Point follower
Sometimes a customer wants to be the point master (that is, to own and calculate their end-user's points in their own system). But they might still want to use Engage's functionality for visualizing and adding points based on non-purchase events like engagements, birthday, reviews or whatever.
In this case, Engage can be configured to be the point follower. Engage and the point master system must then sync points with each other, with the point master being the single source of truth.
Important
Point follower, on a functional level, means that Engage stops generating points from purchases.
Engage receives the current point balances for a contact from the point master system and sets the total in Engage to this value. Not that there will be no information sent about why the balance changed.
This method also doesn't allow member level functionality in Engage.
The point follower solution
The current Engage-as-point-follower solution uses a combination of API endpoints and webhooks.
You can see a general introduction to webhooks here.
There are three parts to the solution:
The point master sends balance-only updates via the Engage API
Engage imports the points log from an external API provided by the point master
Engage exports point adjustments to the point master via a webhook
1) Balance-only points update via the API
The point master needs to regularly send points updates to Engage so that both systems remain in sync. This is done using this Engage API endpoint:
POST /api/v2/point-accounts/balances
The payload has the following form:
[
{
"contactId": "00000000-0000-0000-0000-000000000001",
"amount": 122,
"definitionId": 1,
"timeStamp": "2023-05-16T12:20:03.807Z"
},
{
"contactId": "00000000-0000-0000-0000-000000000002",
"amount": 63,
"definitionId": 1,
"timeStamp": "2023-05-16T12:20:03.807Z"
}
]When the point master calls this endpoint, Engage receives the request and puts it into a queue. A unique transaction ID is also returned. When the job BalanceAccountToAmountJob is run, the queue is processed and the received point balance is then set in Engage for each of the contacts, putting Engage in sync with the point master
If the point master needs to track how the requests are being processed in Engage, it can use the following endpoint along with the transaction ID it received when it posted to /api/v2/point-accounts/balances:
GET /api/v2/point-accounts/balances/status/{id}
The response from this call will be in this form:
{
"messages": [
{
"message": "string",
"timeStamp": "2023-05-17T11:03:16.947Z"
}
],
"id": "string",
"status": "string",
"timeStamp": "2023-05-17T11:03:16.947Z"
}2) Points log via an external API
When Engage is acting as point follower, it does not hold the points log (points history) for a contact. The point master owns all that information. Engage, however, can fetch the points log using an external API supplied by the point master, and then display it on the contact card.
The API call will look something like this:
GET https://someUrl.com/fetchPointHistory?id=contactId
The value "contactId" here is the ID of the contact in question.
Note
This URL is hosted by the point master on their end.
This URL needs to be entered into the Engage back-end. Your Voyado team will do this.
The point master needs to ensure the response from the endpoint has this form:
[
{
"transactionDate": "2023-05-08T12:06:58Z",
"amount": 1900,
"description": "Purchase of tshirt"
},
{
"transactionDate": "2023-05-08T12:02:55Z",
"amount": 1500,
"description": "Purchase of jeans"
}
]Or, if the contact in question has no points yet, the response should be an empty array:
[]
3) Points adjustment via a webhook
If a points adjustment is made in Engage manually in the UI or by an automation, and Engage is acting as point follower, then that adjustment is not made right away. Instead it is sent as a request to the point master system. This is done using a webhook, provided by the point master and configured in Engage.
Once the point master has received the update, the points change will only be visible in Engage when the point master performs its next sync (see step 1 for how that works).
Caution
Points adjustments made in Engage when it is acting as point follower might not have an immediate effect. You might have to wait for the next sync from the point master.
The data sent over the webhook has the following form:
{
"eventType": "loyalty.addPoints",
"id": "70b84f00-d212-47c0-a56d-feaab6294333",
"payload": "FtaW9DkGDs8yZGxkHU5Urh5B3fYpdjJylVwlCMUj1YlqcJ+9VVxO5dIhawwF2mbDJIkP1B9IVTM9+he86ZFBcIzGLr3K9nhH1hXuc0527Pkruan5TGsanjj4Kf2+7ZueY2FG6Vu5+nEuecxsDBgREyHOynieMBKRlBn3b1AVq7vw9D3dMdE6PpDGKFVAqrxrfP8jmmnPCn7orP4qAIxq6X67D8Jya4bs6ixJvZ66HPUwkmg0cEKiAhtgUlZko9XXMMPJUvHssQuIe6zhfx2r/bH9zwfbKPCNuTQ9q74iSc2CoA9akwCgk/f+PqnYspSznEnBvbwBUYlNoq39MOjjAtoMOoZD8+Jb3SGV9UxL8rHroSlOEttp1c7mX61UFIFCdo/OluCc54ycrjIx9Jgmww==",
"tenant": "pointfollower"
}The payload part is encrypted. The encryption key used must be entered into the Engage back-end, and also communicated separately to the point master system so they can perform the decryption with the same key. Once decrypted, the form of the payload will depend on whether the points adjustment was done via an automation, or manually in the Engage UI.
Points adjustment through an automation
In this case, the decrypted payload will look like this:
{
"ContactId": "1dfe06cd-a1be-4423-8ed4-afd900d998aa",
"Amount": 40,
"Description": "Points awarded",
"Source": "Automation",
"PointDefinitionId": 1,
"Reason": "Voyado",
"ProcessId": "d6342090-7410-4c00-aa4b-dbd394dac7e6",
"WorkflowId": "44931e65-e188-46c4-92bd-50e4818fece2",
"WorkflowName": ""
}The attributes ProcessId, WorkflowId and WorkflowName refer to the automation.
Points adjustment made manually in Engage
In this case, the decrypted payload will look like this:
{
"ContactId": "1dfe06cd-a1be-4423-8ed4-afd900d998aa",
"Amount": 40,
"Description": "Give points from Engage",
"Source": "Manual",
"PointDefinitionId": 1,
"UserId": "c23f28cb-d62d-42cf-9d11-b919198409ea",
"UserName": "Jimmy User",
}The UserId and UserName here refer to the user who made the change in Engage.
The point master system can now read the points adjustment and apply it.
Viewing points in Engage
As mentioned, when Engage is point follower, adjustments are not applied directly, but instead sent to the point master using the webhook, and from there back to Engage via the API when the next sync happens.
Caution
It's important that the webhook from the point master is configured in Engage before the customer starts using it, or else points updates from automations and so on will be missed.
In the Engage UI, the user can view the points added and sent out:
The Engage UI acts as an iFrame for showing point transactions after collecting them though the point master's API.
