# Aggregate Member Account Balances

> This endpoint initiates an aggregation event for a `member`'s account balances.

This endpoint operates much like the [aggregate member endpoint](./aggregate-member) except that it gathers only account balance information; it does not gather any transaction data at all.

If an account balance aggregation is already running, a `202 Accepted` status will be returned. If another aggregation-type process is already running — like verification or extended transaction history — a `409 Conflict` will be returned.

Repeated calls to this endpoint for the same `member` can only be made at intervals greater than two hours. If made more frequently, a `429 Too Many Requests` status will be returned.

For more information on this and other aggregation-type processes, please see our [developer guide](/other/atrium).

<Warning>
  * Like **aggregate member**, calling this endpoint may result in multi-factor authentication. It is therefore important that the end user be present when initiating a balance request.
  * Balance jobs are limited to 5 requests every 2 hours.
</Warning>
