Is there any way to add an attachment to an issue by using rest api.

If not rest API please suggest any other methods to upload attachments to an issue from outside of JIRA

[Sam Hall]

Yes - POST /rest/api/2/issue/{issueIdOrKey}/attachments

See docs here: https://docs.atlassian.com/jira/REST/server/#api/2/issue/{issueIdOrKey}/attachments-addAttachment
