General use
Twikey has put in place several services enabling software partners, companies with own ERP or CRM systems, banks and other 3rd parties to exchange information. This page describes the different calls that are available to you. The calls allow integration in a number of ways.
Since there are numerous ways a company can allow its customers to pay, we also provided a couple of high level use-cases to get you up and running in no time.
All exchanges require a valid AuthorizationToken passed on as a header named "Authorization". The AuthorizationToken can be retrieved via the login call and is valid for 24h. We suggest that the call to the login is done when the actual call you wish to make is returning a 401. This way you don't need to handle the lifecycle of your token yourself.
Exchanges can be in both JSON & XML responses. By default they will be in JSON, but by giving the "Accept" header a value of 'application/xml', you can get an xml payload.
Errors can be divided into 2 categories. The first category are errors based on user input for which we return a 400 error with the code of the error mentioned in the response header "ApiError'. The translated error can be found in the body of the required exchange. The language is provided by the "Accept-Language" header or defaults to English. The second category of errors is one that you normally shouldn't run into a lot. In this case we return a 500 error which means that something went wrong on our end. We'll probably already know about it when you see the error.
Sample use cases
The fitness scenario
Imagine you're going to the fitness where you exercise every once in a while. Since this doesn't come free you pay a monthly subscription fee. This subscription fee is a recurring payment (we'll come back to that later). But since all those exercises get you thirsty, you want to drink there too. But of course, there are hotter and colder days. So how much you drink can vary.
Regardless of what you consume, the fitness wants to get paid. But you'd like to avoid getting out your wallet when you're all sweaty. So your fitness made the great decision to use direct debits to allow you to pay. At the end of the month they add the recurring amount to the one-off's (the drinks). They send the payment request to the bank. Everyone's happy and relax.
What did the fitness do to achieve this relaxed way of working:
First of all, everything starts with a mandate. When a customer enrolls at the fitness he fills in the details for the internal bookkeeping of the fitness. The same information is sent to the prepare call. This returns a URL (representing an unsigned mandate) that opens up after entering all details in the enrollment screen. Since the fitness has an internal subscription number they want to use to track payments and have multiple subscriptions (eg. with and without personal trainer) they add both parameters in the prepare call. Making it visible in the mandate overview.
Once the customer filled in the account info and signed the mandate he's sent back to the fitness website with a "thank you" message. When a customer ask for a drink at the bar, the cash register calls the transaction endpoint with the details and amount. These are one-off transactions. Recurring transactions can either be handled the same way or if a subscription parameter was added in the prepare call, a recurring transaction is automatically added every month to get this subscription paid. At the end of each month, the file is created and sent to the bank manually via the collect call or automatically every night. Your bill is paid and the bank sends you the money. When the bank sends us back the account information, it is marked in your transaction overview that the transaction was paid. This information can be retrieved by the payment call. This call returns all new payment information since the last call. If a payment didn't succeed, you can configure what will happen next in the interface in the dunning section.
The parking app scenario
Because my customers don't like running in the rain looking for a parking meter while there's an app for that. How can I use Twikey to get my parking fees paid? First of all, you need a mandate . There are three possible options to have this mandate signed:
Use an in-app browser with the link retrieved via the prepare call Use the sign call to invite the user to sign via an sms confirmation Use the sign call adding the manual signature as a png-image in the payload Once the mandate is signed, in-app purchases can be sent from the backend of the app, collected the same way as mentioned in the fitness scenario.
The (off-line) webshop scenario
I have a shop where people come in physically but I also have a webshop. I want people who signed a mandate (either online via the above flow or physically) to be able to purchase something from the online shop without requiring them to use their credit card and if possible give them the sameconvenience in the physical shop. This way I can send them an invoice every month by only registering their purchases and collecting the payment via direct debit.
In the past, I had to send out all invoices and patiently waited for them to be paid. Since I'm not the most patient person on earth and even a bit chaotic at times, I'd rather collect the money directly from my customers. This way they can't forget to pay and I don't need to remind them to do so. How convenient this is for both my customers and I.
Authentication
Login
When using the API the login call will provide you with an AuthorizationToken, which is to be send upon every subsequent call (via the authorization header) in order to use the api. If the creditor opted for enhanced security, the private key allows the generation of a Time-based One-time password. See Appendix C of the Creditor API documentation for a more detailed explanation or sample code on how to calculate this OTP (samples in various languages are available).
Normally this call is made on request of another call that returned a 401 (UNAUTHORIZED) indicating that there was no session token or that it expired.
Requires an API Token which can be found in the Twikey Creditor Dashboard
curl -X POST https://api.twikey.com/creditor /
-d apiToken=**API Token**$host = "https://api.twikey.com";
$apitoken = "**API_TOKEN**";

