Building Custom Workflows with Vyso API: Tips for Developers

When Your DAM Needs to Do More

Developers working with content-heavy platforms often find themselves repeating the same tasks: pulling assets, transforming them for different channels, publishing them to various endpoints, and keeping everything in sync. These jobs are essential but also repetitive. Manually running them through the web interface is fine for small teams or occasional use, but when you have a constant flow of new assets, the friction becomes obvious.

This is where Vyso’s API can turn a Digital Asset Management system from a storage solution into an automated engine. By connecting directly to the API, developers can create workflows that run in the background, trigger on events, and talk to other parts of the tech stack.

Why Build Custom Workflows Instead of Just Using the UI

The user interface is designed for human interaction. It works well for reviewing, approving, and organising assets. But if you are processing hundreds or thousands of files, or need real-time integration with another system, the API is the better tool.

Through the API, you can hook Vyso directly into your CMS, e-commerce backend, mobile app, or marketing automation tools. You can push approved assets live without manual downloads, keep image variants in sync across platforms, or trigger downstream processes like AI tagging or analytics collection.

Automating Publishing with the API

One of the most common developer tasks is getting assets from the DAM into production quickly. Vyso’s API lets you fetch asset metadata, URLs for specific renditions, and any associated rights information.

For example, if you want to automatically update a hero image on your website whenever a new approved version appears in a specific Vyso folder, you can set up a script that checks for changes and pushes the new URL into your CMS.

import fetch from 'node-fetch';

const API_KEY = process.env.VYSO_API_KEY;

const ASSET_FOLDER_ID = '12345';

async function updateHeroImage() {

const res = await fetch(`https://api.vyso.io/v1/assets?folder=${ASSET_FOLDER_ID}&status=approved`, {

headers: { Authorization: `Bearer ${API_KEY}` }

});

const data = await res.json();

if (data.items && data.items.length > 0) {

const latestAsset = data.items[0];

const heroImageUrl = latestAsset.renditions.find(r => r.type === 'web_large').url;

// Example: push to CMS API

await fetch('https://cms.example.com/api/hero-image', {

method: 'PUT',

headers: { 'Content-Type': 'application/json' },

body: JSON.stringify({ imageUrl: heroImageUrl })

});

console.log(`Updated hero image to ${heroImageUrl}`);

}

updateHeroImage();

This approach removes the need for a content editor to log in, download, and re-upload the file. It also ensures the change happens the moment the asset is approved.

Batch Processing for Large Sets of Assets

Another common scenario is batch processing. Suppose you have 5,000 product images that need to be resized, watermarked, and pushed to multiple marketplaces. Doing this manually would be error-prone and time-consuming.

With Vyso’s API, you can retrieve all assets that match a certain search query, apply transformations automatically, and deliver them to each destination. The API supports parameters for rendition requests, so you can pull images in exactly the size and format required by each channel without creating redundant files in storage.

import requests

API_KEY = 'YOUR_VYSO_API_KEY'

SEARCH_TERM = 'product-2025'

headers = { 'Authorization': f'Bearer {API_KEY}' }

params = { 'search': SEARCH_TERM }

response = requests.get('https://api.vyso.io/v1/assets', headers=headers, params=params)

assets = response.json().get('items', [])

for asset in assets:

rendition_url = f"https://api.vyso.io/v1/assets/{asset['id']}/renditions?width=800&format=webp"

r = requests.get(rendition_url, headers=headers)

# Push to marketplace

requests.post('https://marketplace.example.com/upload', files={'file': r.content})

This lets you transform and deliver content programmatically, freeing your team from repetitive prep work.

Event-Driven Workflows

The most powerful automation comes from working in real time. Vyso supports webhooks so you can trigger actions when specific events happen, such as asset upload, approval, or metadata change.

If a photographer uploads new images to a project folder, your webhook handler could immediately start AI tagging, generate social media crops, and prepare a publish-ready package for the marketing team.

// Example Express.js webhook handler

app.post('/vyso-webhook', (req, res) => {

const event = req.body;

if (event.type === 'asset.approved') {

// Trigger custom automation

processApprovedAsset(event.data.id);

}

res.sendStatus(200);

});

Webhooks make your DAM a live part of your infrastructure rather than a static library you pull from occasionally.

Best Practices for API Integrations

When building workflows, keep in mind a few best practices:

Use API keys securely by storing them in environment variables, not in code repositories.
Rate-limit your requests and use pagination to avoid hitting API limits when working with large datasets.
Cache frequently used data like asset metadata to reduce unnecessary calls.
Fail gracefully so that a single failed request does not break the entire workflow.
Log everything for easier debugging when something goes wrong.

How Vyso Supports Developer Flexibility

Vyso’s API is designed to be developer-friendly, with clear endpoints for assets, renditions, metadata, and permissions. You can combine these features to build anything from small automations to full-scale content delivery pipelines. Because transformations are handled on the fly, you can request exactly what you need at the time you need it, rather than maintaining multiple copies of the same file.

This flexibility means you can adapt workflows as your requirements evolve. Adding a new channel, changing a rendition size, or integrating with a new service becomes a matter of adjusting your API calls, not reworking your entire system.

Turning Your DAM Into an Automation Hub

For developers, a DAM with a robust API is more than a storage tool. It is a programmable content hub that can connect to every part of your stack. Whether you are automating publishing, running large-scale batch processes, or responding to events in real time, Vyso’s API gives you the control to build workflows that match exactly how your team works.

The more you automate, the more time your creative and marketing teams have to focus on producing impactful content rather than wrestling with file logistics. That is the real value of custom API workflows: removing bottlenecks, reducing errors, and making your content move at the speed of your ideas.
