CSV template to schema conversion API endpoint

The /rpc/csv2schema endpoint in the Schema Registry API allows you to automatically create an Experience Data Model (XDM) schema using a CSV file as a template. Using this endpoint, you can create templates to bulk-import schema fields and cut down on manual API or UI work.

Getting started

The /rpc/csv2schema endpoint is part of the Schema Registry API. Before continuing, please review the getting started guide for links to related documentation, a guide to reading the sample API calls in this document, and important information regarding required headers that are needed to successfully make calls to any Adobe Experience Platform API.

The /rpc/csv2schema endpoint is part of the remote procedure calls (RPCs) that are supported by the Schema Registry. Unlike other endpoints in the Schema Registry API, RPC endpoints do not require additional headers like Accept or Content-Type, and do not use a CONTAINER_ID. Instead, they must use the /rpc namespace, as demonstrated in the API calls below.

CSV file requirements

To make use of this endpoint, you must first create a CSV file with appropriate column headers and corresponding values. Some columns are required, while the rest are optional. The table below describes these columns and their role in schema construction.

CSV header position CSV header name Required/Optional Description
1 isIgnored Optional When included and set to true, indicates the field is not ready for API upload and should be ignored.
2 isCustom Required Indicates whether the field is a custom field or not.
3 fieldGroupId Optional The ID of the field group a custom field should be associated with.
4 fieldGroupName (See description) The name of the field group to associate this field with.

Optional for custom fields not extending existing standard fields. If left blank, system will auto assign name.

Required for standard fields or custom fields extending standard field groups, which is used to query the fieldGroupId.
5 fieldPath Required The full XED dot-notation path for the field. To include all fields from a standard field group (as indicated under fieldGroupName), set the value to ALL.
6 displayName Optional The title or friendly display name for the field. Can also be an alias for the title if one exists.
7 fieldDescription Optional A description for the field. Can also be an alias for the description if one exists.
8 dataType (See description) Indicates the basic data type for the field. Required for all custom fields.

If dataType is set to object, either properties or $ref needs to also be defined for the same row, but not both.
9 isRequired Optional Indicates whether the field is required for data ingestion.
10 isArray Optional Indicates whether the field is an array of its indicated dataType.
11 isIdentity Optional Indicates whether the field is an identity field.
12 identityNamespace Required if isIdentity is true The identity namespace for the identity field.
13 isPrimaryIdentity Optional Indicates whether the field is the primary identity for the schema.
14 minimum Optional (For numeric fields only) The minimum value for the field.
15 maximum Optional (For numeric fields only) The maximum value for the field.
16 enum Optional A list of enum values for the field, expressed as an array (e.g. [value1,value2,value3]).
17 stringPattern Optional (For string fields only) A regex pattern that the string value must match in order to pass validation during data ingestion.
18 format Optional (For string fields only) The format for the string field.
19 minLength Optional (For string fields only) The minimum length of the string field.
20 maxLength Optional (For string fields only) The maximum length of the string field.
21 properties (See description) Required if dataType is set to object and $ref is not defined. This defines the object body as a JSON string (e.g. {"myField": {"type": "string"}}).
22 $ref (See description) Required if dataType is set to object and properties is not defined. This defines the $id of the referenced object for the object type (e.g. https://ns.adobe.com/xdm/context/person).
23 comment Optional When isIgnored is set to true, this column is used to provide the schema’s header information.

Refer to the following CSV template to determine how your CSV file should be formatted.

Create an export payload from a CSV file

Once you have set up your CSV template, you can send the file to the /rpc/csv2schema endpoint and convert it to an export payload.

API format

POST /rpc/csv2schema

Request

The request payload must use form data as its format. The required form fields are shown below.

curl -X POST \
  https://platform.adobe.io/data/foundation/schemaregistry/rpc/csv2schema \
  -H 'Authorization: Bearer {ACCESS_TOKEN}' \
  -H 'x-api-key: {API_KEY}' \
  -H 'x-gw-ims-org-id: {IMS_ORG}' \
  -H 'x-sandbox-name: {SANDBOX_NAME}' \
  -F 'csv-file=@"/Users/userName/Documents/sample-csv-template.csv"' \
  -F 'schema-class-id="https://ns.adobe.com/xdm/context/profile"' \
  -F 'schema-name="Example Schema"' \
  -F 'schema-description="Example schema description."'
Property Description
csv-file The path to the CSV template stored on your local machine.
schema-class-id The $id of the XDM class that this schema will employ.
schema-name A display name for the schema.
schema-description A description for the schema.

Response

A successful response returns an export payload that was generated from the CSV file. The payload takes a form of an array, and each array item is an object that represents a dependent XDM component for the schema. Select the section below to view a full example of an export payload generated from a CSV file.

Import the schema payload

After generating the export payload from the CSV file, you can send that payload to the /rpc/import endpoint to generate the schema.

See the import endpoint guide for details on how to generate schemas from export payloads.
