Bug Description

The Bitbucket Trigger credential validation in n8n fails when using the new Atlassian scoped API tokens for Bitbucket Cloud.

The same token works successfully in Postman and direct Bitbucket API calls, but n8n shows:

Authorization failed - please check your credentials

or:

Your credentials lack one or more required privilege scopes

even when all required Bitbucket scopes are enabled.

To Reproduce Open Atlassian API token management Create a scoped API token for Bitbucket Cloud Enable scopes: read:user:bitbucket read:workspace:bitbucket read:repository:bitbucket read:webhook:bitbucket write:webhook:bitbucket delete:webhook:bitbucket Open n8n → Credentials → Bitbucket API Enter: Email = Atlassian email or Bitbucket username Access Token = newly generated scoped token Click Save Expected behavior

n8n should validate the credential successfully and allow Bitbucket Trigger usage with Atlassian scoped API tokens.

Actual behavior

Credential validation fails with:

Authorization failed - please check your credentials

or:

Your credentials lack one or more required privilege scopes

even though:

the token is valid the token works in Postman Bitbucket API endpoints respond correctly webhook scopes are included

Verification

The same token works successfully using curl:

curl -u "[email protected]:API_TOKEN"
https://api.bitbucket.org/2.0/user

Response returns valid user JSON.

Only n8n credential validation fails.
