# Upload a dataset's sample redaction

> Store the redaction for a dataset's sample, replacing whatever was there before. Uploading also
brings back a redaction that was previously deleted.

Two kinds of caller may upload: a customer with write access on datasets, or Narrative with admin
access on datasets. A customer's dataset is resolved inside their own company. Narrative's is
resolved by id alone, with no company scoping, which is what lets Narrative write a redaction for
a customer's dataset.

The stored redaction records who wrote it from your access token, so a `written_by` field in the
request body is ignored.

`model_version` names the privacy model that produced a redaction, and only Narrative may set it.
A customer sending it is refused with a 400 rather than dropped, so reading back a redaction
Narrative generated and sending it straight here needs `model_version` removed first. An upload
that leaves the field out clears a stored value, so a redaction you edit stops claiming a model
produced it.

    The [Narrative Data Collaboration Platform](https://app.narrative.io) API is
    organized around REST. Our API has predictable resource-oriented URLs,
    accepts form-encoded request bodies, returns JSON-encoded responses, and
    uses standard HTTP response codes, authentication, and verbs.



    The current version is a pre-release beta.  It may result in unexpected
    behavior and there may be breaking changes in future releases up to the 1.0
    release.

    description: >-
      Access rules let data providers control who can purchase their data and
      the terms of purchase.


      The `access-rules` API allows you to manage access rules for your
      datasets.

  - name: Agent Conversations
    description: >-
      Build LLM-driven workflows that can call MCP tools, ask the caller for
      input, and return structured answers.


      A conversation pins a model, a system prompt, and a tool catalog. Each run
      sends the model a user message (or

      a batch of tool outputs from a previously-paused run); the model decides
      whether to answer directly, call a

      server-side tool (resolved by the platform via Model Context Protocol), or
      call a client-side tool (which pauses

      the run with `requires_action` and waits for the caller to reply).

  - name: MCP Connections
    description: >-
      Connect external (non-Narrative) MCP servers so agent runs can call their
      tools with the

      calling user's own OAuth authorization.


      A connection is created interactively: `POST /mcp-connections` runs OAuth
      discovery and

      Dynamic Client Registration against the server and returns a consent URL;
      the user authorizes

      in a browser; the authorization server redirects to `GET
      /mcp-connections/callback`, which

      stores the authorization code and sends the browser on to the Narrative
      app; the app calls

      `POST /mcp-connections/complete` with the user's own bearer token, which
      exchanges the code and

      marks the connection `connected`.


      That last step is authenticated on purpose. The callback is public — it's
      a cross-site browser

      redirect, so no bearer reaches it — so it is not allowed to complete
      anything. Only the user

      who started the flow can turn the stored code into a token.


      Tokens are stored encrypted and used server-side — they are never returned
      by the API. Once

      connected, reference the connection by id from an agent run's
      `mcp_servers[].connection_id`.
  - name: App Invites
    description: >-
      App invites allow applications to create one-time, shareable links on
      behalf of their users. These links

      enable users to invite third parties who do not have a Narrative account
      to perform actions within the

      application.


      For example, a Narrative user can send an invite link to a third party who
      then completes a Pinterest

      OAuth flow and creates a connector profile in the inviter's account,
      allowing the inviter to deliver

      audience data to the third party's Pinterest account without the third
      party needing a Narrative account.


      This API is intended to be used by applications (via app client
      credentials) to create and manage invites

      on behalf of their users, which can then be shared with invitees.
  - name: Apps
    description: >-
      Apps are applications bundled with a UI that can perform various actions
      on behalf of a user utilizing the Narrative API.

  - name: Access Tokens
    description: >-
      System Access Tokens are long-lived bearer credentials for calling the API
      without a user present.


      A token belongs to a company, carries an explicit list of permissions, and
      expires on a date you choose — at

      least a day out and at most a year. `admin` access cannot be granted to
      one.


