Managing Custom Metadata

Define and assign custom metadata to accurately represent your organization’s unique data structures within your integration projects. Create metadata for inputs and outputs using common formats so your data transformations stay accurate. Custom metadata connects your visual development tools to your data requirements, facilitating easier testing and workflow creation.
