  • IAM Delegated Access
  • Signed URLs (https URLs only)

​
Parameters

ParameterRequiredDescription
row_dataYeshttps path to a cloud-hosted audio. For IAM Delegated Access, this URL must be in virtual-hosted-style format. For older regions, your S3 bucket may be in https://<bucket-name>.s3.<region>.amazonaws.com/<key> format. If your object URLs are formatted this way, make sure they are in the virtual-hosted-style format before importing.
global_keyNoUnique user-generated file name or ID for the file. Global keys are enforced to be unique in your org. Data rows will not be imported if its global keys are duplicated to existing data rows.
media_typeNo"AUDIO" (optional media type to provide better validation and error messaging)
metadata_fieldsNoSee Metadata.
attachmentsNoSee Attachments and Asset overlays.
