Introduction

Our APIs respond with data, errors, and meta/metadata blocks where appropriate. For example:

{entityId} are unique across all Retail Media entities
data and errors blocks may be contained in responses expected to return multiple entities
meta (or metadata) appears only for paginated responses

Response example

        },
 
        // ...
         
    ],
    "metadata": {
        "totalItemsAcrossAllPages": {numberOfEntities},
        "currentPageSize": {pageSize},
        "currentPageIndex": {pageIndex},
        "totalPages": {numberOfPages},
        "nextPage": "https://api.criteo.com/{endpoint}?pageIndex={pageIndex}&pageSize={pageSize}",

    }
}

Data Attributes

Attribute	Type	Description
`id`	string	Unique ID for the entity.`Entity IDs`are unique across all Retail Media entities
`type`	string	Type of entity
`attributes`	object	Entity attributes - may be omitted entirely if an entity does not have additional attributes

Error Attributes

Attribute	Type	Description
`traceId`	string	Unique ID for the error response
`type`	string	Type of error; machine-readable (e.g.`validation`)
`code`	string	Short machine-readable string for the error (e.g.`required-field`)
`instance`	string	URI referencing the endpoint that caused the error
`title`	string	Short human-readable string that summarizes the issue
`detail`	string	Human-readable explanation of the issue
`source`	object	Object referencing the field that caused the error

Pagination

Endpoints that retrieve all entities under a specific context supports pagination to navigate through all existing elements. Currently, there are two different formats to access the different pages that are based on different sets of query parameters and response blocks. Results are returned in ascending order by id Examples of endpoints:

List all Accounts associated with your API credentials
List all Brands associated with the Account
List all Retailers associated with the Account

offset & limit

Query Parameters	Type	Description
`offset`	integer	Defines the starting point from which records should be returned, i.e., will skip the first`offset`records (ordered by`id`) and return the subsequent ones; defaults to`0`if omitted
`limit`	integer	Specifies the maximum number of entities returned in a single page; defaults to`500`entities per page (if no other value is specified at endpoint-level)

Response example

{
    "data": [
        {
            "id": "{entityId}",
            "type": "{entityType}",
            "attributes": {
                "{fieldName}": {numericValue},
                "{fieldName}": "{stringValue}",
                // ...
            }
        },
        // ...
        
    ],
    "meta": {
        "count": {numberOfEntities},
        "offset": {offset},
        "limit": {limit}
    }
}

pageIndex & pageSize

Query Parameters	Type	Description
`pageIndex`	integer	Returns the specified page of results given a`pageSize`; pages are 0-indexed
`pageSize`	integer	Specifies the maximum number of entities returned in a single page; defaults to`25`entities per page

Response example

{
    "data": [
        {
            "id": "{entityId}",
            "type": "{entityType}",
            "attributes": {
                "{fieldName}": {numericValue},
                "{fieldName}": "{stringValue}",
                // ...
            }
        },
        // ...
        
    ],
    "metadata": {
        "totalItemsAcrossAllPages": {numberOfEntities},
        "currentPageSize": {pageSize},
        "currentPageIndex": {pageIndex},
        "totalPages": {numberOfPages},
        "nextPage": "https://api.criteo.com/{endpoint}?pageIndex={pageIndex}&pageSize={pageSize}",
        "previousPage": "https://api.criteo.com/{endpoint}?pageIndex={pageIndex}&pageSize={pageSize}"
    }
}

Filter by ID

All endpoints that retrieve all entities under a specific context supports an optional query parameter limitToId that can be used to retrieve the respective element. This param can also be combined multiple times to retrieve multiple elements at the same time. Examples:

Retrieve specific Account(s) from endpoint that lists all Accounts
Retrieve specific Brand(s) from endpoint that lists all Brands associated with the Account
Retrieve specific Retailer(s) from endpoint that lists all Retailers associated with the Account

Query Parameters	Type	Description
`limitToId`	integer	Limits results to the entity IDs specified; parameter key is repeated, e.g.`limitToId=1&limitToId=2`

Response example

{
    "data": [
        {
            "id": "1",
            "type": "{entityType}",
            "attributes": {
                "{fieldName}": {numericValue},
                "{fieldName}": "{stringValue}",
                // ...
            }
        },
        {
            "id": "2",
            "type": "{entityType}",
            "attributes": {
                "{fieldName}": {numericValue},
                "{fieldName}": "{stringValue}",
                // ...
            }
        },
        
    ],
    "meta": {
        "count": 2,
        "offset": 0,
        "limit": 500
    }
}

HTTP Response Codes

Response	Description
