# Set up input sources

After defining the crew's foundational details, the next section is ‘Create Queue’, where you configure how input items reach the agent crew for processing. Receiving these inputs triggers task execution. You can connect external sources like files, forms, emails, or third-party systems. These inputs are queued and processed in sequence by the agents.

* To set up input sources, click on the ‘+ Add an input source’ button. Clicking this opens a sidebar titled ‘Add Input Source’.

* The ‘Add Input Source’ sidebar lists various input connectors that can trigger the crew. You can scroll or use the search bar to find a specific source. Some available input source options include:
  * **Amazon S3** – Triggers when a new file is uploaded to a bucket.
  * **Discord** – Triggers when a message is posted in a specified channel.
  * **Gmail** – Triggers on receiving a new email.
  * **Google Drive (File or folder)** – Triggers when a new file is uploaded or a folder is created.
  * **Google Sheets** – Triggers when a new row is added.
  * **Google Forms** – Triggers when a form is submitted.
  * **Jira Cloud** – Triggers when a new issue is created.
  * **Notion** – Triggers when an item is added to a database.
  * **Salesforce** – Triggers on record creation or update.
  * **ServiceNow** – Triggers on new record creation.
  * **Zendesk** – Triggers when a new ticket is created.
  * **Zoho CRM / Invoice** – Triggers when new data is added.
  * **Webhook (Send data to ZBrain)** – Use this when your external system sends data to ZBrain.
  * **Webhook (Pull data from your system)** – Triggers when a new item is added.

Each input type has its own configuration flow. Clicking on any source will guide you through its specific setup, including creating a connection and setting trigger parameters.

Once added, the input source appears in the queue setup area. You can add more than one input source if needed.

* After adding the input items, click ‘Next’ to proceed to the orchestration setup.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zbrain.ai/zbrain-documentation/zbrain-builder/zbrain-ai-agents/agent-crew/set-up-input-sources.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
