What Is an Application Connector? How It Simplifies EDI Integration

Businesses today rely on an average of 110 different SaaS applications, which makes getting systems to communicate a major operational challenge. For example, a company running NetSuite ERP might need to share documents via electronic data interchange (EDI) with retailers such as , , or . These systems use different communication methods and don’t speak the same technical language out of the box.

Application connectors help bridge those gaps, acting as the link that lets software systems share information smoothly, even when each system handles data differently. The challenge is that traditional often require businesses to build separate connectors for every trading partner, creating a process that’s difficult and expensive to maintain.

This guide explains what application connectors are, how integration, and how modern platforms eliminate connector complexity.

Application Connector Definition

An application connector is software that enables different business applications to exchange data across systems with different formats or communication methods, automating tasks that would otherwise require manual data entry.

Application Connector Basics

Often called an API connector, integration connector, or data connector, an application connector is pre-built software that lets two systems exchange data. It works as a translator that converts information into a format the receiving system understands.

Application Connector Analogy

Think of an API as the doorway into an application and the connector as the key that opens it. The API defines how applications communicate, including what data they can send or receive, and the connector carries out data exchange based on those rules.

Common Application Connector Use Cases

• Sync customer data from a CRM like Salesforce into a marketing automation tool such as HubSpot.

• Connect an enterprise application, such as NetSuite or SAP, with an eCommerce storefront like Shopify.

• Move financial data from accounting software like QuickBooks into a payment or billing system.

• Link an ERP to EDI software to exchange purchase orders, invoices, and other trading partner documents.

Key Components of an Application Connector

• Authentication: Manages credentials, tokens, and certificates to ensure trust.

• Data transformation: Converts data into the format the receiving system expects.

• Error handling: Detects failures, retries when possible, and logs issues.

• Workflow orchestration: Executes tasks in the correct sequence.

Application Connectors vs. APIs: Understanding the Difference

APIs and application connectors each play distinct roles in how B2B systems communicate. Each does its part to make integrations hassle-free, but understanding the distinction will help you choose the right approach for connecting business applications.

What’s an API?

An API is a set of rules that establishes the technical foundation for system integrations, but it doesn’t move data on its own. It defines how one application can request information from another, including what data is available and which methods are supported.

What Does an Application Connector Do?

An application connector uses APIs behind the scenes to automate data exchange between systems. It hides the complexity of working directly with API calls by providing a ready-made connection path, making integration more accessible for smaller IT teams or non-developers.

API and Application Connector Relationship

APIs expose the data and operations that other systems can access, while connectors perform the requests needed to send or receive that information.

For example, Salesforce offers an API that lets external systems read or update customer records. A Salesforce connector uses that API to automatically sync customer data from your ERP, with no custom coding required.

The Role of Connectors in EDI Integration

EDI is essential for exchanging business documents with trading partners, but ERP systems don’t generate or interpret EDI natively. Companies need a reliable way to translate data between internal applications and external partners, and application connectors fill that gap. Modern, API-first EDI systems like Orderful simplify this even further.

Traditional EDI Integration with Connectors

An ERP stores order, inventory, or invoice details in its own format, while trading partners expect those details in specific EDI formats like ANSI X12 or EDIFACT. A connector pulls information from the ERP, prepares it for EDI processing, and routes it to the appropriate system. Traditional EDI systems often require a separate connector for each partner, creating point-to-point connections that take months to build and maintain.

How EDI Connectors Work

1. Extract ERP data: The connector retrieves new or updated records, such as purchase orders, in an XML format.

2. Convert to EDI: It maps ERP fields to partner specifications and checks for missing or invalid information.

3. Transmit the file: The connector sends the EDI document using the partner’s required protocol, such as AS2, SFTP, or a VAN.

4. Process acknowledgements: When the partner returns an EDI 997 or other confirmation, the connector captures the response and updates the ERP.

Reverse Flow Through EDI Connectors

1. Inbound documents such as EDI 856s or EDI 810s arrive through the same protocols.

2. The connector converts the file into the ERP’s internal structure.

3. The ERP updates automatically once processing is complete.

Challenges With a Traditional EDI Connector

Partner-specific requirements vary widely, often forcing companies to configure separate connectors for partners such as Walmart, Target, and Amazon. ERP updates can break existing integrations, and building a connector for a single partner can take months. Maintaining dozens of connectors places a heavy burden on IT teams and increases long-term costs.

Types of Application Connectors: Pre-Built vs. Custom

Application connectors vary in how they’re built and maintained. Understanding the differences helps companies choose the method that aligns with their systems, timelines, and long-term maintenance needs.

Pre-Built Application Connectors

Integration platforms create and maintain prebuilt connectors that provide fast, reliable integration with systems like Salesforce or QuickBooks. Because they come configured for common data flows, teams can deploy them much faster than building a connector from scratch.

