API authentication

Cloud

Cloud v3 uses a bearer token created from your Presenton account.

Authorization: Bearer YOUR_API_TOKEN

Send the token only to the official Cloud API base URL. Store it in a secret manager and rotate it after suspected exposure.

Self-hosted

Self-hosted v1 uses HTTP Basic authentication when an admin account is configured.

curl --request GET \
  --url http://localhost:5001/api/v1/ppt/presentation/all \
  --user "$PRESENTON_USERNAME:$PRESENTON_PASSWORD"

MCP uses a bearer session token obtained from the self-hosted authentication endpoint. Credential rotation invalidates existing sessions and MCP tokens.

Never place Cloud tokens, self-hosted passwords, or MCP bearer tokens in source control, client-side code, documentation examples, or support requests.