      `POST /access-tokens/tokens` is the only endpoint that returns the
      credential. Everything after that works in

      terms of the token's id: the list, get and update responses describe a
      token without ever repeating its

      `access_token`. If you lose it, delete the token and create another.

    description: >-
      The `data-stream` API endpoints allows one to create and update
      data-streams. Additionally the endpoints allow

      finding data-streams using free text search. A few of the endpoints are
      behind authorization.


      Update endpoint allows a client to post an edited data-stream document as
      is, without having to change its shape.

      The API ensures that only certain fields are allowed to be modified.
      Attempts to modify fields not up for client

      modifications are ignored.

    description: >-
      Any kind of data, in any schema, can be pushed into the Narrative Data
      Collaboration Platform as a dataset exactly as it is stored in your own
      system.


      The `datasets` API allows you to manage your datasets.
  - name: Derivations
    description: >-
      Derivation rules describe how the value of one Rosetta Stone attribute can
      be computed from another — for

      example, hashing a raw email into a SHA-256 hashed email. Each rule
      carries a transformation expression that

      reads the source attribute's value through `$source`.


      The `derivations` API allows you to browse the rules your company can use
      — the ones it owns plus the ones

      shared with it through collaborators. Creating and changing them requires
      an `admin` grant on

      `attribute_derivations`, and a rule can only be changed by the company
      that owns it.
  - name: Destinations
    description: >-
      Destinations associate a subscription to a profile. Optionally, ad-hoc
      quick settings can be configured to a destination.

      Those quick settings have to match the format defined on the app manifest.
  - name: Installations

  - name: Jobs
    description: >-
      Jobs represent an operation done on a given data plane. All jobs today are
      tied to a query that represents a forecast or a materialized view.


      The jobs API provides an interface for interacting with the jobs table,
      which stores various operations involving reading or writing data. This
      API allows users to retrieve detailed information about specific jobs,
      including NQL forecasts and materialized views.
  - name: Mappings
    description: >-
      A mapping is a transformation from a dataset to an attribute. Defining a
      mapping between a dataset and an attribute makes the dataset eligible to
      participate in subscriptions where a buyer is purchasing the target
      attribute.

      Models can be stored in HuggingFace or Narrative repositories and have
      configurable

      collaborator permissions for training and inference access.


      The `models` API allows you to list, retrieve, and update models
      accessible to your company.
  - name: NQL
    description: >-
      Narrative Query Language (NQL) is a specialized, SQL-inspired language
      designed to query and manipulate data within the Narrative platform. While
      it looks and feels much like standard SQL, it offers extended
      functionality and syntax that let you leverage platform-specific
      features—such as referencing datasets by their IDs, creating materialized
      views, or generating forecasts—without having to manage the complexities
      of different query engines behind the scenes. NQL queries can ultimately
      compile down to multiple underlying engines (e.g., Snowflake, Spark) to
      execute your requests efficiently in the Narrative ecosystem.

    description: >-
      App profiles are associated with an installation. They represent a
      reference to a configuration that the app can use to save confidential
      information outside of Narrative's control.

      Profiles are currently used to configure settings for connector apps.
  - name: Resources
    description: >-
      Narrative gives you access to managed resources, like your own AWS S3
      bucket, so that you can effortlessly buy and sell data on the platform.


      The `resources` API allows you to manage your resources.
  - name: Schema Inference
    description: >-
      The `schema-inference` API analyzes submitted files to automatically infer
      and return their structure as a dataset schema.
  - name: Schema Presets
    description: >-
      The `schema-presets` API allows you to list the available schema presets,
      get detailed information about a specific one and manage its life cycle.


      You can create a schema preset from scratch or create one based on an
      existing one, administrators can create platform wide available (public)
      schema preset.
  - name: Subscriptions
    description: >-
      In the Narrative Data Collaboration Platform a subscription represents a
      set of rules dictating the commercial terms related to the licensing of
      data.


