I'm currently setting up a incoming webhook through Automation on which an external system will POST some data to create/update issues.
One of the actions however is adding an attachment.
Automation currently does not support adding attachment in any way so I'll need to look towards sending a web request from Automation to add it.
Unfortunately (https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-attachments/#api-rest-api-3-issue-issueidorkey-attachments-post) does not allow a base64 encoded string to be passed as a parameter but expects a multipart/form.
Does anybody have some creative ideas/workarounds to capture the base64 encoded attachment and add it to an issue trough automation?
