Triggers posting to third party URL: Not sending headers

[Lindsay Klatzkin]

My goal is to send JSON formatted data to Mulesoft.

• Created "HTTP Post" trigger
• Created a template which has valid JSON
• Set the Trigger Type properties to JSON
• Confirmed the preview is generating valid JSON
• Trigger the trigger -- mulesoft reads the request headers as "application/x-www-form-urlencoded"

I would have expected that the headers would be sending application/json in the headers with this option selected.  I have tried changing the template's "template type" from "generic" to "http post" and this has not changed.

What do I have to do to get the trigger to send the correct content-type headers?

I don't know mulesoft, but I use the triggers regularly to post out to an external application and the easiest way is to use name-value pairs. It posts them as a form post,  the MIME type is application/x-www-form-urlencoded, and you can pick that up in Mulesoft https://help.mulesoft.com/s/question/0D52T00004mXXkzSAG/xwwwformurlencoded-in-http-request-connector-as-post

Your mileage may vary. I write my own APIs in C# using MVC and post out to them using triggers or smart events, but either way, the name-value pairs is the easiest. You write out which fields you want in the arguments text box as a list like this:

sessionid={!USERPROFILE.SESSIONID!}
endpoint={!API_ENDPOINT!}
useremail={!USERPROFILE.EMAIL!}
authkey={!COMPANY.AUTH_KEY!}
profile=randomstring
entityid={!SODOCUMENT.MEGAENTITYID!}
type=PriceList
implementationorlive=Live
sessionorwslogin=webservices

The above is an example, but in EVERY smart event/trigger I do, I pass at least the first 3, if anything, just for logging purposes. The rest in this example are either custom fields, standard fields or strings I need to pass. In my C# code, I pick these out from the Request.Form in a foreach loop. After that, you do what you want.

foreach (var formVar in Request.Form)

Thanks Lee.  I'm just wondering why Intacct would offer JSON as an option without setting the content-type header to application/json.

[Lee Savidge]

I would imagine it is setting the content type appropriately. If I was curious, I would set up a small web service and call if from the trigger and query the content type just to see, but I would be surprised if it doesn't. That being said, I've never bothered as it is easier to write a key/value pair list than it is to write JSON by hand which is why I always use the name/value pairs.
