API Versioning

When backwards-incompatible changes are made to the API, a new dated version is released. See the changelog for available versions and what changed in each.

Requests that omit a version fall back to your organization's pinned version.

Base URL​

All Connect Server APIs use:

https://<region>.api.nabla.com/v1/connect/server

<region> is us or eu.

Targeting a specific version​

Add the X-Nabla-Api-Version header:

curl https://us.api.nabla.com/v1/connect/server/{endpoint} \
  -H "X-Nabla-Api-Version: 2026-04-24"

Via query parameter​

Alternatively, use nabla-api-version:

curl https://us.api.nabla.com/v1/connect/server/{endpoint}?nabla-api-version=2026-04-24
