Using Keystile, in SimplyPrint: add file to queue (Add an existing file (API-uploaded or user-file) to the print queue. For uploading a new file at the same time, use "Upload File & Add to Queue").What it can do (63 actions)
| Action | What it does | Changes data |
|---|---|---|
| Add File to Queue | Add an existing file (API-uploaded or user-file) to the print queue. For uploading a new file at the same time, use "Upload File & Add to Queue". | |
| Adjust Filament Weight | Update the remaining filament on a spool. Provide ONE of "grams remaining" / "percent remaining" / "weighed gross" — the other two derive from it. | |
| Approve Queue Item | Approve one or more pending queue items. | |
| Archive Print Jobs | Archive one or more completed print jobs (removes them from the active history view). | |
| Assign Custom Tag | Attach an existing custom tag to a printer, printer group, file, or queue item. Use "Create or Update Tag" first to get the tag ID. | |
| Assign Filament to Printer | Assign a filament spool to a printer at a specific nozzle + extruder slot. Defaults to nozzle 0 / extruder 0 (single-nozzle single-extruder printers); set the indices for multi-nozzle (e.g. IDEX, toolchanger) or multi-material (MMS, MMU) printers. | |
| Cancel Pending Print | Cancel a print that's queued/staged on a printer but hasn't started yet (status = print_pending). Distinct from "Cancel Print", which targets the active print. | |
| Cancel Print | Cancel the current print on a printer. This is destructive — the job cannot be resumed. | |
| Clear Printer Bed | Mark a printer's bed as cleared after a print finishes. Bread-and-butter step in AutoPrint flows — pair with a "print done" trigger to automate bed clearing. | |
| Create Filament | Add a new filament spool to your inventory. Use the free-text brand/color fields for ad-hoc spools or the catalog ids for known SKUs. | |
| Create or Update Folder | Create a new folder in the user file system, or update an existing one (pass the folder ID to edit). Optionally an "organization" / shared folder with per-rank view/upload/modify permissions. | |
| Create or Update Tag | Create a new custom tag, or rename / re-style an existing one (pass the tag ID to edit). | |
| Custom API Call | Call any SimplyPrint REST endpoint the piece does not wrap directly. Useful for admin / partner / school-dashboard endpoints and anything else behind OAuth scopes. | |
| Delete Files | Permanently delete one or more user files by UID. Returns a partial-success report — files the caller can't modify are reported in `errors` while accessible files are deleted. | |
| Delete Folders | Delete one or more folders (and everything in them). All-or-nothing: if any folder isn't modifiable by the caller, the whole call fails. | |
| Delete Queue Group | Delete a queue group. Items in the group are moved to "Move to" group, or to the first remaining group if not specified, or set to ungrouped if it was the last group. | |
| Delete Tag | Delete a custom tag from the account. The tag is removed from every printer/file/queue item it was attached to. | |
| Deny Queue Item | Deny a pending queue item (remove or send back for revision). | |
| Detach Tag | Remove a single custom tag from one printer, printer group, file, or queue item. | |
| Download File | Download a file from SimplyPrint by user-file UID, queue-item ID, or print-job UID. Returns the file as an Keystile file reference plus content-type / size metadata. | |
| Empty Queue | Delete every item from the print queue (optionally filtered to a group or done-only). Destructive. | |
| Get Account Statistics | Fetch high-level printing statistics (total prints, materials used, hours, etc.). | |
| Get Current User | Return information about the SimplyPrint account connected to this flow. | |
| Get Farm Overview | One-shot fleet summary: total printer count plus per-bucket lists (online/offline, printing/paused, awaiting bed clear, in maintenance, requires-attention, AI failure detections, …). Use this instead of paginating "List Printers" when you just need counts and the printers in each state. | |
| Get Filament | Get detailed information about a specific filament spool by numeric ID or 4-character short ID (uid). | |
| Get Filament History | Paginated usage history for a specific spool — print jobs, weight adjustments, drying cycles, etc. | |
| Get Next Queue Items | Resolve the next-up queue items for one or more printers using the company's match criteria (with deduplication so the same item is never assigned twice). Returns the matched queue object with item references per printer. | |
| Get Print Job | Fetch a single print job's full record by its UID — timeline, pictures, spools used, gcode analysis, filament data, cost, AI inference, custom fields, etc. | |
