Security & Reliability
The Slybroadcast integration with Relevance AI enables seamless automated voicemail campaign management through a robust API interface. This integration allows you to programmatically send voicemails directly to mobile phone mailboxes using Slybroadcast's patented delivery technology while leveraging Relevance AI's workflow automation capabilities.
With this integration, you can easily deploy voicemail campaigns, manage bulk recipients, and schedule deliveries—all while ensuring secure OAuth-based authentication for your operations.
To get started, ensure you have the necessary accounts and system requirements in place, including a Slybroadcast account with API access and valid OAuth credentials. The integration supports multiple audio formats (WAV, MP3, M4a) and provides a straightforward setup process for OAuth authentication and base URL configuration.
Once configured, you can quickly launch campaigns using audio URLs or existing audio files, and make custom API calls as needed. The integration also includes a troubleshooting guide to help you resolve common issues such as authentication errors, audio file format problems, and recipient format issues.
For best practices, implement rate limiting, error handling, and campaign validation to ensure your workflows run smoothly. Additional resources, including Slybroadcast API documentation and OAuth configuration guides, are available for further assistance.

To get the most out of the Slybroadcast + Relevance AI integration without writing code:
- Start with a clear audio file library: Use descriptive file names and ensure all audio files are in supported formats (WAV, MP3, M4a).
- Utilize scheduled campaigns: Plan your voicemail campaigns in advance to optimize delivery times and audience engagement.
- Verify recipient lists: Ensure phone numbers are correctly formatted with country codes to avoid delivery issues.
- Test with small groups: Launch campaigns with a limited number of recipients first to identify any potential issues.
- Monitor API usage: Keep an eye on rate limits and implement delays between API calls to prevent throttling.
