Authentication

\n

Most endpoints require an Authorization header. Two schemes are accepted:

\n\n

Set the collection variables smswebsite (defaults to the production host) and apikey (your account API key), then all requests inherit auth automatically. The Authentication and Webhooks folders are public and send no auth header.

\n

Pricing

\n

Sends deduct from purchased bundles first, then wallet balance at GHS 0.05 per SMS part (160 GSM-7 chars per part; 153 for concatenated parts).
