Authentication - Quickei Developer Docs

The Partner Payout API uses Bearer Token authentication. Include your API key in every request.

Base URLs

The API has separate URLs for sandbox and production:

Environment	Base URL
Sandbox	`https://quickei.io/api/partner/sandbox/v1`
Production	`https://quickei.io/api/partner/v1`

Use the sandbox URL with sandbox credentials for testing. Use the production URL with production credentials for real transactions.A sandbox token will be rejected on the production URL, and vice versa.

Getting Your Credentials

Go to quickei.io/merchant/login and sign in.

Create API Keys

Go to Developer API > API Keys and generate your keys. You will get separate keys for Sandbox and Production.

Go to Payout API

Navigate to Payout API in the sidebar. You’ll see your credentials for both environments with a toggle to switch between them.

Request Headers

Include the following headers in every request:

Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
Accept: application/json

Example Requests

Sandbox:

curl -X GET https://quickei.io/api/partner/sandbox/v1/balance \
  -H "Authorization: Bearer YOUR_SANDBOX_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json"

Production:

curl -X GET https://quickei.io/api/partner/v1/balance \
  -H "Authorization: Bearer YOUR_PRODUCTION_TOKEN" \

Sandbox vs Production

	Sandbox	Production
Base URL	`/api/partner/sandbox/v1`	`/api/partner/v1`
Credentials	Sandbox API key	Production API key
Real funds	No — simulated transactions	Yes — real money

Never expose your API key in client-side code, mobile apps, or public repositories. All Partner API calls must be made server-to-server.
