ds.setSchema REST

Skip to end of metadata
Go to start of metadata



This method allows specifying a schema for a data type in Gigya's Data Store (DS). The schema sets field names, data types, formatting and encryption as well as client side access restrictions. Data object schemas act as meta-data, guiding Gigya how to handle the data in the specified fields.

  • Depending on schema setting, other fields can be added to the storage outside the schema, Gigya will add them as is without special treatment. 
  • Field deletion: a field in the Data object schema is eligible for deletion if no data has been saved to it. To delete a field in the schema, you need to set it to null (see example below).
  • Changes to schema are incremental, when setting the schema for part of the fields, the properties of the omitted fields remain unchanged. 
  • Unless specified otherwise, schema defined fields are only accessible from the server.


Note: For security reasons this method is not available for client side SDKs, only for server side SDKs.

Note: If you plan on integrating the DS, we highly recommend reading the Data Store Guide.
The DS is a premium platform that requires separate activation. If the DS is not part of your site package please contact your Gigya Account Manager or email support@gigya-inc.com.

Request URL

Where <Data_Center_ID> is:
  • us1 - For the US data center.
  • eu1 - For the European data center.
  • au1 - For the Australian data center.
  • ru1 - For the Russian data center.

If you are not sure of your site's data center, see Finding Your Site's Data Center.


typestring A string indicating the type of the object, equivalent to a schema name. The objective of this field is to classify objects as sharing the same schema.
dataSchemaJSON objectA JSON object defining the schema to be set. See the format definition of the schema object below. 
format string Determines the format of the response. The options are:
  • json (default)
  • jsonp - If the format is jsonp then you are required to define a callback method (see parameter below).
callback string This parameter is required only when the format parameter is set to jsonp (see above). In such cases this parameter should define the name of the callback method to be called in the response, along with the jsonp response data.
httpStatusCodes Boolean The default value of this parameter is false, which means that the HTTP status code in Gigya's response is always 200 (OK), even if an error occurs. The error code and message is given within the response data (see below). If this parameter is set to true, the HTTP status code in Gigya's response would reflect an error, if one occurs.

Authorization Parameters

Each REST API request must contain identification and authorization parameters.

Please refer to the Authorization Parameters section for details. 

Schema Object

uniqueArrayAn array defining the fields on which you wish to impose a constraint of uniqueness. You may impose a compound uniqueness constraint based on a set of fields (see the example below). Only regular primitive data fields can be defined as unique.
Note: Setting fields to be "unique" only works going forward, so if the fields already have non-unique values, the non-unique values will remain.
fieldsJSON objectThis object defines properties per data fields. The object contains field names and their corresponding list of properties (see the example below). The field name should be the full path name with dots, i.e. "work.address".
The properties in option are:
  • type - Defines the data type of this field. The supported values are "integer", "float", "boolean", "string", "date", "long", "text" and "binary".
    When the 'type' property is not specified the type will be deduced from the field name extension or automatically according to the content of the first item. When defining a 'binary' field type, it is not inferred from the data must be declared explicitly through the 'type' parameter.
    Please note that field's type cannot be changed after it contains data.
  • writeAccess - Specifies whether to allow unsigned requests to write into this field. The supported values are:
    • "serverOnly" (default ) - Only signed requests coming from the server are allowed.
    • "clientCreate" - Unsigned requests coming from the client are allowed to write into this field, only if it wasn't set before.
    • "clientModify" - Unsigned requests coming from the client are allowed to write into this field and modify existing values.
  • format - Allows assigning a regular expression that defines the format of this data field. Gigya will verify that data set in this data field matches the format. If the data set in this field doesn't match the format, Gigya will not set the data and will return an error. The best practice is to validate the data format on your client application. The format property accepts a string of the form: "regex('')". The regex syntax can be found in: Regular Expression Language Reference.
  • languages - An array of strings containing languages with which a text field is compatible, in addition to the default languages. A maximum of four such languages are supported. The values passed in this property are added to the existing languages in the field, and if the total number exceeds four languages, the operation fails.
    Note: The only language currently supported for this functionality is Japanese.

    encrypt - An encryption algorithm to use for encrypting data when writing in and reading from this field. Currently the only supported value is "AES". The binary data after hashing will be stored as a Base64 string. If set, data placed in this field is stored encrypted. When you retrieve the data, Gigya decrypts it (you receive the original data). Searches on encrypted data are limited to exact matches (such as x = 20); comparative searches (x > 20, x < 20 etc.) are not available. String search values are case sensitive.

    The only data Type fields that currently support encryption are:

    • string
    • text

    If you set the encrypt property on a field that already contains data, the existing data will remain un-encrypted. Only new data will be encrypted.

    Once a field is set to encrypt, it is not possible to remove encryption for that field.

To delete a field from the schema, you must ensure that data has never been saved to it (even if said data has been deleted), it has no defined type, and then set it to null (see "field6" in the example below). Saving data to a field automatically assigns a type.

Setting a field's properties to null will reset the writeAccess property to "serverOnly" (without deleting the field), if the field contains/contained data and/or has a type setting.

dynamicSchemaBooleanSpecifies whether the schema is strict or dynamic. The default value of this parameter is true i.e. dynamic schema. In a dynamic schema you may add new fields that are not defined in the schema to the DS. The new fields are automatically added to the dynamic schema. In a strict schema you can only write into fields that are already defined in the schema.

Schema Object Example

dataSchema: {
    unique: [                               
       ["field1"],                        // an example of a single field that must be unique
       ["field2", "field3" ]              // an example of a compound unique constraint based on two fields
    fields: {
        "field1": {
        "field4": {
        "field5": {
        "field6": null,     // Delete field6
        "field7": {
    dynamicSchema: false


Response Data

statusCode integer The HTTP response code of the operation. Code '200' indicates success.
errorCode integer The result code of the operation. Code '0' indicates success, any other number indicates failure. For a complete list of error codes, see the Error Codes table.
statusReason string A brief explanation of the status code.
errorMessage string A short textual description of an error, associated with the errorCode, for logging purposes. This field will appear in the response only in case of an error.
errorDetails string This field will appear in the response only in case of an error and will contain the exception info, if available.
callId string Unique identifier of the transaction, for debugging purposes.
time string The time of the response represented in ISO 8601 format, i.e., yyyy-mm-dd-Thh:MM:ss.SSSZ or
