Send single SMS (JSON)

Send a single SMS to one or more recipients via JSON request body.

Key Features:

• JSON request/response format
• Optional AES-256 GCM encryption for in-transit security (set X-SSL: 2 header)
• Supports synchronous or asynchronous processing
• DLT/TRAI compliant messaging

Encryption Mode (X-SSL=2):
When encryption is enabled, the entire request body is AES-256 GCM encrypted.
IV and AES key can be provided in headers (X-SSLIV, X-AES-KEY) or fetched from DB using feedid.
The feedid query parameter is required when using encryption.

JSON via query parameter:
Alternatively, the JSON payload can be passed as the json query parameter instead of in the request body.
