Frequently asked questions

Ceven connects to the Brex API to pull transaction data as soon as it is posted. The agent monitors the transaction stream and uses a set of mapping rules to categorize the spend. If a transaction lacks a receipt or a proper project code, the agent can reach out to the cardholder via email or Slack to request the missing info. This ensures that your accounting system is always up to date without requiring a manual export and import process at the end of the month. All data is mapped to your specific chart of accounts to maintain consistency.
Yes. You can build a workflow that triggers when a new employee is added to your HR software. Ceven will then call the Brex Create User and Create Card endpoints to provision their account and issue a card with a limit based on their job title or department. You can specify whether the card is physical or virtual and set the initial spend controls automatically. This removes the manual overhead for the finance team and ensures new hires have the tools they need on day one.
Ceven can be configured to monitor budget utilization in real time. By regularly calling the List Budgets and Get Budget Transactions endpoints, the agent tracks the burn rate against your set limits. When a budget hits a specific percentage, such as eighty percent, Ceven can alert the budget owner. If the budget is fully depleted, the agent can automatically update card limits to zero or notify the admin to request a budget increase, preventing unplanned overspend before it happens.
One specific quirk to be aware of is that Brex applies strict rate limits on their API endpoints to ensure platform stability. If a workflow attempts to pull thousands of transactions for many cards simultaneously, you may encounter a 429 Too Many Requests error. Ceven handles this by implementing an exponential backoff strategy, meaning the agent will automatically pause and retry the request after a short delay. While this ensures data integrity, very large bulk exports may take longer to complete than smaller, targeted queries.
Absolutely. Ceven simplifies the close process by pulling all transactions and comparing them against your bank deposits and accounting ledger. The agent identifies any gaps, such as missing receipts or uncategorized spend, and flags them for review. It can also generate a summary report of total spend by department and compare it to the forecasted budget. This transforms the month end close from a multi day manual project into a review process that takes a few minutes of human oversight.
Ceven uses industry standard encryption to protect all data in transit and at rest. Access to your Brex account is managed via secure tokens that are scoped to the minimum permissions required for your workflows to function. We do not store your primary login credentials. All API calls are logged in an audit trail so you can see exactly which agent accessed what data and when. You can revoke access at any time through the Brex admin dashboard, which immediately cuts off the connection.
Yes. You can create workflows that adjust card limits based on external triggers. For example, if a project is approved in your project management tool, Ceven can increase the limit on the assigned project card. Conversely, if a project is marked as complete, the agent can lower the limit or deactivate the card entirely. This allows for fine grained control over company spend without requiring a finance admin to manually log into the Brex dashboard for every minor adjustment.
Ceven can connect to multiple Brex entities if your organization operates across different legal entities or subsidiaries. You can set up separate connection profiles for each entity and build workflows that aggregate spend across all of them into a single master report. This is particularly useful for global companies that need a consolidated view of their cash position and spending patterns across different regions while still maintaining separate ledgers for local tax and compliance requirements.