HTTP Response
| Code | Description |
|---|---|
| 200 | For security reasons, the http status is always 200, however for returning error codes specific to the call 2 additional response headers were added "ApiError" and "ApiErrorCode" which are added on every response that contains errors. Notible exceptions are authentication errors and authorisation errors that don't have these 2 headers. |

Mandate
Invite a customer
Necessary to start with an eMandate. The end-result is a signed or protected shortlink that will allow the end-customer to sign a mandate. The (short)link can be embedded in your website or in an email or in a paper letter. We advise to use the shortlink as the data is not exposed in the URL's. The parameters are as described in detail on the page "Create contracts".
After signing the end-customer is either presented with a thank-you page or is redirected to an exit url defined on the template. This url can contain variables that are filled in depending on the outcome. See exit urls

Sign a mandate
Create a contract with an invitation/signature directly via API. Note that this call can require different parameters depending on the method of signature. All parameters are described in Create contracts When enabled for your contract it is possible to negiotiate mandates with their signature directly via API. Depending on the method the set of required parameters and/or handling may differ. Methods currently supported :
- sms: require the mobile parameter
- digisign a base64 encoded png should be provided as payload. (max 150 k)
- Challenge/Response

Update Feed
Returns a List of all updated mandates (new, changed or cancelled) since the last call. From the moment there are changes (eg. a new contract/mandate or an update of an existing contract) this call provides all related information to the creditor. The service is initiated by the creditor and provides all MRI information (and extra metadata) to the creditor. This call can either be triggered by a callback once a change was made or periodically when no callback can be made. This information can serve multiple purposes:
- Updating a CRM system to take appropriate actions (eg. call the customer on cancel..)
- Integrate the info in an ERP system to create the correct SDD files (in case of mandates)
If your system is out of sync or the full mandate database needs to be refreshed an optional "X-RESET" header can be passed. The format can be a timestamp like "2015-08-20T13:02:03Z" or a specific MandateNumber. After that you will receive (all) mandate updates since that time again.
In order too avoid polling, a #19-callbacks can be setup to notify the client when new information is available. This hook can be configured in the Settings > API.
There are 3 possible updates.
- The first one is when a new signed mandate is available.
- The second is an amendment on a mandate (like address change). Indicated by the existence of an "AmdmntRsn".
- Last one is a cancellation of a mandate. Indicated by the existence of a "CxlRsn"

Cancel a mandate
A contract can be cancelled by either debtor or creditor, this can be done via the website or the api. However, there may be circumstances in which the creditor receives the cancel not through Twikey. In order to avoid extra costs & stale information, Twikey requires the update of its systems. The creditor, the creditor bank or the debtor bank, can initiate this request. Afterwards the update is distributed to all parties.

Payments
The payment information can be retrieved in 2 ways. This can either be done by polling the transaction feed or by the status of the collection. Both can be polled periodically or triggered by a callback.

}This endpoint allows to retrieve a list of all the transactions for which new payment information has been received since the last call. This endpoint doesn't require any parameters. If we receive an error from the bank, we mark the transaction with status "error" or "paid". We also add a final flag which can either be true or false. True (being final) means that we can't do anything with it anymore. This could be the case for paid transactions as well as for errors like debtor deceased. An action will be required on your part. False means that we still have actions pending to debit the debtor's account.

