Non-breaking API update: New response fields for /v2/transactions and /v2/invoice

Effective date: 5 September 2025

Overview

We've added optional fields to two v2 endpoints to enrich product metadata. These are additive, backward-compatible changes. No request parameters, pagination, status codes, or rate limits are affected.

Endpoints impacted

1. GET /v2/transactions
2. GET /v2/invoice

What's changing

/v2/transactions

New fields in each item under data[]:

• product_image_url (string, URL): Link to the product logo
• category (string): Product category

/v2/invoice

New fields in each item under data[]:

• product_code (string): Product code
• product_image_url (string, URL): Link to the product logo/image (same convention as transactions)

Backward compatibility

• This is a non-breaking change; existing fields and their formats are unchanged.
• New fields may be null or absent for some records. Clients should handle missing values gracefully.
• If you use strict JSON schema/model validation, ensure your models are updated to include these optional fields or are configured to ignore unknown properties.

Actions for integrators

• No action required to maintain existing functionality.
