Question:
Keyword I had registered disappeared and had to register again today. Please help.
Answer:
It may have been overridden when you save the flow. The best way to create a Trigger is by using the Flow Builder and add Trigger keywords.
There are 2 ways to create a keyword trigger
Using the Flow builder
Using the Bot Tools → Keywords
Every time you save a Flow with keyword triggers, its keywords are automatically registered on the Bot Tools → Keywords
Please take note that when you create a keyword using the Bot Tools → Keywords, and then save the Messenger Bot Flow that does not have a Keyword Trigger → then it will automatically remove the keywords on your Bot Tools → Keywords
