File drop activations are accumulated in the CDP and periodically written in a compressed file in an S3 Bucket in the AWS account that hosts the CDP. The files are named using the timestamp at which they were written, such as 2020-01-01_23-45.gz.
Each file drop activation has its own bucket prefix, identified by the activation key. Third parties that consume these file-based activations should be have read access to the S3 bucket prefix.
If a cookie synchronization URL is set, whenever an activation request is received from a browser for an activation container that triggers this data receiver, the cookie synchronization process is automatically triggered. Cookie syn requests can be issues from the javascript tag or directly using an HTTP request as follows:
