If you've built a workflow in the Cloud UI and want to trigger it from your codebase, this page shows how. You can run workflows on demand, poll for results, and set up recurring schedules using the Python SDK, TypeScript SDK, or REST API.

This is for workflows defined in the visual editor. If you're writing your entire automation in code (no workflow editor involved), see [Browser Automation](/developers/browser-automations/overview) instead.

## Run a workflow

Pass values for the workflow's input parameters. The call returns immediately with a `run_id` -- the workflow runs asynchronously in the background.

<CodeGroup>
```python Python
import os
import asyncio
from skyvern import Skyvern

async def main():
    client = Skyvern(api_key=os.getenv("SKYVERN_API_KEY"))

    run = await client.run_workflow(
        workflow_id="wpid_123456789",
        parameters={
            "resume": "https://example.com/resume.pdf",
            "job_url": "https://jobs.lever.co/company/position"
        }
    )

    print(f"Run ID: {run.run_id}")

asyncio.run(main())
```

```typescript TypeScript
import { SkyvernClient } from "@skyvern/client";

async function main() {
  const client = new SkyvernClient({
    apiKey: process.env.SKYVERN_API_KEY,
  });

  const run = await client.runWorkflow({
    body: {
      workflow_id: "wpid_123456789",
      parameters: {
        resume: "https://example.com/resume.pdf",
        job_url: "https://jobs.lever.co/company/position",
      },
    },
  });

  console.log(`Run ID: ${run.run_id}`);
}

main();
```

```bash cURL
curl -X POST "https://api.skyvern.com/v1/run/workflows" \
  -H "x-api-key: $SKYVERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "workflow_id": "wpid_123456789",
    "parameters": {
      "resume": "https://example.com/resume.pdf",
      "job_url": "https://jobs.lever.co/company/position"
    }
  }'
```
</CodeGroup>

**Example response:**

```json
{
  "run_id": "wr_486305187432193510",
  "status": "created"
}
```

### Run parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `workflow_id` | string | Yes | The `workflow_permanent_id` returned when creating the workflow |
| `parameters` | object | No | Values for the workflow's input parameters. Keys must match the `key` field in the workflow's parameter definitions |
| `title` | string | No | Display name for this specific run |
| `proxy_location` | string or object | No | Override the workflow's default proxy location |
| `webhook_url` | string | No | URL to receive a POST request when the workflow completes |
| `browser_session_id` | string | No | Reuse a persistent browser session (prefix `pbs_`) |
| `browser_profile_id` | string | No | Reuse a browser profile with saved cookies and storage (prefix `bp_`) |

---

## Get results

Workflows run asynchronously, so you need to check back for results. You have two options: poll the API, or receive a webhook when the workflow completes.

### Option 1: Polling

Poll `get_run` until the status reaches a terminal state.

<CodeGroup>
```python Python
run_id = run.run_id

while True:
    result = await client.get_run(run_id)

    if result.status in ["completed", "failed", "terminated", "timed_out", "canceled"]:
        break

    await asyncio.sleep(5)

print(f"Status: {result.status}")
print(f"Output: {result.output}")
```

```typescript TypeScript
const runId = run.run_id;

while (true) {
  const result = await client.getRun(runId);

  if (["completed", "failed", "terminated", "timed_out", "canceled"].includes(result.status)) {
    console.log(`Status: ${result.status}`);
    console.log(`Output: ${JSON.stringify(result.output)}`);
    break;
  }

  await new Promise((resolve) => setTimeout(resolve, 5000));
}
```

```bash cURL
#!/bin/bash
RUN_ID="wr_486305187432193510"

while true; do
  RESPONSE=$(curl -s -X GET "https://api.skyvern.com/v1/runs/$RUN_ID" \
    -H "x-api-key: $SKYVERN_API_KEY")

  STATUS=$(echo "$RESPONSE" | jq -r '.status')
  echo "Status: $STATUS"

  if [[ "$STATUS" == "completed" || "$STATUS" == "failed" || "$STATUS" == "terminated" || "$STATUS" == "timed_out" || "$STATUS" == "canceled" ]]; then
    echo "$RESPONSE" | jq '.output'
    break
  fi

  sleep 5
done
```
</CodeGroup>

### Option 2: Webhooks

Pass a `webhook_url` when running the workflow. Skyvern sends a POST request to your URL when the workflow reaches a terminal state.

