I'm using Braintree payment gateway and having issues when tying to make a payment through REST API. I am calling carts/mine/payment-information endpoint with following values.

Header:

Authorization: Bearer customer-token
Content-type: application/json

Body:

 "paymentMethod": 
 "po_number": "",
 "method": "braintree",
 "additional_data": 
 "cc_last4":"1111", 
 "store_in_vault":true, 
 "payment_method_nonce":"nonce-goes-here", 
 "cc_token":"", 
 "device_data":"", 
 "cc_type":"Visa", 
 "cc_exp_year":"2055", 
 "cc_exp_month":"01" 
 ,
 "extension_attributes": 
 "agreement_ids": [
 "string"
 ]
 
 ,
 "billingAddress": 
 "id": 0,
 "region": "Victoria",
 "region_id": 546,
 "region_code": "VIC",
 "country_id": "AU",
 "street": [
 "Main St"
 ],
 "company": "Company Name",
 "telephone": "987654321",
 "fax": "",
 "postcode": "3000",
 "city": "Melbourne",
 "firstname": "Firstname",
 "lastname": "Lastname",
 "middlename": "Middlename",
 "prefix": "Mr",
 "suffix": "",
 "vat_id": "",
 "customer_id": 0,
 "email": "name@domain.name",
 "same_as_billing": 0,
 "customer_address_id": 0,
 "save_in_address_book": 0,
 "extension_attributes": ,
 "custom_attributes": 
 
 

I have generated a braintree token and used that token to generate the nonce. With the use of nonce, I was able to create a Braintree transaction as below.

 $result = Braintree_Transaction::sale([
 'amount' => $transactionAmount,
 'paymentMethodNonce' => $nonceFromTheClient,
 'options' => [
 'submitForSettlement' => True
 ]
 ]);

The transaction gets successful but when I try to place an order on Magento using my transaction details, I keep getting the following error.

Transaction has been declined. Please try again later

Can anyone advise me what's wrong with my process/ request please?

Thanks!

Here how Braintree integration looks like (https://developers.braintreepayments.com/start/overview)

So you need do the following

1) Get client token from Magento server. I didn't find rest endpoint for it so I've created a custom extension for this purpose (https://github.com/troublediehard/mma-customapi)

2) Then use sdk and token to get nonce from you card

3) And send your request with nonce data like this

 paymentMethod: 
 method: 'braintree',
 additional_data: 
 payment_method_nonce: nonce,
