Charter OS runs on your accounts — your charter payments land in your Stripe, emails send from your domain, texts from your number. Paste your keys to connect.

Stripe

Connected

Take deposits and balance payments into your own Stripe account.

Resend (email)

Connected

Send branded customer emails from your own verified domain.

Telnyx (SMS number)

Pending

Connect your Telnyx API key + sending number for texting.

A2P 10DLC SMS registration

Pending

US carriers require every business to register its own A2P brand + campaign before sending customer texts — this is the law, not a Charter OS limit. Until yours is approved (typically 1–3 weeks), Charter OS runs email-first and automatically switches SMS on the moment it clears.

SMS is a Fleet-plan feature — upgrade to enable

Keys are stored encrypted per workspace and never shown again. In demo mode, connecting just flips status so you can see the flow.