      The `subscriptions` API allows you to set and get information about
      `subscription` objects owned by the authenticated account.
  - name: Uploads
    description: >-
      The `uploads` API allows you to send files to Narrative and use them to
      perform tasks like creating a list or adding data to a dataset.
  - name: Usage
    description: >-
      The `usage` API enables the recording of usage events associated with a
      product.
  - name: Webhooks
    description: >-
      Webhooks push events to a URL you control instead of making you poll for
      them.


      You create a subscription with the endpoint you want events sent to and a
      filter describing which events you

      want. Two kinds of subscription exist: job subscriptions follow the
      lifecycle of Narrative jobs, and app

      subscriptions follow the events a Narrative app reports through `POST
      /apps/events`.


      Creating a subscription returns a `secret`. Narrative sends it back in the
      `X-Narrative-Secret` header on

      every delivery, and comparing the two is how you tell a real callback from
      a forged one — so store it and do

      not share it.


      Deliveries are described under the "Event delivery" webhook below. Return
      any 2xx; anything else is retried

      with exponential backoff, and because a retry reuses the envelope's `id`,
      handlers should be idempotent

      on it.
  - name: Workflows
    description: >-
      The `workflows` API allows you to create, schedule, trigger, and archive
      workflows.

      Workflows are defined using a serverlessworkflow YAML specification.

      summary: Upload a dataset's sample redaction
      description: >-
        Store the redaction for a dataset's sample, replacing whatever was there
        before. Uploading also

        brings back a redaction that was previously deleted.


        Two kinds of caller may upload: a customer with write access on
        datasets, or Narrative with admin

        access on datasets. A customer's dataset is resolved inside their own
        company. Narrative's is

        resolved by id alone, with no company scoping, which is what lets
        Narrative write a redaction for

        a customer's dataset.


        The stored redaction records who wrote it from your access token, so a
        `written_by` field in the

        request body is ignored.


        `model_version` names the privacy model that produced a redaction, and
        only Narrative may set it.

        A customer sending it is refused with a 400 rather than dropped, so
        reading back a redaction

        Narrative generated and sending it straight here needs `model_version`
        removed first. An upload

        that leaves the field out clears a stored value, so a redaction you edit
        stops claiming a model

        produced it.

            Raised when a column's `masking_strategy` isn't one of the seven
            supported strategies, when

            `keep_last_digits` asks to keep a number of digits outside 1 to 4,
            when a column's `category`

            isn't one of the nine supported categories, when `columns` exceeds
            its `maxItems`, when

            `model_version` is blank or longer than 128 characters, or when
            `model_version` is sent by a

            caller who may not set it.


            `error_description` points at the offending column by its position
            in `columns`. An

            unrecognised `type` is reported with the value that was sent and
            every type that is accepted:


            ```

            DecodingFailure at .columns[0].masking_strategy: unexpected type
            'keep_emial_domain'. expected one of keep_email_domain,
            keep_initials, keep_last_digits, keep_network_prefix,
            keep_two_decimal_places, keep_year, mask_everything

            ```


            A recognised `type` with an unusable body is reported at the field
            that was wrong, so a

            `keep_last_digits` asking for too many digits fails at `count`:


            ```

            DecodingFailure at .columns[0].masking_strategy.count: 999 digits
            must be at most 4

            ```


            An unrecognised `category` is reported the same way, at the column's
            own `category`, with

            every category that is accepted:


            ```

            DecodingFailure at .columns[0].category: unexpected category
            'national_id'. expected one of account_number, other,
            private_address, private_date, private_email, private_person,
            private_phone, private_url, secret

            ```


            Too many columns is reported at the document root rather than at a
            column, because the array

            as a whole is what was refused:


            ```

            DecodingFailure at : a redaction must name at most 20480 columns,
            not 20481

            ```


            A `model_version` that is blank, or whitespace only, or longer than
            128 characters is reported

            at its own field:


            ```

            DecodingFailure at .model_version: a model version must be at most
            128 characters

            ```


            A `model_version` you may not set is refused after the body has
            decoded, so a value that is

            both forbidden and unusable fails as the decode failure above rather
            than here. This is the one

            400 on this endpoint that isn't a decode failure: `error` is
            `invalid_request`, where every

            case above is a `bad_payload`.


