The short answer
As of July 28, 2026, Google’s official Flow help center documents the web and mobile creative product but does not publish a general API for automating Flow projects, Agent sessions, assets or Scenebuilder.
Google does provide programmatic video-generation documentation for Veo through the Gemini API and Google Cloud services. That is not the same as a “Google Flow API.”
What a Flow API would mean
A true Flow product API would need documented endpoints for product objects such as projects, collections, characters, scenes or generated assets. The current official Flow help navigation describes those through the user interface, not public developer endpoints.
What the Veo API is for
Google’s Gemini API documentation covers programmatic video generation with supported Veo models. A developer can submit supported inputs, poll a generation operation and download a result according to the developer platform’s current rules.
Use it when you need:
Application integration.
Server-side generation.
Repeatable programmatic requests.
API authentication, quotas and billing.
Your own asset and job-management layer.
Flow versus Veo API
| Need | Better starting point |
| Visual project workspace | Google Flow |
| Scenebuilder and project assets | Google Flow |
| Built-in Flow Agent | Google Flow |
| Programmatic generation | Gemini API or supported Google Cloud Veo service |
| Custom application workflow | Developer API plus your own application |
| Automating clicks in Flow | Not a documented public API use case |
What about “Google Flow API keys”?
Search results can mix Flow with Gemini API, Vertex AI, browser extensions and unofficial automation. Before entering a key:
Confirm the documentation is on an official Google developer domain.
Identify which product will bill the request.
Never paste a private API key into an untrusted extension or prompt library.
Confirm that the requested model and region are supported by that API.
What about MCP and browser automation?
Community MCP servers or browser automation can exist without being official Flow APIs. They can be fragile when the interface changes and may create account, security or policy risks. FlowTool will label an integration official only when Google publishes and maintains the documentation.

Frequently asked questions
Can I automate Google Flow with an official API?
Google’s current Flow help center does not document a general public API for Flow projects, assets or Scenebuilder.
Can I generate Veo videos with an API?
Yes. Google publishes Veo video-generation documentation for the Gemini API and supported Google Cloud services.
Is a Google Flow MCP server official?
Not automatically. Treat an MCP server as community software unless Google publishes and maintains the integration.
