Version support
You can select between development and production modes using the Use Development Version of the voiceflow project toggle button in the skill configuration.
Development lets you connect to the version displayed on the Voiceflow canvas, production will connect to the version that has been published. Check details on how to update each version here: Overview.
Fallback support
Messages will be flagged as fallback when the intent returned by Voiceflow is None. Fallback messages are necessary for interoperability with other skills.
Two ways of specifying fallback responses with Voiceflow are:

Content Card support
Voiceflow content blocks
Currently we support the following Voiceflow content blocks:
Text
Image
Buttons
Cards
URL Support
Links/URLs are currently supported for text blocks, but not within the descriptions of the card block. If a text block contains a valid URL, it will be stripped out of the spoken text and a clickable link card will be visible with the extracted URL.
Soul Machines content cards
Voiceflow supports all types of Soul Machines Content Cards through the Dev Custom Action block.
The Custom Action block currently requires a Voiceflow subscription.
The name of the Custom Action step must be smcard, and the Action Body is expected to be a JSON object where the text property contains the output text, and the variables property contains the content card variables.
If desired, you can connect a block to the default path in the action step, to continue the conversation from that point; multiple paths are not supported.
