As answered by people managing DevFinanceTools and WalletWallet.dev.
WalletWallet.dev's answer:
Developers and small teams adding wallet passes to a product they already run. Typical use cases are loyalty cards for cafes, gyms and shops, membership cards for libraries and studios, event and cinema tickets, season passes, coupons and gift cards. Agencies also use it to build white-label loyalty for their clients.
WalletWallet.dev's answer:
Hosted on Cloudflare Workers, so pass generation runs close to the caller worldwide. Updates are pushed to Apple over APNs and to Google over server-side push. The docs are also published in agent-readable form at walletwallet.dev/llms.txt, so a coding agent can wire up the integration.
WalletWallet.dev's answer:
You do not need an Apple Developer account or a Google Wallet issuer account. We run the signing and issuer infrastructure for both platforms, so you can ship a pass in your first hour instead of waiting on Apple to verify a developer account. One POST returns a signed .pkpass and a Save to Google Wallet link at the same time, and a pass that lands on both wallets counts once.
WalletWallet.dev's answer:
Three reasons. One call issues to both wallets, so you are not integrating Apple and Google separately, and a pass on both counts once. There is no certificate or issuer setup, because we sign and issue with our own. And the full lifecycle is covered: a PUT updates a live pass and pushes the change to every phone it is installed on, a DELETE revokes it. Pricing is flat at $39 a month for 100,000 passes, with a free tier at 1,000.
WalletWallet.dev's answer:
We wanted a few wallet passes for another project and hit the Apple Developer wall: $99 a year and a multi-step certificate setup before you can sign anything. The API providers around at the time still required you to bring your own developer account, so they saved you the code but not the setup. WalletWallet started as the missing piece: call one endpoint, get a signed pass back, no certificate work at all. Google Wallet support followed on the same principle, with no issuer account to create.
WalletWallet.dev's answer:
We don't publish customer names without their permission. The active base is small teams across these segments: - Cafes and small retailers running loyalty programs - Event organizers and venues issuing tickets - Agencies building white-label loyalty for their clients - Indie developers shipping a membership or ID card inside their own product
