# Provision Customer Connections to Your App

Your [custom connector](https://prismatic.io/docs/custom-connectors.md) for your app likely requires authentication, but it feels strange to ask your customers to authenticate with your app when they're already logged in to your app.

The solution is to create customer connections on behalf of your customers, so they don't have to authenticate with your app separately.

If you'd like to provision customer connections programmatically, first create the connection and take note of its ID (it'll start with `U2N...`). Then, take note of your customer's ID (it'll start with `Q3V...`).

With both IDs in hand, create a customer connection, filling `inputs` with the keys and values required by your custom connector. Here's an example GraphQL mutation:

Create a Customer Connection

```graphql
mutation {
  createCustomerConfigVariable(
    input: {
      scopedConfigVariable: "U2N-YOUR-CONNECTION-ID"
      customer: "Q3V-YOUR-CUSTOMER-ID"
      isTest: false
      inputs: [
        { name: "api_key", type: "value", value: "my-customers-api-key" }
      ]
    }
  ) {
    customerConfigVariable {
      id
    }
    errors {
      field
      messages
    }
  }
}

```
