How to assign activity and interest categories to an exhibitor

Use this guide when you need to set an exhibitor's business matching categories — both the activities they offer and the interests they're looking for.

What you'll need before starting

What you need	Where to get it
Product category IDs	`GET /api/v2/categories/get` — returns the product categories configured for the event. These same IDs are used for both activity and interest assignments

Request

Bash

curl -X POST "https://your-event-domain.com/api/v2/exhibitor/set" \
  -H "Authorization: Bearer your_api_key_here" \
  -F "event_id=7" \
  -F "exhibitor_id=1200" \
  -F "activity_categories=101,102,105" \
  -F "interest_categories=201,203"

Notes

activity_categories — comma-separated IDs of what the exhibitor offers
interest_categories — comma-separated IDs of what the exhibitor is looking for
Both fields use product category IDs from GET /api/v2/categories/get — these are not exhibitor category IDs
Passing new values replaces the existing category assignments — include all IDs the exhibitor should have, not just the new ones
You can identify the exhibitor by exhibitor_id, external_id, or username
