# Get Conversation Messages

> Read messages for a conversation and its required sender account.

Requires `inbox:read`. **`accountId` is required**, in addition to the conversation ID in the path. Use the SendPilot sender account from the conversation list.

`limit` defaults to 50 with a maximum of 100. Pass `continuationToken` unchanged to page through results.

Inspect the conversation before retrying a send that returned `DELIVERY_UNCONFIRMED` or `UPSTREAM_TIMEOUT`. The original message may have been delivered.


## OpenAPI

````yaml GET /v1/inbox/conversations/{conversationId}/messages
openapi: 3.0.0
info:
  title: SendPilot External API
  description: >

    # SendPilot External API v1


    Public API for integrating with SendPilot programmatically.


    ## Authentication


    Requests authenticate with a workspace API key in the `X-API-Key` header:


    ```

    X-API-Key: sp_live_your_api_key_here

    ```


    `Authorization: Bearer sp_live_...` (or `sp_test_...`) is also accepted.
    Prefer one header; `X-API-Key` takes precedence. Clerk OAuth tokens for MCP
    connection URLs are not public REST API keys.


    A key only reaches what its scopes and creator's current workspace
    permissions allow. Each operation lists the scopes it needs in
    `x-sp-scopes`. Use `GET /v1/me` to inspect the effective permissions and
    subscription state.


    ## Rate Limits


    - **Per API Key**: 300 requests/minute

    - **Per Workspace**: 50,000 requests/day


    Responses that reach the rate limiter include these headers; early
    authentication failures may not:

    - `X-RateLimit-Limit`: Max requests per minute

    - `X-RateLimit-Remaining`: Remaining requests in current window

    - `X-RateLimit-Reset`: Epoch timestamp when limit resets


    ## LinkedIn Sender Limits


    When using messaging endpoints, these headers show account limits:

    - `X-LinkedIn-Messages-Remaining`: Messages left today

    - `X-LinkedIn-Connections-Remaining`: Connection requests left today

    - `X-LinkedIn-Quota-Reset-At`: When daily limits reset


    ## Retries


    Send an `Idempotency-Key` header on POST and PATCH requests. A retry with
    the same key within 24 hours returns the first result (with
    `Idempotent-Replayed: true`) instead of acting twice. The same key with a
    different request answers 422 `IDEMPOTENCY_KEY_REUSED`; a retry while the
    first request still runs answers 409 `IDEMPOTENCY_IN_PROGRESS`.


    Once execution is attempted, its response (including errors) is retained. If
    a process stops or result storage fails after the attempt, the durable
    record blocks another execution for the replay window and returns 409
    `IDEMPOTENCY_IN_PROGRESS` or `IDEMPOTENCY_REPLAY_UNAVAILABLE`. Check the
    operation's status before using a new key: an uncertain outcome may already
    have acted. Requests refused before execution is claimed, such as
    authentication or rate-limit refusals, can be retried with the same key.


    ## Webhooks


    Configure webhooks in the SendPilot app to receive real-time events:

    - `lead.tag.updated`

    - `lead.updated`

    - `message.sent`

    - `reply.received`

    - `connection_request.sent`

    - `connection_request.accepted`

    - `campaign.started`

    - `campaign.paused`

    - `campaign.resumed`

    - `campaign.finished`


    ## Error Codes


    Errors return a JSON body. Use the machine-readable `code` when supplied;
    validation messages can be arrays, and some legacy errors omit `code`. A
    typical error is:

    ```json

    {
      "statusCode": 400,
      "error": "Bad Request",
      "code": "SPECIFIC_ERROR_CODE",
      "message": "Human-readable description"
    }

    ```
