💳 Master Zoho Payments Testing with APIDog

Integrating a payment gateway like Zoho Payments can feel complex—but testing your API workflows doesn’t have to be.
In this tutorial, you’ll learn how to use APIDog, an all-in-one API development platform, to test, document, and debug your Zoho Payments integration before writing any production code. This approach helps you catch issues early and build with confidence.

🚀 Why Use APIDog for Zoho Payments?

While tools like Postman or basic cURL commands can work, APIDog provides several advantages, especially for payment-related APIs:
  • Unified Workflow – Design, test, debug, and document APIs in a single interface
  • Mock Servers – Simulate successful or failed payment responses without touching real banking systems
  • Automated Testing – Validate edge cases in flows like Create Payment or Payment Confirmation
Using APIDog allows you to focus on logic and reliability, not trial-and-error debugging.

✅ Prerequisites

Before you begin, make sure you have:
  • A Zoho Payments Sandbox account
      • (or a test organization in Zoho Books / Zoho Checkout)
  • APIDog installed on your system
  • Your Zoho Client ID and Client Secret from the Zoho Developer Console

🛠 Step 1: Set Up Your Environment in APIDog

Start by creating a new project in APIDog for your Zoho Payments integration.
  1. Open APIDog and click New Project
  1. Name the project “Zoho Payments”
  1. Configure Global Variables for easier testing:
      • base_url:
          • https://www.zohoapis.com/billing/v1
          (Use .eu or .in if your data center differs)
      • authorization:
          • This will store your OAuth access token

🔐 Step 2: Authenticate Using OAuth 2.0

Zoho APIs require OAuth 2.0 authentication.

Generate an Access Token

  1. Generate a Grant Token from the Zoho Developer Console
  1. In APIDog, create a POST request to:
      2. https://accounts.zoho.com/oauth/v2/token
  1. Add the following query parameters:
      • client_id
      • client_secret
      • code (grant token)
      • grant_type=authorization_code
  1. Send the request
  1. Copy the access_token from the response
  1. Update your APIDog environment variable with the new token

🔗 Step 3: Test “Create Payment Link”

A common Zoho Payments use case is generating a hosted payment link.

Create the Request

  • Method: POST
  • URL:
      • {{base_url}}/hostedpages

Headers

Authorization: Zoho-oauthtoken {{access_token}}
X-com-zoho-subscriptions-organizationid: {{org_id}}

Request Body (JSON)

{
"customer_id":"9000000000000",
"plan":{
"plan_code":"premium-monthly",
"price":2900
}
}

Run the Request

Click Send.
If successful, you’ll receive a 201 Created response containing the payment page URL.

🔔 Step 4: Validate Webhooks

APIDog makes webhook validation much easier by letting you define expected payload structures.
  1. Navigate to the Schemas section in APIDog
  1. Define the schema for a Zoho “Payment Success” webhook event
  1. Use this schema to validate incoming webhook payloads while building your backend listener
This ensures your application handles real payment events correctly.

🎯 Conclusion

By using APIDog, you separate payment API logic from your application code. This lets you:
  • Test Zoho Payments without real transactions
  • Validate API responses and webhooks
  • Generate ready-to-use code snippets (Node.js, Python, Go, etc.)
  • Integrate confidently, knowing everything works as expected
Once your APIs are verified, you can simply export the generated code and plug it directly into your application.
