Evolution API and n8n - how to configure?

[Ingodb]

Hi,
i have lates self hosted n8n and lates evolution API as docker image running.
evolution API is connected to my whatsapp and fully synced.
evolution community node is installed successfully.

I don’t get the credentials right. How do i connect the node to the evolution API? I want to fully use Whatsapp to read and write messages.

I can’t find any detailed guide or video, that explains that. Anyone here who can help?

evolution API

I checked my n8n server and enabled the Evolution API on it.
To install the Evolution API Docker image, you can run the container using the following command:

docker run -d \
    --name evolution-api \
    -p 8080:8080 \
    -e AUTHENTICATION_API_KEY=change-me \
    atendai/evolution-api

Please note that you can use localhost:8080, 127.0.0.1:80, or your-server-ip:8080 as the Server URL.
Make sure to replace AUTHENTICATION_API_KEY=change-me with your desired API key, and use that value as your ApiKey when making requests.

AUTHENTICATION_API_KEY

Hey, thanks so much. Solution was still different, but you gave me some motivation to go through everything once more.

Solution:

the n8n-evolution node credentials don’t accept the server API key. After installing the EVO Api and connecting a whatsapp account, each connected whatapps account gets an individual API Key.

Just by luck, i found that other key and tried it.

Ah someting else: I had to delete the port 8080 in the n8n node credentials. without the port, connections works fine.
