Best Practices for Non-Technical Users
To get the most out of the httpSMS + Relevance AI integration without writing code:
- Configure authentication properly: Ensure OAuth credentials are correctly set up and permissions are granted.
- Use proper request formatting: Structure API calls with correct headers and body parameters for SMS sending.
- Implement error handling: Monitor response status codes and implement retry logic for failed messages.
- Optimize message content: Keep SMS messages concise and within character limits to avoid splitting.
- Respect rate limits: Space out bulk SMS sends to comply with API throughput restrictions.