With pre-built connectors, the provider manages updates, compatibility changes, and security adjustments. Orderful offers pre-built ERP connectors that help businesses exchange data with trading partners efficiently.

Custom Application Connectors

Custom connectors support systems that don’t have pre-built options or require unique data handling. They give teams full control over how data is exchanged, converted, and validated. However, they take longer to create and must be updated internally whenever either system changes.

When to Choose Pre-Built vs. Custom Connectors

Pre-built connectors are ideal for widely used systems and teams that want quick deployment without extensive development. Custom connectors suit proprietary or legacy systems with highly specific requirements.

Modern EDI integrations simplify this further by replacing individual partner connectors with a single API integration that supports all partners through a single unified connection.

The Modern Alternative: API-First EDI: How Orderful Eliminates Connector Complexity

Traditional EDI systems rely on building separate connectors for each trading partner, which becomes harder to scale as a business grows. API-first EDI lets companies connect once and exchange data with any partner through a single integration. Orderful uses this model to simplify implementation, reduce maintenance, and remove the need for dozens of custom connectors.

Why Traditional EDI Connectors Do Not Scale

Point-to-point integrations multiply quickly as companies add partners, and each partner may have its own configuration, mapping, and testing requirements. Projects can take months, especially when partners enforce strict formatting or validation rules. IT teams must revisit connectors every time requirements change, leaving businesses with fragile integrations that are costly to maintain.

Application Connector FAQs

What is an application connector?

An application connector is software that enables different business applications to exchange data across systems with different formats or communication methods, automating tasks that would otherwise require manual data entry. Often called an API connector, integration connector, or data connector, it acts as a translator that converts information into a format the receiving system understands. Application connectors include authentication to manage credentials and security, data transformation to convert formats between systems, error handling to detect failures and retry transmissions, and workflow orchestration to execute tasks in the correct sequence. Common use cases include syncing CRM data to marketing tools, connecting ERPs to eCommerce platforms, moving financial data between accounting systems, and linking ERPs to EDI software for trading partner document exchange.

What's the difference between an API and an application connector?

An API (Application Programming Interface) is a set of rules that defines how one application can request information from another, establishing what data is available and which methods are supported, but it doesn't move data on its own. An application connector uses APIs behind the scenes to automate data exchange between systems, hiding the complexity of working directly with API calls by providing a ready-made connection path. Think of an API as the doorway into an application and the connector as the key that opens it. For example, Salesforce offers an API that lets external systems access customer records, while a Salesforce connector uses that API to automatically sync customer data from your ERP without requiring custom coding. APIs expose capabilities, while connectors perform the actual integration work.

How do application connectors work in EDI integration?

In EDI integration, application connectors bridge the gap between ERP systems that store data in internal formats and trading partners that require specific EDI standards like ANSI X12 or EDIFACT. The connector extracts data from the ERP (like purchase orders), converts ERP fields to partner specifications and validates the information, transmits EDI documents using required protocols like AS2, SFTP, or VAN, and processes acknowledgments by capturing partner responses and updating the ERP. For inbound documents, the connector receives EDI files from partners, converts them into the ERP's internal structure, and updates the ERP automatically. Traditional EDI requires separate connectors for each trading partner, creating point-to-point connections that take months to build and maintain, while modern API-first platforms eliminate this complexity.

What are the challenges with traditional EDI connectors?

Traditional EDI connectors create significant operational challenges as businesses scale. Each trading partner requires a separate connector with unique configurations for partners like Walmart, Target, and Amazon, multiplying integration complexity. Building a single partner connector can take months due to custom mapping, testing, and validation requirements. ERP updates frequently break existing integrations, requiring IT teams to rebuild or reconfigure connectors. Maintaining dozens of point-to-point connections places heavy burdens on IT resources and increases long-term costs. Partners enforce different formatting rules, protocols, and timing requirements, making standardization impossible. This fragile architecture creates technical debt that compounds over time as partner networks grow, leaving businesses with costly, difficult-to-maintain integration landscapes.

Should I use pre-built or custom application connectors?

Pre-built application connectors are ideal for widely used systems like Salesforce, NetSuite, QuickBooks, or SAP when you need fast deployment without extensive development work. Integration platforms create and maintain these connectors, managing updates, compatibility changes, and security adjustments automatically, reducing IT burden. Orderful offers pre-built ERP connectors that accelerate EDI integration. Custom connectors suit proprietary or legacy systems without pre-built options, or businesses with highly specific data handling requirements that pre-built solutions can't accommodate. Custom connectors provide full control over data exchange, conversion, and validation but require longer development timelines and ongoing internal maintenance whenever either system changes. Most businesses benefit from pre-built connectors when available, reserving custom development only for truly unique integration requirements.
