Supported syncing

Kevel replaces a segment’s membership in full on every import, so this destination always sends the complete audience. For more information about sync modes, refer to the sync modes docs.

​
Connect to Kevel

Kevel provides a pre-created S3 bucket for each Kevel Audience system. Configure a folder source in Kevel to import from that bucket, then point Hightouch at the same bucket.
  1. Go to the Destinations overview page and select Add destination.
  2. Select Kevel from the destination catalog.
  3. Enter the following, then select Continue:
    • AWS Credentials: Select or create AWS credentials with write access to the bucket.
    • Bucket name: The Kevel-provided S3 bucket for your Kevel Audience system, or your own bucket registered as a Kevel folder source.
Set up a folder source in Kevel pointing at this bucket so Kevel imports each file Hightouch uploads. Schedule the import, or configure it to run when new files are detected.

​
Sync configuration

​
Segment members

Each sync run uploads one CSV to the configured object key. The file begins with a segment-definition row that carries the segment’s metadata, followed by one row per member. The sync mode is All: every run writes the segment’s complete membership, which Kevel imports as a full replacement.

​
Configure record matching

Kevel matches members by exact identifier value and type, and never matches across types. Configure:
  • Identifier type — the type Kevel matches on. Hightouch writes it to the file’s userIdType column:
    • Email, Email (SHA-256), or Email (MD5)
    • Phone (E.164) or Phone (E.164, SHA-256)
    • Android advertising ID (GAID) or iOS advertising ID (IDFA)
    • CRM ID
  • Identifier column — the source column that holds the identifier value.

​
Configure identifier hashing

When you select a hashed identifier type (such as Email (SHA-256)), Hightouch asks whether to detect and hash your data:
  • Yes — Hightouch hashes the mapped column to the selected format and leaves values that are already hashed untouched.
  • No — your column already contains hashed values, so Hightouch sends them as-is.
Plaintext identifier types are always sent unchanged.

​
Describe the segment

Kevel creates the segment on first import and updates its metadata on later imports:

​
Set the object key

Set the object key (file path) in the bucket where Hightouch uploads the CSV, for example segments/high-value-customers.csv. You can include timestamp variables such as {YYYY}, {MM}, and {DD} in the path.

​
Tips and troubleshooting

To see the exact API requests and responses from each sync run, use the live debugger. To get notified by Slack, PagerDuty, SMS, or email when a sync fails, set up sync alerts. If you run into an issue this page doesn’t cover, .

​
Validate your setup

After your first sync completes, confirm the import in Kevel:
  • Check that the CSV landed at the configured object key in your bucket.
  • In Kevel, confirm the folder source imported the file and that the segment shows the expected member count. Files uploaded to the Kevel-provided bucket are deleted automatically after one month.
