Small utilities for affiliate attribution work on iOS, Shopify, and custom postbacks. No account, no sign-up, no upload. They run in your browser.

• ASSN v2 decoder

  Paste a signedPayload from App Store Server Notifications v2 and read it, including the nested transaction and renewal payloads Apple signs separately. Runs in your browser, nothing is uploaded.

• ASSN v2 notification types reference

  Every notificationType and subtype in plain language, with what each one means for affiliate commission. Summarized from Apple's reference and filterable in place.

• Commission calculator

  What an affiliate actually earns on an App Store subscription after Apple's 15 or 30 percent cut. Uses the same arithmetic Attribloom accrues with.

• Shopify order attribution checker

  Paste a Shopify order webhook payload and see which affiliate ref it carries, whether the discount code and ref note conflict, and the commissionable amount in minor units.

• Postback signature generator and verifier

  Build or check the x-ea-signature HMAC header for a conversion postback, with the exact signed string, the clock-skew window, and a copy-paste curl. Your secret stays in the browser.
