# Anvil

> Integrate your application with the Anvil API

## 🚀 Quickstart

Connect to Anvil with Nango and see data flow in 2 minutes.

<Steps>
  <Step title="Create the integration">
    In Nango ([free signup](https://app.nango.dev)), go to [Integrations](https://app.nango.dev/dev/integrations) -> *Configure New Integration* -> *Anvil*.
  </Step>

  <Step title="Authorize Anvil">
    Go to [Connections](https://app.nango.dev/dev/connections) -> *Add Test Connection* -> *Authorize*, then enter your Anvil API key. Later, you'll let your users do the same directly from your app.
  </Step>

  <Step title="Call the Anvil API">
    Let's generate a PDF from Markdown as your first request. Replace the placeholders below with your [secret key](https://app.nango.dev/dev/environment-settings), [integration ID](https://app.nango.dev/dev/integrations), and [connection ID](https://app.nango.dev/dev/connections):

    <Tabs>
      <Tab title="cURL">
        ```bash theme={null}
        curl -X POST "https://api.nango.dev/proxy/api/v1/generate-pdf" \
          -H "Authorization: Bearer <NANGO-SECRET-KEY>" \
          -H "Provider-Config-Key: <INTEGRATION-ID>" \
          -H "Connection-Id: <CONNECTION-ID>" \
          -H "Content-Type: application/json" \
          -d '{
            "title": "Example Invoice",
            "type": "markdown",
            "data": [
              { "label": "Name", "content": "Sally Smith" },
              { "content": "Lorem **ipsum** dolor sit _amet_...", "fontSize": 12, "textColor": "#616161" }
            ],
            "fontSize": 16,
            "textColor": "#171717"
          }' \
          --output invoice.pdf
        ```

        The response is binary PDF bytes — use `--output` to save it as a file.
      </Tab>

      <Tab title="Node">
        Install Nango's backend SDK with `npm i @nangohq/node`. Then run:

        ```typescript theme={null}
        import fs from 'fs';
        import { Nango } from '@nangohq/node';

        const nango = new Nango({ secretKey: '<NANGO-SECRET-KEY>' });

        const res = await nango.post({
            endpoint: '/api/v1/generate-pdf',
            providerConfigKey: '<INTEGRATION-ID>',
            connectionId: '<CONNECTION-ID>',
