When i try to use a workflow via the comfyui API, i get this error:
Is there a way to authenticate so i can use it in an automated way and not only via the Webinterface?

got prompt

In the web GUI i am logged in with the API Key (just in case this info is important)

You’ve got two separate issues in that stack trace—one is a node/version mismatch, the other is missing API auth.

1. WAS_Load_Image.IS_CHANGED() got an unexpected keyword argument 'RGBA'

Why it happens: Your workflow JSON is passing an input named RGBA to the WAS Suite loader node, but your installed version of ComfyUI-WAS-Node-Suite doesn’t expose that keyword anymore (its schema changed). ComfyUI then throws on the unexpected arg.

Fix it (pick one):

A. Update the WAS node pack to match your workflow

In Windows Terminal:

cd "C:\AI\ComfyUI-Studio\App\ComfyUI\custom_nodes\ComfyUI-WAS-Node-Suite"
git pull

(Or use ComfyUI-Manager → Installed → Update all.)

Restart ComfyUI.

B. Or, edit the workflow to match your installed WAS version

Open the workflow JSON you’re running.

Find the block for WAS_Load_Image and remove the "RGBA": true/false field entirely. (Recent builds infer alpha if present; older builds used different names like “RGBA Output” / “convert_mode”. If you see a dropdown-style mode or convert_mode, set it there instead.)

Save, reload the workflow.

Tip: After updating nodes, delete pycache folders under custom_nodes\ComfyUI-WAS-Node-Suite and restart if ComfyUI still complains.

2. Unauthorized: Please login first to use this node. (BFL Flux Pro)

This is coming from comfy_api_nodes\apis\client.py when the BFL/Flux Pro API node runs. It needs a valid API key/session and can’t find one.

Fix it: add your BFL key (or log in) so the node can authenticate.

Option A — Environment variable (easy & reliable)

Open PowerShell:

Close ComfyUI completely and relaunch it.

Option B — .env file in ComfyUI root

Create a file:

C:\AI\ComfyUI-Studio\App\ComfyUI.env

Put:

BFL_API_KEY=<YOUR_KEY_HERE>

Restart ComfyUI.

Option C — ComfyUI Studio/Manager UI (if exposed)

Settings → API Keys (or the node’s settings panel) → add BFL_API_KEY → paste key → Save → Restart.

If your node is “Flux Pro”/“BFL Cloud,” it requires a paid/cloud key. Local-only models won’t need this, but any of the nodes_bfl.py API ops will.
