As within the Sigma app, there is a 1 million row download limit for CSV/XLSX types. To download more rows, you can batch your requests in up to 1 million row chunks, or consider using another export method such as exporting to Cloud Storage which has a 5 GB limit.
It can take an arbitrary amount of time for our system to process the data into a file and have it ready to be downloaded. While the file is being processed, requests to the query download endpoint will respond with the status code 204 No Content.
For security and privacy reasons, by default the queryId expires 1 hour after your export request has been processed by our system and the file has become ready for download.
If you call this API with an expired "queryId," you will receive a status code 404 Not Found with the error:
The query download has expired. For security & privacy reasons, the Exports are retained for one hour. A new queryId can be generated using the Workbook Export API.
If the "queryId" has expired, you can generate a new "queryId" using the Workbook Export API.
(This default expiration time can be overridden for up to 6 hours by setting the optional request parameter "resultsValidityTimeMs" in the export request.)
Permissions
If you encounter a permission error for the given endpoint, check with your organization Admin to verify your account type and permissions associated with your API token.
