MNTN API

openapi: 3.2.0

  title: MNTN Reporting API
  description: '## Overview


    Public partner reporting surface: **`GET /apilist`** (metadata) and **`GET` / `POST /apidata`**

    (query execution). Authenticate with your API key on each request.


    ## Data model


    Same reporting schema as the broader MNTN platform: **Info** tables (dimensions) and **Summary**

    tables (metrics), joinable on shared keys. Column names in requests use fully qualified identifiers

    (for example `campaigninfo.name`, `graph.impressions`).


    ## `/apilist`


    Returns tables and columns available to the authenticated advertiser.


    **Example**


    ```

    GET /apilist?format=json&key=YOUR_API_KEY

    ```


    ## `/apidata`


    Returns rows for the requested columns, date range, filters, and format.


    **Tips**


    - Prefer **`POST /apidata`** for large filter payloads.

    - Use pagination (`limit` / `offset`) where supported.

    - CSV/Excel exports may be row-capped; see rate limits in platform documentation.

        **Filter types — column predicates:** Each property key is a column identifier (`table.column`). The value can be:

        - **Operator object:** keys are operator names and values are comparison values (for example `{"equals": "Live"}`, `{"in": ["a","b"]}`).

        - **Scalar** (string or number): shorthand for `equals`.

        - **Array:** shorthand for membership (`in`).


        **Filter types — logical groups:** Properties named `AND`, `OR`, or `NOT` hold a nested object that follows the same rules (more column predicates and/or nested `AND` / `OR` / `NOT`).


        **Operator keys** (allowed keys inside an operator object): `equals`, `not`, `in`, `notIn`, `lt`, `lte`, `gt`, `gte`, `contains`, `notContains`, `startsWith`, `endsWith`, `hasAny`.


        Use **GET /apilist** to discover valid column identifiers (for `data`, `sum`, and `filter`).'
      example: '{"campaigninfo.id":{"in":["28915"]},"OR":{"campaigninfo.status":{"equals":"Live"},"graph.impressions":{"gte":1000}}}'
