Yes, I'm doing it likes this:

The result in my self-hosted healthcheck.io is the following:

{"text":"\nBackrest Snapshot Notification\nTask: backup for plan \"main\" at 2024-11-05T20:00:02+01:00\nEvent: snapshot success\nSnapshot: 182cfa8d3e197f05acf1f6b9b772f6a4f0e8649d6fc2801478a78390a6841547\nOverview:\n- Data added: 1.001 MB\n- Total files processed: 547\n- Total bytes processed: 11.011 MB\n\nBackup Statistics:\n- Files new: 1\n- Files changed: 5\n- Files unmodified: 541\n- Dirs new: 0\n- Dirs changed: 7\n- Dirs unmodified: 171\n- Data blobs: 6\n- Tree blobs: 8\n- Total duration: 0.85105408s\n\n"}

Currently, when the ping is sent, the content-type is set to ‘application/json’ whereas I am asking if it is possible to have it in ‘text/plain’ as well.
