Collect Money

Collect limitation

Simple collection

For example to request 2000 XOF from the +22951010591 Mobile Money wallet, the following code can be used

const momo = require('@chipdeals/momo-api');
momo.setApiKey('test_FOdigzgSopV8GZggZa89');

momo

  .webhook('https://mydomain/payment-status')
  .create(transacrionReference => console.log(transacrionReference));

Make Collection using Callbacks.

momo
  .collect()

Webhook

Webhooks are an important part of your payment integration. They allow Chipdeals notify you about events that happen on your account, such as a successful payment or a failed transaction.

A webhook URL is an endpoint on your server where you can receive notifications about such events. When an event occurs, we'll make a POST request to that endpoint, with a JSON body containing the details about the event, including the type of event and the data associated with it.

Structure of a webhook payload

All webhook payloads follow the same basic structure:

• an event field describing the type of event
• a data object. The contents of this object will vary depending on the event, but typically it will contain details of the event, including:
  • a reference containing the ID of the transaction
  • a status describing the status of the transaction. possible values are success, pending or error
  • a statusMessageCode, containing a specific code that identify an exact state of the transaction. See all statusMessageCode
  • a statusMessage, cantaining an human undertandable descrption of the exact state of the transaction

  • transaction details

Here are some sample webhook payloads for transfers and payments

Implementing a webhook

Creating a webhook endpoint on your server is the same as writing any other API endpoint, but there are a few important details to note:

Verifying webhook signatures When enabling webhooks, you have the option to set a secret hash. Since webhook URLs are publicly accessible, the secret hash allows you to verify that incoming requests are from Chipdeals. You can specify any value as your secret hash, but we recommend something random. We also recommend to store it as an environment variable on your server.

If you specify a secret hash, we'll include it in our request to your webhook URL, in a header called verif-hash. In the webhook endpoint, check if the verif-hash header is present and that it matches the secret hash you set. If the header is missing, or the value doesn't match, you can discard the request, as it isn't from Chipdeals.

Responding to webhook requests To acknowledge receipt of a webhook, your endpoint must return a 200 HTTP status code. Any other response codes, including 3xx codes, will be treated as a failure. We don't care about the response body or headers.

Be sure to enable webhook retries on your dashboard. If we don't get a 200 status code (for example, if your server is unreachable), we'll retry the webhook call every 90 minutes for the next 36 hours.

  }
}

Callback

Call back allow to be notified in your code as soon as events happen about your transaction, such as a successful payment or a failed transaction.

When an event occurs, we'll call concerned callback function and will pass a single parametter containing the details about the event, the state of the transaction and the data associated with it.

Structure of callback data

All webhook payloads (except virtual card debits) follow the same basic structure:

• an event field describing the type of event
• a data object. The contents of this object will vary depending on the event, but typically it will contain details of the event, including:
  • a reference containing the ID of the transaction
  • a statusMessageCode, containing a specific code that identify an exact state of the transaction. See all statusMessageCode
  • a statusMessage, cantaining an human undertandable descrption of the exact state of the transaction
  • transaction details

More Info

Collection and disburssement parametters

- phoneNumber parameter

You specify the phoneNumber of a collection with method from(phoneNumber: sting)

And for a disbursement you specify phoneNumber with method to(phoneNumber: sting)

Those methode are locking for a string containing the phone number of the money sender for collection and the money recipient for disbursement.

The PhoneNumber should respect this format:

XXXOOOOOOOO

where the three X represent the country phone préfix (229 | 237 for example), and the O are the phone number in the country. The number of O can change with the country but the prefix should be 3.

- currency parameter

You specify the currenct of a transaction with the method currency(currency: string)

The currency should be a string of 3 character.

If you add a currency that is not the currency localy used in the country of the phone number of the transaction, we will convert the amount of the transaction into local currency.

Our conversion rate evoluate like the market.

- amount parameter

You specify the amount of a transaction with the method amount(transactionAmount: number)

It is a number.

We will check if the currency that you specify for the transaction is the local currency of the phone number's country and then we will convert the amount into local currency before perform the transaction with the customer

- fistName and lastName parameters

You respectively specify firstName and lastName with methods firstName(senderFirstName: string) and lastName(senderLastName: string)

Those parametters are required to perform secured collection request.

Disbursement doesn't need them.

If you make 3 request per day with unspesified firstName and | or lastName we will block the 4th and the other. We recommand you to specify fisrtName and lastName for all your collection request.

In sandbox test, you have no probleme with firstName and lastName specification, you can do as you like But be careful for Live

Status Message Code

Sandbox tests

You can use your test apikey or all users test apikey : test_FOdigzgSopV8GZggZa89 to make sandbox requsts.

All valid phone number you used in sandbox will send you valid responses as it was the live mode.

For exemple, if you use the phone number 22951010581 you will get a response with status message code 201 (what means pending see more here). Some seconds laters, you will get status messages codes 202, 203 and 200 (200 means success).

It is the same thing for others phone number with a small exception to allow errors case handling by implementor.

Limitation

Unsecured collect limitation

When you are making a collection request, you have posibility to specify or not the payer's fistname and lastname. By not specifying firstName and lastName, you can make quick test.

But when firstName and lastName are not specified your collection request is not secured. And you are alowed to perform at most 3 unsecured collection resquest per day. More request will be just blocked.

You cannot perform unsecured collection request for more than 500 XOF.
