API Nodes

To begin building your API, you will need to utilize at least one of the following nodes: Flow API Input, Flow API Output, or Webhook (which will be covered in a later section). This node will define the structure of the API of your AI workflow.

API Input Node​

The API Input Node is used to define the inputs for your API. Each API Input Node corresponds to a field in the request body sent to initiate your flow. The field api_input_name sets the name of the input field in the request body.

Example​

Consider the following configuration:

API Input Node Example

You would send a request body structured as follows:

{
  "my_prompt": "Lorem Ipsum",
  "my_context": "Lorem Ipsum"
}

Each API Input Node can have a default value. If a default value is set, the parameter becomes optional in the request body.

The API Input Node adapts to the type of field it is connected with.

API Output Node​

The API Output Node is straightforward to configure. You only need to set the api_output_name, which will be the name of the field in the final response.

Example​

Consider the following configuration:

API Output Node Example

The final response will be structured as follows:

{
  "my_output": "Lorem Ipsum dolor sit amet, consectetur"
}

Handling Outputs​

You can set as many API Output or API Input nodes as needed. The API Output Node has an output handle and functions like a transition node in a flow. This means it will pass the output to the next node, allowing you to include intermediate results from your flow in the final response if desired.
