I have a query along the same lines.
First, answering the above.
To connect to a custom url, you must go to https://.app.n8n.cloud/home/credentials and add a new credential, select the option that suits you, because there is no option to ‘custom providers’ possibly the option that suits you is ‘OpenAI’, where you can put your api key and custom url.
And now… I’m testing API integrations with multiple apps, I would like being able to use our services with n8n.
I have been able to connect to our api, I successfully tested the connection.
But, I can’t list or manually add the models I have available.
Little side note, another question
I would be grateful if I could modify the name of the credential used (connection to the api). A common practice I’ve been seeing recently is adding the option to connect <‘OpenAI like’ providers>
