Send SMS Messages

Kudosity supports two ways to send SMS depending on the use case:

• Single recipient → V2 API (simpler, JSON-based)
• List-based send / multiple recipients → V1 API (supports list_id and comma-separated numbers)

Authentication

V2 API (single recipient):

• Header: x-api-key: {KUDOSITY_API_KEY}

V1 API (list-based or multi-recipient):

• Header: Authorization: Basic {base64(KUDOSITY_API_KEY:KUDOSITY_API_SECRET)}

Credentials come from the Kudosity dashboard under Developers → API Settings. Set KUDOSITY_API_KEY (and KUDOSITY_API_SECRET, which the V1 API needs) in the environment before calling.

Option A: Send to a Single Recipient (V2 API)
