Authorizations

Authorization
string
header
required

The authorization field takes the session bearer returned by sign-in, or an API key where the route allows keys. Paste the token itself into the authorization field. When invitation-only access is enabled, private operations require the account's sign-in email to be invited. Sign-in can complete without an invitation, but private HTTP, MCP and FIX operations refuse with access_not_allowlisted (HTTP 403): "Private access is limited to invited accounts. Contact support to request access." Public market data remains available. Invitation changes apply to the next private operation, including existing FIX sessions. Do not retry until support confirms access.
