BillFlow AP SDK - Execute AP workflows programmatically

Sim Python SDK

The official Python SDK for Sim, allowing you to execute workflows programmatically from your Python applications.

Installation

pip install simstudio-sdk

Quick Start

import os
from simstudio import SimStudioClient

# Initialize the client
client = SimStudioClient(
    api_key=os.getenv("SIM_API_KEY", "your-api-key-here"),
    base_url="https://sim.ai"  # optional, defaults to https://sim.ai
)

# Execute a workflow
try:
    result = client.execute_workflow("workflow-id")
    print("Workflow executed successfully:", result)
except Exception as error:
    print("Workflow execution failed:", error)

API Reference

SimStudioClient

Constructor

SimStudioClient(api_key: str, base_url: str = "https://sim.ai")

• api_key (str): Your Sim API key
• base_url (str, optional): Base URL for the Sim API (defaults to https://sim.ai)

Methods

execute_workflow(workflow_id, input=None, *, timeout=30.0, stream=None, selected_outputs=None, async_execution=None)

Execute a workflow with optional input data.

# With dict input (spread at root level of request body)
result = client.execute_workflow("workflow-id", {"message": "Hello, world!"})

# With primitive input (wrapped as { input: value })
result = client.execute_workflow("workflow-id", "NVDA")

# With options (keyword-only arguments)
result = client.execute_workflow("workflow-id", {"message": "Hello"}, timeout=60.0)

Parameters:

• workflow_id (str): The ID of the workflow to execute
• input (any, optional): Input data to pass to the workflow. Dicts are spread at the root level, primitives/lists are wrapped in { input: value }. File objects are automatically converted to base64.
• timeout (float, keyword-only): Timeout in seconds (default: 30.0)
• stream (bool, keyword-only): Enable streaming responses
• selected_outputs (list, keyword-only): Block outputs to stream (e.g., ["agent1.content"])
• async_execution (bool, keyword-only): Execute asynchronously and return execution ID

Returns: WorkflowExecutionResult or AsyncExecutionResult

get_workflow_status(workflow_id)

Get the status of a workflow (deployment status, etc.).

status = client.get_workflow_status("workflow-id")
print("Is deployed:", status.is_deployed)

Parameters:

• workflow_id (str): The ID of the workflow

Returns: WorkflowStatus

validate_workflow(workflow_id)

Validate that a workflow is ready for execution.

is_ready = client.validate_workflow("workflow-id")
if is_ready:
    # Workflow is deployed and ready
    pass

Parameters:

• workflow_id (str): The ID of the workflow

Returns: bool

execute_workflow_sync(workflow_id, input=None, *, timeout=30.0, stream=None, selected_outputs=None)

Execute a workflow synchronously (ensures non-async mode).

result = client.execute_workflow_sync("workflow-id", {"data": "some input"}, timeout=60.0)

Parameters:

• workflow_id (str): The ID of the workflow to execute
• input (any, optional): Input data to pass to the workflow
• timeout (float, keyword-only): Timeout in seconds (default: 30.0)

• selected_outputs (list, keyword-only): Block outputs to stream (e.g., ["agent1.content"])

Returns: WorkflowExecutionResult

get_job_status(task_id)

Get the status of an async job.

status = client.get_job_status("task-id-from-async-execution")
print("Job status:", status)

Parameters:

• task_id (str): The task ID returned from async execution

Returns: dict

execute_with_retry(workflow_id, input=None, *, timeout=30.0, stream=None, selected_outputs=None, async_execution=None, max_retries=3, initial_delay=1.0, max_delay=30.0, backoff_multiplier=2.0)

Execute a workflow with automatic retry on rate limit errors.

result = client.execute_with_retry(

Examples

Basic Workflow Execution

import os
from simstudio import SimStudioClient

client = SimStudioClient(api_key=os.getenv("SIM_API_KEY"))

def run_workflow():
    try:
        # Check if workflow is ready
        is_ready = client.validate_workflow("my-workflow-id")
        if not is_ready:
            raise Exception("Workflow is not deployed or ready")

