01 HTTP headers
Authentication
Every request requires your confidential API secret in the X-API-Key header. Treat your API key as a password: it is stored hashed on our side and is shown exactly once when issued.
| Header | Type | Description |
|---|---|---|
X-API-KeyRequired | string | Your secret reseller API key (sk_live_…, or sk_test_… for the sandbox). |
curl -H "X-API-Key: sk_live_your_secret_key" \
https://sajidofficial.com/api/v1/me02 Quota headers
Rate limits & live quota
Requests are limited to 60 requests per minute per API key. Live budget headers are returned on every response.
| Header | Description |
|---|---|
X-RateLimit-Limit | Allowed requests per 60-second window (60). |
X-RateLimit-Remaining | Remaining requests in the current window. |
X-RateLimit-Reset | Unix epoch timestamp when your quota refills. |
HTTP/1.1 200 OK
Content-Type: application/json
X-RateLimit-Limit: 60
X-RateLimit-Remaining: 59
X-RateLimit-Reset: 178894442403 Guarantees
Atomic settlement & zero-debit idempotency
1. Single-commit atomic settlement
Wallet deduction, order creation and code assignment execute inside one atomic SQLite transaction (
BEGIN IMMEDIATE … COMMIT). If anything fails, funds roll back. You are never debited without an order.2. Idempotent replays (external_order_id)
Pass your internal reference in
external_order_id. If your connection drops and your bot retries, the API returns the original order with"idempotent_replay": true— zero duplicate debits, zero duplicate orders.3. Queue on empty stock
If stock is short, the order is accepted, charged and queued; it is fulfilled automatically (FIFO) the moment stock is added and you receive
order.delivered. A queued order we cannot fulfil is cancelled with a full refund andorder.failed.
04 Simulator
Price calculator
Pricing is a flat unit price per product: final_total = unit_price × quantity / price_per, rounded up to the smallest money unit. price_per is 1 for codes and accounts and 1000 for social media boosts, which are quoted per thousand — a boost at $1.08 / 1k costs $1.62 for 1,500. Preview any order with GET /quote or below (needs a sandbox or live key from the console).
- Unit price
- —
- Total
- —
- PKR (1 USD = 283.54 PKR)
- —
- Stock
- —Will queue
Uses the key entered in the console.
The price calculator needs JavaScript. Use GET /quote for the same numbers.

List available products
Returns the live catalogue with available stock per product. input_type is quantity (buy N units), accounts (send one line per unit in items; input_hint shows the format) or link (a social media boost: send the target URL in link plus a quantity). price_per tells how many units unit_price buys — 1 for codes, 1000 for boosts, so "unit_price": 1.08, "price_per": 1000 reads $1.08 / 1k. min_quantity / max_quantity are the accepted quantity range per order (boosts carry the panel's limits, e.g. min 50 · max 10,000; boosts have no stock to run out of). custom_pricing is true when the product is at or below its low-stock buffer (orders that dip into the buffer must send accept_normal_price: true).

Architecture & cryptographic verification
Webhooks remove polling. Whenever an order is delivered, queued or fails, we push a signed HTTPS POST to your endpoint (retried with backoff for up to 6 attempts: 1 m, 5 m, 30 m, 2 h, 6 h).
order.deliveredCodes are assigned and ready for your customer. Payload includes
products— for a boost, its status line (a partial delivery shows the refunded remainder and a smallerquantity).order.queuedStock is pending restock, or a boost is being delivered by the panel. The order fulfils automatically once restocked / completed.
order.failedThe order was cancelled and fully refunded (
failed_reason).

Python
import hmac, hashlib
def verify_webhook(raw_payload_bytes, signature_header, webhook_secret):
expected = "sha256=" + hmac.new(webhook_secret.encode(), raw_payload_bytes, hashlib.sha256).hexdigest()
return hmac.compare_digest(expected, signature_header)Node.js

const expected = "sha256=" + crypto.createHmac("sha256", secret).update(rawBody).digest("hex");
return crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(signatureHeader));
}PHP
$raw = file_get_contents('php://input');
$expected = 'sha256=' . hash_hmac('sha256', $raw, $secret);
$ok = hash_equals($expected, $_SERVER['HTTP_X_WEBHOOK_SIGNATURE'] ?? '');Respond with any 2xx status within 10 seconds. Anything else is retried.

serverservicelist / imeiservicelist | The catalogue grouped by category: SERVICEID, SERVICENAME, CREDIT (price per unit), STOCK, MINQNT / MAXQNT. Services that need your own accounts expose a CUSTOM field named Accounts. Social media boosts are listed as "… (per 1000)" with CREDIT per 1000, the panel's MINQNT / MAXQNT and a CUSTOM field named Link for the target URL. |
placeserverorder / placeimeiorder | Parameters ID (SERVICEID) and QNT; account lines go in the custom field, a boost's target goes in the Link custom field (a plain LINK / URL parameter works too). A delivered order answers in the same call with STATUS 4 and the codes in CODE (one per <br>); STATUS 1 = queued (boosts stay pending while the panel delivers), refunded automatically if it cannot be fulfilled. |
getserverorder / getimeiorder | STATUS 4 delivered · 1 pending · 3 rejected (refunded), plus CODE — for a finished boost the panel's status line, e.g. Completed · panel order #501 · start count 3572. |
