External Data Preparation

External data in reconciliation refers to any and all documents that hold records of your transaction activity outside of your Blnk Ledger.

​

1. Preparing your data

External data sources have different formats for exporting your data. To prepare your data for reconciliation in Blnk:

1. Download and extract your data from your partners (payment processor, bank, etc.)

2. Transform the extracted data to the following structure:

   Field	Type	Description
   amount	Float	The transaction amount, e.g. 100.50
   currency	String	ISO 4217 currency code, e.g. “USD”
   source	String	Origin of the transaction data, e.g. “Stripe”
   description	String	Transaction details or narration, e.g., “Monthly subscription”
   reference	String	Unique identifier of the transaction, e.g., “ref_128GA6Ag1298ahkj”
   date	ISO 8601	Transaction date and time, e.g., “2023-04-15T14:30:00Z”

3. Export and upload your data in CSV or JSON to Blnk using the endpoint below.

Things to note

Take note of the following when uploading external data to prevent errors or mismatches in your reconciliation:

• Use consistent formatting across all fields.
• Ensure that each transaction has a unique reference value.
• Convert your date value to the UTC timezone to avoid timezone discrepancies.

​

2. Upload your data

Once you have finished preparing your data, you can upload to Blnk with the following endpoint:

curl --location '<https://YOUR_BLNK_INSTANCE_URL/reconciliation/upload>' \\
--header 'Authorization: Bearer YOUR_API_KEY' \\
--form 'file=@"transactions.json"' \\
--form 'source="Stripe"'

{
  "upload_id": "upload_8c700d1b-09c0-4ef4-9ab1-a0decf3d0aa3",
  "status": "success",
  "record_count": 1000,

}
