curl - Nested quotation marks in "do shell script"-command cause error -

i'm running curl shell script (indesign) extendscript jsx-file.

this works simple queries, in command below can see i'm having quite quotation nesting, seem making command fail! it's not throwing errors, wordpress-post not being changed!

var command = 'do shell script "curl -x put -h \'content-type: application/json\' -d \' { \'title\': \'blub\', \'content_raw\': \'updated post content\' } \' -u username:password http://website.com/wp-json/wp/v2/cpt/12/"'; var response = app.doscript(command, scriptlanguage.applescript_language); 

when write throws error, because of false quotations:

var command = 'do shell script "curl -x put -h \"content-type: application/json\" -d \" { \"title\": \"blub\", \"content_raw\": \"updated post content\" } \" -u admin:password http://seebook.dev/wp-json/wp/v2/calendar/12/"'; 

when run command directly in terminal, works...

curl -x put -h "content-type: application/json" -d " { \"title\": \"updates title\", \"content_raw\": \"updated post content\" } " -u username:password http://website.com/wp-json/wp/v2/cpt/12/ 

so version:

var command = 'do shell script "curl -x put -h \"content-type: application/json\" -d \" { \'title\': \'blub\', \'content_raw\': \'updated post content\' } \" -u username:password http://website.com/wp-json/wp/v2/cpt/12/"'; 

how can write query, works?

i guess that's quite noob question, i've never had such situation before...

all best, lukas

try this, outer quotes must double quotes, content-type part enclosed in single quotes , query created quoted form of expression

set query "{ \"title\": \"updates title\", \"content_raw\": \"updated post content\" }" shell script "curl -x put -h 'content-type: application/json' -d " & quoted form of query & " -u username:password http://website.com/wp-json/wp/v2/cpt/12/"
