— For developers

Ship in an afternoon

One REST API for SMS, OTP, WhatsApp and voice — real quickstarts in five languages, delivery webhooks, and DLT handled in the request. No SDK to learn before your first message. Test against the same endpoints with a test key, then switch to live once your DLT header is approved.

Launch campaigns without code

Bulk SMS, WhatsApp broadcasts, and voice campaigns with DLT and NDNC handled for you. Talk to a team that sets up the sender, the templates, and the routing — you run the campaign. Pricing is per message with GST shown separately, so the number you see is the number you pay.

Every channel your customers use

Reach the app a developer ships, the broadcast a marketer runs, and the voice line a support team answers — from one account, billed together and compliant together, without juggling a separate vendor for each channel.

— Compliance

DLT, TRAI, and NDNC — handled

Indian messaging is regulated, and we treat that as part of the product. Your principal entity ID and DLT template are validated on every SMS; voice campaigns are scrubbed against the National Do Not Call registry; consent and opt-out are recorded per message. You send; the compliance is already in place.

Send your first message in five minutes

Plain JSON over HTTPS, a bearer token, and the two DLT identifiers India requires. The response returns a message ID you reconcile against a delivery receipt on your webhook. Quickstarts in cURL, Node.js, PHP, Python and Java.
