What is required to extend Flow for advanced functionalities like SMS and Slack actions?

To extend Flow for advanced functionalities such as SMS and Slack actions, custom code is often required. This is because native Flow capabilities may not inherently support all the specific integrations and interactions that these types of functionalities demand.

Custom code enables developers to create tailored solutions that connect Flow with external services, hence allowing for richer features, such as sending SMS messages or interacting with Slack. This is particularly useful when standard Flow configurations do not meet unique business needs or when deeper integration is necessary to connect to third-party APIs.

Additional user permissions may be necessary for users to access certain advanced features within Flow, but merely having the permissions does not enable the direct functionality. External apps may also provide some functionalities, but custom code is what truly extends Flow to integrate these external services effectively. Lastly, a specific Flow type is not a requirement for adding advanced functionalities like SMS or Slack; rather, it’s the custom code that facilitates these enhancements.
