For developers

An API you can integrate before lunch

Predictable REST, honest error codes, and delivery webhooks that actually fire. Authenticate with a bearer token and send your first message in a single request.

REST & JSON: Plain HTTP, no proprietary SDK required
Delivery webhooks: Signed callbacks for every status change
Sandbox testing: Test the full flow before you spend a credit
Idempotent sends: Safe retries that never double-charge or double-send

No engineer required

Your marketing and operations teams run the whole thing from the dashboard. Upload your recipients, organise them into groups, pick a channel, and send. Nothing to deploy.

Recipient groups: Organise recipients into reusable groups by segment, region, or customer type
Excel & CSV upload: Download a ready-made template, fill it in, and import thousands of recipients at once
Send to any channel: Choose SMS or WhatsApp for the same group without rebuilding your audience
Live delivery reports: See exactly what was delivered, what failed, and why, message by message
