APIs vs Templates: Get Your Product Data Where It Needs to Be

Managing the content you publish is hard enough, but the delivery of your content is where things frequently go sideways. 

Thankfully, there are two main product data syndication engines: APIs and templates.

In this guide, we’ll look at the differences between these export methods, examine their advantages and limitations, and help you decide which product feed delivery strategy is right for your business.

What is Product Data Syndication?

So, what’s product data syndication, anyway? Well, this refers to the process of exporting, formatting, and delivering your content to platforms like Amazon, Walmart, Shopify, and others. 

This can include structured information like:

  • Titles and descriptions
  • SKUs, GTINs, and internal IDs
  • Product attributes and data variants
  • Pricing, availability, and shipping details
  • Media assets (images, videos, documents)
  • SEO metadata and enriched content

Without automated syndication, your teams spend hours copy-pasting into spreadsheets. As you can imagine, this leads to both inconsistencies and error that can see your listings rejected – and can lead your customers to leave your shop.

Why Product Data Syndication Matters

If you’re not syndicating data properly, you’re likely facing:

  • Channel compliance issues
  • Delayed product launches
  • Disorganized product feed delivery
  • Inconsistencies with SKU-level content
  • Lost sales due to listing errors

The best-performing e-commerce brands treat syndication as a core capability – APIs and templates are just the tool to meet this requirement.

What Is an API?

An API (Application programming interface) is a software connector which allows systems to communicate in real time. In other words, your PIM can push product data directly from your system to the platform of your choice. 

Examples of PIM API Integrations:

  • Shopify API – Automatically updates product listings and inventory
  • Amazon Selling Partner API – Sends content, pricing, and stock info
  • ERP integrations – Synchronizes real-time inventory or product cost updates
  • Digital Asset Management (DAM) APIs – Pulls images and videos from a DAM to your PIM

APIs enable instant and automated product data delivery, and remove manual work from your syndication process.

What Is a Product Data Template?

A product data template is a pre-structured file that conforms to your channel’s requirements. The template is often issued in CSV, Excel, or XML format. 

Each platform may have its own template. For instance:

  • Amazon Flat Files
  • Walmart Marketplace XLSX
  • Google Shopping Feed CSV
  • Custom distributor content forms

Typically, templates are uploaded manually or via SFTP, and formatting perfection is essential. Each column should be ordered correctly and contain complete, accurate data. 

APIs vs Templates: A Side-by-Side Comparison

Let’s break down the key differences between APIs and templates for product data syndication.

Feature

APIs

Templates

Speed

Real-time

Manual or scheduled

Ease of Setup

Requires development

Pre-defined formats

Flexibility

Dynamic updates, bi-directional

Limited to fixed fields

Error Handling

Real-time validation

Often post-upload errors

Channel Support

Works with platforms offering APIs

Required where APIs aren’t available

Best For

Ecommerce platforms, marketplaces

Distributors, retailers, custom channels

As you can see, APIs are great for automation, while templates are essential for structured delivery to platforms that may not offer integrations.

PIM API Use Cases: When APIs Are the Right Fit

    If your e-commerce stack supports it, PIM API integration can transform how you manage your product content.

    Common API Use Cases:

    1. Real-Time Sync with Your Ecommerce Store

    If you list on Shopify or BigCommerce, APIs can keep your catalog synced 24/7. Each and any change in the PIM, such as title or image, is reflected instantly.

    1. Feed Automation to Marketplaces

    Using an API to send data to platforms like Amazon, eBay, or Target+ ensures that your listings are compliant and up to date. There’s no need to re-upload your templates. 

    1. Bi-directional Sync with ERP or Inventory Systems

    A PIM API can pull pricing and inventory data from your ERP, sending back enriched data for consistent operations. 

    1. Programmatic Validation

    An API will handle errors automatically. You can catch invalid values before they go live, ensuring compliance and reducing rejection rates.

    Template-Based Syndication: When Templates Work Best

    Many distributors require you to use custom templates to submit your data. Few offer an API for your convenience. Let’s take a look:

    Common Template Use Cases:

    1. Distributors Requiring Custom Product Feeds

    Many wholesalers and distributor portals use their own CSV or Excel templates, each with different column names and data requirements.

    1. Retailers with Static Requirements

    Retailers like Lowe’s or Home Depot may provide Excel files you must complete monthly.

    1. Government or Regulated Channels

    If you sell medical or industrial equipment, for example, you may need to deliver product data in highly structured, non-API formats to maintain compliance.

    1. Smaller Channels Without API Support

    Some regional marketplaces or legacy ERP systems can only ingest product feeds via FTP or email… templates are the only “way in.”

    Key Challenges with Each Method

    Even the best systems come with their own set of challenges. Here’s what to look out for:

    Challenges with APIs:
    • Requires development resources for integration
    • May need ongoing maintenance when APIs change
    • Not all platforms have public APIs
    • Error messages can be complex without robust logging

     

    Challenges with Templates:
    • Manual processes increase workload and the risk of human error
    • Inconsistent formats across partners may lead to rejection if the information your feed is not formatted to spec
    • Data validation happens after submission, often leading to rework

     

    Scaling is difficult and time-consuming without automation

    Best Practices for Choosing Your Syndication Strategy

    Here’s how to decide whether to use APIs, templates, or both:

    Question

    Strategy

    Does the platform offer a public API?

    Use API for real-time automation

    Is the channel requiring structured templates?

    Use template-based exports

    Do you have internal dev resources?

    Lean into APIs for long-term scale

    Are there frequent changes to product data?

    Use APIs to reduce manual updates

    Are you sending to B2B distributors or retailers?

    Templates or SFTP likely required

    In most cases, the answer is a resounding yes to both.

    Final Thoughts: Get Your Product Data Where It Needs to Be

    Whether you’re working with Shopify, Amazon, a niche marketplace, or a network of business-to-business distributors, your product data must arrive fast, formatted, and flawless.

    Your API brings automation and speed to your operations. Your templates bring structure and compatibility. But without a centralized system to manage the data, even the best strategy can fall short. 

    Growing e-commerce brands rely on PIM platforms like Catsy to simplify product content and simplify exports. This ensures that each SKU is delivered precisely correctly, no matter on which platform the data will live.
