> Release notes for the Oviond REST API.

<Update label="2026-02-25" description="Calculated & saved metrics">
  ### Custom KPIs and reusable queries

  Define formulas that combine metrics across data sources, and save query configurations you reuse across reports.

  * `POST /v1/calculated-metrics` — define a formula (`POST /v1/calculated-metrics/{id}/duplicate` to clone)
  * `POST /v1/saved-metrics` — save a query config (`POST /v1/saved-metrics/{id}/duplicate`)
</Update>

<Update label="2026-02-18" description="Custom data">
  ### Bring your own datasets

  Upload CSV or JSON datasets and query them alongside connected data sources.

  * `POST /v1/custom-data` — upload and parse a dataset
  * `PUT /v1/custom-data/{id}` and `POST /v1/custom-data/{id}/duplicate`
</Update>

<Update label="2026-02-11" description="Data query engine">
  ### Pull metrics from any source

  A single query API resolves metrics and breakdowns across every connected platform, with a dry-run test path.

  * `POST /v1/data/query` — pull metrics
  * `POST /v1/data/test` and `GET /v1/data/accounts`, `GET /v1/data/resource`
  * `POST /v1/datasources/test` — verify a connection
</Update>

<Update label="2026-02-04" description="Data sources">
  ### Connect marketing platforms via OAuth

  OAuth 2.1 connection flow for Google Analytics, Meta Ads, LinkedIn, and the rest of the data-source catalog. Auth profiles link to clients; an account or property is chosen per connection.

  * `POST /v1/datasources/auths` — create an auth profile from an OAuth grant
  * `POST /v1/datasources/{client_id}/link` and `POST /v1/datasources/{client_id}/unlink`
  * `GET /v1/datasources/{datasource_id}/profiles` — manage connection profiles
