# caseMessages

query · in the family [Reading your records](/reference/reading-your-records/)

## What it does

One case’s message thread — staff replies, internal notes, and the customer’s messages.

ONE case's message thread, OLDEST-FIRST + born-paginated internal notes). caseId is the REQUIRED anchor (tenant-scoped — a cross-tenant/missing case refuses NOT_FOUND). 'nextToken' = the prior page's cursor, verbatim (opaque + case-bound; malformed/foreign → VALIDATION/INVALID). Requires authentication.

## What happens

Reads only.

| `limit` | [Int](/types/#scalars) | no | How many records to answer at most; a page may hold fewer. |
| `nextToken` | [String](/types/#scalars) | no | The cursor from the previous page, passed back exactly as received. |

## Returns

[CaseMessagePage](/types/CaseMessagePage/) `CaseMessagePage!` — One page of a case's thread.
