Triggers API

This API enables you to execute Pinkfish workflows that you’ve created and published. With these “trigger” endpoints, you can integrate automated workflows into your applications and systems. You can also trigger one workflow from another workflow - thereby chaining workflows together. There is no API for other services that you might be looking for, such as retrieving monitor logs, billing data, or workflow CRUD operations.

Key Concepts

Workflow: A series of steps that perform a specific task or workflow.
Trigger: A mechanism to initiate a workflow via API call. You must set up a trigger in order to call your workflow by API.
Run: An instance of a workflow being executed.

Execution Models

Our API supports two execution models:

Asynchronous (Fire and Forget)

When you create a trigger for your workflow, you get two options:

API Trigger Endpoint: Use this with the API key in the header (X-API-KEY)
- Format: https://triggers.app.pinkfish.ai/ext/triggers/{triggerId}
- Requires API key in request headers
- Best for server-to-server integrations
Webhook URL: Use this for 3rd party services that can’t set custom headers
- Format: https://triggers.app.pinkfish.ai/ext/webhook/{apiKey}/triggers/{triggerId}
- API key is embedded in the URL path for authentication
- Best for services like Slack, Discord, Linear, Zoom, and other webhook-based integrations

Both options:

Return immediately with a runId in the response header
Run the workflow asynchronously in the background
Don’t return results directly via the API call
Are best for long-running workflows or when immediate response isn’t required

Synchronous (Wait for Result)

When you call a workflow trigger with x-api-wait: true, the API waits for up to 60 seconds for completion
If the workflow completes within this window, the response body contains the results
If the workflow takes longer than 60 seconds, the call returns with a timeout and a runId
Best for quick workflows where you need immediate results

To view the outcome of a workflow run (especially for async calls or timeouts), you have several options:

Check the effects of the workflow (e.g., a created Google Doc or message to Slack). This is entirely up to you to devise.
Load the workflow in the platform UI (you will see results from the last run). Warning: if you have edited your workflow since your last publish, you won’t see results here.
Use the Runs Monitor in the platform to view execution status and results. This is the most reliable and simple method.

Authentication

All API endpoints are authenticated using API keys. Include your API key in the X-API-KEY header of each request:

X-API-KEY: YOUR_API_KEY_HERE

You can generate API keys in two ways:

In the Library section of the platform interface.
While setting up a trigger for a workflow.

Triggering Workflows

Workflows are executed by calling their associated triggers. Each trigger has a unique endpoint and may accept parameters either as query parameters (for GET requests), as form-encoded data, or as a json payload. Set up your trigger(s) in the Workflow editor (requires first publishing a version of your workflow)

Example Requests

Asynchronous Request (Form-encoded)

curl --location 'https://triggers.app.pinkfish.ai/ext/triggers/YOUR_WORKFLOW_ID' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'X-API-KEY: YOUR_API_KEY' \
--header 'x-api-wait: false' \
--data-urlencode 'Hello=World'

Synchronous Request (JSON)

curl --location 'https://triggers.app.pinkfish.ai/ext/triggers/YOUR_WORKFLOW_ID' \
--header 'Content-Type: application/json' \
--header 'X-API-KEY: YOUR_API_KEY' \
--header 'x-api-wait: true' \
--data '{
    "user_request": "what is the capital of France"
}'

Example Responses

Asynchronous Response

The response body will be null. You can find your runId in the header as X-Pf-Run-Id.

Response Body
null

Synchronous Response (Successful)

If the workflow completes within 60 seconds, you’ll receive the results in the response body:

    "automationVersion": 1,
    "automationName": "Hello Triggers",

    },
    "inputs": "",

    "results": [

            "result": {

            },
            "exitCode": 0,
            "duration": 707
        }
    ],
    "started": "2024-11-16T00:01:50Z",
    "startedBy": "588233679836"
}

Synchronous Response (Timeout)

If the workflow doesn’t complete within 60 seconds:

Response Headers
[same as async response]

Response Body
{
    "status": "timeout",
    "message": "Workflow execution exceeded 60 second timeout. Use runId to check results in Run Monitor."
}

Webhook Triggers

Webhook triggers provide an alternative way to execute workflows when working with third-party services that cannot set custom headers (like Slack, Discord, Linear, Zoom, etc.).

Webhook URL Format

https://triggers.app.pinkfish.ai/ext/webhook/{apiKey}/triggers/{triggerId}

Key Differences from API Triggers

Feature	API Trigger	Webhook Trigger
Authentication	API key in `X-API-KEY` header	API key embedded in URL path
URL Format	`/ext/triggers/{triggerId}`	`/ext/webhook/{apiKey}/triggers/{triggerId}`
Use Case	Server-to-server integrations	Third-party services with webhook support
Security	More secure (key in headers)	Less secure (key visible in URL)

Example Webhook Request

POST https://triggers.app.pinkfish.ai/ext/webhook/L2wOL4e7yr6G3Us5LKqHa1BLuhMIW5iR1vAqwFga/triggers/d1a49cl8hlvc714q38e0
Content-Type: application/json

{
    "event": "issue_created",
    "issue_id": "12345",
    "title": "New feature request"
}

Security Considerations

Since the API key is embedded in the webhook URL:

Treat webhook URLs as sensitive credentials
Only share with trusted third-party services
Consider rotating API keys periodically
Monitor webhook usage in the Runs Monitor

Common Webhook Integrations

Slack: Use in Slack workflows or slash commands
Discord: Set up bot commands or server events
Linear: Trigger workflows on issue updates
Zoom: Execute workflows from Zoom apps
GitHub: Run workflows on repository events
Stripe: Process payment events

Getting Started

To begin using the AI Workflow API, you’ll need to:

Create and publish a workflow using our platform.
Set up a trigger for your workflow.
Generate an API key from either the Library section or during trigger setup.
Choose your execution model (sync or async) based on your workflow’s expected runtime and your application’s needs.
Use the provided trigger endpoint to execute your workflow, including your API key and preferred wait setting in the request headers.
