Questions we get about systems integration & apis
Which systems have you integrated?
Razorpay, Supabase, Twilio/Telnyx, SMTP/IMAP mailboxes, hospital HIS exports, NHCX bundles and EDI clearinghouses, among others.
How do you keep integrations safe?
Signed webhooks, DNS-resolved SSRF guards on outbound calls, secret rotation with grace periods and an append-only ledger of every write-back.
Can integrations run without a full rebuild?
That's the point — we sit next to your existing systems and connect them; nothing gets replaced.
