Marketing activity flow problem

[MihalySzabo]

Hi-

I am trying to create a marketing activity extension for our app, but cannot get it working. I have already made the extension and the server endpoint POST:preload_form_data. When the shop owner clicks "Create campaign", that endpoint is called by Shopify, as expected. My app responds with 200:OK and payload

{
	form_data: {
	}
}

as there is no options that should be populated on the fly. At this point I come to a dead end, as the client throws this error:

while our app does not receive any other request from Shopify to any other endpoints, so I cannot understand what this error refers to as a non-existing page.

Any suggestions what I may missed is highly appreciated.

Kind regards,

Mihaly

Hello. Budget field is a required field to create a campaign. In the preload_form_data you need to return response with the budget_id field (the id is your own created during extension creation). The budget response is required to return currency. By the way, you can just copy an example to return

{
  	"form_data": {
    	"budget": {
      	"amount": 5,
      	"currency": "CAD",
      	"help_text": "Your shop will perform best with a $20 daily budget."
    	}
  	}
}
