Payments

Use ClubCollect as your payment provider

Start Payment

GET https://app.clubcollect.com/api/v2/payments/:payment:method

This endpoint allows to start a new payment and redirects the user to the payment page.To start the payment session, the partner needs to generate the payment URL with the required parameters and add a signature to avoid tampering with data. Payments will always be linked to an invoice in ClubCollect. The invoice will be created ad hoc from the parameters received in the request, unless the partner provides the invoice_id of an existing invoice to be paid. When the invoice_id is given, the payment will be generated for the total amount due for the invoice. An invoice can have many associated payments and each call to the payments endpoint will result in a new payment. The invoices that are generated ad hoc are grouped in batches, per month.These batches can be found on :https://app.clubcollect.com/treasurer/import_batches,named iDEAL (<year>-<month>) by default, e.g. iDEAL (2019-08).

Signature

To ensure authenticity and data integrity of incoming payment requests ClubCollect requires these requests to be signed. This signature is based on a Hash-based Message Authentication Code (HMAC) calculated using a request's key-value pairs and a secret key, which is known only to the partner and ClubCollect.

Before sending a payment request to ClubCollect, the partner has to calculate the signature and add it as a request parameter. When a request comes in, ClubCollect calculates the same signature based on the received key-value pairs and the secret key. By verifying that both signatures are equal, ClubCollect ensures that the request is not tampered.

Similarly, the partner can validate responses from ClubCollect by calculating the corresponding signature and comparing it with the signature in the response.

Let's explain now how to calculate the signature step by step using the key-value pairs in the table below as example.

  1. Concatenate every key-value pair on the list obtained in the previous step to get the signing string

signing_string = params.keys.sort.flat_map { |k| [k, params[k]] }.join

  1. Calculate SHA256 digest of the signing string

digested_content = Digest::SHA256.digest(signing_string)
\tD!()\xAFL\xED\x069\xC0\xEC\x11/\xB3\x93\xFAM\xC0\xA9\xE7\x03\x03\e\xDC\xDFF\x9FZ\x15\xD6\xD1
  1. Calculate HMAC SHA-256 signature of digested signing string using the API key.

hmac_binary = OpenSSL::HMAC.digest(OpenSSL::Digest.new('sha256'), api_key, digested_content)
  1. Encode the result from binary to hexadecimal

signature = hmac_binary.unpack1('H*')
  1. The signature calculated for the example key-value pairs and API key is:

754966cc8946c8125b365fcb5cf0e27edd98fe7516de7ea17f1b5254bcf7a00e
  1. After the signature is generated, it has to be appended to the url query string as

&signature=754966cc8946c8125b365fcb5cf0e27edd98fe7516de7ea17f1b5254bcf7a00e`

Payment response

Once the users finish the payment process, they are redirected to a result page of your choice, included in the payment request as redirect_url.

ClubCollect will append parameters to this URL. payment_result will inform the partner about the payment status. If the status is already determined (either authorised or refused or cancelled), this information can be used to display a payment successful or payment failed or payment cancelled page.

In a case when the current status is pending, the outcome of the payment will be communicated with payment notifications. Payments with status cancelled may be authorized later by the payment provider.

The partner is encouraged to store the invoice_id and payment_id returned in ClubCollect responses and payment notifications, they will be needed to track the status of the payments. As an alternative, the partner can provide a unique external_invoice_number parameter in the payment request and ClubCollect will include it on the response and notifications.

The payment_result can have one of these values:

  • authorized - the payment was successfully processed and accepted by the payment provider

  • refused - the payment could not be processed due to invalid data introduced by the user

  • cancelled - the payee cancelled the payment or the payment session was ended by the payment provider due to inactivity of the payee.

  • pending - the payment is submitted for processing but the payment provider hasn't sent yet the result

  • error - the request was invalid or there was a general error on provider side (payment state is unknown)

Payment notifications

For some online payment methods such as iDEAL, the outcome of the payment request might take several hours to confirm. As soon as ClubCollect receives any update from the payment provider, a payment notification will be sent to the partner to communicate any change in the payment status.

Notifications are sent as HTTPS callbacks (webhooks) to an endpoint on your server. To receive notifications, you need a server that has:

  • An endpoint that can accept a JSON payload in an HTTP POST request.

  • An open TCP port for HTTPS traffic

This endpoint should be communicated to ClubCollect before going live with the payment integration.

The format of the JSON payload sent in the notifications is as follows:

{
  "api_key": "<secret-partner-api-key>",
  "company_id": "<unique-company-id>",
  "invoice_id": "<unique-invoice-id>",
  "external_invoice_number": "<unique-partner-invoice-number>",
  "payment_id": "<unique-payment-id>",
  "payment_method": "ideal",
  "payment_result": "authorized|cancelled"
}

Check status of a payment

GET https://app.clubcollect.com/api/v2/payments/:id

ClubCollect will inform about any changes in the status using payment notifications. This endpoint can be used as a "backup" by the partner to check the current status of a payment in case any notification is dismissed. If at creation time you have provided a custom payment_id then you should use that identifier in this request.
