# Pushing data to the Celonis Platform using the Standard Data Ingestion API

The [Standard Data Ingestion API](/data-ingestion-api/standard/standard_overview) allows you to push real-time data to the Celonis Platform using your existing IT systems. This AWS S3 compatible API operates on events/notifications that get triggered whenever a new file reaches the API and automatically picks it up and processes it to a data pool.

When using the Data Ingestion API, the following apply:

* **File formats:** Uncompressed parquet files only. Alternative file formats must be converted to parquet before being ingested.
* **Extractions:** The Standard Data Ingestion API always performs delta loads. Make sure to define the primary keys to ensure proper updates and avoid duplicates.
* **File uploads:** Single files and multiple files simultaneously (using a first in, first out or FIFO method).
* **Data types:** Flat and nested.
