Overview

After creating segments, populate them with audience data using two methods:
  1. Real-time API - Live data streaming with immediate updates
  2. CSV Upload - Batch processing for larger datasets
Both methods use the same command syntax and operations.

​
Data Operations

All data operations use these commands:
  • ADD - Add segments to a key
  • REM - Remove specific segments from a key
  • DEL - Delete all segments from a key
  • SET - Overwrite all segments for a key (replaces existing)

​
Method 1: Real-time API

​
API Endpoint

POST https://api.agentic.scope3.com/rest/v1/signal/attach/[seat]/[keydef]
Where:
  • [seat] - Brand agent seat ID
  • [keydef] - Key definition, either simple (maid) or composite (domain,daypart)
The keydef must match what the segment was configured with during creation.

​
Request Format

Send operations in the request body, one per line: 
ADD abcd-2832-abcd-238-abcd segment1
REM aefa-9281-aefa-821-aefa segment2
DEL aaab-2712-aaab-132-aaab
SET d82a-1811-d82a-921-d82a segment1 segment3

​
Example Requests

Single Key Type (MAID): 
curl -X POST https://api.agentic.scope3.com/rest/v1/signal/attach/seat_123/maid \
  -H "Authorization: Bearer $SCOPE3_API_KEY" \
  -d "ADD d82a-1811-d82a-921-d82a premium_customers high_value"
Composite Key Type: 
curl -X POST https://api.agentic.scope3.com/rest/v1/signal/attach/seat_123/domain,daypart \
  -H "Authorization: Bearer $SCOPE3_API_KEY" \
  -d "SET example.com,morning premium_content morning_audience"

​
Method 2: CSV Upload

​
CSV File Format

CSV files use the same operation syntax: 
operation,key,segments
ADD,abcd-2832-abcd-238-abcd,segment1 segment2
REM,aefa-9281-aefa-821-aefa,segment2
DEL,aaab-2712-aaab-132-aaab,
SET,d82a-1811-d82a-921-d82a,segment1 segment3

​
Alternative: Action in Filename

If CSV lacks the operation column, specify action in filename: Filenames:
  • audience_add_20241201.csv - ADD operation
  • audience_rem_20241201.csv - REM operation
  • audience_del_20241201.csv - DEL operation
  • audience_set_20241201.csv - SET operation
File content (without operation column): 
key,segments
abcd-2832-abcd-238-abcd,segment1 segment2
aefa-9281-aefa-821-aefa,segment2

​
Upload Process

For CSV file uploads, follow the Scope3 API documentation: Scope3 File Upload Guide

​
Data Retrieval

Check what segments are assigned to a key: 
GET https://api.scope3.com/audience/[provider]/maid/d82a-1811-d82a-921-d82a
Response: 
TTL: 18321
segment1
segment3
All keys have a 30-day TTL. Keys not accessed within 30 days are automatically removed.

​
Best Practices

​
Real-time API

  • Batch multiple operations in a single request when possible
  • Use SET operations sparingly - they replace all existing segments
  • Monitor API response codes for processing status

​
CSV Upload

  • Use clear filenames indicating operation type and date
  • Include header rows in CSV files
  • Split large datasets into manageable batches
  • Use gzip compression for large files (.csv.gz)

​
Data Management

  • Regular cleanup using DEL operations for inactive keys
  • Monitor the 30-day TTL for key retention
  • Track segment record counts for billing purposes

​
Error Handling

Common scenarios:
  • Invalid keydef: Ensure keydef matches segment configuration
  • Seat not found: Verify seat ID exists and is accessible
  • Segment not found: Check segment exists for the specified seat
  • Format errors: Validate operation syntax and CSV structure

​
Next Steps

After populating segments:
  • Data is processed and available for targeting within 15 minutes
  • Monitor segment record counts via signals/list
  • Segments become available in campaign targeting options
