string
A presigned URL valid for 15 minutes that allows direct PUT upload to cloud storage
string
The GCS URI (
gs://bucket/path) where the file will be stored. Use this value as signedReleaseFileUrl when creating verification orders. Alternatively, you can pass an HTTPS URL or inline base64 PDF directly in signedReleaseFileUrl — see Signed release file.Example Request

File Storage
Files are organized by tenant for security and isolation:Important Notes
- URL Expiration: The signed URL expires after 15 minutes
- File Type: Only PDF files are supported (
application/pdf) - File Size: There is currently no server-side size limit enforced on files uploaded through this signed-URL flow. As a best practice, keep uploads reasonably sized (a signed release form is typically well under 1MB). The 10MB cap documented for
signedReleaseFileUrlapplies only to the separate inline base64 upload path used by Create order — it does not apply here. - Tenant Isolation: Files are stored in tenant-specific directories
- Security: Files can only be accessed by the owning tenant
