Adobe hello world

Adobe Hello World

Overview

Three minimal working examples covering Adobe's core API surfaces: Firefly AI image generation, PDF content extraction, and Photoshop background removal.

Prerequisites

• Completed adobe-install-auth setup
• Valid OAuth Server-to-Server credentials
• Node.js 18+ with @adobe/firefly-apis or @adobe/pdfservices-node-sdk installed

Instructions

Example 1: Firefly Text-to-Image Generation

// hello-firefly.ts
import 'dotenv/config';
import { getAdobeAccessToken } from './adobe/auth';

async function generateImage() {
  const token = await getAdobeAccessToken();

  const response = await fetch(
    'https://firefly-api.adobe.io/v3/images/generate',
    {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${token}`,
        'x-api-key': process.env.ADOBE_CLIENT_ID!,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        prompt: 'A futuristic cityscape at sunset with flying cars',
        n: 1,              // number of images
        size: {
          width: 1024,
          height: 1024,
        },
        contentClass: 'art', // "art" or "photo"
      }),
    }
  );

  if (!response.ok) {
    throw new Error(`Firefly API error: ${response.status} ${await response.text()}`);
  }

  const result = await response.json();
  console.log('Generated image URL:', result.outputs[0].image.url);
  return result;
}

generateImage().catch(console.error);

Example 2: PDF Text Extraction

// hello-pdf.ts
import {
  ServicePrincipalCredentials,
  PDFServices,
  MimeType,
  ExtractPDFParams,
  ExtractElementType,
  ExtractPDFJob,
  ExtractPDFResult,
} from '@adobe/pdfservices-node-sdk';
import * as fs from 'fs';

async function extractPDF() {
  const credentials = new ServicePrincipalCredentials({
    clientId: process.env.ADOBE_CLIENT_ID!,
    clientSecret: process.env.ADOBE_CLIENT_SECRET!,
  });

  const pdfServices = new PDFServices({ credentials });

  // Upload the PDF
  const inputStream = fs.createReadStream('./sample.pdf');
  const inputAsset = await pdfServices.upload({
    readStream: inputStream,
    mimeType: MimeType.PDF,
  });

  // Configure extraction (text + tables)
  const params = new ExtractPDFParams({
    elementsToExtract: [ExtractElementType.TEXT, ExtractElementType.TABLES],
  });

  // Run extraction job
  const job = new ExtractPDFJob({ inputAsset, params });
  const pollingURL = await pdfServices.submit({ job });
  const result = await pdfServices.getJobResult({
    pollingURL,
    resultType: ExtractPDFResult,
  });

  // Download result ZIP containing structuredData.json
  const resultAsset = result.result!.resource;
  const streamAsset = await pdfServices.getContent({ asset: resultAsset });
  const outputStream = fs.createWriteStream('./extracted-output.zip');
  streamAsset.readStream.pipe(outputStream);

  console.log('Extraction complete: ./extracted-output.zip');
}

extractPDF().catch(console.error);

Example 3: Photoshop Remove Background

// hello-photoshop.ts
import 'dotenv/config';
import { getAdobeAccessToken } from './adobe/auth';

async function removeBackground() {
  const token = await getAdobeAccessToken();

  // Input/output must be pre-signed URLs (S3, Azure Blob, Dropbox)
  const response = await fetch(
    'https://image.adobe.io/sensei/cutout',
    {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${token}`,
        'x-api-key': process.env.ADOBE_CLIENT_ID!,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        input: {
          href: 'https://your-bucket.s3.amazonaws.com/input-photo.jpg',
          storage: 'external',
        },
        output: {
          href: 'https://your-bucket.s3.amazonaws.com/output-cutout.png',
          storage: 'external',
          type: 'image/png',
        },
      }),
    }
  );

  const result = await response.json();
  console.log('Job status URL:', result._links.self.href);

  // Poll for completion
  let status = result;
  while (status.status !== 'succeeded' && status.status !== 'failed') {
    await new Promise(r => setTimeout(r, 2000));
    const poll = await fetch(status._links.self.href, {
      headers: {
        'Authorization': `Bearer ${token}`,
        'x-api-key': process.env.ADOBE_CLIENT_ID!,
      },
    });
    status = await poll.json();
  }

  console.log('Background removal:', status.status);
}

removeBackground().catch(console.error);

Output

• Generated AI image URL from Firefly API
• Extracted PDF text/tables in structured JSON format
• Background-removed PNG from Photoshop API

Error Handling

Error	Cause	Solution
403 Forbidden	Missing API entitlement	Enable the API in Developer Console project
400 Bad Request on Firefly	Invalid prompt or parameters	Check content policy; prompts cannot request trademarks or people
invalid_content_type on PDF	Wrong MimeType	Ensure input is actually a PDF, not a renamed file
InputValidationError on Photoshop	Invalid storage URL	Use pre-signed URLs with read/write permissions
429 Too Many Requests	Rate limit exceeded	Implement backoff; see adobe-rate-limits
