This maps to GrowthLoop Audiences and Journeys:

Use it for	Audiences	Journeys
Sending GrowthLoop audiences as Reddit custom audiences	✓	✓

To send conversion events, use Reddit Ads Conversions. Do not use an audience export to send conversion events.

Prerequisites

Make sure you have:

A Reddit Ads account. See Reddit's ads registration if you need one.
Custom Audience API access on that account. If you cannot upload custom audiences, ask your Reddit representative to enable it.
The Ad Account ID that should receive audiences. In Business Manager, open Assets → Ad Accounts. IDs start with a2_.

Set up Reddit Ads as a destination

In GrowthLoop, click the Destinations tab on the left sidebar.
Click New Destination in the top right corner.
Search for Reddit Ads and click Add Reddit Ads.
Sign in to Reddit and click Allow to grant GrowthLoop access.
Enter the required information, then click Create.

Field	Description
Destination Name	Name this destination in GrowthLoop. Use a name so your team recognizes its purpose, like "Reddit Ads".
Sync Frequency	Set the default export frequency (for example, daily or weekly). You can override this setting for individual exports.
Business Account	Business linked to your Reddit login. Choose the business that owns the ad account.
Ad Account	Ad account ID that should receive custom audiences. Starts with `a2_`.

GrowthLoop validates the connection. Reddit Ads then appears in your list of connected destinations.

Export to Reddit Ads

From within GrowthLoop, export from an audience or from a journey Destination Node. See Export an audience or Build a journey if you need more information on these steps.

After building or selecting an audience, click Export, then search for Reddit Ads. In a journey, add a Destination Node under Ads and select Reddit Ads.

Map identifiers

On an audience or in a journey Destination Node, map Email address or Mobile Ad ID (MAID). Map at least one.

Email address	No	Email address. GrowthLoop hashes it as SHA-256
Mobile Ad ID (MAID)	No	Mobile advertising ID. GrowthLoop hashes it as SHA-256

This destination does not send additional personalization fields.

Configure the export

This is where you set the campaign type and schedule for audience exports. On a journey Destination Node, you set timing on the journey canvas.

Setting	Audience export	Journey Destination Node
Export Name	Defaults to `{audience name}_GL_Audience_{audience ID}`. That is the custom audience name unless you change it.	Required. Enter a name so you can find the export in GrowthLoop and the audience in Reddit Ads.
Custom Audience Status	New (default) creates a custom audience. Existing adds contacts to a custom audience you choose.	Journeys create or reuse the audience for this export.
Select Custom Audience	Required when Custom Audience Status is Existing. Choose a custom audience from the list.	Journeys do not pick an existing custom audience.
Campaign type	Choose a one-time or ongoing export.	The journey schedule controls when the journey runs and contacts are sent to Reddit Ads.
Export Inclusion Criteria	All audience members for a full refresh, or Newly added audience members for additions and removals since the last export.	The journey sends contacts who reach this node.
Schedule	Set frequency, start date, end date, and days of the week for ongoing exports.	Users reach this node when the journey runs. Add a Delay Node or set Criteria Evaluation to control timing.

Export behavior

This is what GrowthLoop writes when you export an audience.

Behavior	What happens
What GrowthLoop writes	A Reddit custom audience of type customer list. Direction is GrowthLoop → Reddit Ads.
When it runs	GrowthLoop sends the export as a batch on the next successful run. An export that starts Now runs within about 15 minutes. Journeys send exports on demand when users reach the Destination Node.
Audience	New creates a custom audience named after the export. Existing writes to the custom audience you selected. Later runs reuse the stored audience.
Match field	Email address or MAID, hashed as SHA-256.
Adds	GrowthLoop adds hashed identifiers to the custom audience.
One-time exports	GrowthLoop sends current membership once, or the additions and removals since the last export if you chose that inclusion setting.
Ongoing adds and removals	Ongoing exports add contacts who enter the audience and remove those who leave that custom audience.
Deletes	GrowthLoop does not delete the Reddit custom audience.

Confirm the export was successful

When the run finishes, confirm you can use the data in Reddit Ads.

Audience export: Open Audience Manager and look up the _GL_Audience_ name unless you changed Export Name or exported to an existing custom audience.
Journey Destination Node: Open Audience Manager and look up the custom audience named after the export.

In GrowthLoop, review counts on the audience Exports tab, or open the Activity tab on the journey Destination Node. See Export an audience or Monitor a journey for more information.

Congrats on successfully exporting to Reddit Ads!
