Webhooks

Implementation examples on your webserver.

PHP

    // Example of parsing a application/x-form-urlencoded type webhook
    $data = $_POST;

    // Example of parsing a application/json type webhook
    $data = json_decode(file_get_contents('php://input'), true);

    // Example of parsing a GET request type webhook:
    parse_str($_SERVER['QUERY_STRING'], $data);

    // Squeezely will provide a signature for security
    $signature = $_SERVER['HTTP_X_SQUEEZELY_SIGNATURE'];

Verification of provided signature

X-Squeezely-Signature: NzUxNzBmYzIzMGNkODhmMzJlNDc1ZmY0MDg3ZjgxZDk=

1. Creating the formatted data:
   
   • Form URL encoded callback:
     • Take all received data, in order it was received.
     • JSON encode the data.
   • Callback with raw JSON body:
     
     • Take all data in the message body as a JSON encoded string.
2. Create a binary representation of a HMAC hash by using the data from step 1, the `Webhook Key` using the SHA256 algorithm.
3. Base64 encode the bytes obtained in the previous step.
4. Compare the created hash with the hash obtained from the HTTP request headers. If they are equal the origin is confirmed.

Importing events using Selligent

• Column names should reflect the default event property names as found in the frontend tracking documentation.
• Empty columns will be evaluated and ignored on a per-row basis.
• Events will be dated by using the CREATED_DT column if present. This basically means the order in which events are inserted is significant. Please make sure events are inserted chronologically to ensure profile fields have the most current field values.
• Event rows will be deleted from the article list after importing.
• Custom fields can be added as columns to the table by using the custom field name as shown in the data overview (fields prefixed with custom_*).
• Custom fields will be created automatically when a new column with the custom_* name prefix with a valid data type has been detected for the first time.
• Custom fields of the Text type have a maximum length of 255 characters. When exceeding this value only the first 255 characters will be used.
• Please contact us if a Selligent REST API IP whitelist is used. Calls to the Selligent REST API will originate from one or more of our servers. We can provide you with an up to date list.
