Marketing agency — "Build a contact group from 3 WhatsApp groups, deduplicate, and blast a product launch announcement."

Restaurant chain — "Schedule a weekly report showing how many reservation confirmations were sent and delivered — send it to my WhatsApp every Monday morning."

2. At least one connected WhatsApp session (status: working)
3. Base URL: https://apiv2.waiflow.app/api/v2

Required API Key Scopes

Authentication

Every request must include one of:

Authorization: Bearer <jwt_token>

or

X-API-Key: <your_api_key>

Custom Groups

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

Create Custom Group

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

Bulk Send

Broadcast messages to a custom group with ban-safe throttling. Random 30s-2min delays between messages simulate human behavior.

Create Bulk Send Job

POST /bulk-send

{
  "session_id": "session-uuid-...",
  "custom_group_id": "custom-group-uuid-...",
  "message_content": "Special offer for our VIP clients!"
}

Response 201 Created:

{
  "id": "job-uuid-...",
  "session_id": "session-uuid-...",
  "custom_group_id": "custom-group-uuid-...",
  "status": "running",
  "total_recipients": 127,
  "sent_count": 0,
  "failed_count": 0,
  "created_at": "2026-02-12T10:00:00Z"
}

Stream Progress (SSE)

GET /bulk-send/{id}/progress

Returns Server-Sent Events with real-time updates:

data: {"sent": 45, "total": 127, "failed": 0, "status": "running"}
data: {"sent": 46, "total": 127, "failed": 0, "status": "running"}

Job Status Values

pending -> running -> completed / paused / cancelled / failed

Anti-Ban Safety

• Random 30s-2min delays between messages
• Typing simulation before each message
• Seen/read indicators marked automatically
• Burst rate limiting (4 msgs/2 min)

Scheduled Messages

Schedule one-time or recurring WhatsApp messages to custom groups with timezone support and full lifecycle control.

Create One-Time Schedule

POST /scheduled-messages

{
  "name": "Follow-up",

  "message_content": "Just checking in on your order!",
  "scheduled_time": "2026-02-15T09:00:00",
  "timezone": "Asia/Jerusalem"
}

{
  "name": "Weekly Update",
  "session_id": "session-uuid-...",
  "custom_group_id": "custom-group-uuid-...",
  "schedule_type": "cron",

  "created_at": "2026-02-12T10:00:00Z"
}

Schedule Types

• daily -- Every day (requires cron_expression)
• weekly -- Every week (requires cron_expression)
• monthly -- Every month (requires cron_expression)
• cron -- Custom cron expression (e.g., 0 9 * * MON-FRI)
