Not able to create or get and jira issue using Api rest

[Isabel Bueno]

I'm trying to use the rest api in jira cloud, but when I try to get an issue I got the following error "Issue does not exist or you do not have permission to see it.", if I try to create a new issue I got the following error "You do not have permission to create issues in this project.". But If I connect to jira I could see any issue and i could  created it too.

I'm using token authentication with the OAuth 1.0 method.

Can anyone tell me what these errors are due to? Thanks

Hi @Isabel Bueno Welcome to the community!

Please create API token and use that.

Also, check if you have sufficient permission on the particular project to create an Issue.
