SDKs
Embed a native send-and-request flow in your iOS and Android apps: who, amount, review, confirm. The other person claims or pays on a page Moov hosts, not in this SDK.
Your backend mints a short-lived token for the signed-in user and hands it over. See sender authentication. What they see is in What your users see.
A web SDK is in development. Until it ships, a web experience means building on the device API the SDKs use, which isn’t in the public reference yet. Talk to your Moov contact about coding to that contract.
