Overview

Use the snapshot API to generate and retrieve file-based snapshots of all the entities within a campaign or all the performance reports by entity, for given advertiser, asynchronously. Processing time range for a snapshot request is up to 10-15 mins

WMC Measurement & Reporting Infra reprocesses data from the past three months on a daily basis, and data from the last six months on a weekly basis. Each time data is reprocessed for a given date, previously aggregated values may slightly change. The goal of this reprocessing is to capture any late-arriving data and ensure completeness.
Daily update is available around 10am PST

Note: 

• In cases of accounts with a substantial number of lines, the process of generating files might extend to as long as 60 minutes
• Snapshot IDs expire after 24 hours post generation
• Path is case sensitive across all the applicable URLs
• A single entity / report snapshot API request can retrieve data for a date range of up to 60 days within the past two years. To access the full two-year span, partners need to make multiple requests, each limited to a maximum of 60 days.
