# Airtel Smart API (legacy)

**Canonical:** https://apis.io/apis/bharti-airtel/airtel-smart-api/  
**Provider:** Bharti Airtel — https://apis.io/providers/bharti-airtel/  
**Documentation:** https://openapi.airtel.in/smartapi/#/docs

Airtel Smart API (legacy) is one of 5 APIs that [Bharti Airtel](https://apis.io/providers/bharti-airtel/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Carrier Billing, Subscription, Identity Verification, Legacy, and Authentication. The published artifact set on APIs.io includes API documentation and an API reference.

Airtel's original partner developer programme, launched in 2017 and now an unmaintained legacy portal (the site still carries a 2017 copyright). Its public documentation still describes real OAuth 2.0 authorization-code and implicit grant flows and three partner services — carrier-billing charge, subscription activation/deactivation, and an LRN (local routing number) and porting lookup — plus an Aadhaar/UIDAI DigiAuth authentication and e-KYC integration. Production host is not published; documented endpoints use an <IP>:<Port> placeholder and access is granted only after partner registration, so no specification was harvestable.
