Configuration

Setting	Type	Required	Description

`accountId`	`string`	Yes (List Cash Transactions only)	ID of the cash account to retrieve transactions for

Outputs

Field	Type	Description
`data`	`json`	Array of result objects (cash account objects, transaction objects, or user objects depending on the operation)
`metadata`	`json`	Response metadata containing `count` (number of items returned) and `next_cursor` (cursor string for the next page, or `null` if there are no more pages)
`metadata.count`	`number`	Number of items returned in this response
`metadata.next_cursor`	`string`	Cursor to pass as `cursor` in the next request to retrieve the following page of results; `null` when all results have been returned

Example

[Starter] → [Brex: List Cash Transactions] → [Agent: Summarize spend]

Set {{BREX_API_KEY}} as the user token, then pass the account ID from a previous List Cash Accounts call as {{listAccounts.data[0].id}}. Optionally scope transactions to the current month with postedAtStart set to {{function.result.monthStart}}. The Agent block then receives {{brex.data}} and produces a plain-language spend summary.

Tips

Generate your token in the Brex dashboard under Settings → Developer → User Tokens. Tokens are scoped to the user who creates them; use a service account token for production workflows.
Paginate large result sets by checking {{brex.metadata.next_cursor}} — if it is not null, feed it back into the cursor input on a subsequent run or loop iteration to retrieve the next page.
Use List Cash Accounts first when the account ID is unknown — chain it before List Cash Transactions and reference the returned account ID with {{listAccounts.data[0].id}}.
Date filtering (postedAtStart) accepts ISO 8601 format with or without a time component: 2026-01-01 and 2026-01-01T00:00:00Z are both valid. Use a Function block to compute dynamic date strings if needed.
