Passing Intent Parameters to a form?

[Kevin MacDermid]

Hey, this might be in the docs but I couldn't figure it out. I'm looking at creating a customer service agent and I want the following cases to work.

1. "I would like to cancel an order"

Which goes to a GetOrderInfo page and asks for the order number and email address

2 "I would like to cancel the order 12345678"

Which goes to the GetOrderInfo page and realizes that the order number has already been provided.

I've figured out having the order number get recognized as part of the intent, but I don't see how to tell the GetOrderInfo page to look to see if the parameter already exists. The only way I can see handling it at the moment is with conditional routes to separate versions of the GetOrderInfo page, but that would create a lot of technical debt in maintenance.

If anyone knows how to do this I'd appreciate it. Thanks!

I believe the quick start guide has an example that is very similar to this.

Note:

• The New Order page has an intent route, where the intent training phrases accept optional shirt size parameters.
• The New Order page has a form with the same parameters. 
• A condition route is used to check that all parameters have been provided.

Right on, thank you! I'd tried that but made a mistake and used different names for the parameters in the two locations, so they didn't connect. It's now fixed.

I am a little concerned about how all parameters will effectively be in the global namespace, seems like it could be challenging to keep the parameters under the intent aligned with all the pages that follow from it. This shouldn't cause a problem for my relatively small bot though.
