How it plays out on a deal
Most single-deal users never touch an API. It matters for serial acquirers, advisers running many rooms and companies that want rooms provisioned from their own systems, such as a deal pipeline tool or a document management system.
Check whether the API is publicly documented, which actions it covers and whether it respects the same permissions and audit logging as the web interface. Some vendors limit API access to enterprise contracts.
What to check in a review or demo
- 1Whether API documentation is public and which actions it supports.
- 2Whether API actions are recorded in the audit trail.
- 3Which plans include API access and whether usage limits apply.