        # Execute the workflow
        result = client.execute_workflow(
            "my-workflow-id",
            {
                "message": "Process this data",
                "user_id": "12345"
            }
        )

        if result.success:
            print("Output:", result.output)
            print("Duration:", result.metadata.get("duration") if result.metadata else None)
        else:
            print("Workflow failed:", result.error)
            
    except Exception as error:
        print("Error:", error)

run_workflow()

Error Handling

from simstudio import SimStudioClient, SimStudioError
import os

client = SimStudioClient(api_key=os.getenv("SIM_API_KEY"))

def execute_with_error_handling():
    try:
        result = client.execute_workflow("workflow-id")
        return result
    except SimStudioError as error:
        if error.code == "UNAUTHORIZED":
            print("Invalid API key")
        elif error.code == "TIMEOUT":
            print("Workflow execution timed out")
        elif error.code == "USAGE_LIMIT_EXCEEDED":
            print("Usage limit exceeded")
        elif error.code == "INVALID_JSON":
            print("Invalid JSON in request body")
        else:
            print(f"Workflow error: {error}")
        raise
    except Exception as error:
        print(f"Unexpected error: {error}")
        raise

Context Manager Usage

from simstudio import SimStudioClient
import os

# Using context manager to automatically close the session
with SimStudioClient(api_key=os.getenv("SIM_API_KEY")) as client:
    result = client.execute_workflow("workflow-id")
    print("Result:", result)
# Session is automatically closed here

Environment Configuration

import os
from simstudio import SimStudioClient

# Using environment variables
client = SimStudioClient(
    api_key=os.getenv("SIM_API_KEY"),
    base_url=os.getenv("SIM_BASE_URL", "https://sim.ai")
)

File Upload

File objects are automatically detected and converted to base64 format. Include them in your input under the field name matching your workflow's API trigger input format:

The SDK converts file objects to this format:

{
  'type': 'file',
  'data': 'data:mime/type;base64,base64data',
  'name': 'filename',
  'mime': 'mime/type'
}

Alternatively, you can manually provide files using the URL format:

{
  'type': 'url',
  'data': 'https://example.com/file.pdf',
  'name': 'file.pdf',
  'mime': 'application/pdf'
}

from simstudio import SimStudioClient
import os

client = SimStudioClient(api_key=os.getenv("SIM_API_KEY"))

# Upload a single file - include it under the field name from your API trigger
with open('document.pdf', 'rb') as f:
    result = client.execute_workflow(
        'workflow-id',
        {
            'documents': [f],  # Must match your workflow's "files" field name
            'instructions': 'Analyze this document'
        }
    )

# Upload multiple files
with open('doc1.pdf', 'rb') as f1, open('doc2.pdf', 'rb') as f2:
    result = client.execute_workflow(
        'workflow-id',
        {
            'attachments': [f1, f2],  # Must match your workflow's "files" field name
            'query': 'Compare these documents'
        }
    )

Batch Workflow Execution

from simstudio import SimStudioClient
import os

client = SimStudioClient(api_key=os.getenv("SIM_API_KEY"))

def execute_workflows_batch(workflow_data_pairs):
    """Execute multiple workflows with different input data."""
    results = []

    for workflow_id, workflow_input in workflow_data_pairs:
        try:
            # Validate workflow before execution
            if not client.validate_workflow(workflow_id):
                print(f"Skipping {workflow_id}: not deployed")
                continue

            result = client.execute_workflow(workflow_id, workflow_input)
            results.append({
                "workflow_id": workflow_id,
                "success": result.success,
                "output": result.output,
                "error": result.error
            })

        except Exception as error:
            results.append({
                "workflow_id": workflow_id,
                "success": False,
                "error": str(error)
            })

    return results

# Example usage
workflows = [
    ("workflow-1", {"type": "analysis", "data": "sample1"}),
    ("workflow-2", {"type": "processing", "data": "sample2"}),
]

results = execute_workflows_batch(workflows)
for result in results:
    print(f"Workflow {result['workflow_id']}: {'Success' if result['success'] else 'Failed'}")

Getting Your API Key

1. Log in to your Sim account
2. Navigate to your workflow
