Community FAQ
Questions by product
Airbase FAQ
Does Airbase support self-hosting or is it fully SaaS only?
Airbase is a fully cloud-based SaaS platform and does not offer a self-hosted deployment option. All data and workflows are managed within their secure cloud environment, which simplifies maintenance but means you rely on their infrastructure and uptime.
Community insight informed by Reddit discussions
Can Airbase function offline or handle expense approvals without internet connectivity?
Airbase requires internet connectivity to process transactions, approvals, and sync data. There is no offline mode; all approvals and spend management workflows happen in real time through their web or mobile apps connected to the cloud.
Community insight informed by Hacker News discussions
What are the data ownership and export capabilities in Airbase for compliance audits?
Airbase retains ownership of your transactional and approval data within their platform but provides export options in CSV and PDF formats for audit and compliance purposes. However, full raw database exports or direct data ownership transfers are not supported.
Community insight informed by StackOverflow discussions
Are there any limitations or rate limits on Airbase's API for integrating with ERP systems?
Airbase offers APIs primarily focused on spend data and approvals integration, but they enforce rate limits to ensure platform stability. Detailed API documentation notes limits around 1000 requests per minute, which is sufficient for typical mid-market finance workflows but may require batching for high-volume automation.
Community insight informed by Forums discussions
What migration or export paths exist if we want to switch from Airbase to another accounts payable platform?
Airbase supports exporting your spend, card transactions, and approval history in standard CSV formats to facilitate migration. However, there is no automated migration tool, so moving to another platform requires manual import and mapping of data.

Brex FAQ
Does Brex provide APIs for exporting transaction data for offline analysis or integration with custom tools?
Yes, Brex offers APIs that allow companies to export transaction and expense data. However, the API access is primarily designed for integration with popular accounting software rather than fully custom offline workflows. Users can export CSV files manually for offline use, but real-time offline functionality is limited.
Community insight informed by Reddit discussions
Can I self-host any part of Brex's platform or is it fully cloud-based?
Brex is a fully cloud-based financial platform with no self-hosting options. All data and services are hosted on Brex's infrastructure, and there is no support for on-premise deployment or self-hosting components.
Community insight informed by Hacker News discussions
What are the data ownership and privacy policies for companies using Brex?
Companies retain ownership of their financial data on Brex, but the platform stores and processes this data on its servers. Brex complies with standard financial data security and privacy regulations, but users should review their privacy policy to understand data sharing and retention specifics.
Community insight informed by Forums discussions
Are there any limitations on the Brex API regarding rate limits or data access scopes?
Brex APIs have rate limits to ensure platform stability, typically documented in their developer portal. Access scopes are scoped to financial data relevant to the authenticated company, and some endpoints may require elevated permissions. Detailed limits are not publicly extensive and may require contacting support.
Community insight informed by StackOverflow discussions
How easy is it to migrate financial data out of Brex if we decide to switch platforms?
Brex allows exporting transaction and expense data via CSV and API endpoints, facilitating migration to other platforms. However, there is no dedicated migration tool, so companies need to handle data transformation and import on their own.
