## Type declaration

### assertSessions()

> **assertSessions**: (`jids`, `force`?) => `Promise`\<`boolean`>

#### Parameters

##### jids

`string`\[]

### onBeforeSessionRefresh()?

> `optional` **onBeforeSessionRefresh**: (`jid`) => `void`

Invoked right before `assertSessions` is called for an existing-session identity change.
Used to kick off fire-and-forget side effects (e.g. tctoken re-issuance) in the same
order WA Web does — i.e. before the E2E session is re-established.
Must not throw; implementations are responsible for their own error handling.

#### Parameters

##### jid

`string`

#### Returns

`void`

### validateSession()

> **validateSession**: (`jid`) => `Promise`\<\{ `exists`: `boolean`; `reason`: `string`; }>

#### Parameters

##### jid

`string`

#### Returns

`Promise`\<\{ `exists`: `boolean`; `reason`: `string`; }>
