Key Takeaways Choose the right Remitly approach: Partner APIs vs Connected Experiences SDK depending on how embedded you want the experience to be. Production success depends on webhooks + reconciliation, not just synchronous API calls. The biggest risks are poor error handling, weak observability, and unclear operational ownership. A strong integration partner ships with clean architecture, tests, runbooks, and monitoring, not just code. Which Remitly integration path fits your product In broad terms, you’ll typically see two practical routes: 1) Partner API style integration (server-to-server) Best if you: Need deeper control over your own UX and orchestration Want to manage business logic, routing, or internal ledgering Have an experienced backend team and a mature platform Remitly provides Partner Hub API documentation (including an OpenAPI spec download in their sandbox docs), which signals a structured partner integration approach. 2) “Connected Experiences” SDK integration (embedded flow) Best if you: Want a faster time-to-market with a guided experience Prefer using an SDK to embed a Remitly-powered transfer experience Need mobile/web SDK support for common platforms Remitly’s open-source “Connected Experiences” SDK repositories (e.g., React Native, iOS, Android, web) indicate SDK-based integration options for embedding the experience. Rule of thumb: If your product is fintech infrastructure → Partner-style API integration often fits. If your product is a consumer app / marketplace that needs a transfer feature quickly → SDK route can be compelling.
