Building the Flow

You must be very familiar with the flow builder, because it is just like the NicoChat flow builder!

There is no send message step, question step or send email step in NicoApp subflows. If you need help using the flow builder, check the previous tutorials:

For some special action types, available only in NicoApp version 2.0, see below:

Trigger Event

See how to use the trigger in the Trigger Event section.

Get a Single Use URL

See how to use the Single Use URL in One-Time Use URLs.

Return Error on Action

This action type is used to make a NicoApp action fail. When users provide the action inputs and call your app's actions, you can use "Return Error on Action" to let them know what went wrong in the app and what can be improved to fix the problem.

The "Error Message" you provide here will be sent to the channel's Error Log.
Since the error message has a length limit, you can also assign error codes to identify the most frequent errors.
