Can we update custom field dynamically by using REST API

Question

Hi Folks,

I am trying to update selectlist custom field dynamically by using REST API and getting input data from REST API and passing that data by using variable but while running the curl getting below error and we are using v2 REST API method.

command : curl -D- -u "Test@abc.com":"jiraadmin123" -X POST --data {"fields": {"customfield_16600": {"value":"$name"}, {"id":"null"}}} -H "Content-Type: application/json" https://abc.test.com/rest/api/2/issue/

Error : {"errorMessages":["Unexpected character ('f' (code 102)): was expecting double-quote to start field name
 at [Source: org.apache.catalina.connector.CoyoteInputStream@1c271e0a; line: 1, column: 3]"]}

Could you please check and let me know if any solution for this task.

Thank you, yes am trying with option id but not able to update field values able to create issues and update summary,

Here observed it's allowing to update existing values only if i tried with new entry getting unexpected value and not able to find out the option id.

--data {"fields": {"project":{"id": "18500"}, "customfield_16600": {"id":"19302", "value": "$name1"}}}

FYI..trying to publish dynamically with $name1.

Could you please check and let me know if any solution for this task.

--data '{"fields": {"project":{"id": "18500"}, "customfield_16600": {"id":"19302", "value": "$name1"}}}'

Do you see the single quote before the curly bracket, you're suppose to have that.

Thank you, tried without quotes but getting below error and not able to process the data without quotes.

--data {"fields": {"project":{"id": "18500"}, "customfield_16600": {"id":"19302", "value": "$name1"}}}

Error :-

{"errorMessages":["Unexpected character ('f' (code 102)): was expecting double-quote to start field name
 at [Source: org.apache.catalina.connector.CoyoteInputStream@57991445; line: 1, column: 3]"]}

Please let me know if i missed any required parameter for data.
