Add Transaction

See the sample example of how a transaction can be added. Links to more detailed instructions can be found at the end of the article.

How this example works

In this example, we will create a sample transaction to trigger the previously created campaign.

---

Try yourself

• Input the previous saved token and storeCode in the request header

• Add a transaction Endpoint: POST /api/{storeCode}/transaction

  {
      "transaction": {
          "items": [
              {
                  "sku": "12AB",
                  "name": "Restaurant",
                  "quantity": 1,
                  "grossValue": 500,
                  "category": "dine"
              }
          ],
          "header": {
              "documentType": "sell",
              "documentNumber": "12345",
              "purchasePlace": "onsite",
              "purchasedAt": "2024-05-01T00:00:00", // add current time
              "labels": []
          },
          "customerData": {
              "email": "[email protected]"
          }
      }
  }

• This action should trigger CampaignEffectWasApplied webhook

Authorizations

Bearer

AuthorizationstringRequired

Open Loyalty has the JWT authorization. To learn what a JSON Web Token is and how it works, check out Introduction to JSON Web Tokens https://jwt.io/introduction/

Obtain an access token

Send a request with the parameters username and password

Definition

POST /api/admin/login_check Go to definition
POST /api/{storeCode}/member/login_check Go to definition

Example

curl {HOST}/api/admin/login_check
    -H 'Content-Type: application/json;charset=UTF-8'
    -H 'Accept: application/json, text/plain, */*'
    --data-binary '{"username":"admin","password":"password"}'

Example Response

{
    "token":"eyJhbGciOiJSUzI1NiIsInR5cCI6...",
    "refresh_token":"0558f8bb29948c4e54c443f..."
}

Using JSON Web Token

Add authorization header to each request
Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6...
You can now access any API method you want under the /api prefix.

Example

curl {HOST}/api/{storeCode}/analytics/members
    -H 'Accept: application/json'
    -H 'Content-type: application/x-www-form-urlencoded'
    -H 'Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6...'

Refresh JSON Web Token

You can refresh token using refresh_token that was given during login.
There are two endpoints
To refresh admin token POST /api/token/refresh Go to definition
To refresh member token POST /api/{storeCode}/token/refresh Go to definition
