Here we should think about the future. If you plan changing your automation scenario regularly, and you want to have a user-friendly interface, then it's better to use NoCode solutions. Such as Zapier or Integromat.
For example, you have an email sending scenario. After a while, you decide to change improve your texts in it. You can do this yourself through Zapier/Integromat.
However, if changes are not planned or are planned extremely rarely, it makes sense to consider the option of writing code that will automatically perform the same functions.
In this case, we move all important variables into a separate block and provide you with editing instructions. Therefore, it will be possible to make changes at any time.
It should be added that you significantly save on a monthly subscription, as it is not required for the code to work.
