Requirements

  • CRM or Database

Setup

Step 1. Map Your Users

The best practice for detecting social activity and targeting your users is to save your unique User IDs to OneSignal using our setExternalUserId method on each of our SDKs. Another option is to save each OneSignal Player ID in your CRM or database. Please see our CRM Integration docs for more on how to do either option.

Step 2. Detect The Activity or Event

When the user performs the social action you need to capture the event, the User ID that performed the action and the User ID that received the action. Generally this will be saved to a database of events.

OneSignal does provide the option to Add Data Tags to devices, but this is limited and should be used sparingly to collect either "total likes", "total follows", etc. You can also use tags for Message Personalization which will show the current user's name that receives the push. For example, you can send a message "Hi Jon, you have 10 followers." by tagging each user with their "name" and incrementing their followers count.

Step 3. Send The Message

Now that you have the User IDs and actions, you can send a notification with the API by targeting your unique User IDs with the include_external_user_ids parameter or target the OneSignal Player ID with the include_player_ids targeting parameter.

Please see API Examples for more info on using our API calls.

OneSignal also provides the postNotification method which you can use to trigger a notification immediately from within the app or website. Make sure to only target player_ids in this case with the include_player_ids parameter so you do not accidentally expose the OneSignal REST API Key for your app.

Examples

User A gets "Liked" by User B.

When User B performs the "Like", your CRM or Database detects this and you have User A's OneSignal Player ID or your unique User ID.

You can use the API to send a notification to User.

curl --include \
     --request POST \
     --header "Content-Type: application/json; charset=utf-8" \
     --header "Authorization: Basic YOUR_REST_API_KEY" \
     --data-binary "{\"app_id\": \"YOUR_APP_ID\",
\"contents\": {\"en\": \"You got a new Like!\"},
\"include_player_ids\": [\"USER_A_PLAYER_ID\"]}" \
     https://onesignal.com/api/v1/notifications

curl --include \
     --request POST \
     --header "Content-Type: application/json; charset=utf-8" \
     --header "Authorization: Basic YOUR_REST_API_KEY" \
     --data-binary "{\"app_id\": \"YOUR_APP_ID\",
\"contents\": {\"en\": \"You got a new Like!\"},
\"include_external_user_ids\": [\"YOUR_USER_ID\"]}" \
     https://onesignal.com/api/v1/notifications

Comments or Group Involvement

User A has created a post that User B, C and D has commented on.

You would associate User A's external_user_id or player_id to that post as the "author" or "creator".

When User B makes a comment, you can now save User B's ID as a "commenter" to the post and trigger a push to User A. You can save the comment as the message "contents" and have the title as "New Activity" or "New Comment: Post Title".

When User C, D or A also comments or replies, you can then save the new User IDs to the "commenters" array and target all IDs when new updates are made.

Extra add-ons

Personalize the messages

Requires the OneSignal Player ID to tag devices with API
Otherwise, you will need to tag devices with the SDK.

You can then add personalizations to the notification using Message Personalization )

When User A gets the new social Activity, you can tag User A with User B's name.
This is achieved with the Edit Device API PUT call

curl --include \
     --request PUT \
     --header "Content-Type: application/json" \
     --data-binary "{\"app_id\" : \"YOUR_APP_ID\",
\"tags\":{\"liked_by\":\"User B\"}}" \
     https://onesignal.com/api/v1/players/USER_A_PLAYER_ID

Activity Feed

You can track notification data within your app by creating an Activity Feed
