Limits

The limit of 1000 custom file segments is calculated only for the file segments that are active. Most of our customers utilize only 30-40% of this limit at any given point.
Rate Limit NameRate Limit
total active segmentThe limit of the total number of active custom segments at a time for a client is 1000.
file_segment ops per hourThe total number of file segment operations (create/add/remove) per hour per client allowed is 10.
file_segment ops per dayThe total number of file segment operations (create/add/remove) per day per client allowed is 100.
file_segment users per dayThe total number of users uploaded via the File segment is limited to 2 million per day. (This limit is customizable, please get in touch with support)
file_size_limitThe size of the file from which the segment is created/updated. For each request, the file size limit is 150 MB.

​
Notes

​
Limits

  • Breaching the limits will reject the request.
  • Per hour and per day limits will consider the calculation based on the last hour and last 24 hrs respectively.

​
CSV File Requirements

  • The attribute names should be separated by new lines.
  • CSV should be a single column and less than 150MB.
  • Values should not end with a comma (e.g., abcd not abcd,).
  • Values should not have duplicates or special characters (e.g., abcd not "abcd" or a#bc).
  • File should not have empty rows or columns.
  • A user attribute value must uniquely identify a single user.
  • Sample File Link

​
Segment Processing & Availability

As soon as the request is received at the MoEngage system, MoEngage creates a custom segment with zero users. After this, the file is processed and users are added to the custom segment. If the created custom segment is queried in between the file processing, it will show zero or partial user count.