<CodeGroup>
```python Python
run = await client.run_workflow(
    workflow_id="wpid_123456789",
    parameters={
        "resume": "https://example.com/resume.pdf",
        "job_url": "https://jobs.lever.co/company/position"
    },
    webhook_url="https://your-server.com/webhook"
)
```

```typescript TypeScript
const run = await client.runWorkflow({
  body: {
    workflow_id: "wpid_123456789",
    parameters: {
      resume: "https://example.com/resume.pdf",
      job_url: "https://jobs.lever.co/company/position",
    },
    webhook_url: "https://your-server.com/webhook",
  },
});
```

```bash cURL
curl -X POST "https://api.skyvern.com/v1/run/workflows" \
  -H "x-api-key: $SKYVERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "workflow_id": "wpid_123456789",
    "parameters": {
      "resume": "https://example.com/resume.pdf",
      "job_url": "https://jobs.lever.co/company/position"
    },
    "webhook_url": "https://your-server.com/webhook"
  }'
```
</CodeGroup>

The webhook payload contains the same data as the polling response. See [Webhooks](/developers/going-to-production/webhooks) for authentication and retry options.

## Schedule a workflow

Schedules let you run any workflow automatically on a recurring basis. Define a cron expression and timezone, and Skyvern triggers the workflow at each interval.

### Create a schedule

<CodeGroup>
```python Python
import os
import asyncio
from skyvern import Skyvern

async def main():
    client = Skyvern(api_key=os.getenv("SKYVERN_API_KEY"))

    result = await client.agent.create_workflow_schedule(
        workflow_permanent_id="wpid_123456789",
        cron_expression="0 9 * * 1-5",
        timezone="America/New_York",
        name="Weekday morning report",
        description="Runs the data extraction workflow every weekday at 9 AM ET",
        parameters={
            "url": "https://example.com/dashboard",
            "output_format": "csv"
        }
    )

    print(f"Schedule ID: {result.schedule.workflow_schedule_id}")

asyncio.run(main())
```

```bash cURL
curl -X POST "https://api.skyvern.com/api/v1/workflows/wpid_123456789/schedules" \
  -H "x-api-key: $SKYVERN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "cron_expression": "0 9 * * 1-5",
    "timezone": "America/New_York",
    "name": "Weekday morning report",
    "description": "Runs the data extraction workflow every weekday at 9 AM ET",
    "parameters": {
      "url": "https://example.com/dashboard",
      "output_format": "csv"
    }
  }'
```
</CodeGroup>

**Schedule parameters:**

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `cron_expression` | string | Yes | 5-field cron expression (minimum 5-minute interval) |
| `timezone` | string | Yes | IANA timezone identifier (e.g., `America/New_York`) |
| `name` | string | No | Human-readable name for the schedule |
| `description` | string | No | Description of what this schedule does |
| `parameters` | object | No | Workflow parameters to pass on each run |
| `enabled` | boolean | No | Whether the schedule is active. Defaults to `true` |

### Enable and disable a schedule

<CodeGroup>
```python Python
# Disable
await client.agent.disable_workflow_schedule(
    workflow_permanent_id="wpid_123456789",
    workflow_schedule_id="wfs_abc123"
)

# Re-enable
await client.agent.enable_workflow_schedule(
    workflow_permanent_id="wpid_123456789",
    workflow_schedule_id="wfs_abc123"
)
```

```bash cURL
# Disable
curl -X POST "https://api.skyvern.com/api/v1/workflows/wpid_123456789/schedules/wfs_abc123/disable" \
  -H "x-api-key: $SKYVERN_API_KEY"

# Re-enable
curl -X POST "https://api.skyvern.com/api/v1/workflows/wpid_123456789/schedules/wfs_abc123/enable" \
  -H "x-api-key: $SKYVERN_API_KEY"
```
</CodeGroup>

### Delete a schedule

Permanently remove a schedule. This cannot be undone. Runs that were already triggered by this schedule are not affected.

<CodeGroup>
```python Python
await client.agent.delete_workflow_schedule_route(
    workflow_permanent_id="wpid_123456789",
    workflow_schedule_id="wfs_abc123"
)
```

```bash cURL
curl -X DELETE "https://api.skyvern.com/api/v1/workflows/wpid_123456789/schedules/wfs_abc123" \
  -H "x-api-key: $SKYVERN_API_KEY"
```
</CodeGroup>

## List workflows

Retrieve all workflows in your organization.

<CodeGroup>
```python Python
workflows = await client.get_workflows()

for workflow in workflows:
    print(f"{workflow.workflow_permanent_id}: {workflow.title}")
```

```typescript TypeScript
const workflows = await client.getWorkflows();

for (const workflow of workflows) {
  console.log(`${workflow.workflow_permanent_id}: ${workflow.title}`);
}
```

```bash cURL
curl -X GET "https://api.skyvern.com/v1/workflows" \
  -H "x-api-key: $SKYVERN_API_KEY"
```
