Not all fields are required for minimum import, but we recommend sending as many fields as are available. [This sample file](https://raw.githubusercontent.com/gr4vy/token-import-templates/main/token_import_sample.csv) provides an example of how this file can be populated. Our import process will not modify your token file, if column data is not truncated the record will be treated as a failure. ### Column Definitions | Column | Restrictions | Minimum Length | Maximum Length | Definition | | ---------------------------------------------------- | -------------------- | -------------- | -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `audit_reference_id` | Required, unique | | 200 | An ID for this row that we can use for logging and audit purposes. | | `merchant_account_id` | | | 22 | The merchant account ID that resources should be created for.
