curl call with parameters into variable doesn't work

Question

I'm working with installr API. I'm trying to do the following curl request via a script :

curl -H "X-InstallrAppToken: mytoken"  https://www.installrapp.com/apps.json/ \
  -F 'qqfile=@'$APKPATH \
  -F 'releaseNotes=These are my release notes' \
  -F 'notify=true'

and it works perfectly. However, when I try to get my release notes from a file with a variable like this :

RELEASENOTES=`cat "release_notes/test.md"`
curl -H "X-InstallrAppToken: mytoken"  https://www.installrapp.com/apps.json/ \
  -F 'qqfile=@'$APKPATH \
  -F 'releaseNotes='$RELEASENOTES \
  -F 'notify=true' > /dev/null

it doesn't work at all, only the first word is sent. For the others, I have the error Could not resolve host: xxx.

I did a echo on these two curl request and the exact same thing is printed. is that the catcommand which return a specific format ?

Probably an issue with the quotes and spaces. You can use double-quotes around a variable to allow variable expansion in the shell.

RELEASENOTES=$(cat "release_notes/test.md")
curl -H "X-InstallrAppToken: mytoken"  https://www.installrapp.com/apps.json/ \
  -F "qqfile=@${APKPATH}" \
  -F "releaseNotes=${RELEASENOTES}" \
  -F 'notify=true' > /dev/null
