What are SuperAI Flows?

SuperAI Flows automate multi-step document processing pipelines. A typical flow:

Classifies documents (invoice, receipt, contract)
Extracts structured data based on document type
Validates extracted values
Delivers results via webhook or API

Flow definition example

Flows are defined in declarative YAML that’s both human-readable and type-safe. Here’s a complete document processing workflow:

tasks: - name: classify_document task_executor_name: document_classifier parameters: document_url: "{{input.document_url}}" document_types: - invoice - bank_statement - contract

name: extract_data task_executor_name: text_to_structured parameters: document_url: "{{classify_document.splits[0].document_url}}" fields: - id: invoice_number data_type: string - id: total_amount data_type: float instructions: "identify the total amount"
name: validate_results task_executor_name: collection_validation parameters: input_collection: "{{extract_data.total_amount}}" validators: - name: Not Empty Validation

Key features:

Task chaining — extract_data references output from classify_document using {{classify_document.splits[0].document_url}}
Type safety — Each field specifies a data_type (string, float, etc.)
Built-in executors — Use pre-built task executors like document_classifier and text_to_structured
Validation — Chain validation tasks to ensure data quality

The platform automatically resolves dependencies, handles retries, and manages data flow between tasks.

Prerequisites

A SuperAI account ( sign up free)
Your login email and password
curl and jq installed (for testing examples)

Authentication

SuperAI uses JWT-based authentication. All API requests require a valid access token.

Get the anonymous key

This is a public endpoint — no auth required.

curl https://flows.super.ai/api/auth/anon-key

{ "anon_key": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..." }

Exchange credentials for JWT tokens

curl -X POST 'https://core.flows.super.ai/auth/v1/token?grant_type=password'
-H 'Content-Type: application/json'
-H 'apikey: YOUR_ANON_KEY'
-d '{"email": "your-email@example.com", "password": "your-password"}'

{ "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...", "refresh_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...", "expires_in": 3600, "token_type": "bearer" }

Use the access token in every request

curl https://flows.super.ai/api/flows
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

Token management

Token type	Lifetime	When to use
Access token	1 hour	Include in every API request
Refresh token	30 days	Get new access tokens when expired

Tokens grant full account access — treat them like passwords. Store them in environment variables or secret managers, never in code, and always use HTTPS.

When your access token expires, use the refresh token to get a new one without re-authenticating:

curl -X POST 'https://core.flows.super.ai/auth/v1/token?grant_type=refresh_token'
-H 'Content-Type: application/json'
-H 'apikey: YOUR_ANON_KEY'
-d '{"refresh_token": "YOUR_REFRESH_TOKEN"}'

Run your first flow

Start a flow by creating a flow execution with your input data.

curl -X POST https://flows.super.ai/api/flow-executions
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"
-H "Content-Type: application/json"
-d '{ "flow_id": "YOUR_FLOW_ID", "input": { "filename": "invoice-example.pdf", "mime_type": "application/pdf", "document_url": "https://cdn.super.ai/invoice-example.pdf" } }'

{ "id": "df77dc65-909b-430e-bff1-9e9ecf315a80", "flow_id": "550e8400-e29b-41d4-a716-446655440000", "flow_version": 1, "status": "running", "input": { "filename": "invoice-example.pdf", "mime_type": "application/pdf", "document_url": "https://cdn.super.ai/invoice-example.pdf" }, "organization_id": "660e8400-e29b-41d4-a716-446655440001", "created_at": "2024-01-15T10:30:00Z", "updated_at": "2024-01-15T10:30:00Z" }

Key fields:

id — The flow execution ID (use this to check status and retrieve results)
status — Current execution state (running, completed, failed)
flow_version — Version of the flow used (remains constant even if the flow is updated)

The input object structure depends on your flow’s configuration. For file-based flows, provide filename, mime_type, and document_url. Other flows may have different input schemas — check the flow’s input_schema.

