Unable to create a jira issue in which I want to link to another issue using link type 'Child'

[sarath kumar]

Using JIRA REST API I am unable to create a Jira issue in which I want to link to another issue using link type 'Child' however I am able to create it with other issue link types like 'Tests', 'Related', 'Parent' etc. But all issue link types are available in the application and I am able to create issue with all link types in UI. Kindly help.

API: https://<jiraservername>/rest/api/2/issue

Payload:

{

    "fields": {

        "summary": "Manual Test with Steps and custom fields created using API",

        "project": {

            "key": "TTP"

        },

        "description": "First Manual Test with Steps and custom fields created using API",

        "issuetype": {

            "name": "Test"

        },

        "labels": [

            "Label1",

        ]

    },

    "update": {

        "issuelinks": [

            {

                "add": {

                    "type": {

                        "name": "child"

                    },

                    "outwardIssue": {

                        "key": "TTP-15757"

                    }

                }

            }

        ]

    }

}

Error: 

{

    "errorMessages": [

        "No issue link type with name 'child' found."

    ],

    "errors": {}

}

Hi @sarath kumar 

Try changing outwardIssue to inwardIssue so it could be like this: 

"add": {

                    "type": {

                        "name": "child"

                    },

                    "inwardIssue": {

                        "key": "TTP-15757"

                    }

}

Issue link types can have different descriptions for inward and outward issues, you can check yours in Settings > Issues > Issue linking.

Thank you @Alisa Zamaraeva for taking the time to help me.

Description in Settings> Issues > Issue Linking.

Also, I have tried with inwardIssue but no luck. Please help.

Hi again @sarath kumar 

From what I see on the screenshot, my next guess is that when you create issue link with api you choose link type by name (first column), not outward/inward description. And based on the screenshot you posted, there are no Child issue link type. 

As I understand, when you try this code with Parent link type it makes 1st issue a parent and 2nd a child, but you want it vice versa.

Try this, it should make things right. 

"add": {

                    "type": {

                        "name": "Parent"

                    },

                    "inwardIssue": {

                        "key": "TTP-15757"

                    }

}
