# Update thread attributes

<Snippet file="graphql/sdk-note.mdx" />

The mutations below change individual attributes on an existing thread. Each one operates on a single field — there is no general-purpose `updateThread` mutation, so to change multiple attributes you call multiple mutations.

These operations require the following permissions:

* `thread:edit`

## Change thread title

<Snippet file="graphql/update-thread-title.mdx" />

## Change thread priority

Priority is an integer from `0` (urgent) to `3` (low).

<Snippet file="graphql/change-thread-priority.mdx" />

## Change the thread's customer

Reassigns the thread to a different customer in your workspace. The original customer keeps any other threads they have.

<Snippet file="graphql/change-thread-customer.mdx" />

## Change the thread's tenant

Move the thread to a different tenant (or pass `tenantIdentifier: null` to detach the thread from its current tenant).

<Snippet file="graphql/update-thread-tenant.mdx" />

## Change the thread's tier

Move the thread to a different tier (or pass `tierIdentifier: null` to detach).

<Snippet file="graphql/update-thread-tier.mdx" />
