Replace audience members

PUT /v1/admin/email/audiences/{id}/members

• Operation ID: setEmailAudienceMembers
• Tags: Email audiences
• Base URL: http://localhost:8787

Replaces the member list with either members (emails and/or user ids) or a pasted csv (first column; optional email header). Duplicates are removed case-insensitively; at most 50,000 members. Invalid CSV rows return 400 validation_failed with invalid_emails and invalid_count in details.

Workflow: Integration guide.

Authentication: staff Bearer JWT with permission email.write.

Authentication

• Auth: staff Bearer JWT (Authorization: Bearer <access_token>) with the permissions below.
