Webhook doesn't work

[AlexAtmtit]

Hi there,
I'm building my first workflow in Langflow and I have everything set up as I need it except for one thing - I can't get data from webhook. When I send data to my Datastax webhook cURL I see this in Postman.
It looks like the webhook requires authentication, but the Datastax settings say no authentication required for cURL webhook.
I had no problem setting up webhooks in n8n, Zapier, and other services, so it seems like I'm missing something here. Do I need to somehow turn on "receive mode" or something like that for webhooks to work? I'd appreciate if you could help!

Hey @AlexAtmtit! I'm here to help you with any bugs, questions, or contributions you have. Let's tackle this together!

Langflow requires authentication for incoming webhook requests, even if the external service, like Datastax, does not require it. This is done using an API key for security purposes. You need to ensure that your requests to Langflow include the necessary API key in the headers. This is likely why you're seeing issues with the webhook not working as expected ^[1].

Make sure to include the API key in your request headers when sending data to the Langflow webhook. This should resolve the issue you're experiencing. If you haven't set up an API key yet, you'll need to do so in Langflow's settings or configuration.

@dosu I have tried adding "Authorization" and "Bearer MY KEY" in the headers, but the result is the same.

Langflow requires the API key to be included in the request using the x-api-key header, not the Authorization header. Here's how you can format your request:

curl -X POST \
  "http://127.0.0.1:7860/api/v1/run/<your_flow_id>?stream=false" \
  -H 'Content-Type: application/json' \
  -H 'x-api-key: <your_api_key>' \
  -d '{"inputs": {"text":""}, "tweaks": {}}'

Make sure to replace <your_api_key> with your actual API key. This should help resolve the issue with the webhook authentication ^[1].

Unfortunately, no. A Langflow developer replied to me on Discord:
"Looks like a bug
Webhook is very experimental and there are plans to revamp it soon enough."

Please let me know if you find a fix!
