# Add a customer request to an issue

Attaches a customer's request, with its text and an optional source URL, to an issue, so the issue shows which customers asked for it.

Customer Requests must be enabled in the workspace settings; they are
available on every Linear plan. On the API, send `customerNeedCreate` with the
`issueId`, the request `body` and either the Linear `customerId` or one of the
customer's `customerExternalId` values; an `attachmentUrl`, such as a support
conversation or call link, is saved as the request's source. To create the
customer first without making a duplicate, `customerUpsert` matches an
existing customer by domain and merges in your external id.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "linear": { "url": "https://mcp.linear.app/mcp" } } }
```

Call the MCP tool `save_customer_need`.

Server URL: https://mcp.linear.app/mcp

### API (official)

- Base URL: https://api.linear.app
- Endpoint: `POST /graphql`
- Auth: send the header `Authorization: $LINEAR_API_KEY`
- Get a key: https://linear.app/settings/account/security
- Docs: https://linear.app/developers/graphql

Before doing anything else, make one read-only call to confirm access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data.
- Never print API keys.
