Connect your own accounts, keep your own brand
Plug your Resend account into Flowpera and every email we send on your behalf leaves from your verified domain — with your key encrypted and invisible, even to us.
- Send from your verified domain
- Keys encrypted with AES-256-GCM
- Owner-only, never shown to your team
What you can do with api & integrations
The tools you already pay for should work inside Flowpera, not beside it. Connect your own Resend account and every email leaves from your domain — with your credentials encrypted at rest and never returned to a browser, so they stay usable but invisible.
Your domain on every email
Connect Resend once and invoices, reminders and anything else Flowpera sends arrive from your business — not a generic platform address.
Encrypted, never readable
API keys are encrypted with AES-256-GCM before they touch the database and are never returned to a browser. You only ever see the last four characters.
Owner-controlled by design
Only the workspace owner can view or change credentials, while managers with invoice access can still send through the connected account — the key never leaves the server.
Take payments with Stripe
Connect your Stripe account to sell on your storefront, charge for booking and custom forms, and let clients pay invoices online — the money lands in your account, not ours.
Verify before you rely on it
See a clear connection status with real error messages, so you know immediately whether your key and sending domain are actually working — not silence.
Up and running in a few steps
- 1
Open API & Integration
As the workspace owner, head to Settings → API & Integration, where connected accounts live.
- 2
Paste your Resend key
Add your key and sending details. It's encrypted immediately, and only the last four characters are ever shown back to you.
- 3
Send from your domain
From then on, invoices and reminders leave from your verified address, resolved securely on the server so even teammates who can send never see the key.
Built to grow with the tools you use
The integrations layer is provider-agnostic: Resend for email and Stripe for payments both connect the same way, with the same encryption. Newsletter automation is next, so the accounts you already pay for keep working inside Flowpera instead of beside it — and every connection reports its real status, not a shrug.

Built for the way you work
Established brands
Route every client email through your verified domain so invoices and reminders never look like they came from a third party.
Security-minded owners
Store sending credentials encrypted at rest, visible to no one — not your team, not the platform — while staying usable for sending.
Delegating teams
Let a manager with invoice access send through the owner's connected account without ever being handed the key itself.
Questions, answered
Is my API key safe in Flowpera?
Yes. Keys are encrypted with AES-256-GCM before they're stored and are never sent back to a browser. Only the last four characters are ever displayed.
Who can connect or change credentials?
Only the workspace owner. Managers with invoice access can send through the connected account, but they can't view or edit the credentials.
What happens if I don't connect Resend?
Emails still send from the platform's default address. Connecting Resend simply moves them onto your own verified domain.
Can I take card payments through it?
Yes. Connect your Stripe account and you can sell on your storefront, charge for paid forms and let clients pay invoices online — all with your keys encrypted the same way as your email key. See Products & Payments for the selling side.
What's coming next?
The layer is provider-agnostic by design. With Resend and Stripe connected today, newsletter automation is the next connection on the roadmap.
