_{Prophet 21 API: A Beginner's Guide to P21 Integration}

API for Epicor Prophet 21

Epicor Prophet21 is one of the most popular ERP solutions in the e-commerce industry. Wholesale distributors can use this platform to manage everything from inventory to sales, which can help them run their business more efficiently. ERP platforms help drive sales, improve revenue, and manage all resources effectively.

It allows you to automate different processes and make your e-commerce establishment more streamlined. At B2Sell, we believe that you can only reach the full potential of EPR platforms like P21 if you have a good API.

_{What is an API?}

API stands for Application Programming Interface. It allows two or more applications to communicate with each other and exchange data. It is a series of codes that dictate how applications can communicate safely and work seamlessly together.

For example, if a website wants to embed a product demo video that's hosted on YouTube, it needs an API. If you want your Magento website to connect with your ERP system to provide data and carry out transactions, you need the relevant API.

Distributors often stumble across performance hurdles when they want to integrate their e-commerce portals like websites or mobile apps with their ERP system.

_{What Does API Do?}

APIs that are specifically designed for e-commerce and ERP integration are different from other products. They are scalable, agile, and user-friendly. They can connect to platforms like Magento, BigCommerce, Shopify Plus, and other such popular portals. This allows distributors to pull data about past transactions, map different data fields, and gain insight on customer behavior from their e-commerce portals.

The communication between the two platforms is seamless and automated. If you make any changes in the ERP system, the e-commerce system will also accept the change and adapt accordingly. Automatic updates make managing both platforms easier to ensure your system is in order and all the information available to the customers is up-to-date.

^{What Are the Services Supported by APIs?}

We can offer honest advice and create an efficient B2B online establishment for you using the most efficient tools.

_{What Is the Prophet 21 API?}

The P21 API is a set of endpoints that let external systems read and write data in your Epicor Prophet 21 ERP. Instead of manual data entry or file imports, software talks directly to P21.

_{What data can you access?}

• Products: Item numbers, descriptions, pricing, UOM

• Inventory: Quantities by location, available-to-promise

• Customers: Account details, credit limits, ship-to addresses

• Orders: Create, read, update sales orders

• Invoices: Pull invoice history for customer portals

• Pricing: Customer-specific pricing tiers and contract prices

_{What the API can't do (easily):}

• Complex P21 business logic (custom workflows)

_{Why Distributors Use the P21 API}

Ecommerce integration Connect your Shopify, Magento, or BigCommerce store so orders flow into P21 automatically. No rekeying. Fewer errors.

Mobile sales apps Give reps real-time access to inventory and pricing from their phones. Place orders in the field that sync to P21.

Customer portals Let customers check order status, download invoices, and view their account balance — all pulling live data from P21.

Marketplace sync Sell on Amazon or eBay? The API keeps inventory quantities accurate across channels to prevent overselling.

_{Getting Started: What You Need}

1. API Access Talk to your Epicor administrator or VAR. You'll need:

• API credentials (username, password, or token)

• Endpoint URL for your P21 instance

• Documentation for available endpoints

2. A Development Environment Don't test on production P21. Set up a sandbox or test instance.

3. Integration Tool or Developer Options:

• Pre-built connector (like B2Sell) — fastest to deploy

• iPaaS platform (Celigo, Boomi) — flexible, some coding

• Custom development — full control, highest effort

4. Data Mapping Before you connect anything, map your ecommerce fields to P21 fields:

• Which product ID in your store matches which item number in P21?

• How do customer accounts align?

• What happens when data doesn't match?
