The transaction ID will be the same as the quote ID to allow for easy tracking and correlation.You can optionally include custom entity metadata in the metadata field to store your own business data (e.g., reference numbers, categorization, reconciliation data). If not provided during creation, you can add it later using Set metadata.
Some types of transactions require you to pass user context headers, such as X-Uphold-User-Ip and X-Uphold-User-Agent Headers.
