A REST API for your own software
Read customers and estimates and create drafts from your own tools with the Bid & Sign REST API, API keys and OAuth apps.

If you run your own software, it can now talk to Bid & Sign. The REST API reads customers and estimates, creates customers and creates draft estimates.
Two ways in
- API keys for your own scripts, each with its own permissions.
- OAuth apps so someone on your team can approve an app without sharing a key. PKCE is required.
There is an OpenAPI description for code generators and a limit of 120 requests per minute.