| Get Printer | Get detailed information about a specific printer. | |
| Get Printer Notifications | Fetch the open notifications/events on one or more printers. Pairs well with the `requires_attention` bucket from "Get Farm Overview". | |
| Get Queue Item | Fetch a single queue item by numeric ID — returns the formatted record (file metadata, assignments, custom fields, …). | |
| List Custom Fields | List all custom field definitions on your account. | |
| List Filaments | List filament spools in your SimplyPrint account, with optional filters and sort. | |
| List Files | List files in your SimplyPrint account, optionally within a folder and/or filtered by a search term. | |
| List Pending Queue Items | List queue items awaiting approval, denied, or sent back for revision. | |
| List Print History | List completed print jobs, optionally filtered to a single printer. | |
| List Printers | List every printer in your SimplyPrint account with current status. | |
| List Queue Groups | List every queue group on your account. | |
| List Queue Items | List items in the print queue, optionally filtered to a single queue group. | |
| List Tags | List all custom tags configured on your account. | |
| Mark Filament as Dried | Record that one or more spools were just dried. Updates each spool's last-dried timestamp. | |
| Move File | Move one or more user files to a different folder. | |
| Move Queue Item | Move a queue item to a different queue group. | |
| Pause Print | Pause the current print on a printer. | |
| Preview Next Queue Items per Printer | Read-only preview of the next-up queue item for each given printer (no dedup, no offline checks). For each printer, returns either the matched queue item or the issues blocking a match. Different from "Get Next Queue Items": that one dedupes for actual scheduling, this one shows what each printer would pick. | |
| Remove Queue Item | Remove an item from the print queue. Destructive — the item is gone. | |
| Resolve Printer Notification | Mark a printer notification as resolved (or dismissed). For notifications with multiple actions, pass `action` to pick one or `force: true` to resolve without choosing. | |
| Resume Print | Resume a paused print on a printer. | |
| Revive Queue Item | Bring a completed (done) queue item back to the active queue. | |
| Save Queue Group | Create or update a queue group. Pass an existing group ID to edit it; omit it to create a new one. Requires the Queue Groups feature on the account. | |
| Send G-code | Send raw G-code commands to an operational printer (requires Print Farm plan). | |
| Set Custom Field Values | Set custom field values on one or more entities (queue items, files, printers, etc.). | |
| Set Printer Out of Order | Mark one or more printers as out-of-order (or clear that flag). Requires the Out-of-Order feature on the account. | |
| Set Queue Item Printer Assignments | Assign one or more queue items to specific printers, printer models, and/or printer groups. Replaces the current assignments on each item. | |
| Skip Print Objects | Skip one or more individual model objects on the current print (printer must be in PRINTING / PAUSED / PAUSING / CANCELLING / RESUMING state). Single printer per call. | |
| Start Print | Start a print job on one or more printers from an existing file, queue item, or print-job reference. | |
| Unarchive Print Jobs | Restore one or more archived print jobs to the active history view. | |
| Unassign Filament | Detach a specific filament spool from whichever printer it is currently assigned to. | |
| Update File | Rename a user file and / or update its compatible-printer assignments. (Thumbnail upload is not exposed here — multipart isn't supported on this endpoint over OAuth via the AP HTTP client.) | |
| Update Queue Item | Update a queue item (amount, note, etc.). | |
| Upload File | Upload a file or HTTPS URL to SimplyPrint. URL uploads stream with ~95 MiB peak RAM; File uploads are buffered by AP. Files over 95 MiB are chunked automatically. Returns the API file id — pass it to "Add File to Queue" or "Start Print" later. | |
| Upload File & Add to Queue | Upload a local file or HTTPS URL to SimplyPrint and add it to the print queue in one step. URL uploads stream with ~95 MiB peak RAM; File uploads are buffered by AP. Files over 95 MiB are chunked automatically. For starting the print afterwards, chain a "Start Print" action. | |
| Upload File to Folder | Upload a file (or HTTPS URL) and save it to your SimplyPrint user file system, optionally inside a specific folder. URL uploads stream with ~95 MiB peak RAM; File uploads are buffered by AP. Files over 95 MiB are chunked automatically. |
