Run Titan Flow from API

When You Need to Trigger a Flow From Another System

In some implementations, you need to run a Titan Flow without a user interacting with the Titan UI. This typically happens when automation must be triggered by another system rather than a person.

You might be calling a Flow from your own website, a backend service, an integration tool, or a scheduled process. In these scenarios, the Flow needs to be started programmatically in response to an event, a data change, or a timed job. Titan supports this by allowing existing Flows in your account to be invoked externally, while the workflow logic itself remains fully defined and managed in Titan.

This approach lets you run automation as part of a broader system architecture without duplicating or rewriting Flow logic outside the platform.

How Titan Supports External Flow Execution

Titan provides a Flow API that exposes your Flow projects as callable automation units. Through this API, external systems can discover available Flow projects, identify them by project ID, and retrieve the input parameters required to run a Flow.

Once the required inputs are known, an external system can trigger Flow execution by passing runtime values and then receive any output parameters returned when the Flow completes. The same API can also be used to programmatically promote Flow projects between Titan environments.

By separating execution from the user interface, you can reuse the same Flow across multiple systems, automate environment management, and keep all workflow logic centralized in Titan without duplication.

How to Run a Flow Using the API

Do the following:

1. Navigate to the Titan API page.

2. Click the Flow option. The following methods are available:

• Get All Flow Projects: This method will return a list of active Flow projects in your Titan account. The Flow ID and name for each project will be returned.

• Get Flow – Get Details: This method will receive the Flow ID (required) and return all input parameters the Flow can access. It will return the details of a specific Titan Flow project in your account after entering the Flow ID in the Flow ID field.
  • The specific input parameters for the specific Flow are returned as a list.

• Flow – Trigger Flow: This method receives the Flow ID and input parameters and triggers the Flow to execute. If this Flow has output parameters (results), they will be returned in the API response. This method requires the following:
  • Flow ID (required).
  • Mode: Select Test or Production mode (required).
    • Test: the Titan project has been saved.
    • Production: The Titan project has been published.
  • Parameters: When you use the Get Flow – Get Details method, you receive the inbound parameters, and you can send what you need to the Titan Flow.

• Copy Flow Projects between two Titan accounts: This method exports a Titan Flow project from one Titan account to another, for instance, from Sandbox to Production.
  • Add the Titan destination API key (required).
  • Add the destination User ID (required).
  • List of Flow IDs that you want to copy (required).
