Databricks Federated Token Exchange Returns HTML Login Page Instead of Access Token(GCP →Databricks)

Hi everyone,

I’m trying to implement federated authentication (token exchange) from Google Cloud → Databricks without using a client ID / client secret only using a Google-issued service account token. I have also created a federation policy in Databricks.

const audience = "https://accounts.gcp.databricks.com"; const resp = await axios.post( "https://accounts.gcp.databricks.com", qs.stringify({ grant_type: "urn:ietf:params:oauth:grant-type:token-exchange", subject_token: accessToken, subject_token_type: "urn:ietf:params:oauth:token-type:jwt", audience, requested_token_type: "urn:ietf:params:oauth:token-type:access_token", }), { headers: { "Content-Type": "application/x-www-form-urlencoded" } } );

Which API should i use instead of "https://accounts.gcp.databricks.com"?

<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width,initial-scale=1"> <meta name="description" content="Databricks Sign in"> <title>Databricks - Sign in</title> ... </html>

Can anyone help me to solve this error or provide any document for this Federated Token Exchange (GCP →Databricks).

You might want to check whether the issue is related to your federation policy configuration.

Try reviewing the following documentation to confirm that your policy is correctly set up (issuer, audiences, and other expected claims):
