​
Overview

This endpoint creates an asynchronous export job that generates a downloadable file containing contact data for a specific date range. The export is processed in the background and returns a presigned download URL when complete. Use this endpoint when you need to extract large volumes of contact data efficiently. For real-time needs, use the List Contacts endpoint instead.
When to use exports: Exports are ideal for bulk data extraction (10,000+ contacts). For smaller datasets, use the paginated list endpoint.

​

string
required
Start date and time for exporting contacts in YYYY-MM-DD HH:MM:SS format. Exports contacts created from this timestamp in your space’s timezone.Example: 2024-01-15 00:00:00
​
end_date
string
required
End date and time for exporting contacts in YYYY-MM-DD HH:MM:SS format. Must be after start_date. Exports contacts created until this timestamp in your space’s timezone.Example: 2024-01-15 23:59:59

​
Optional Parameters

Export File Format

Completed exports are delivered as gzipped NDJSON (Newline-Delimited JSON) files. Each line contains a complete JSON object representing one contact record. 
{"id":123,"email":"[email protected]","name":"John Doe","phone":"+1234567890","location":"US","created_at":"2024-01-15T10:23:45Z"}
{"id":124,"email":"[email protected]","name":"Jane Smith","phone":"+9876543210","location":"CA","created_at":"2024-01-15T14:12:33Z"}
When include_comet_tokens=1 is specified: 
{"id":123,"email":"[email protected]","name":"John Doe","phone":"+1234567890","location":"US","created_at":"2024-01-15T10:23:45Z","comet_tokens":["token1","token2","token3"]}
{"id":124,"email":"[email protected]","name":"Jane Smith","phone":"+9876543210","location":"CA","created_at":"2024-01-15T14:12:33Z","comet_tokens":["token4","token5"]}
This format is ideal for streaming and processing large files line-by-line without loading the entire file into memory.

Notes

  • Rate Limit: This endpoint has a limit of 5 requests per minute per Space. See Rate Limiting for details.
  • Processing Time: Exports typically complete within seconds to a few minutes depending on data volume
  • Date Range: Specify any date range using start_date and end_date (interpreted in your space’s timezone)
  • Export Capacity: Can handle 100,000+ contacts per export efficiently
  • Status Checking: Use the Get Contact Export endpoint to check status (30 requests/min limit)
  • File Expiration: Download URLs expire after 15 minutes for security. Retrieve the file promptly after completion.
  • Security: Export files use UUID-based filenames with time-limited presigned URLs to prevent unauthorized access
  • Date Filtering: Contacts are filtered by created_at timestamp - only contacts created within the specified date range are included
  • Comet Tokens: Use the include_comet_tokens=1 parameter to include the last 5 comet tokens for each contact in the export file. This parameter is optional and defaults to 0.
