Things to know about automating Brex
API Rate Limits
Brex enforces 1,000 requests per 60 seconds per account, with additional limits of 1,000 transfers and 5,000 card creations per 24 hours. Exceeding these limits triggers HTTP 429 responses requiring exponential backoff delays.
Webhook Reliability
Only one webhook endpoint can be registered per customer, though it can listen to multiple event types. Brex uses Svix infrastructure with HMAC SHA-256 signature verification for security.
Authentication Types
User tokens expire after 30 days of inactivity while OAuth tokens expire after 1 hour and require refresh. OAuth access requires being a registered Brex partner through developer support.
High Volume Requirements
Payment automations exceeding 1,000 transactions per day require pre-approval from Brex developer support. Standard rate limits may be reduced further to prevent abuse.
Platform Support
Zapier offers pre-built Brex templates, while n8n requires HTTP Request nodes with generic authentication. Make, Power Automate, and Pipedream support Brex through their HTTP/API connectors.
Recent API Changes
The Budgets API v2 replaced the deprecated Spend Limits v1 API, and new AI-native Accounting API features enable two-way ERP data flow as of January 2026.
What breaks at scale
The 1,000 requests per 60-second limit becomes a serious bottleneck when syncing large transaction volumes or running frequent polling automations. You'll hit HTTP 429 errors that require exponential backoff delays, turning what should be real-time sync into hours-long batch jobs. Switch to webhooks and implement proper cursor-based pagination to avoid this wall.
Brex requires pre-approval from developer support for payment automations exceeding 1,000 transactions per day, and they may reduce your rate limits further to prevent abuse. Without approval, your payment processing automations will start failing silently or throwing rate limit errors during peak transaction periods.
Since Brex only allows one webhook endpoint per customer, high-frequency events can overwhelm your automation platform and cause webhook delivery failures. You'll need to build a webhook router that can handle multiple event types and distribute them appropriately, or risk losing critical financial data during webhook storms.
Frequently asked questions
Which automation platforms support Brex integrations?
Zapier provides native Brex connectors with pre-built templates, while Make, n8n, Power Automate, and Pipedream connect through HTTP/API nodes using Brex's REST API. All platforms can handle common workflows like syncing transactions to QuickBooks or creating Slack notifications for spending alerts.
What are Brex API rate limits for automation?
Brex limits API calls to 1,000 requests per 60 seconds per account, plus daily limits of 1,000 transfers and 5,000 card creations. High-volume automations exceeding 1,000 daily transactions need pre-approval from Brex support.
How do Brex webhooks work for real-time automation?
Brex supports one webhook endpoint per customer that can listen to multiple event types using Svix infrastructure. Webhooks use HMAC SHA-256 signatures for verification and are recommended over polling to avoid rate limits.
What Brex data can be automated to accounting systems?
Brex API provides access to transactions, card details, budgets, transfers, and user data that can be synced to QuickBooks, Xero, or NetSuite. The new AI-native Accounting API enables two-way data flow for advanced ERP integrations across all automation platforms.
