What we don't do

We don't know what your app earns. And we don't want to.

App Store responses contain the price of every product you sell. We never process or aggregate them. Unlike other validation platforms, IAPGUARD has no revenue figure for your app — not in a dashboard, not in a database, not in a sales pitch.

Our pricing has nothing to do with how much money you make, so we have no reason to measure it.

Compare with other providers

What a validation leaves behind

✓Product ID and current entitlement state

✓Your anonymous user identifier

✗Product price and currency

✗Aggregated revenue per app or month

✗Purchase history per user

✗Receipt contents after validation

Integration

Three steps,
then stop thinking about it.

Pick your integration

Unity and Godot have ready-made SDKs that handle all of this for you — there is no code to write. Every other platform calls the REST API directly.

Send the receipt

One POST per completed purchase: the store it came from, the product, the type, and the receipt your app just received.

Act on the outcome

We check it against the store of origin and answer with the validated purchase state. Unlock content only when the result says so.

Read the quickstart

POST /v1/receipt/{appid} · the whole integration

# validate a purchase from any language or backend
curl -X POST https://api.iapguard.com/v1/receipt/yourapplicationid \
  -H "Content-Type: application/json" \
  -d '{
       "store":   "GooglePlay",
       "bid":     "com.company.spacewar",
       "pid":     "coins",
       "type":    "Consumable",
       "user":    "userX",
       "receipt": "ihmndabonhehhfcbiiakbnmp..."
     }'

# Unity and Godot: the SDK sends this for you.

Platform

Everything the store receipt doesn't give you.

A receipt only proves a payment happened once, somewhere. IAPGUARD turns it into state you can build on — for consumables, one-time unlocks and subscriptions alike.

Receipt authenticity

Every receipt is checked against the store it claims to come from. Forged and replayed payloads never reach your unlock logic.

One redemption, ever

Transaction storage makes every validated receipt globally unique, so the same purchase can't be shared between accounts.

Inventory that follows the player

Purchases live in the cloud against your user ID. New phone, reinstall, second device — the entitlement is already there.

Live subscription state

Active, in grace, billing retry, expired — updated by App Store notification servers, not by whatever the device last remembered.

Analytics without a pipeline

Which products sell, which countries buy, how the stores split — from validated data, and without a revenue figure attached.

Webhooks with retries

Validated transactions delivered to your own backend. Failed deliveries queue up and try again, so nothing is silently lost.

Dashboard

See what's actually selling.

Transaction volume by day and month, top products, store split and country breakdown — for every app you run, on one screen.
