Use it to pick up new projects between full syncs. It matches on the project’s creation, so new tenders on existing projects still need a full sync. See <a href="https://developer.api.estimateone.com/guides/incremental-crm-sync.html">Incremental CRM sync</a>.</li> <li><code>Added</code> — Each project carries <code>createdAt</code>, when it was added to E1 (RFC 3339, UTC).</li> <li><code>Added</code> — Each tender carries the builder’s <code>description</code> (plain text) and the estimated construction dates, <code>estimatedStartDate</code> and <code>estimatedEndDate</code>.</li> <li><code>Added</code> — Each consultant carries <code>types</code>, its disciplines on the project (e.g. <code>ARCHITECT</code>, <code>ENGINEER_STRUCTURAL</code>), so you can tell architects from engineers.</li> </ul>Addedhttps://developer.api.estimateone.com/reference/changelog.html#2026-09-30https://developer.api.estimateone.com/reference/changelog.html#2026-09-30Wed, 30 Sep 2026 00:00:00 GMT<ul> <li><code>Added</code> — Speci-finder results are now served from <code>GET /api/tender/supplier/v1/companies/{companyId}/speci-finder/results</code>. API paths are now namespaced by the E1 platform serving them, so that each platform’s surface is distinct as more are added. The response shape is unchanged.</li> <li><code>Deprecated</code> — The previous path, <code>GET /api/supplier/v1/companies/{companyId}/speci-finder/results</code>, is superseded. <strong>No action is required</strong>: it keeps working indefinitely and returns identical responses. Its responses now carry <code>Deprecation</code> and <code>Link: &#x3C;...>; rel="successor-version"</code> headers, and it is marked <code>deprecated</code> in the OpenAPI spec. Move to the new path when convenient. See <a href="https://developer.api.estimateone.com/reference/versioning.html#superseded-paths">Superseded paths</a>.</li> </ul>AddedDeprecated
