Track changes

Use GET /offers/{id}/changelog to page through changes to an offer and its related items and assets. The newest changes appear first.

const response = await fetch(
  "https://api.egdata.app/offers/offer-id/changelog?page=1&limit=10",
);
const result = await response.json();

The response includes elements, pagination details, and each change's timestamp, metadata, and available catalog context:

{
  "elements": [
    {
      "timestamp": "2026-09-30T10:00:00.000Z",
      "metadata": {
        "contextId": "offer-id",
        "contextType": "offer",
        "changes": [{ "field": "title", "oldValue": "Old title", "newValue": "New title" }]
      }
    }
  ],
  "page": 1,
  "limit": 10,
  "totalCount": 1,
  "totalPages": 1,
  "hasNextPage": false
}

Use page and limit to continue through the list (page defaults to 1, limit defaults to 10 and is capped at 50). Optional query, type, and field parameters narrow changes by text, change type, or changed field. Missing enrichment does not prevent a change record from being returned; context is best effort.

For cross-catalog change search, use GET /search/changelog; for a specific record, use GET /changelist/{id}. Both are listed in the API reference.
