Overview

The Uzum FastPay API enables payment processing using Uzum’s FastPay system, covering both payment initiation and fiscalization. The integration is split into two independent stages:
  1. Uzum FastPay Payment – initiates a payment using an amount and QR code.
  2. Fiscalization – confirms the completed payment and registers it with the fiscal system.
This separation ensures reliable payment handling and compliance with fiscal regulations.

​
General Setup

All Uzum endpoints share these common settings:
  • Status code: 200/400/500
  • Method: POST
  • Auth required: No
  • Content-Type: application/json
Note: Even in case of validation, payment, or fiscalization errors, the API returns HTTP 200.
  • Always check is_success and HTTP status code to determine if the request succeeded.
  • data contains the payload on success; error contains details on failure.

​
Payment Flow

A typical Uzum FastPay payment flow consists of the following steps:
  1. The client initiates a payment via the Uzum FastPay Payment API
  2. Uzum processes the transaction and returns a unique payment_id
  3. After successful payment, the transaction is sent for fiscalization
  4. A fiscal receipt is generated and registered in the Soliq system
Each step is handled by a dedicated endpoint.
