Self Hosting Marketing Preferences

If you want to host and brand your marketing preferences page yourself, then you need to edit the link in the email. We'd recommend you create a standard row containing the link so you can drag and drop it in for each email you build rather than editing the link each time.

What your page will need to do#

  • Retrieve marketing preferences for the customer from the Intilery endpoint
  • Update the marketing preferences for the customer by building a new preferences object and POSTing to our endpoint

Generating the Subscription ID#

The default page is hosted by Intilery (see example here):

We pass a customer specific Subscription ID as a parameter on the querystring (s). For custom hosting, this parameter can be named as desired. The merge tag for a customer's subscription id is:

{(customer._subscriptionId)!""}

So the link above is generated using:

https://marketingprefs.intilery.com/content?s={(customer._subscriptionId)!""}

For self-hosting replace with the URL with your own hosted page.

The URL s parameter name can be changed to suit, but the merge tag must remain the same as this property of the customer cannot be renamed.

When you have replaced the link with your-domain Intilery will embed the link in the email with appropriate UTM tracking parameters, e.g.

https://your-domain.com/marketing-preferences/<subscriptionId>?utm_campaign=MyCampaign&utm_medium=email&utm_source=Intilery

Reading the Subscription ID#

e.g. If the link to your marketing preferences page is:

https://your-domain.com/marketing-preferences/{(customer._subscriptionId)!""}

you can read the subscriptionId with some JavaScript:

window.location.href.split('/')[window.location.href.split('/').length-1]

or if the link to you marketing preferences page is:

https://your-domain.com/marketing-preferences?s={(customer._subscriptionId)!""}

you can read the subscriptionId with this JavaScript:

new URLSearchParams(window.location.search).get('s')

Reading the Asset ID / UTM Campaign#

Retrieve the asset ID for the campaign by reading it from the utm_campaign search parameter:

new URLSearchParams(window.location.search).get('utm_campaign')

Retrieving marketing preferences for the customer#

A single endpoint returns the customers marketing preferences with the list of known channels and subscription categories. Note that channels are "opt-in" and categories are "opt-out". If a new subscription category is added, the default status of that category for the customer will be subscribed.

HTTP endpoint#

GET https://events.intilery.com/cdp/marketing-preferences/<subscriptionId>

For example...

GET https://events.intilery.com/cdp/marketing-preferences/276db9bf-ac46-4dc3-bb7d-e94a7eb1de51

Example response#

{    "writeKey": "ZXhhbXBsZTpleGFtcGxlOkVYQU1QTEU=",    "customerId": "276db9bf-ac46-4dc3-bb7d-e94a7eb1de51",    "channels": [{        "channel": "email",        "name": "Email",        "subscribed": true    }, {        "channel": "sms",        "name": "SMS",        "subscribed": false    }],    "categories": [{        "category": "marketing tricks",        "name": "marketing_tricks",        "subscribed": true    }, {        "category": "new product alerts",        "name": "new_product_alerts",        "subscribed": true    }],    "unsubscribeAll": false}

Update the marketing preferences for the customer#

HTTP endpoint#

The same endpoint used to retrieve the customer marketing preferences is also used to update. Only the method is different.

POST https://events.intilery.com/cdp/marketing-preferences/<subscription id>?assetId=<campaign name>

Tracking Unsubscribes by Campaign#

The parameter assetId is optional, but recommended. Pass this back to Intilery to ensure that unsubscribes are attributed to the right campaign.

Example code#

The example POST below updates the example customers marketing preferences as follows:-

  • Unsubscribe from the new_product_alerts subscription category
  • Subscribe to the SMS channel Note that the category/channel fields match up to those in the retrieved preferences. We recommend calling this endpoint from your servers to avoid any browser related CORS or blocking issues.
const data = {    "categories": [{        "category": "marketing_tricks",        "subscribed": true    }, {        "category": "new_product_alerts",        "subscribed": false    }],    "channels": [{        "channel": "email",        "subscribed": true    }, {        "channel": "sms",        "subscribed": true    }],    "unsubscribeAll": false,    "unsubscribeReason": ""};$.ajax({    type: 'POST',    url: `https://events.intilery.com/cdp/marketing-preferences/276db9bf-ac46-4dc3-bb7d-e94a7eb1de51?assetId=MyCampaign`,    crossDomain: true,    contentType: 'application/json; charset=utf-8',    data: JSON.stringify(data),    success: function () {        alert("marketing preferences updated");    }});

Example response#

The endpoint will return a 200 response to indicate success.

Unsubscribing from all communications#

Send the following data to the endpoint

{    "categories": [],    "channels": [],    "unsubscribeAll": true,    "unsubscribeReason": "" // can be set to a string value to be recorded against the customer for your own records}
