How to execute curl command using snaps

Have you taken a look at the Rest Snap Pack?

I am also facing the same issue . Is there any way out to call the curl command from the REST snaps ? I checked the documentation but could not find anything regarding that .

If you want to execute CURL command, you can use Script snap. You have choice to choose between JavaScript/Python/Ruby. Using Python, you can invoke CURL command via SubProcess module. subprocess — Subprocess management — Python 3.10.6 documentation

This type of sample curl comand : "curl -v http://localhost:8093/query/service
-d ‘statement=SELECT text FROM tweets WHERE rating = $1 AND when > $2&args=[ 9.5, “1-1-2014”]’ "

First of all, I hope your service http://localhost:8093/query/service is located within the plex/node where you are executing the pipeline. If not, then its an incorrect use-case. If yes, then there are two ways to do it.

(a) Use REST POST snap. The entire body can be given in Entity property.
(b) Use Script snap with python/javascript and invoke the post call using the respective library.

But, first option is the best and the easiest.

I have used Rest post snap and it is working for me

Does this mean that your document$ ‘$’ is the curl?

What if I want to use this?
curl -f -u “demo:ce544b6ea52a5621fb9d55f8b542d14d” \ -o result.pdf \ -F “url=http://en.wikipedia.org” \ https://api.pdfcrowd.com/convert/20.10/
