# How integrations work

Learn the connect-once, enable-per-form pattern that every integration in the app follows.

Every integration in **Powerful Contact Form Builder** works the same way: you connect the account once for your whole store, then switch the integration on for each form that should use it and say which question feeds which field.

## The two places

| Where                                       | What lives there                                                       | Applies to      |
| ------------------------------------------- | ---------------------------------------------------------------------- | --------------- |
| **Settings** > **Third party integrations** | Your account credentials — an API key, a token, or a Google sign-in.   | The whole store |
| Form editor > **Integration**               | The on/off switch, the list or audience choice, and the field mapping. | One form        |

Connecting an account in **Settings** does not send any data on its own. Nothing leaves your store until you switch the integration on inside a form.

{% hint style="info" %}
A few integrations have no **Settings** row at all, because there is no account to connect: **Zapier**, **Make**, **n8n**, **Slack**, **Google Analytics** and **Facebook Pixel** are configured entirely on the form's own panel.
{% endhint %}

### What each service asks for

| Service                                       | What it needs                                                                                    |
| --------------------------------------------- | ------------------------------------------------------------------------------------------------ |
| **Google reCaptcha**                          | **Version** (v2 or v3), **Site key**, **Secret key**                                             |
| **hCaptcha**                                  | **Site key**, **Secret key**                                                                     |
| **Mailchimp**                                 | **Mailchimp API key**                                                                            |
| **Klaviyo**                                   | **Klaviyo API key**                                                                              |
| **Hubspot**                                   | **Hubspot Private App Access Token**                                                             |
| **Omnisend**, **GetResponse**, **Sendinblue** | That service's **API key**                                                                       |
| **Campaign Monitor**                          | **Client ID** and **API key**                                                                    |
| **ActiveCampaign**                            | **API key** and **API Url**                                                                      |
| **Google Calendar / Google Sheets**           | A Google sign-in — see [Google integration](/integrations/google.md#connect-your-google-account) |

When the form is submitted the data from the submission will be pushed to the connected third paries.<br>

## Next steps

* [Mailchimp](/integrations/mailchimp.md) — a full worked example of the pattern on this page.
* [Connect your Google account](/integrations/google.md#connect-your-google-account) — the one integration that uses a sign-in instead of a key.
