Integration Guide

15 minutes

Prerequisites

A Pictify account with an API key
n8n installed (cloud or self-hosted)
A template created in Pictify

Store Your API Key as a Credential

In n8n, go to Settings → Credentials → Add Credential. Create a "Header Auth" credential with your Pictify API key.

Code

Name: Pictify API
Header Auth:
  Name: Authorization
  Value: Bearer YOUR_API_KEY

Using credentials keeps your API key secure and reusable across workflows.

Create a New Workflow

Click "New Workflow" in n8n. Add a trigger node—use Manual Trigger for testing or Webhook/Schedule for production.

Add an HTTP Request Node

Add an "HTTP Request" node and connect it to your trigger. This will call the Pictify API.

Configure the HTTP Request

Set up the node to POST to Pictify's render endpoint with your template configuration.

Code

Method: POST
URL: https://api.pictify.io/v1/render

Authentication: Predefined Credential Type
Credential Type: Header Auth
Credential: Pictify API (created in step 1)

Send Headers: ON
Header Parameters:
  Content-Type: application/json

Send Body: ON
Body Content Type: JSON
Specify Body: Using Fields Below

Body Parameters:
  templateId: your-template-id
  format: png
  variables: {
    "title": "{{ $json.title }}",
    "subtitle": "{{ $json.subtitle }}"
  }

Use n8n expressions like {{ $json.fieldName }} to map data from previous nodes.

Test the Workflow

Click "Execute Workflow" to run a test. The HTTP node output will contain the generated image URL.

Code

// Success output from HTTP node:
{
  "success": true,
  "imageUrl": "https://cdn.pictify.io/renders/abc123.png",
  "renderTime": 1.5
}

Process the Response

Add subsequent nodes to use the image URL. Common options: save to disk, upload to S3, update database, or send notification.

Code

// Access the image URL in subsequent nodes:
{{ $json.imageUrl }}

// Example: Download the image with another HTTP node
Method: GET
URL: {{ $json.imageUrl }}
Response Format: File

Batch Processing with Loop

For generating multiple images, use the SplitInBatches node to process items one at a time and avoid rate limits.

Code

// Workflow structure for batch:
Trigger → Get Data → SplitInBatches → HTTP Request (Pictify) → Merge → Save Results

// SplitInBatches settings:
Batch Size: 1
Options: Add pause between batches (1 second)

The SplitInBatches node is essential for processing arrays without overwhelming the API.
