Data Loader API upload requirements

Learn about the API requirements for uploading different file types and sizes in the Reltio Data Loader.

The Data Loader API has different requirements for uploading different file formats. To learn about and access the Reltio Data Loader API, see topic: Reltio Swagger.

Important: We limit the number of records in a single file to a maximum of 10M records. The limitation applies to all supported formats. For files with large data amounts, we recommend that you split your load into batches with no greater than 1M records each.
