Edge-first architecture, zero dependencies, and strictly typed. Build subscriptions and payments for Guatemala in minutes.
Building payment integrations by hand using raw fetch is risky. Here are 4 critical technical reasons why this SDK saves you from massive headaches:
Recurrente uses Svix for webhooks. Validating cryptographic signatures by hand means dealing with HMAC hashes, timestamps, and replay attacks. Our SDK reduces this to a single line of code (verifySignature) that runs natively on the Edge, without needing to install the heavy official Svix library.
If a user taps "Pay" and their connection drops, the app might retry the request and charge them twice. This SDK silently injects a unique Idempotency-Key (UUID v4) into every mutation (POST/DELETE), protecting you and your customers without any extra code on your end.
Do APIs throw 429 (Too Many Requests) or 500 errors? The SDK features a smart client with Exponential Backoff. It will wait a few milliseconds and automatically retry the request before throwing an ugly error to the end user.
If you have over 100 payments, fetching them all manually forces you to write ugly while loops parsing cursors. Here, you simply use the autoPagingToArray helper and the SDK makes all the underlying calls until it hands you a flat array ready to use.
