Enterprise API Development & Integration Services

API integration services connect your business systems through APIs so data moves between them automatically instead of being re-keyed by hand. Wizr AI designs reliable, versioned APIs and streamlines integrations across ERP, CRM, payment, and other business systems, using generative AI to accelerate schema mapping and automate documentation. For finance operations, our AI agents integrate with SAP, Oracle Fusion, and QuickBooks to cross-reference invoices against purchase orders, apply payments, and update ERP records with validated data. For a leading US-based cloud services provider, agentic AI transformed Oracle bank reconciliation, achieving 99.5% accuracy.

Custom API development makes sense when pre-built connectors don’t match your workflows, data structures, or security requirements, or when you need to connect a legacy or in-house system that has no connector at all. Wizr AI assesses your systems and integration needs, then designs custom, versioned APIs around how your business actually runs, while reusing APIs, SDKs, and reusable components where they already fit. That balance avoids paying for custom work where a standard connection is enough, and avoids forcing your processes into a connector that wasn’t built for them.

Yes. Wizr AI introduces APIs that let legacy applications exchange data with modern cloud and SaaS systems, so you don’t need a risky rewrite to get value from them. For a healthcare document processing platform, a Backend-for-Frontend layer securely connects a new interface to existing core services without disrupting existing systems. Where a system needs deeper change, API work becomes part of our broader legacy modernization services, including re-platforming into cloud-native, containerized architectures, delivered in phases so business-critical applications keep running.

Wizr AI delivers Oracle Fusion and Oracle E-Business Suite integrations with secure access to enterprise data, and multi-system integration across ERP, CRM, banking, and payment platforms. Our finance and accounting AI agents integrate with SAP, Oracle Fusion, and QuickBooks to match invoices, apply payments, reconcile bank statements, and update ERP records, with audit trails for compliance. We support flexible cloud deployment across OCI, Azure, AWS, and GCP, and bring proven experience deploying agentic AI across Oracle Finance workflows. For one cloud services provider, Oracle bank reconciliation reached 99.5% accuracy.

Secure API integration starts with how the work is delivered. Wizr AI is SOC 2 Type II and ISO 27001 certified and supports GDPR compliance, with a security framework built on five pillars: least-privilege data access control, end-to-end encryption for data at rest and in transit, continuous monitoring and auditing, security by design, and secure data processing. We implement secure integrations across your existing technology ecosystem and can build authentication and role-based access control into the applications we connect. No integration is secure by default, so security requirements are defined during assessment, not after launch.

Integrations stay reliable when they are versioned, documented, tested, and monitored. Wizr AI designs versioned APIs so systems can evolve without breaking the applications that depend on them, uses generative AI to automate documentation and simulate test traffic before release, and applies AI-driven SLA monitoring to maintain reliability after launch. CI/CD pipelines with AI-powered policy checks and drift detection keep environments consistent, so changes move through testing and deployment the same way every time, instead of being patched by hand when something breaks.

Yes. AI agents need secure access to the systems where work happens. Wizr AI equips AI agents with pre-built and custom tools to securely interact with enterprise applications, data, and systems, and designs agentic workflows that connect AI agents, enterprise systems, and business logic. We integrate AI agents with CRM, ITSM, collaboration, and productivity systems, including Salesforce, ServiceNow, Zendesk, Jira, Slack, and Outlook. For a leading US automotive firm, AI agents integrated through APIs with dealer systems helped save $2.1 million a year.

API integration connects systems through defined interfaces that applications call directly, which is how most enterprise systems exchange data today. MCP (Model Context Protocol) is a newer standard designed to give AI models and agents a consistent way to discover and use tools and data sources. The two are complementary rather than competing: many AI agent setups still depend on well-designed APIs underneath. Wizr AI helps you design the API layer your applications and AI agents rely on. For a deeper technical comparison, read our guide to MCP vs. API integration for enterprise AI.

Yes. SaaS API integration is a common need for software companies whose customers expect the product to connect with the tools they already use. Through our AI product engineering services, Wizr AI helps SaaS and software product companies build, modernize, and scale their products, and our engineers design versioned, documented APIs so each new integration doesn’t create a maintenance burden, and AI-driven SLA monitoring keeps them reliable once customers depend on them.

API integration timelines depend on the number of systems involved, the quality of their existing APIs, data complexity, security and compliance requirements, and whether legacy systems need new interfaces. Connecting two modern SaaS tools and integrating an ERP with CRM, banking, and payment platforms run on very different schedules, so we don’t give one-size-fits-all estimates. Wizr AI starts by assessing your systems and integration needs, so you have a realistic plan before development begins. AI-powered engineering also shortens delivery: Glidepath SDLC AI accelerates the SDLC by up to 40–50%.

The cost of API development and integration services depends on the number and type of systems, whether custom APIs are needed or existing ones can be reused, data and security requirements, testing and monitoring needs, and the engagement model you choose. Wizr AI scopes these factors during the integration assessment, so you can compare options before committing. Reusing APIs, SDKs, and reusable components where they fit reduces build effort, and AI-powered engineering, including a 40–50% developer productivity lift with Dual Loop Engineering, helps keep delivery costs in check.

Talk to an AI expert on our team. Share the systems you need to connect, the data and workflows involved, your security and compliance requirements, and any AI agents you plan to deploy. We’ll help you map the integration landscape, identify where custom APIs are needed, and recommend an engagement model, so you can see how the work would run before committing. A practical starting point is often one high-impact integration, such as ERP-to-CRM or finance automation, with the program expanding once it proves its value.
