    Depending on the implementation and network conditions, using an external API may introduce additional latency, which could affect the performance of real-time applications.
  • Security Concerns
    Sending data over third-party APIs might raise security issues, particularly for sensitive information, as it involves trusting the provider with data management practices.
  • Learning Curve
    While designed to be user-friendly, new users might face a learning curve in navigating the platform and fully understanding the capabilities and limitations of the available APIs.
  • Limited Customization
    The APIs provided may not fully meet the unique proprietary needs of some businesses, requiring additional development for customization that might not be possible directly through the platform.
