Preview data sample
Preview data from a data source before creating it. Useful for validating data source configuration and examining data structure, column names, and sample values. The request body has the same encrypted **DSInfo** shape for every data source type (`s3`, `redshift`, `localfile`, etc.) — see [Create new data source](/docs/api-reference/data-sources/dss-create-post) for decrypted-equivalent examples covering all supported types.

Authorization
SymetryMLAuth HMAC-SHA256 signature-based authentication: requests are signed with
your secret key and sent with the Customer-ID, Sym-date,
Authorization, Content-MD5 and sym-version headers.
sym-version is required and must be 7.x (for example 7.0).
See SymetryML REST API Security
for the signature algorithm and a complete example.
