# Use Cases & Integration Ideas

UseStencil webhooks allow you to **automate downstream workflows** the moment a new image is generated. Whether you're using third-party tools or building internal systems, webhooks help eliminate manual steps, trigger following actions, and keep systems in sync.

## Auto-upload to Cloud Storage

**Use Case**: Automatically push the generated image to another cloud storage bucket (e.g. S3, GCS, Azure Blob).

**How**:

* Use an AWS Lambda or a GCP Cloud Function to receive the webhook.
* Fetch the image\_url from the payload and upload it to your destination bucket.
* Use user\_defined to route by environment or team.

## Send Notifications via Slack, Discord or Email

**Use Case:** Notify your team or clients when a new asset is ready.

**How:**

* Use Zapier, Make (Integromat), or n8n to receive the webhook.
* Format a message including image\_url and modifications.
* Post to a Slack or Discord channel, or email a recipient list.

## Sync Image to Product CMS or Storefront

**Use Case:** When an image is created for a product campaign, push it directly to your CMS (e.g. Contentful, Sanity) or eCommerce system (e.g. Shopify, WooCommerce).

**How:**

* Use the `project_id` or a `user_defined.product_id` to identify the target.
* Update or create a record with the image URLs.
* Optionally trigger cache invalidation or a publish workflow.

## Enrich Metadata or Log to Internal Analytics

**Use Case:** Track when and how assets are used, by whom, or for what campaign.

**How:**

* Log the payload into your internal analytics or data warehouse (e.g. via Kafka, Segment, or BigQuery).
* Parse modifications to understand template usage patterns.
* Store `user_defined` keys for later audit or reporting.

## Trigger AI Post-processing or Optimisation

**Use Case:** Automatically feed new images into a compression engine, thumbnail generator, or an AI pipeline (e.g., background removal, social resizer, object detection).

**How:**

* Receive the webhook, and download the image via image\_url.
* Pass it to a processing tool like TinyPNG API, Remove.bg, or your model.
* Store processed images separately or update the same resource.

## Automatically Generate PDFs or Marketing Collateral

**Use Case:** Combine the image into a PDF, sales sheet, or multi-page collateral automatically.

**How:**

* Use the image\_url as an asset source.
* Feed it into a PDF generation tool (e.g. Puppeteer, PDFKit, or CloudConvert).
* Save and distribute the document or attach it to a CRM record.

## Chain Other Internal Workflows

**Use Case:** Kick off internal approval, ticket creation, or downstream service calls.

**How:**

* Trigger a Jira or Trello card via webhook.
* Open a support ticket via Intercom or Zendesk APIs.
* Trigger another system's API with enriched image metadata.

> ####  Tip: Leverage `user_defined` for Routing Logic
>
> Add static or dynamic fields to the webhook config so your receiver knows:
>
> * Which app/team/org triggered the event
> * What action should follow ("action": "send-to-salesforce")
> * What template or purpose it was for ("label": "product-campaign", "env": "staging")
