Account Engagement -- the product that was Pardot -- logs in through Salesforce. If you have already
connected Salesforce, the consumer key, secret and refresh token are the same ones.

## What you need

Four values from your **Salesforce connected app**, with the `pardot_api` scope on it: the consumer
key, the consumer secret, a refresh token, and whether it is production or a sandbox.

And one more that is only for this: the **business unit id**.

## The business unit id, and why it is asked for

It is the 18-character id of the tenant, from Salesforce Setup, *Account Engagement Setup*, *Business
Unit Setup*.

It is asked for explicitly, and its length is checked on the form, because of how the API fails
without it. Sent with no business unit header, a perfectly good token is refused with:

```
401 {"code":49,"message":"Access Denied"}
```

which reads like a credential problem and is not. Sent with the 15-character id Salesforce shows in
some URLs, it is refused again, this time with a message that does say what is wrong:

```
400 Value in Pardot-Business-Unit-Id header is not valid. Expected the 18 character ID of the tenant.
```

Checking it on the connect screen turns both of those into a sentence you can act on before anything
is saved.

## Connect and route

1. In **Destinations**, connect Account Engagement with the five values.
2. The object is **Prospect** -- the only thing a chat lead becomes here.
3. Create a **route** and map the fields.

## What gets sent

The standard prospect fields -- email, first and last name, company, job title, phone, website,
address, comments, source -- plus **your custom fields**, read from the account and offered by their
API name.

**The email address is required.** Account Engagement identifies a prospect by it; a prospect without
one is not a prospect.

## What it does not do

It creates a prospect. It does not add it to a list, and it does not update one that already exists.
List membership is a second call and a second decision -- which list, and when -- and Account
Engagement reconciles an address it already knows on its own side.
