Name and Content Requirements for ID Synchronization Files
Describes the required fields, syntax, and naming conventions used for file-based ID synchronization. Name and organize your file contents according to these specifications.
monospaced text, italics, brackets [ ] ( ), etc.) in this document indicate code elements and options. See Style Conventions for Code and Text Elements for more information.File Name Syntax and Examples
ID file names contain the following required and optional elements:
[adobe_id_] [c2c_id_]MASTERDPID_DPID[_DPID]_TIMESTAMP.sync[.SPLIT_NUMBER][.gz]
adobe_idc2c_idMASTERDPIDThe master data provider ID is the parent ID of the DPIDs in the file name. Also, the first user ID in the data file corresponds to the master ID. The subsequent DPIDs are other identifiers that belong to the master. Synchronization maps DPIDs in the file name to UUIDs in the file.
This DPID must only contain device IDs, such as AAM UUID, GAID, IDFA, and so on. It cannot contain DPUUIDs. Doing so can result in incorrect synchronization.
DPIDData provider IDs. These IDs represent entities or data sources associated with the master DPID. Synchronization maps DPIDs in the file name to UUIDs in the file.
The number of DPIDs in the file name must match the number of UUIDs in the data file. For example, say your file name contains a master DPID and 3 DPIDs. Your data file must include 4 corresponding columns of UUIDs, formatted as described in the file content section below.
timestamp.sync[.SPLIT_NUMBER][.gz]File Name Examples
The following examples show properly formatted files names. Your file names could look similar.
adobe_id_111_222_333_444_1454442149.syncadobe_id_123_898_456_1454442149.sync.1.gzadobe_id_123_898_456_1454442149.sync.2.gzc2c_id_123_898_1454442149.sync.gz
File Content Syntax and Examples
The contents of an ID file include the following elements:
UUID <tab>UUID <tab>UUID<tab> UUID
The file contains user IDs (UUID). In each row, separate the IDs with a tab. The following example shows a properly formatted ID file. Your contents could look similar.
abc123 def456 ghi789 xyz987
File Content Considerations
When creating your inbound files, make sure the first column is only populated with device IDs, such as AAM UUID, GAID, IDFA, and so on. See Index of IDs in Audience Manager for a detailed explanation of IDs supported by Audience Manager.
Synchronization Matches DPUUIDs to UUIDs
The purpose of an ID sync file is to sync the DPUUIDs from your own Data Sources with Audience Manager UUIDs. Synchronization maps the DPUUIDs from the master DPID and its related DPIDs to the Audience Manager UUIDs. Where you put the IDs in the file name and body determines how these identifiers are mapped to each other. For example, take the two sample files shown here:
-
File 1:
adobe_id_0_12345_1476312152.sync -
File 2:
adobe_id_12345_67890_1476312876.sync
Given the sample name and contents, the IDs map together like this:
File 1 ( Download sample file)
Step 1: the ID sync process will sync the DPUUIDs from DPID 12345 with the Audience Manager UUIDs in the left column. Note that the DPID “0” in the file name represents Audience Manager UUIDs.
File 2 ( Download sample file)
Step 2: the DPUUIDs from DPID 12345 have been synced in step 1 with the Audience Manager UUIDs. What this ID sync will do is sync the DPUUIDs from DPID 67890 with the Audience Manager UUIDs from step 1.
Other Format Requirements
User IDs cannot:
- Have tabs in the ID itself. Tabs are used only to separate individual IDs in the data file.
- Contain personally identifiable information (PII).
- Use URL encoding. Pass in unencoded IDs only.
Any rows that end with tabs or spaces will not be processed or realized. As a rule, make sure you keep the end of the rows clear.
