An Optimizely Content Management System (CMS) installation with Optimizely Forms, and the required Marketing Automation connector components. See [Optimizely Connect for Marketing Automation](🔗).
The **Connect for Eloqua MA connector** is installed through the NuGet package [EPiServer.MarketingAutomationIntegration.Eloqua](🔗). See [Add-ons platform compatibility](🔗) for supported Optimizely versions.
To configure your Optimizely website to use Eloqua, you need an Eloqua license that provides you with a username, password, and company name. You also need to configure the connection of form fields to Eloqua, so that data from the specified fields can be sent to Eloqua.
These configurations are described in [Eloqua connector](🔗) in the Optimizely User Guide.
## Encrypt credentials
Credentials are encrypted and saved based on one of the following options:
**MAICryptoKey** (AES encryption with an SHA256-computer hash based on the value of the key)
**machineKey** of the server in _web.config_.
For DXP instances, use **MAICryptoKey**.
If you choose to use **machineKey** configuration, you should specify a **machineKey** in the web.config of your site so that when you deploy it to a different server, the same machine key is used on the new server.
If you neglect to specify a **machineKey** in the _web.config_, the credentials are removed when the site on the new server is accessed for the first time, in which case you need to save credentials again through the configuration screen.
If the credentials are already encrypted using **machineKey** in an existing site, and the **MAICryptoKey** setting is added, then the credentials are deleted and must be re-entered.
Similarly, if the encryption uses **MAICryptoKey** first and then you decide to use **machineKey** encryption (by deleting the **MAICryptoKey** setting), then the credentials are deleted and must be re-entered.
## Submitting Form data to an Eloqua form
You can submit data from Optimizely Form to a form in Eloqua. This provides extra features like analytics, user activity on the site, and data regarding which form created which contact.
### How it works
Existing Optimizely Form functionality and this added functionality each send form data from Optimizely to Eloqua. The difference is that this feature also makes a post to an Eloqua form.
See also the documentation video: [Personalization with Eloqua](🔗)
To get the added functionality, perform the following steps.
Create a form in Eloqua; see [Creating forms](🔗) from the Oracle website.
Select **Change Contact's Email Address** and set it up as follows.
Select **Update Contacts - With Form Data** and set it up as follows:
Create a form with the same set of fields as the Eloqua form created in step# 1. Map these fields to the appropriate fields in the field mapping drop-down.
Add a pre-defined hidden field with the values to the form you created, and map it to **elqFormUrl** in the field mapping drop-down as shown.
The hidden field should look like the following image:
The value of the **elqFormUrl** hidden field should be only the URL displayed in quotes in the following picture; the **“action=”** part should be omitted.
Form integration details are in the Eloqua portal, where you create a form in Eloqua. This is where you get the value for **elqFormUrl**. For reference see, [Capturing submission data from an external form](🔗) on the Oracle website.
Add the following hidden fields to the HTML of your forms page. You can use a custom block that outputs raw HTML/scripts, or add them directly on the template which renders the form. See [Reposting externally hosted forms](🔗) on the Oracle website.
The form is ready. When you submit the Optimizely form, it creates a contact and also records the submission of the Eloqua form.
