Postman

The collection calls every Merchant API endpoint. A pre-request script adds timestamp, nonce, x-api-key, and x-signature using the canonical form, including \u escapes for non-ASCII names.

Import one environment, replace the placeholder keys, and send. Sandbox and production are separate environments.

The environment files ship with placeholders only: YOUR_SANDBOX_API_KEY, YOUR_SANDBOX_SECRET_KEY, YOUR_PRODUCTION_API_KEY, YOUR_PRODUCTION_SECRET_KEY, and YOUR_KYC_CHANNEL. Put your own keys in Postman after import. Do not commit them.

Import

In Postman, choose Import and select the collection file.
Import the sandbox environment, or the production environment, not both at once unless you mean to switch.
Open the environment and replace each YOUR_… value.
Select that environment in the top-right environment menu.
Send Register KYC for a JPY player before Deposit.

kycChannel is the channel value from InsPay onboarding. It is sent as gateway. That field is required today.

The collection does not contain a live API key or secret. Requests fail until you replace the placeholders and your server IP is allow-listed for that environment.
