Integrate Contiguity
afternoon
Contiguity's API is simple but powerful. Whether you use our SDKs or REST API, Contiguity fits right into your codebase.
import { Contiguity } from "contiguity"const contiguity = new Contiguity("contiguity_sk_...your_token...")await contiguity.text.send({to: "+1234567890",message: "Hello from Contiguity!"})
Built differently. On purpose.
Carrier Bureaucracy? None.
No A2P 10DLC registrations, several-week long waits, campaigns, or carrier approval processes – with perfect delivery.
Ready for production instantly
When you sign up, you're ready to go. Contiguity's machine learning models continuously assess your account, which means you don't have to go through multi-layered KYC/approval schemes to start sending to real customers.
Built for real traffic
Contiguity's API is robust, failure tolerant, and engineered to handle immense load. Features like automatic retires, fallback, and more ensure your message delivers.
Fees? We don't know them.
Traditional providers charge fees on top of fees, just to send a simple SMS. On Usage tiers, Contiguity charges an industry-low flat rate: $0.005/message. No carrier, international, or any other kind of fees.
Innovation at our core
Contiguity supports channels like WhatsApp and iMessage that are typically plagued by paperwork and strict rules. Send without dealing with the Apple for Business guideline hell, Meta Campaigns corn mazes, or per-message fees.
All the extras, at no extra cost
Contiguity has tons of features baked right in, all at no cost to you. Send SMS OTPs to verify customer phone numbers, or even have users message you instead. Plug and play.
