoft Dynamics, and NetSuite to connect your enterprise resource planning with the rest of your technology stack. Whether you need real-time inventory updates flowing to your e-commerce platform or financial data syncing with your reporting tools, we build integrations that handle the complexity of ERP data models.
Salesforce, HubSpot, Zoho, and Microsoft Dynamics CRM are among the platforms we connect. Our integrations ensure that customer data, deal pipelines, and communication histories stay synchronized across your sales, marketing, and support tools without anyone manually copying records.
We build integrations for Shopify, Magento, WooCommerce, and BigCommerce that sync orders, inventory, customer data, and product catalogs with your backend systems. Real-time inventory accuracy and automated order processing are two of the highest-ROI integrations we deliver.
Stripe, PayPal, Square, Braintree, and custom payment gateways all require reliable, secure integration. We build payment flows that handle transactions, refunds, subscription billing, and compliance requirements while keeping your financial data synchronized across systems.
Healthcare integration requires specialized knowledge of HL7, FHIR, and HIPAA compliance. We connect electronic health record (EHR) platforms, lab systems, pharmacy systems, and patient engagement tools with the security and data governance that healthcare demands.
Not every system has a modern API. We build custom middleware, data transformation layers, and adapter services that connect legacy systems, proprietary databases, and internal tools with the rest of your technology ecosystem. If your system stores data, we can integrate it, regardless of how old the technology is.
Your customers don't see your internal systems — but they feel the consequences when those systems aren't connected. Slow order processing, duplicate information requests, and inconsistent data across touchpoints erode trust fast. According to Salesforce's 2025 State of the Connected Customer report, 80% of customers say the experience a company provides is as important as its products.
API integration eliminates the friction your customers feel. Payment processing becomes instant. Order status updates flow to the customer in real time. Support agents see the full customer history — purchases, tickets, communications — in one view, instead of toggling between four different platforms.
The result is a seamless experience that builds loyalty and drives repeat business. When your systems work together behind the scenes, your customers get faster responses, accurate information, and personalized service without your team working harder to deliver it.
Integrated systems also let you adopt new customer-facing features quickly. Add a chatbot that pulls live order data. Launch a self-service portal that connects to your billing system. Roll out personalized product recommendations powered by real-time purchase history. Each of these depends on solid API integrations running underneath.
We've delivered API integration projects for healthcare, financial services, eCommerce, manufacturing, and SaaS companies. With 400+ completed projects across 28 years, we've solved integration challenges in systems most teams haven't encountered.
No two integration projects are the same. We analyze your existing architecture, data flows, and business rules before writing a single line of code — ensuring the integration fits your systems, not the other way around.
You'll know exactly what we're building, why, and how long it will take. We provide clear project visibility, regular progress updates, and tight daily budget control. No surprises. No scope creep. Just honest collaboration with a team that treats your business like our own.
Tizbi works hands-on with businesses and enterprises, understanding what technological solutions truly deliver results. As your partners in digital transformation — not just a vendor — our developers bring deep integration expertise, rigorous quality assurance, and a commitment to getting it right the first time. Whether you need to connect two systems or orchestrate data across a complex enterprise stack, we build API integrations that run reliably in production, day after day.

API integration is the process of connecting different software systems through Application Programming Interfaces so they can share data and trigger actions automatically. For example, connecting your CRM to your accounting software so new deals automatically generate invoices. It eliminates manual data transfer, reduces errors, and lets your systems work as one coordinated environment.
Cost depends on the number of systems being connected, data complexity, security requirements, and whether you need custom API development or are integrating existing third-party APIs. A straightforward two-system integration typically starts in the low five figures, while complex enterprise integrations involving legacy systems, custom middleware, and real-time synchronization cost more. We provide detailed estimates after a free discovery consultation.
We integrate virtually any system that has an API, database access, or data export capability. That includes ERPs (SAP, NetSuite, Microsoft Dynamics), CRMs (Salesforce, HubSpot, Zoho), eCommerce platforms (Shopify, WooCommerce, Magento), payment processors (Stripe, PayPal), cloud services (AWS, Azure, Google Cloud), and custom-built proprietary applications. For legacy systems without modern APIs, we build custom middleware adapters.
A straightforward integration between two modern systems with well-documented APIs typically takes four to six weeks, including testing and deployment. More complex projects — involving multiple systems, legacy platforms, custom API development, or real-time data synchronization — may take eight to sixteen weeks. We define timelines during the discovery phase and provide milestone-based schedules.
Yes. This is one of our core strengths. We build custom middleware layers, API wrappers, and database adapters that expose legacy system functionality through modern REST or SOAP interfaces. This approach lets you connect older software to cloud-based applications and new platforms without replacing the legacy system entirely. Learn more about our legacy system integration approach →
API integration connects existing systems by configuring and coding against their existing APIs. Custom API development builds a brand-new API from scratch — typically when your proprietary system doesn't have one, or when you need to expose your data or functionality to external partners. Many projects involve both: building a custom API for an internal system, then integrating it with third-party platforms.
The most common methods are REST API integration (lightweight, widely used for web services), SOAP integration (XML-based, common in enterprise systems), webhook-based event triggers, middleware and integration platforms (like MuleSoft or custom-built orchestration layers), and direct database integration for systems without APIs. We recommend the right method based on your systems, data volume, and real-time requirements.
Yes. APIs evolve — third-party providers release new versions, your systems change, and data volumes grow. We offer ongoing monitoring, maintenance, and optimization packages that keep your integrations running smoothly. This includes proactive version management, error monitoring, performance tuning, and adapting integrations when your business requirements change.
We have delivered API integration projects across healthcare and pharmaceuticals (HIPAA-compliant data exchange), financial services (secure transaction processing), eCommerce and retail (inventory and order management), manufacturing and logistics (supply chain connectivity), SaaS and technology (multi-platform data orchestration), and professional services (workflow automation). Our 28 years of cross-industry experience means we understand the compliance, security, and data requirements specific to each sector.
