Product & Service Reseller API

Resell our hosting, servers and licences under your own brand: order at your reseller price, get the account details back at once, and renew, upgrade, suspend or end the services - from your website, your billing system or WHMCS.

REST + JSON API key (Bearer) Paid from your wallet 120 calls / minute v1

Getting started

Sign in and open রিসেলার API in your client area. Ask for reseller access (it may need our approval).
Create your API key - it is shown once, keep it secret. Optionally allow only your server's IP addresses.
Add funds to your wallet: every order is paid from it at once.
Connect: install a ready-made module, use the PHP SDK, or call the API directly as shown below.

API address

BASEhttps://mail.relech.com/api/reseller/v1

Authentication

Send your key with every call in the Authorization header (or as X-Api-Key). Use HTTPS only; never put the key in a browser page. GET /account answers with your balance and your discounts - a good first call.

GET /api/reseller/v1/account HTTP/1.1
Host: mail.relech.com
Authorization: Bearer rk_xxxxxxxx_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Accept: application/json

A new key replaces the old one at once. Too many wrong keys from one address are blocked for a while.

Answers and errors

Every answer is JSON with success. On success the result is in data; on failure error.code tells what happened (stable, for your code) and error.message says it in words. The HTTP status matches.

Success

{
    "success": true,
    "data": {
        "balance": {
            "amount": 200,
            "currency": "USD"
        }
    }
}

Failure

{
    "success": false,
    "error": {
        "code": "insufficient_balance",
        "message": "Your balance does not cover this order. Add funds and try again.",
        "required": {
            "amount": 11.6899999999999995026200849679298698902130126953125,
            "currency": "USD"
        },
        "balance": {
            "amount": 4.20000000000000017763568394002504646778106689453125,
            "currency": "USD"
        }
    }
}

Prices and payment

Your price = our retail price minus the discount of your reseller group.
GET /products gives the retail price and your price of every billing period - import it and add your margin.
Services ordered through the API never renew on their own: renew them with POST /services/{id}/renew before they are due, or they are suspended a few days after.
An upgrade costs the price difference for the rest of the period, at your price.
An order is an invoice in your account, paid from your wallet at once. When the balance is short nothing is ordered.
