Old-app API limits

What old-app clients can’t do through HolyArrs, and the fix for each common error.

Supported apps

Seerr, Overseerr, Bazarr, Unpackerr, Prowlarr and the Homepage Sonarr widget. Recyclarr, Maintainerr, Cleanuparr and other apps that talk to Sonarr or Radarr are not supported.

If it does not work

Symptom	Cause	Fix
Every call answers 404	The feature is off, or the address is wrong	Switch on Answer Seerr and Overseerr in Settings > API. Copy the address from the card, URL base included.
401	Key wrong or replaced	Make a new key and paste it into the app.
403	The key’s owner is turned off or can’t manage the Library. Prowlarr also needs permission to change settings.	Make a new key as someone with both permissions.
A hak_ key is refused	HolyArrs API keys don’t work here	Use the keys from the Requests from Seerr and Overseerr card.
Files stay after removing in Seerr	Let these apps delete files is off	Turn it on if you want removal to delete.
A Source you deleted by hand comes back wrong in Prowlarr	Prowlarr still knows the old one	Run Sync App Indexers in Prowlarr.
Bazarr logs connection errors	HolyArrs has no live feed	Turn Bazarr’s live feed off. Its scheduled sync still works.

For experts

What these apps can't do

Area	Behaviour
Versions	Apps see one copy per title, the main Version. A 4K Version beside it is invisible.
Library folder	Choosing another folder for a title is ignored. Move titles in HolyArrs.
Quality	Choosing other pick rules switches the main Version’s pick rules, which can start a search for a better copy.
Show type	Changing the series type of a show already in the Library is ignored.
Settings calls	Pick rules, naming, notifications and backups are not answered. Indexers are answered only the way Prowlarr writes them, one at a time.
Unanswered calls	Return an error. HolyArrs never pretends a call worked.
Tags	Not attached to titles, so lists filtered by tag are not narrowed.
Languages	Carry only their name. No known original language reads “Unknown”.
Version number	Status reports 4.0.99.0 on the Sonarr side and 5.0.99.0 on the Radarr side, because clients choose their calls from it.
