Find the open source code for this destination in the GitHub repository.

RudderStack supports sending events to Snapchat Custom Audience via the following connection modes:

Connection ModeWebMobileServer
Device mode---
Cloud mode--Supported

Once you have confirmed that the source platform supports sending events to Snapchat Custom Audience, follow these steps:

  1. From your RudderStack dashboard, add the source. Then, from the list of destinations, select Snapchat Custom Audience.
  2. Assign a name to your destination and click Continue.

Connection settings

To successfully configure Snapchat Custom Audience as a destination, first authenticate your account by following the below steps:

  1. Click Create Account in the Account Settings section.
  2. From the modal, click the Sign in with Google button.
  3. Choose the required account and grant RudderStack the required permissions.
  4. Click Save to use the specified account:
Google Account authentication

In case you have authenticated multiple accounts, you can click Edit Credentials to select/delete any other authenticated account:

Google Account authentication

RudderStack gives an error if you try to delete an account used by any other connection set up for the same destination.

Next, configure the following settings:

  • Segment ID: Enter your Snapchat segment ID. For more information on getting your segment ID, refer to the FAQ section below.
  • Schema: Select the schema (EMAIL, MOBILE AD ID, or PHONE) from the dropdown.
The corresponding field (email, phone, or mobileAdId/mobile_id) must be present in your events. Otherwise, RudderStack will not send the events to Snapchat Custom Audience.
  • Disable hashing: By default, RudderStack hashes the email, phone, and mobileAdId in the SHA-256 format. If enabled, RudderStack will not perform the hashing.
If you enable this setting, make sure you normalize and SHA-256 hash your identifiers before sending the data to RudderStack.

Schema fields mapping

The following table details the mapping of the schema fields (as specified in the RudderStack dashboard) and the Snapchat Marketing API.

RudderStack normalizes the raw identifiers by following the Snapchat-prescribed rules before SHA-256 hashing and sending them to Custom Audience.

RudderStack groups the identifiers in batches with a maximum of 100000 identifiers per request. For more information, refer to the Snapchat Marketing API.
RudderStack schema fieldCustom Audience fieldNotes[sha256(email)]RudderStack trims any leading and trailing whitespaces and converts all characters into the lower case before hashing.[sha256(phone)][sha256(mobile)]
RudderStack includes the country code and removes any double 0s in front of it. It also excludes any non-numeric characters like whitespaces, parentheses, +, or -.


RudderStack converts all characters into the lower case. It does not remove any hyphens.
email, mobileAdId/mobile_id, or mobile must be present in your events depending on the Schema setting configured in the RudderStack dashboard. Otherwise, RudderStack will not send the events to Snapchat Custom Audience.
