Custom Groups

Build targeted contact lists for Bulk Send and Scheduled Messages. Custom Groups are MoltFlow contact lists -- not WhatsApp groups.

Method	Endpoint	Description
GET	/custom-groups	List all custom groups
POST	/custom-groups	Create group (with optional initial members)
GET	/custom-groups/contacts	List all unique contacts across sessions
GET	/custom-groups/wa-groups	List WhatsApp groups for import
POST	/custom-groups/from-wa-groups	Create group by importing WA group members

POST /custom-groups

{
  "name": "VIP Clients",
  "members": [
    {"phone": "+15550123456"},
    {"phone": "+15550987654", "name": "Jane Doe"}
  ]
}

Members is an array of objects with phone (required) and name (optional). Omit members to create an empty group.

Create Group from WhatsApp Groups

POST /custom-groups/from-wa-groups

{
  "name": "Imported Leads",
  "wa_groups": [
    {"wa_group_id": "120363012345@g.us", "session_id": "session-uuid-..."},
    {"wa_group_id": "120363067890@g.us", "session_id": "session-uuid-..."}
  ]
}

Resolves participants from each WhatsApp group, deduplicates by phone number, and creates the custom group with all unique members.

List WhatsApp Groups

GET /custom-groups/wa-groups

Returns all WhatsApp groups across your connected sessions with participant counts. Use this to discover groups available for import.

Response 201 Created:

{
  "id": "group-uuid-...",
  "name": "VIP Clients",
  "member_count": 2,
  "created_at": "2026-02-12T10:00:00Z"

Add Members

POST /custom-groups/{id}/members/add

  "contacts": [
    {"phone": "+15551112222"},
    {"phone": "+15553334444", "name": "Bob Smith"}
  ]
}

Each contact is an object with phone (required) and name (optional). Max 1,000 per request. Duplicates are silently skipped.

Export Members

GET /custom-groups/{id}/export/csv -- Returns CSV download GET /custom-groups/{id}/export/json -- Returns JSON array
