iosCustomFields (application parameters) from JSSP

[SorenDP]

Hi Community! 

I am working on a use-case that allows external system to integrate to our Campaign instance in order to create push deliveries and schedule + execute them. Here I have a requirement where I need to be able to set a single application variable "path". However, I have been unable to succeed with that. I mostly get a silent error/exception - So the system does not output any errors. The only thing I can confirm is, that it is related to attempting to set this specific field in my code. If I remove it, everything works again (but without the application variable) 

Code snippet that is not working: 

  var deliveryDoc = nms.delivery.CreateFromModel(templateName, targetDef);
  var delivery = nms.delivery.create(deliveryDoc);

  delivery.label = label;
  delivery.content.iosTitle.source = payload.title;
  delivery.content.iosMessage.source = payload.body;
  delivery.scheduling.delayed = schedule.delayed;
  delivery.scheduling.contactDate = schedule.date;
  delivery.scheduling.validationMode = "auto";
  delivery.validation.useBudgetValidation = false;
  delivery.validation.useContentValidation = false;
    
  var customFieldsXML = '<source><customFieldsItem key="path" value="' + payload.link + '"/></source>';
  var doc = DOMDocument.fromXMLString(customFieldsXML);
  delivery.content.iosCustomFields = doc.documentElement;
  delivery.content.androidCustomFields = doc.documentElement;

  delivery.save();

 
I also tried: 

var doc = new DOMDocument("customFields");

var source = doc.createElement("source");

var customField = doc.createElement("customFieldsItem");
customField.setAttribute("key", "path");
customField.setAttribute("value", payload.link);

source.appendChild(customField);

doc.appendChild(source);

delivery.content.iosCustomFields = doc.documentElement;
delivery.content.androidCustomFields = doc.documentElement;

Which gives me the error: "SCR-160048 Error while processing XML, please check the parameters.". 

I hope someone is able to assist with this challenge or point me in the correct direction allowing me to configure an application custom variable from a JSSP application while dynamically creating a push delivery.

Hi @SorenDP ,

Technically, what you're trying to achieve is possible. I actually developed a similar solution around 5–6 years ago, where I built an entire delivery using JavaScript.

However, the Adobe team rejected that approach. They confirmed it's not best practice and not future-proof.

Now I understand why — every time you upgrade the build, deploy a package, or do any major update, the custom JS-based solution is prone to breaking.

I would suggest a more stable and scalable approach:

• Use a workflow.

• Retrieve the data from the external system via POST or HTTP signal.

• Pass the data into the workflow, select your target audience there, and populate the values with variable in delivery like label etc. you're currently trying to set in the delivery.

• Use a recurring or continuous delivery to send the message.

This method is supported, maintainable, and much less fragile over time.

If you still want to use JSSP, I believe you can pass all the data from the JSSP into the workflow as well.

Hope this helps!

Kind regards,
Parvesh

Hi @Parvesh_Parmar.  Thanks for the feedback. I see how this may not be a sustainable solution. I have switched to working with triggering a workflow from JSSP instead and then parsing variables throughout the workflow to both query the correct recipients as well as setting delivery variables during execution. This seems to be a working solution, however, it is not performing quite as well, but it is solving the use-case. 

Thanks!
