MNTN Audience Connector Setup Guide

The MNTN Audience connector lets you create and manage MNTN audience segments from Tealium. Use this connector to sync first-party identities in batches to add, update, or remove audience members for connected TV (CTV) targeting, retargeting, and suppression without manual file uploads or custom API code.

Batch Upsert Audience Members

Batch limits

This action uses batched requests to support high-volume data transfers to the vendor. Parallel processing may result in events reaching the vendor out of sequence. Add a sequence value to events if ordering is important. For more information, see Batched Actions. Requests are queued until one of the following thresholds is met or the profile is published:

Max number of requests: 10,000
Max time since oldest request: 60 minutes
Max size of requests: 2 MB

Parameters

Parameter	Description
Segment ID	ID of the existing MNTN audience segment to insert or update identities in.
Identity ID	(Required) Unique ID for the audience member within the segment (for example, a Tealium Visitor ID or CRM ID).

Identifiers

Parameter	Description
Email (Apply SHA256)	Plain text email address. The connector normalizes (lowercase, trim) and applies SHA256 hashing.
Email (Already SHA256)	Pre-hashed email address. Ensure the value is lowercased and trimmed before hashing.
Phone (Apply SHA256)	Plain text phone number. The connector strips non-digits, prepends the country code, and applies SHA256 hashing.
Phone (Already SHA256)	Pre-hashed phone number. Remove non-digits and prepend `1` for 10-digit US numbers before hashing.
IPv4	Raw IPv4 address.
IPv4 (Already SHA256)	Pre-hashed IPv4 address.
IPv6	Raw IPv6 address.
IPv6 (Already SHA256)	Pre-hashed IPv6 address.
MAID	Raw mobile advertising ID in UUID format, used for CTV or mobile targeting (for example, `3f097372-f01e-4b64-984c-395ae5828ee6`).

IPv4 (Already SHA256), IPv6, IPv6 (Already SHA256), and MAID have selective support in MNTN campaign targeting. Contact your MNTN account team before relying on these identifiers for targeting.

Batch Remove Audience Members

Batch limits

Max number of requests: 1,000
Max time since oldest request: 60 minutes
Max size of requests: 2 MB

Parameters

Parameter	Description
Audience Segment	Select the MNTN audience segment to remove members from, or enter a segment ID manually.
Identity ID	(Required) The identity ID of the audience member to remove from the segment (for example, a Tealium Visitor ID or CRM ID).

Best practices

Start with a small test segment before you scale to production volumes.
Keep request payloads efficient. MNTN recommends targeting batches around 2 MB and staying below the 8 MB maximum request size.
Use a consistent identity strategy to avoid duplicate or conflicting records.
Confirm consent and privacy requirements before you send identifiers to MNTN.
