POST /identity/map

Map multiple email addresses, phone numbers, or their respective hashes to their raw UID2s and salt bucket IDs.

Used by: This endpoint is used mainly by advertisers and data providers. For details, see Advertiser/Data Provider Integration Guide.

Batch Size and Request Parallelization Requirements

Here's what you need to know:

• The maximum request size is 1MB.
• To map a large number of email addresses, phone numbers, or their respective hashes, send them in sequential batches with a maximum batch size of 5,000 items per batch.
• Unless you are using a private operator, do not send batches in parallel. In other words, use a single HTTP connection and map directly identifying information (DII) consecutively.
• Be sure to store mappings of email addresses, phone numbers, or their respective hashes.
  Not storing mappings may increase processing time drastically when you have to map millions of emails addresses or phone numbers. Recalculating only those mappings that actually need to be updated, however, reduces the total processing time because only about 1/365th of raw UID2s need to be updated daily. See also Advertiser/Data Provider Integration Guide and FAQs for Advertisers and Data Providers.

IMPORTANT: You must encrypt all request using your secret. For details and Python script examples, see Encrypting Requests and Decrypting Responses.

Path Parameters

Path Parameter	Data Type	Attribute	Description
{environment}	string	Required	Testing environment: https://operator-integ.uidapi.com Production environment: https://prod.uidapi.com For a full list, including regional operators, see Environments.

Unencrypted JSON Body Parameters

IMPORTANT: You must include only one of the following four conditional parameters, plus the required optout_check parameter with a value of 1, as key-value pairs in the JSON body of the request when encrypting it.

Body Parameter	Data Type	Attribute	Description
email	string array	Conditionally Required	The list of email addresses to be mapped.
email_hash	string array	Conditionally Required	The list of Base64-encoded SHA-256 hashes of normalized email addresses to be mapped.
phone	string array	Conditionally Required	The list of normalized phone numbers to be mapped.
phone_hash	string array	Conditionally Required	The list of Base64-encoded SHA-256 hashes of normalized phone numbers to be mapped.
optout_check	integer	Required	Checks whether the user has opted out. Include this parameter with a value of 1.

Request Examples

The following are unencrypted JSON request body examples for each parameter, one of which you should include in your identity mapping requests:

{
    "email":[
        "user@example.com",
        "user2@example.com"
    ],
    "optout_check":1 
}

{
    "email_hash":[
        "eVvLS/Vg+YZ6+z3i0NOpSXYyQAfEXqCZ7BTpAjFUBUc=",
        "tMmiiTI7IaAcPpQPFQ65uMVCWH8av9jw4cwf/F5HVRQ="
    ],
    "optout_check":1    
}

{
    "phone":[
        "+1111111111",
        "+2222222222"
    ],
    "optout_check":1 
}

{
    "phone_hash":[
        "eVvLS/Vg+YZ6+z3i0NOpSXYyQAfEXqCZ7BTpAjFUBUc=",
        "tMmiiTI7IaAcPpQPFQ65uMVCWH8av9jw4cwf/F5HVRQ="
    ],
    "optout_check":1   
}

Here's an encrypted identity mapping request example for a phone number:

echo '{"phone": ["+1111111111", "+2222222222"],"optout_check":1}' | python3 uid2_request.py https://prod.uidapi.com/v2/identity/map YourTokenBV3tua4BXNw+HVUFpxLlGy8nWN6mtgMlIk= DELPabG/hsJsZk4Xm9Xr10Wb8qoKarg4ochUdY9e+Ow=

Decrypted JSON Response Format

NOTE: The responses are encrypted only if the HTTP status code is 200. Otherwise, the response is not encrypted.

A successful decrypted response returns the raw UID2s and salt bucket IDs for the specified email addresses, phone numbers, or their respective hashes.

{
    "body":{
        "mapped": [
            {
                "identifier": "eVvLS/Vg+YZ6+z3i0NOpSXYyQAfEXqCZ7BTpAjFUBUc=",
                "advertising_id": "AdvIvSiaum0P5s3X/7X8h8sz+OhF2IG8DNbEnkWSbYM=",
                "bucket_id": "a30od4mNRd"
            },
            {
                "identifier": "tMmiiTI7IaAcPpQPFQ65uMVCWH8av9jw4cwf/F5HVRQ=",
                "advertising_id": "IbW4n6LIvtDj/8fCESlU0QG9K/fH63UdcTkJpAG8fIQ=",
                "bucket_id": "ad1ANEmVZ"
            }
        ]
    },
    "status":"success"
}

If some identifiers are considered invalid, they are included in the response in an "unmapped" list. In this case, the response status is still "success". If all identifiers are mapped, the "unmapped" list is not included in the response.

{
    "body":{
        "mapped": [
            {
                "identifier": "eVvLS/Vg+YZ6+z3i0NOpSXYyQAfEXqCZ7BTpAjFUBUc=",
                "advertising_id": "AdvIvSiaum0P5s3X/7X8h8sz+OhF2IG8DNbEnkWSbYM=",
                "bucket_id": "a30od4mNRd"
            }
        ],
        "unmapped": [
            {
                "identifier": "some@malformed@email@hash",
                "reason": "invalid identifier"
            }
        ]
    },
    "status":"success"
}

If some identifiers have opted out from the UID2 ecosystem, the opted-out identifiers are moved to the "unmapped" list along with any invalid identifiers found. In this case, the response status is still "success".

{
    "body":{
        "mapped": [
            {
                "identifier": "eVvLS/Vg+YZ6+z3i0NOpSXYyQAfEXqCZ7BTpAjFUBUc=",
                "advertising_id": "AdvIvSiaum0P5s3X/7X8h8sz+OhF2IG8DNbEnkWSbYM=",
                "bucket_id": "a30od4mNRd"
            }
        ],
        "unmapped": [
            {
                "identifier": "tMmiiTI7IaAcPpQPFQ65uMVCWH8av9jw4cwf/F5HVRQ=",
                "reason": "optout"
            }
        ]
    },
    "status":"success"
}
