Adding a webhook to an existing flow that triggers from messenger catchall

(Roger Swannell) #1

Hi,

I have an existing flow that uses the Welcome & Help template and so is triggered by a catchall in messenger. I want to trigger the flow via a Facebook ad and so need to add a webhook. Is it possible to add a webhook to an existing flow? If not, is there an easy way to copy the contents of the existing flow into a blank flow that is triggered by webhook?

Thanks

Hi Roger,

To change the trigger of a flow you just need to turn the flow off and then you can delete the trigger and add a new one.
Please be aware though that if your flow starts as a webhook trigger you won’t have any response path in order to send a message to your users.

Have you taken a look at our Facebook Ads JSON Web Tool as an option for how to trigger a flow from a Facebook ad?

Thanks, I didn’t know about the Facebook Ads JSON Tool. If I use that, would I need to make any changes to the existing flow?

And, does not having a response path and not being able to send a message to the user mean that the bot wouldn’t work?

Hi @Roger_Swannell1

A message to a user will always require a valid response path.

Hi @Roger_Swannell1

With regards to the existing flow you’ll probably need to update the trigger to be a keyword trigger so you can choose a word to trigger when setting up the JSON Ad’s.
