Notes and Best Practices

  • When using phone numbers as identifiers, always use the international format (e.g., +12124567890)
  • Remember to URL-encode identifiers, especially email addresses and phone numbers with special characters
  • The ID lookup is generally faster than lookups by email or phone number
  • If you’re unsure whether a contact exists, use this endpoint to check before creating a new contact
  • Consider implementing caching mechanisms for frequently accessed contacts
