Audiences

Add People

Adds users from a new CSV file to an existing uploaded custom audience. The file uses the audience's saved column mapping, processing happens in the background, and existing audience members remain unchanged.

post/audiences/{id}/add_people

Path parameters

idstring required

Audience ID, prefixed adaud_.

Headers

Idempotency-Keystring
Example:d9105228-4a08-46b1-8b91-42fed586d383

A unique key that makes this request safe to retry. See Idempotent requests.

Request body

file_idstring required

The new customer CSV — a file id (file_...) returned by POST /files. Its headers must match the audience's saved column mapping.

Example request

{
  "file_id": "file_xxxxxxxxxxxxxx"
}

Response

Audience upload accepted.

audience_type'custom' | 'lookalike' required

Whether the audience targets a defined group of people or people similar to an existing audience.

auto_refreshboolean required

Whether Whop rebuilds membership from saved People filters twice a day. When false, People audiences keep the members matched at creation. Always false for uploaded lists, lookalikes, and engagement audiences. Engagement membership is maintained by Meta.

created_atstring required

When the audience was created, as an ISO 8601 timestamp.

error_messagestring nullable required

Processing error message. null unless processing is partial or failed.

filtersobject nullable required

Saved Whop People filters that define membership, using the same keys as GET /people. null for uploaded lists, engagement audiences, and lookalikes.

idstring required

Audience ID, prefixed adaud_.

last_refreshed_atstring nullable required

When the audience membership was last rebuilt, as an ISO 8601 timestamp. null until the first build completes.

lookalike_rationumber nullable required

For lookalikes: the upper bound of the similarity band as a fraction (0.02 = top 2%). null for custom audiences.

lookalike_starting_rationumber nullable required

For lookalikes: the lower bound of the similarity band as a fraction. null for custom audiences and first-tier lookalikes.

matched_rowsnumber required

Members successfully uploaded to connected ad accounts. Always 0 for lookalikes and engagement audiences.

namestring required

Audience display name.

platform_audience_idsstring[] required
processed_rowsnumber required

Members processed from the source so far. Always 0 for lookalikes and engagement audiences.

progress_percentnumber required

Processing progress from 0 to 100.

source_audience_idstring nullable required

For lookalikes: the audience this lookalike was built from. null for custom audiences.

source_type'csv_upload' | 'people_filter' | 'engagement' required

Membership source: an uploaded CSV, Whop People filters, or social engagement.

status'pending' | 'processing' | 'syncing' | 'ready' | 'partial' | 'failed' required

Current state of audience creation. For engagement audiences, ready means the rules were created on Meta; membership may still be populating. syncing means Whop is sending matched rows to connected ad accounts. When status is partial or failed, error_message explains what went wrong.

total_rowsnumber required

Total members detected in the source — CSV rows for uploaded lists, matching people for automatic audiences. Always 0 for lookalikes and engagement audiences.

updated_atstring required

When the audience was last updated, as an ISO 8601 timestamp.
