Preferences

Pre-Requisites

Integration of JavaScript SDK
Configure preference categories on SuprSend dashboard

Understanding preference structure

This is how a typical preference page will look like:

Preference Page contains 2 sections:

Category-level preference settings (Sections)
Overall Channel-level preference

Preferences data structure

interface PreferenceData {
  sections: Section[] | null;
  channel_preferences: ChannelPreference[] | null;
}

interface ChannelPreference {
  channel: string;
  is_restricted: boolean;
}

interface Section {
  name?: string | null;
  description?: string | null;
  subcategories?: Category[] | null;
}

interface Category {
  name: string;
  category: string;
  description?: string | null;
  preference: PreferenceOptions;
  is_editable: boolean;
  channels?: CategoryChannel[] | null;
}

interface CategoryChannel {
  channel: string;
  preference: PreferenceOptions;
  is_editable: boolean;
}

enum PreferenceOptions {
  OPT_IN = "opt_in",
  OPT_OUT = "opt_out",
}

enum ChannelLevelPreferenceOptions {
  ALL = "all",
  REQUIRED = "required",
}

{
  "sections": [
    {
      "name": null,
      "subcategories": [
        {
          "name": "Payment and History",
          "category": "payment-and-history",
          "description": "Send updates related to my payment history.",
          "preference": "opt_in",
          "is_editable": false,
          "channels": [

              "preference": "opt_in",
              "is_editable": true
            },
            {
              "channel": "email",
              "preference": "opt_in",
              "is_editable": false
            }
          ]
        }
      ]

    }
  ]
}

1.1 Sections

This contains the name, description, and subcategories. We have to loop through the sections list and for every section item if there is a name and description present, then show the heading, and if a subcategories list is present, loop through that subcategories list and show all subcategories under that section heading. Subcategories can exist without sections as the section is an optional field. In that case, the section’s name will not be available. For sections where the name is not present, you can directly show its subcategories list without showing Heading for the section in UI.

interface Section {
  name?: string | null;
  description?: string | null;
  subcategories?: Category[] | null;
}

Property	Description
name	name of the section
description	description of the section
subcategories	data of all sub-categories to be shown inside the section

1.2 Categories (sections -> sub-categories)

This is the place where the user sets his category-level preferences. While looping through the subcategories list for every subcategory item, show the name and description in UI.

interface Category {
  name: string;
  category: string;
  description?: string | null;
  preference: PreferenceOptions;
  is_editable: boolean;
  channels?: CategoryChannel[] | null;
}

Property	Description
category	This key is the id of the category which is used while updating the preference.
name	name of the category to be shown on the UI
description	description of the category to be shown on the UI
preference	This key indicates if the category’s preference switch is on or off. Get OPT_IN when the switch is on and OPT_OUT when the switch is off
is_editable	Indicates if the preference switch button is disabled or not. If its value is false then the preference setting for that category can’t be edited
channels	data of all category channels to be shown below the sub-category. Loop through it to show checkboxes under every subcategory item.

1.3 Category channels (sections -> sub-categories -> channels)

This contains a list of channels, channel preference status and whether it’s editable or not. While looping through the subcategory list for every subcategory item we have to loop through its channels list and for every channel to show channel level checkbox.

interface CategoryChannel {
  channel: string;
  preference: PreferenceOptions;
  is_editable: boolean;
}

Property	Description
channel	name of the channel to be shown on UI. The same key will be used as id of the channel while updating the preference.
preference	This key indicates if the channel’s preference switch is on or off. Get OPT_IN when the switch is on and OPT_OUT when the switch is off
is_editable	Indicates if the preference checkbox is disabled or not. If its value is false then the preference setting for that channel can’t be edited

2. Overall channel preferences

It’s a list of all channel-level preferences. We have to loop through the list and for each item, show the UI as given in the below image.

interface ChannelPreference {
  channel: string;
  is_restricted: boolean;
}

Property	Description
channel	name of the channel to be shown on UI. The same key will be used as id of the channel while updating the preference.
is_restricted	This key indicates the restriction level of channel. If restricted, notification will only be sent in the category where this channel is added as mandatory in preference category settings. True means Required radio button is selected. False means All radio button is selected.

Integration

Get preferences data

Use this method to get preferences data and create the preferences UI by following the above sections. This method should be called first before any update preference methods.

const preferencesResp = await suprSendClient.user.preferences.getPreferences(args?: {tenantId?: string, tags?: string | Dictionary, locale?: string});

Argument (optional)	Description
`tenantId`	Tenant identifier for loading per-tenant preferences. Defaults to the active tenant set in identify or changeTenant. Passing it explicitly overrides the active tenant for that call.
`tags`	Filter categories by tags. Used to filter preference categories based on user’s roles, department or teams. (see Tags)
`locale`	Locale code (for example, `es`, `fr`, `de`, `es-AR`) to fetch preference translations in user’s locale. When provided, category names and descriptions will be returned in the specified locale. If a translation is missing for the requested locale, the system automatically falls back in this order: `locale-region` (for example, `es-AR`) → `locale` (for example, `es`) → `en` (English - always available).

If you are passing tenantId in preference methods, make sure it matches scope.tenant_id passed while creating userToken else error will be thrown due to scope mismatching. Returns: Promise<ApiResponse>

Update category preference

Calling this method will opt-in/opt-out user from that category. When the category is editable and the switch is toggled you can call this method.

const updatedPreferencesResp = await suprSendClient.user.preferences.updateCategoryPreference(category: string, preference: PreferenceOptions);

enum PreferenceOptions {
  OPT_IN = "opt_in",
  OPT_OUT = "opt_out"
}

Returns: Promise<ApiResponse>

Update channel preference in category

Calling this method will opt-in/opt-out users from that category-level channel. When the category’s channel checkbox is editable and the user clicks on the checkbox you can call this method.

const updatedPreferencesResp = await suprSendClient.user.preferences.updateChannelPreferenceInCategory(channel: string, preference: PreferenceOptions, category: string);

enum PreferenceOptions {
  OPT_IN = "opt_in",
  OPT_OUT = "opt_out"
}

Returns: Promise<ApiResponse>

Update overall channel preference

This method updated the channel-level preference of the user.

const updatedPreferencesResp = await suprSendClient.user.preferences.updateOverallChannelPreference(channel: string, preference: ChannelLevelPreferenceOptions);

enum ChannelLevelPreferenceOptions {
  ALL = "all",
  REQUIRED = "required"
}

Returns: Promise<ApiResponse>

Event listeners

All preferences update api’s are optimistic updates. Actual API call will happen in background with 1 second debounce. Since its a background task SDK provides event listeners to get updated preference data based on API call status. Listen to this event listeners and update the UI accordingly.

suprSendClient.emitter.on('preferences_updated', (preferenceDataResp: ApiResponse) => void);
suprSendClient.emitter.on('preferences_error', (errorResponse: ApiResponse) => void);

Example Usage: For preferences_error event you could show error toast. For preferences_updated event you could update UI with latest data returned in as param in callback function.

Example

For understanding purpose we have added simple example of preferences implementation in React. You could refer this headless example and design the preferences in your Angular or Vue.js etc. If you want to implement in react please refer @suprsend/react.
