How to add some information to description (Jira REST API)

[Darik ____]

Hello, how to add some information to description of the issue without removal any data?

I am able only to update a description  but I need to add more information to original text.

I use postman and Jira(v8.4.2)

{
"update": {
"description": [
{
"set": "Need to add more information "
}
]
}
}

Thank you.

Hi @Darik ____ 

The way that I do that is to run a GET call on the issue, extract the Description, edit or append what I want to get the full new Description, then do the Update as you've shown above

Could you provide me with an example please?

So initially I do this call

/rest/api/2/search?jql=key=ABC-123&fields=key,summary,description

which returns minimal info, but allows me to get the current Description (held in a string variable).

I then change the text of the variable to what I want it to be and then use a PUT call with

/rest/api/2/issue/ABC-123

passing in the Description much like you show in your question
