Forwarded to the worker per-prompt and excluded from idempotency comparison. On a deployment it is dispatch-only and never stored; on Comfy Cloud it is persisted with the prompt, because the worker needs it, and redacted on every path that returns a workflow to a caller. | ||

| Send the one credential you hold: an API key as `api_key_comfy_org`, or the session token an interactively signed-in client has instead as `auth_token_comfy_org`. Sending both is accepted and both are forwarded, but it is not a supported combination and which one a node uses is not defined here. Note a session token is short-lived and is not re-minted for you, so one submitted long before it executes may expire in the queue.' |

💡 Result:
<search_synthesis>
In the context of ComfyUI and the Comfy Platform, api_key_comfy_org and auth_token_comfy_org are specific keys used to propagate authentication credentials from the frontend to the backend during workflow execution [1]. These parameters are primarily used when submitting prompts via the API (e.g., the /prompt endpoint) to allow backend nodes to access authorized services, such as paid Partner Nodes [2][3]. Key details regarding these parameters: 1. Purpose: They are embedded within the extra_data field of the queuePrompt REST API payload [1][4]. This mechanism allows backend nodes to receive these tokens as hidden inputs, enabling them to perform authorized upstream requests [1][5]. 2. api_key_comfy_org: This represents a user-generated API key (typically starting with comfyui-) obtained from the Comfy Platform [2][6][7]. It is used for accessing paid Partner Nodes and Comfy Cloud services [7][8]. 3. auth_token_comfy_org: This represents a JWT token associated with a logged-in Comfy Org user [1]. 4. Implementation: Backend nodes can access these values by defining them in their INPUT_TYPES under the hidden dictionary [9][4][5]. For example: python @classmethod def INPUT_TYPES(s): return { "hidden": { "api_key": "API_KEY_COMFY_ORG", "auth_token": "AUTH_TOKEN_COMFY_ORG" } } def execute(self, api_key: str, auth_token: str): # Use the tokens for authorized requests... 5. Security: These keys are considered sensitive. The ComfyUI backend includes them in a SENSITIVE_EXTRA_DATA_KEYS list to manage their handling during execution [5]. Users are advised never to share their API keys or commit them to version control [7]. While the frontend automatically handles the inclusion of these keys when running workflows in the browser, developers calling the API directly must manually include them in the extra_data object of their request payload [3].

Broken Authentication
Reachability: External
Exploitability: Moderate
CWE: CWE-441
Reject or define the dual-credential combination. The schema accepts and forwards both credentials, while the receiver exposes them as separate hidden inputs. The fields can carry credentials for different principals, and no contract requires consumers to reject both or apply a common precedence rule. Update the canonical specification to reject both fields together or define the selection rule. Regenerate this vendored file.

Automated sync of the public Comfy API v2 spec,
projected from the canonical contract (internal notes stripped).
Source:
cloud@98c09cb.It lands at
spec/openapi.yamland is a contract of itsown — it is never merged into another vendored spec in this repo.
This is the single rolling sync pull request for
spec/openapi.yaml. It liveson
chore/sync-v2-spec, and every later change to the upstream contractforce-updates this same branch and refreshes this description with the
new source commit — so there is only ever one open sync PR for this
spec, and its diff is always the current one.
Please do not push commits to this branch: the next sync would
overwrite them. (It will not do so silently — the workflow checks the
branch first and fails, naming this pull request, if it finds a commit
it did not make.) Push follow-up work to a branch of your own instead.
No regen commit needed. This sync ran
bash scripts/gen_models.shagainst thevendored spec and committed what it produced, so the generated low
layer in this pull request is already in step with
spec/openapi.yamland this repository's spec-drift check should be green asopened.
Green is not a substitute for reading the diff. The drift check
confirms only that the vendored spec and the generated low layer
agree with each other — it says nothing about whether either is what
the contract change meant, and the generated bytes were produced
upstream, by a generator this repository does not run. Review the
generated diff as you would any other.
