Workflow Runs

introduction a run represents a workflow run you can easily create new runs, cancel any active run and retrieve a run details from the /runs resource create a run to create a run make an authenticated post request to /runs body json payload parameter required type description workflow yes json a comfy api workflow json name no string optional workflow run name if none provided the run name will be set to the default name api run yyyy mm dd hh\ mm\ ss example request curl curl x post https //api floyo ai/runs \\ h "authorization bearer \<your api key>" \\ h "accept application/json" \ \ json '{ "name" "floyo api demo run", "workflow" { workflow api json } }' example responses status 200 workflow run requested successfully { "id" "run vtgqfqzfotmivzrp", "object" "run", "name" "floyo api demo run" } if the request results in a 4xx or 5xx error, see the error responses docid\ w37qhjsl3ldxxz dyszd section cancel a run to cancel an active run you must make an authenticated post request to /runs/\ runid/cancel a run can be cancelled only if its current status is either in queued or processing example request curl curl x post https //api floyo ai/runs/\<run id>/cancel \ h "authorization bearer \<your api key>" \ h "accept application/json"` example response status 200 run successfully cancelled { "id" "run c7d3esgnvhj1a6ts", "object" "run", "message" "run cancelled" } status 409 run was cancelled, has finished or failed { "id" "run c7d3esgnvhj1a6ts", "status" "cancelled", "object" "run", "error" "run is already finished", "message" "run was cancelled by the user" } status 404 run not found { "error" "run not found" } retrieve a run retrieve a run to get it's current status completed workflow runs will include flotime and partner (3rd party) api nodes usage information to retrieve a run make an authenticated get request to /runs/\ runid query parameters parameter required value default description example expand no outputs presigned url n/a expand a the run response by

the floyo api returns a structured error object alongside the run payload this object is present in two places get /runs/\ runid — when the run has finished with status of failed (including runs that failed due to insufficient credits) post /runs — when run creation is rejected immediately because of insufficient credits or workflow validation errors each error message follows this shape { "type" "insufficient balance", "code" "insufficient flotime credits", "message" "the workflow could not be executed because your team has insufficient flotime credits contact your team admin to add more ", "details" { } } error object attributes attribute type description type string high level error category one of insufficient balance , validation , runtime , or system code string specific error code for the given type use this field for programmatic handling message string human readable description of what went wrong details object optional error specific context (e g missing files, node errors, restricted models) omitted when there is nothing extra to report error types the type field is the primary signal for how to handle a failure type meaning credits insufficient balance the run could not start or complete because your team ran out of credits the code field specifies whether flotime or partner nodes credits are depleted no credits are consumed — the run is blocked before execution can begin validation the workflow failed during the validation step, before execution actually starts (blocked models, missing files, invalid node configuration, etc ) no credits are consumed or debited validation errors happen prior to gpu execution, so no flotime or partner nodes usage is charged runtime the workflow started executing on gpu but a node raised an exception during processing credits may be consumed flotime (and any partner nodes usage up to that point) is charged for the time spent executing until the error occurred system an internal or unclassified error occurred treat as unexpected; the message is a safe, generic description depends on when the failure occurred — if execution had started, partial usage may apply error codes reference insufficient balance code description insufficient flotime credits your team does not have enough flotime credits to execute the workflow insufficient partner nodes credits your team does not have enough partner nodes credits to execute the workflow validation code description details (when present) model blocked the workflow references models that are blocked for your team restricted models , node errors invalid prompt files one or more files referenced in the prompt were not found in storage missing files missing node type the workflow uses a custom node type that is not available on floyo node specific info from the validation layer prompt outputs failed validation one or more output nodes failed validation (e g invalid seed or parameter values) node errors prompt no outputs the workflow has no output nodes defined — invalid workflow a general workflow validation error that does not match a more specific code node errors (when available) runtime code description details (when present) node error a node raised an exception while the workflow was executing node type system code description internal error an internal error occurred while processing the run system error an unknown or unhandled error occurred example responses for failed runs the examples below show the error object in context other run fields ( id , name , requested at , etc ) are included where helpful status 200 run failed —
