Introduction to Template Rendering APIs: Transform Your Data Dynamically

Published: September 29, 2025 | 5 min read

What is a Template Rendering API?

In today's data-driven world, developers constantly need to transform structured data into various formats - HTML for web pages, JSON for APIs, XML for integrations, or plain text for emails. A **template rendering API** automates this transformation process, saving countless hours of development time.

Why Use a Template Rendering API?

1. Separation of Concerns

Keep your data logic separate from presentation logic. Your backend focuses on data, while templates handle formatting.

2. Reusability

One template can serve thousands of requests with different data, reducing code duplication.

3. Non-Developer Friendly

Business users can modify templates without touching code, speeding up iterations.

How Template Rendering APIs Work


Data (JSON) + Template (Scriban) = Output (Any Format)

Example: Invoice Generation

*Your Data:*


{
  "customer": "Acme Corp",
  "amount": 1299.99,
  "items": ["Premium Plan", "Setup Fee"]
}

*Your Template:*


Invoice for {{ customer }}
Total: ${{ amount }}
Items:
{{ for item in items }}
- {{ item }}
{{ end }}

*Result:*


Invoice for Acme Corp
Total: $1299.99
Items:
- Premium Plan
- Setup Fee
