+| matchId | Match ID is an anonymous opaque unique identifier that represents a user on an advertiser’s system, like loyalty membership ID and order ID. With Match ID, advertisers can accurately track campaign performance without sharing customer data to Amazon like hashed email/phone while navigating complex customer journeys that spans multiple channels and devices. The advertisers implementing Amazon Advertising Tag (AAT) on their website can send match_id as an attribute along with the online events. Amazon matches this to users via cookies or hashed PII. When these users convert offline, advertisers can report it through Conversions API (CAPI) using the same match_id |

+#### I am an advertiser on Amazon Demand Side Platform. My agency cannot provide access to their entity as they manage other clients. How do I get access to a specific advertiser account?
+
+- **Option 1**: 
+1. Ask the agency to provide access to the specific advertiser account (where they wish to run your campaigns) within their agency. Events Manager must be given ‘View and Edit’ permission. Please see help article [here](https://advertising.amazon.com/help/G3ZZ6ZXQWG34DPPM){:target="_blank"}. 
+2. Use the Amazon Conversions API to send data to the specific account they have been given access to in step #1.
+- **Option 2**: [Not a supported pattern via Segment yet] Upload your data directly to Manager Account. You will see the data in Data Manager. You can then share the data from Data Manager to other advertiser accounts linked to the Manager Account.
