sendflow tunnel
API Tunnel (Blaaiz, Payonus & Other Channels)
ValuuCards routes external provider requests (such as Blaaiz and Payonus) through a secure API tunnel. These endpoints cannot be accessed directly via a browser and require proper authentication headers.
Base URL
All tunneled requests start from the same base URL:
https://api.sendflow.tech/api/tunnel/
Channel Path
Each provider has a dedicated channel path.
Blaaiz channel: blaaiz/
Important: The channel path must always be included immediately after the base URL.
Endpoint Structure
https://api.sendflow.tech/api/tunnel/{channel}/{endpoint}
Where:
{channel} is the provider channel (e.g. blaaiz, payonus)
{endpoint} is the last part of the provider endpoint
Example (Blaaiz)
Original provider endpoint: /make_deposit
Tunneled endpoint: POST https://api.sendflow.tech/api/tunnel/blaaiz/make_deposit
{ "status": 412, "response": "Unauthorized Access Denied", "data": [] }
This is expected behavior.
Tunnel endpoints do not support browser access
Requests must include authentication headers
Only server-to-server API calls are allowed
Authentication
All tunnel requests must include valid authentication headers:
Authorization: Bearer YOUR_API_KEY Content-Type: application/json
Requests without authentication will be rejected.
Supported Tunnel Channels
blaaiz
International collections & payouts
payonus
Bank payouts (South Africa)
passpoint
International bank deposits
Key Rules
Always include the channel after the base URL
Never test tunnel endpoints in a browser
Authentication headers are mandatory
Same tunnel pattern applies to all providers
Tunnel URL format:
Base URL + Channel + Endpoint
https://api.sendflow.tech/api/tunnel/blaaiz/make_deposit
