Retrieve messages by AI contact with pagination

Paginated message history, newest first. Prefer this over v2: page is 1-based and echoed back unchanged, page_size is configurable, and total/pages describe exactly what data contains — data.length never exceeds page_size, and summing data across all pages equals total. Unlike v2, the response contains only real messages: the synthetic “stage” and “interactive_note” entries that v2 injects are not messages and are not returned here. Also unlike v2, this endpoint is side-effect free: reading messages does NOT mark the conversation as read. Requesting a page beyond the last one returns an empty data with has_next_page: false.

Overview

Retrieve a contact’s messages with pagination, newest first. This is the recommended endpoint for reading message history. Use this instead of v2: page is 1-based and echoed back unchanged, page_size is configurable, and the counters describe exactly what you receive.

Authentication

Include your API key in the request header:

x-api-key: your_api_key_here

Path Parameters

Parameter	Type	Required	Description
`aiContactId`	string (UUID)	Yes	Unique identifier of the contact

Query Parameters

Parameter	Type	Required	Default	Description
`page`	number	No	`1`	Page number, 1-based. Page 1 = newest messages
`page_size`	number	No	`15`	Messages per page, between `1` and `100`

Both parameters must be integers. page below 1, page_size outside 1–100, and fractional values are rejected with 400.

Response Structure

Field	Type	Description
`data`	array	Messages for this page, ordered newest first
`page`	number	The page you requested, echoed back
`page_size`	number	The page size in effect
`pages`	number	Total number of pages. Valid values for `page` are `1..pages`
`total`	number	Total messages for this contact across all pages
`has_next_page`	boolean	Whether a page after this one exists

The counters are self-consistent: data never holds more than page_size items, and summing data across all pages equals total.

Message Object

This list is exhaustive and identical on every channel — the response carries these fields and nothing else:

Field	Type	Description
`id`	string	Message identifier, always a string (some channels store it as an integer internally)
`created_at`	string (ISO)	Message timestamp
`body`	string	Message text
`direction`	string	`inbound`, `outbound`, `internal_note`, `ai_note` or `task`
`type`	string	Channel message type, e.g. `text`, `image`, `audio`, `document`
`content`	object \| array \| null	Structured payload for non-text messages, as delivered by the channel. Channel-defined shape — WhatsApp template messages carry an array of components. Do not assume a fixed shape
`provider_message_id`	string \| null	Channel provider’s own message id
`attribution_id`	string \| null	Attribution identifier, when set
`user`	object \| null	Human sender (`first_name`, `last_name`) when sent by an agent
`assistant`	object \| null	AI sender (`id`, `name`) when sent by an assistant
`campaign`	object \| null	`{ title }` when the message came from a campaign
`ticket_id`	string \| null	Ticket this message belongs to, when there is one

v3 returns a fixed projection, so integrating once works for every channel. v2 instead returns the raw channel row — on WhatsApp that means the whole message record nested under whatsapp_message on top of the flattened fields, plus the ticket, summary and activity graph. If you depend on a field that only exists there, tell us and we will consider adding it to v3 rather than exposing the internal row.

Unlike v2, the response contains only real messages. The synthetic stage and interactive_note entries that v2 mixes into its list are not messages and are not returned here.

Example Request

curl --request GET \
  'https://api.vambe.me/api/public/contact/v3/df980fc8-b6db-4820-bf22-2969482d106d/messages?page=1&page_size=15' \
  --header 'x-api-key: your_api_key_here'

Example Response

{
  "data": [
    {
      "id": "9f1c2b3a-5d6e-4f70-8a91-2b3c4d5e6f70",
      "created_at": "2024-09-30T10:01:30.000Z",
      "body": "¡Por supuesto! ¿Cuál es tu número de pedido?",
      "direction": "outbound",
      "type": "text",
      "content": null,
      "provider_message_id": "wamid.HBgLNTY5MTIzNDU2NzgVAgARGBI5QTND",
      "attribution_id": null,
      "user": null,
      "assistant": {
        "id": "123e4567-e89b-12d3-a456-426614174000",
        "name": "Vambe"
      },
      "campaign": null,
      "ticket_id": "7c3e4f21-9b8a-4d5e-8f60-1a2b3c4d5e6f"
    },
    {
      "id": "6b0d8e1f-2a34-4c56-9d78-0e1f2a3b4c56",
      "created_at": "2024-09-30T10:00:00.000Z",
      "body": "Hola, necesito ayuda con mi pedido",
      "direction": "inbound",
      "type": "text",
      "content": null,
      "provider_message_id": "wamid.HBgLNTY5ODc2NTQzMjEVAgASGBQzQjJE",
      "attribution_id": null,
      "user": null,
      "assistant": null,
      "campaign": null,
      "ticket_id": "7c3e4f21-9b8a-4d5e-8f60-1a2b3c4d5e6f"
    }
  ],
  "page": 1,
  "page_size": 15,
  "pages": 9,
  "total": 127,
  "has_next_page": true
}

Fetching the Full History

const getAllMessages = async (contactId, apiKey) => {
  const all = [];
  let page = 1;

  while (true) {
    const response = await fetch(
      `https://api.vambe.me/api/public/contact/v3/${contactId}/messages?page=${page}&page_size=100`,
      { headers: { 'x-api-key': apiKey } },
    );

    const result = await response.json();
    all.push(...result.data);

    if (!result.has_next_page) {
      return all; // all.length === result.total
    }

    page += 1;
  }
};

Requesting a page past the last one is not an error: it returns an empty data with has_next_page: false.

Error Responses

Status Code	Description
400	Invalid `page` or `page_size`
401	Unauthorized — invalid or missing API key
404	Contact not found for this API key’s account
500	Internal Server Error

Important Notes

Order is newest first. Page 1 holds the most recent messages.
Reading is side-effect free. Unlike v2, fetching messages here does not mark the conversation as read, so polling this endpoint never changes what your agents see as unread.
Deleted Instagram messages are excluded from data, total and pages.
Cross-channel: works for every channel a contact may use.
