Brex ACTION

Update Card Limit

Updates the spend limit on a vendor card (limit_type: CARD). This sends a complete spend_controls object, so treat it as a replacement: supply every spend control you want the card to keep, because Brex does not document whether omitted fields are preserved or cleared. Corporate cards draw on their cardholder's limit instead — use Set Limit for User for those. See the documentation

IMPLEMENTATION

Call this tool

Connect a user's Brex account once, then configure and run Update Card Limit from your backend or agent.

import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "brex-update-card-limit",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    brex: { authProvisionId: "apn_xxxxxxx" },
    cardId: "Card ID",
    amount: 10,
  },
})

console.log(result)

SCHEMA

Inputs

Pipedream supplies the connected account. Your application provides the operation-specific values below. Dynamic inputs are resolved against that user's account.

Update Card Limit inputs
Property Type Description
cardId Card ID string
The unique ID of the card. Use List Cards to find a card ID by cardholder, name, or last four digits.
Required
amount Spend Limit Amount integer
The new spend limit, in the currency's smallest denomination — 700 is $7.00 in USD.
Required
currency Spend Limit Currency string
The currency of the limit, in ISO 4217 format, e.g. USD. Defaults to USD when omitted, so set this explicitly for a card denominated in any other currency.
Optional
spendDuration Spend Duration string
How often the limit refreshes: MONTHLY, QUARTERLY, or YEARLY to refresh on that cadence, or ONE_TIME for a limit that never refreshes. Sent on every update, so set it to the cadence the card should have from now on — use Get Card to read the card's current duration first if you only mean to change the amount.
Required
reason Reason string
A free-text note explaining the new limit. Sent on every update, so re-supply the card's existing note if you want to keep it — use Get Card to read it first.
Optional
lockAfterDate Lock After Date string
Freeze the card automatically after this UTC date, in yyyy-mm-dd format. Sent on every update, so re-supply the card's existing lock date if you want to keep it — use Get Card to read it first.
Optional
