Anything Synthflow AI exposes through its API. Common ai agents workflows on Definable include automate repetitive tasks, sync data with the rest of your stack, trigger on real-world events. Personas can call any of the 79 Synthflow AI tools directly, then chain the result into another integration without you writing code.

How does Synthflow AI authentication work?

Synthflow AI uses API_KEY on Definable. You connect once from the integrations page, scoped to the permissions you choose, and from then on any persona that has the integration enabled can act on your behalf. Tokens are encrypted at rest and rotated automatically.

Is the Synthflow AI integration included in my Definable plan?

Yes — every Definable plan, including Starter, includes access to all 79 Synthflow AI tools. You only need a separate Synthflow AI subscription if Synthflow AI itself charges per seat or per API call.

Is using Synthflow AI through Definable secure?

Every call from a persona to Synthflow AI is logged with the user, persona, prompt, and response. Tokens never leave Definable's secrets vault, scopes are configurable per persona, and you can revoke access at any time from the integration page.

How do I get started with Synthflow AI on Definable?

Sign up for Definable, open the integrations page, find Synthflow AI, and connect via OAuth or API key. You can immediately attach Synthflow AI to any persona and start running workflows. The free Starter plan includes 5,000 credits/month.

What Synthflow AI actions does Definable expose?

Definable exposes all 79 Synthflow AI actions as callable tools — including `Add document to knowledge base source`, `Attach Actions to Agent`, `Attach contact to memory store`, plus 76 more. Each tool gets a typed parameter schema so personas know exactly how to call it.
