Retrieving transaction details

Discovering the status of an authorized or completed transaction

For authorized or captured transactions, you can retrieve all details of the transaction by sending a GET request to the Bango Payment API, specifying the transaction ID.

The API response is a structure that includes the Bango ID of the purchaser, the payment method used, and the item purchased, as well as custom transaction data specified by the store.

Successful retrieval

The Bango Platform successfully returns the transaction data:

Failed retrieval

The Bango Platform fails to return transaction data:

Skeleton code

function get_transaction (transaction_id) {
    // *Always* use this endpoint prefix for the Bango Payment API.
    const base_url = "";

    // Result value
    let transaction = null;

    try {
        // Send GET with path param to the Bango Payment API and parse the JSON response.
        let response = rest_client_call({
            method: "GET",
            url: base_url + "transaction/" + transaction_id,
            headers: {
                "Authorization": get_authorization_header(),

        // The responseCode tells us the result.
        switch (response.responseCode) {
            // Success
            case "OK":
                transaction = response.transaction;

            // Merchant problems
            // These indicate issues in your code, not the Bango Platform.
            case "BAD_REQUEST":   // Invalid request
            case "UNAUTHORIZED":  // Check your credentials
            case "NOT_FOUND":  // Invalid transaction ID
                throw "Merchant implementation error";

            // Bango Platform issues
            // These likely indicate transient problems.
            // In production code, you might want to try the request again
            // after a delay, ultimately falling back to an error state.
            case "INTERNAL_ERROR":
            case "SERVICE_UNAVAILABLE":
                throw "Bango Platform unavailable"

            // This might indicate Bango has added a new response code.
            // Check the documentation again.
                throw "Unrecognized response code";

    } catch (exception) {
        // Production code might want to notify the merchant in some way,
        // and/or log full details of the exception for later analysis,
        // and degrade gracefully for the user.
        output("An error occurred!");

    // transaction details if found, null if not found
    return transaction;
Which request parameters should I set?

The only parameter is the transaction ID, passed in the path of the request URL.

What are all the possible API response structures?

All responses contain a responseCode string that indicates the result of the request. Use responseCode to determine how to react.

On success, responseCode is OK and the response includes a transaction object. Here's an example response:

    "responseCode": "OK",
    "responseMessage": "Success." ,
    "transaction": {
        "transactionId": "123456789",
        "bangoUserId": "123456789",
        "externalTransactionId": "my-unique-tx-id-12345678",
        "paymentMethod": {
            "type": "OPERATORBILLING",
            "key": "SOME_NETWORK_NAME",
            "description": "Direct operator billing",
            "parameters": {}
        "paymentItems": [
                "itemName": "My item name",
                "itemDescription": "My item description",
                "itemCategory": "1",
                "externalPaymentItemId": "my-unique-payment-id",
                "submerchantReferenceKey": "my-submerchant-ref",
                "price": {
                    "grossAmount": "0.99",
                    "currencyIso3": "USD",
                    "financialBreakdown": {
                        "taxAmount": "0.00"
        "extensionData": {}
