Manually Triggering the Opt-In Prompt

You may choose to disable automatic triggering of the opt-in prompt via the Pushly platform. In this scenario you would choose to trigger the prompt based on your own criteria (eg: after a visitor clicks a specific link, visits a specific page, etc).

Triggering the prompt is as easy as calling the show_prompt event when a visitor performs the desired action.

pushly('show_prompt', { checkEligibility: true })

If you want the prompt to show regardless of current subscription status or frequency capping (i.e., manually displaying a bell or custom prompt) this can be simplified to the following code.

pushly('show_prompt')

Adding Attributes to a Subscriber's Profile

You can add attributes to a subscriber's profile and later perform segmentation based on those attributes. For example, you may want to tag visitors who are interested in a specific type of news (eg: politics, sports) so that you can target them with specific notifications.

pushly('profile', {
  'is_paying_subscriber': true,
  'interests': ['poltics', 'news']
});

If you're storing the value of a property as an array you can use the profile_append and profile_remove methods to add or remove values.

// add 'sports' to the subscriber's interests
pushly('profile_append', {
  'interests': ['sports']
});
​
// remove 'fashion' and 'news' from the subscriber's interests
pushly('profile_remove', {
  'interests': ['fashion', 'news']
});

Setting the Subscriber's External ID

Providing a unique User ID for your subscriber allows you to later interact with that subscriber via the Pushly API.

There are two ways to provide the external ID:

On SDK Init

Preferably you may provide the external ID when the SDK is initialized. This requires adding one additional line of code to the load function. Note the new externalId line in the below script:

<script src="https://cdn.p-n.io/pushly-sdk.min.js?domain_key=DOMAIN_KEY" async></script>
<script>
  var PushlySDK = window.PushlySDK || [];
  function pushly() { PushlySDK.push(arguments) }
  pushly('load', {
    domainKey: 'DOMAIN_KEY',
    externalId: 'REPLACE_WITH_USER_ID'
  });
</script>

Via a separate method call

Alternatively you may provide the external ID any time after the SDK has loaded via the following code:

pushly('external_id', 'h7bwKwuE3');

Once a subscriber's external ID has been set you may work with our team to set up bi-directional automated data syncs. The following use cases are common ways that publishers use the external ID via server-to-server requests:

• Sending notifications to individual subscribers programmatically

• Processing unsubscribe requests

• Adding and removing profile attributes and events to subscribers

Determining if a Visitor is Already Subscribed

If you need to know if a visitor is already subscribed to push notifications the following javascript can be used:

PushlySDK.context.user.isSubscribed();

The result of this call will be a boolean true or false representing the subscription status of the visitor.
