Create Contact Lists & Add Contacts

You can create contact lists and add contacts using the Kudosity V1 API.

Authentication

All list operations use V1 Basic Auth:

• Header: Authorization: Basic {credentials}
• Credentials: base64 encode {KUDOSITY_API_KEY}:{KUDOSITY_API_SECRET}
• The user must have KUDOSITY_API_KEY and KUDOSITY_API_SECRET environment variables set
• If the user hasn't configured credentials, refer them to the "If credentials are missing" block in .github/copilot-instructions.md.

API Details

• Base URL: https://api.transmitsms.com
• Content-Type: application/x-www-form-urlencoded
• All requests use curl commands with Basic Auth. Requires VS Code Copilot Agent Mode.
