Rest API to create issue with epic link

[Juan Leon]

Hi, I am trying to create a ticket and include the epic_link (customefield_1003) but I am getting error "cf_10003 cannot be set. it is not on the appropiate screen"

Any suggestions as to how can I achieve this or what I am doing wrong. 

I am using Jira v8.5.17

Thank you

Your REST call looks correct to me, so I'd want to do some debugging on the message it's coming back with.  Two tests:

1.  Can you create the issue over REST without the Epic link field?  (i.e. same code, but don't put in the line that sets cf_10003)

2.  Can you manually create the issue, as the user making the REST call, in the UI, filling in the Epic link with myproject-766?

@Nic Brough -Adaptavist-  sorry for the late reply.  for question 1, yes I can create a ticket excluding the epic link parameter.

for question #2, I am not familiar with making the REST call in the UI. can you give me an example on how will this be done. 

thanks

Hi @Juan Leon 

Welcome to community!

Can you confirm that the field customfield_10003 is available in create screen of the project and issue type?

Are you able to do the same operation from the UI successfully?

Hi @Fazila Ashraf  

Thank you for your reply, yes the 'Epik Link' (cf_10003) is available,

[Juan Leon]

Update: It turned out that I used the wrong customfield number. it was cf_10001 instead of cf_10003.  thanks for your help.

How do you know that cf_id number is 10001

[Nic Brough -Adaptavist-]

Because you look at the custom field ID?