            ```

            only Narrative may set a redaction's model version: remove
            model_version from the request body

    RedactedColumn:
      description: >-
        One column of the sample, the kind of personal data it holds, and how it
        is masked. The category

        does not constrain the strategy: a redaction you upload can pair any
        category with any strategy.
      type: object
      required:
        - path
        - masking_strategy
      properties:
        path:
          description: >-
            Dot-separated path to the column in the sample, e.g. `email_address`
            or

            `payment.card_number`. A path that doesn't resolve in a row leaves
            that row untouched, so a

            redaction naming a since-renamed column quietly stops masking it.
          type: string
          example: email_address
        category:
          oneOf:
            - $ref: '#/components/schemas/PersonalDataCategory'
            - type: 'null'
          description: >-
            Optional on a redaction you upload: send `null` or leave the key out
            for a column you don't

            want to classify. The privacy model sets it on the redactions it
            writes. Nothing masks by the

            category, only by `masking_strategy`, which is why the category may
            be left out and the

            strategy may not. A stored redaction always returns the key, `null`
            for a column with no

            category.
        masking_strategy:
          $ref: '#/components/schemas/MaskingStrategy'
      example:

    PersonalDataCategory:
      description: >-
        The kind of personal data found in a column. Nine values are accepted:


        - `account_number`

        - `other`

        - `private_address`

        - `private_date`

        - `private_email`

        - `private_person`

        - `private_phone`

        - `private_url`

        - `secret`


        The privacy model produces every one of them except `other`, which is
        for a redaction you upload

        yourself when none of the other eight fit.


        On write, a value outside that list is rejected with a 400 that names
        the value it refused and

        lists all nine that are accepted.


        Both read endpoints answer 500 for a stored `category` this API can't
        read, rather than

        reporting or masking by something nobody wrote.

    MaskingStrategy:
      description: >-
        How a column's value is masked. Seven variants, each a JSON object
        tagged with `type`:


        - `keep_email_domain`: keeps the domain, plus the local part's first and
        last two characters
          (or just its first character when the local part is two to four characters long, and nothing
          at all when it is one character). A value with no `@`, or one that starts with `@` and so has
          no local part, is masked completely, domain included: `@example.com` masks to `************`.
        - `keep_initials`: replaces each whitespace-separated token with its
        first letter and three mask
          characters, whatever the token's length, so `John Doe` becomes `J*** D***`.
        - `keep_network_prefix`: keeps an IPv4 address's `/24` and masks the
        rest. Anything else, IPv6
          included, is masked completely.
        - `keep_two_decimal_places`: rounds a coordinate to two decimal places.
        A value that isn't a
          coordinate is masked completely.
        - `keep_year`: returns the first four-digit run in the value and drops
        the rest, so `1985-03-12`
          becomes `1985`. A value with no four-digit run is masked completely.
        - `keep_last_digits`: keeps the last `count` digits, masks every other
        letter and digit, and
          leaves separators alone so the value's shape survives. When the value has no other letter or
          digit to mask it keeps one digit fewer, so `1234` with `count: 4` masks to `*234`.
        - `mask_everything`: keeps nothing.


        On write, an unrecognised `type` is rejected with a 400 and nothing is
        stored. The 400 names the

        column it refused, the value it didn't recognise, and all seven types it
        accepts. Accepting the

        typo and masking some other way instead would be worse than refusing:
        someone who typed

        `keep_emial_domain` would believe the domain was being kept, see
        fully-masked values, and get

        nothing telling them the strategy they asked for wasn't the one in use.


        Both read endpoints answer 500 for a stored `masking_strategy` this API
        can't read, rather than

        naming a strategy nobody wrote or masking by one. That 500 carries a
        `log_id` and not the column

        that failed, so quote it when you report the failure.
