# Update brand logo (signed)

> Update the logo for a brand by uploading raw bytes (multipart/form-data) using a short-lived, single-use token minted via the bloom_create_logo_upload_url MCP tool. The token in the path is the credential — no Authorization header is expected. Same validation/storage pipeline as PUT /brands/{id}/logo/file.