Check execution status

curl "https://flows.super.ai/api/flow-executions/df77dc65-909b-430e-bff1-9e9ecf315a80"
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

{ "id": "df77dc65-909b-430e-bff1-9e9ecf315a80", "flow_id": "550e8400-e29b-41d4-a716-446655440000", "status": "completed", "created_at": "2024-01-15T10:30:00Z", "updated_at": "2024-01-15T10:32:45Z" }

Retrieve results

Get task execution results for your flow:

curl "https://flows.super.ai/api/task-executions?flow_execution_id=df77dc65-909b-430e-bff1-9e9ecf315a80"
-H "Authorization: Bearer YOUR_ACCESS_TOKEN"

{ "task_executions": [
{
"id": "e47f2923-1205-4bf2-bee2-2974ddb64aad",
"task_name": "extract_invoice_data",
"status": "completed",
"output": {
"invoice_number": "INV-0052465571",
"total_amount": 2435.00,
"currency": "USD",
"vendor": "Acme Corp",
"date": "2024-01-15"
},
"created_at": "2024-01-15T10:30:05Z",
"updated_at": "2024-01-15T10:32:40Z"
}
] }

Common query parameters:

flow_execution_id — Filter by flow execution (required for most queries)
task_name — Filter by specific task name
task_execution_idx — Filter by execution attempt (0 = first attempt, 1 = first retry)

Webhooks (recommended)

Instead of polling for results, configure webhooks to receive real-time notifications when flows complete. The Webhook Notification task sends POST requests to your specified URL. Add a Webhook Notification task to your flow with these parameters:

Url (required) — Your webhook endpoint URL
Authorization Header Value (optional) — Auth token or API key for securing your webhook
Payload (required) — The data to send (can reference task outputs using {{task_name.field}} syntax)

Example payload:

{ "event_type": "flow_execution.completed", "flow_id": "550e8400-e29b-41d4-a716-446655440000", "flow_execution_id": "df77dc65-909b-430e-bff1-9e9ecf315a80", "status": "completed", "timestamp": "2024-01-15T10:32:45Z", "data": { "task_outputs": { "extract_invoice_data": { "invoice_number": "INV-0052465571", "total_amount": 2435.00 } } } }

Your webhook endpoint should validate the authorization header (if provided via the x-webhook-token header), process the payload, and return a 2xx status code to acknowledge receipt.

Troubleshooting

Authentication failed / Invalid credentials

Verify your credentials work in the web UI first at flows.super.ai.
Check for special characters in your password; wrap it in single quotes to preserve them: export PASSWORD='your-password'.
Verify the anonymous key is valid — it should be a long JWT string.

Flow not found (404)

Verify the flow was created successfully (check the flow creation response).
List all flows you have access to: curl https://flows.super.ai/api/flows -H "Authorization: Bearer $TOKEN".
Confirm you’re using the correct UUID and are logged into the correct organization — flows are organization-specific.

Unauthorized (401) mid-session

Your token expired after 1 hour. Use the refresh token to obtain a new access token (see Authentication).

Bad Request (400) when creating an execution

Validate your JSON is well-formed (pipe it through jq).
For custom flows, check the required input schema: curl "https://flows.super.ai/api/flows/$FLOW_ID" -H "Authorization: Bearer $TOKEN" | jq .input_schema.

Execution stuck in 'running'

Some flows take minutes for complex documents. Use webhooks instead of polling, and inspect task executions to see which task is blocking: curl "https://flows.super.ai/api/task-executions?flow_execution_id=$EXEC_ID" -H "Authorization: Bearer $TOKEN" | jq '.task_executions[] | {task_name, status}'.

Rate limiting (429)

The API implements fair-use rate limiting. If you receive 429 (Too Many Requests), wait before retrying and implement exponential backoff.

Still stuck? Check status.super.ai, then contact support@super.ai with your flow execution ID and the request_id from any error responses.

Error handling

The API uses standard HTTP status codes:

Code	Meaning	Example
200	Success	Request completed successfully
201	Created	Flow execution created
400	Bad Request	Invalid input data or missing fields
401	Unauthorized	Missing or invalid access token
403	Forbidden	Insufficient permissions
404	Not Found	Flow or execution ID doesn’t exist
422	Validation Error	Request body failed validation
500	Server Error	Internal error

Errors follow a consistent format. See the full Error Codes reference.

{ "error": { "code": "not_found", "message": "Flow not found" }, "request_id": "01K8KACP7D2XFGHJ9KLM4NPQR8" }