}This endpoint allows to retrieve a list of SDD's for which new payment information is given. If the parameter 'id' is passed, it will also return the details of the mandates contained in the referenced SDD. If the 'detail' parameter is passed (regardless of its value) then the call with the 'id' parameter is obsolete as the details are included in the general call. In case we receive an error from the bank, we mark the transaction with status "error" or "paid", but on top of it we add a final flag which will either be true or false. True (being final) means that we can't do anything with it anymore. This could be the case for paid transactions as well as for errors like debtor deceased. An action would be required from your part. False means that we still have actions pending to debit the debtor's account.
Create paymentlink
Sometimes the customer can't pay via direct debit from his regular account even though he wants to pay. To help that customer pay his debt, we allow you to create a payment link (with or without expiry).

Webhooks
In order to reduce the number of polling requests, one can opt to implement a webhook endpoint and use this as a way to trigger polling requests. The endpoint is set in the API section of the settings screen and will convey information about various events in Twikey. The call is done via a simple GET with basic (non-sensitive) parameters eg. http://my.company.com/callback?type=contract&mandateNumber=MNDT123&state=signed...
In order to verify that the request is indeed coming from Twikey you can verify the headers 'apiToken' and optionally 'otp' which should hold the same values as you'd use for the login.
Note that the url to be given in the interface is without parameters since these are filled up depending on the type.
type=contract
Triggered when something happens to the mandate. Activation events (when a mandate becomes suspended or gets resumed) will be included in the event=Update with the reason being either 'resumed" or 'suspended'
- mandateNumber : Mandatenumber
- contractNumber : Contract number
- state : New state of the mandate
- name : Name of the mandate
- event : Name of the event
- reason : Optional reason
curl -H "apiToken=MyToken" https://example.com/callback \
-d type=contract \
-d reason=resumed \
-d mandateNumber=CORE01 \
-d name=MyMandate \
-d contractNumber=454 \
-d state=SIGNED \
-d event=Updatetype=transaction
Triggered when a new transaction is being added.
Extra parameters:
- id : Twikey id of the transaction being added
- ref : Your reference of the transaction
- msg : Message of the transaction
type=plan
Triggered when a plan was executed
Extra parameters:
- name : Name of the plan that was executed
type=payment
Triggered when a batch of payments were received. Note that this is triggered for the batch and not per transaction as it could cause a flood of requests.
No parameters to avoid hammering your site when new transaction feedback is received
This is also triggered when a paymentlink was updated to either paid, rejected or expired. In that case you will receive the initial id, ref and status back.
type=dunning
Triggered when a dunning action was executed for a failed transaction
Extra parameters:
- mandateNumber : Mandatenumber
- txIds : Transaction ID
Exit Url
An alternative to a webhook can be the exit url or the page where the end-user is being redirected to after signing. This is a thank-you page or a redirect to an exit url defined on the template. This url can contain variables that are filled in depending on the outcome. The variables can either be positional of named.
- {0} / {{mandateNumber}} : mandate number
- {1} / {{status}} : status (ok = signed)
- {2} / {{account}} : iban/bic encrypted wih key privateKey+contract.getMandateNumber()
- {3} / {{s}} : signature over mandate and status separated by a slash (hex encoded)
- {4} / {{token}} : token (optional: if passed in the incoming url)
Some of the exceptional statusses can be (but not limited to):
- cancel: User cancelled the session
- invalidUrl: Invalid url or signature
- inactiveTmpl: Template was inactive
- alreadySigned: Already signed
- ...
In order to be sure that the return call is coming from Twikey, it's strongly recommended to verify the signature to the exit url. Calculation of the signature is done as described in Appendix E.
eg. an exit url with the following value
http:///website.com/{0}/{1}/{3}
or
http:///website.com/{{mandateNumber}}/{{status}}/{{s}}
would be expanded to if the end-customer signed
