Invoicing API
32 followers
In Spain, every invoice now has to be tamper-proof and reported to the tax agency. That's Verifactu, and building it yourself eats a quarter of engineering time. BeeL is one API that just does it. Point us at your payments and each charge becomes a legal invoice, filed with the tax agency and emailed to your customer. One click on Stripe, no code — or wire the API into your product. REST, SDKs, and a CLI so Claude Code or any AI agent can invoice. Free sandbox, no limits.
@pvallsv nice launch congrats🙌love that you built webhooks for this. Are webhook payloads signed so we can verify they actually came from BeeL?
@vikramp7470 Thanks! 🙏 Yep, everything we send is signed. The header looks like this: BeeL-Signature: t=,v1= v1 is an HMAC-SHA256 of ".", keyed with the webhook secret you get when you create the subscription. We only show it once, so store it somewhere safe. Two gotchas when you implement it. The HMAC covers the raw bytes, so verify before anything parses the JSON (express.json() will bite you here). And reject anything where the timestamp is more than ~5 min old, otherwise replays go through. Use a constant time compare too. If you're on Node, @beel_es/sdk already does all of this for you. There's also a BeeL-Event-Id header. Retries and manual redeliveries keep the same id, so you can dedupe on it. And you can list deliveries via the API if you ever want to see what we actually sent and replay it. Rest is at docs.beel.es. Ping me if anything looks off.
