## Creating a Webhook for Violet in Precoro
Optionally, you can configure a webhook in Precoro that will allow Violet to fetch data on an event-driven basis. This also helps minimize the impact of API limits that Precoro places on the number of requests that it will process.
The webhook will notify Violet when something in Precoro has been created or updated, allowing Violet to fetch that new information in \[near] real-time.
To add a webhook, follow the instructions below:
1. Navigate to [app.precoro.us](https://app.precoro.us/manage/webhook_notification_configurations)
2. Click **New Webhook**
3. In the **Endpoint of your webhook** field, enter `https://`**``**`/api/violet-entity-fetch/webhook?applicationId=b0a5e080-662a-47b5-a1a2-3466a1d02317`, with your Violet URL as **\**. \
\
For example, if your Violet domain is **acme.violetlabs.com**, you should enter `https://acme.violetlabs.com/api/violet-entity-fetch/webhook?applicationId=b0a5e080-662a-47b5-a1a2-3466a1d02317`.
4. Under **Select what events to track with webhook**, select the `Create` and `Update` checkboxes for ***Purchase Order***, ***Purchase Requisition***, and ***Invoice***.
5. Click **Save**.
6. Last, ensure the webhook is switched to `Activated`.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.violetlabs.com/apps/p/precoro.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
