<Note>
  If you're using the auto-provisioned `Enterprise Core` instance included with your Production License deployment, set the base URL to: `https://ENTERPRISE_PUBLIC_URL/core`.

  If you're connecting to a different Core instance, use the publicly accessible base URL for that instance instead.
</Note>

### Authorization

If set, the API uses an API key for authentication. Include the following header in your requests: `X-blnk-key: <api-key>`.

Replace `<api-key>` with your secret API key. Ensure the key is kept secure and not exposed in public repositories or client-side code.

See also: [Scoped API keys](/api-keys/overview) and [Secure your Blnk server](/advanced/secure-blnk).

### Body

<Info>**Important tip:** To apply multiple sources, Blnk uses the `sources` array instead of the conventional `source` parameter in [Record transaction](/reference/create-transaction).</Info>

<ParamField body="precise_amount" type="integer">
  The transaction amount in its smallest unit (recommended). Include the corresponding `precision` value. See [Transaction precision](/transactions/precision).

  <Warning>
    Either `precise_amount` or `amount` should be provided, not both.
  </Warning>
</ParamField>

<ParamField body="amount" type="integer | float">
  The transaction amount as a float. Blnk multiplies `amount` by `precision` to store `precise_amount`.
</ParamField>

<ParamField body="currency" type="string" required>
  The currency of the transaction amount is in.
</ParamField>

<ParamField body="precision" type="integer" default="1" required>
  Precision for the transaction's currency. Also see: [Precision](/transactions/precision).
</ParamField>

<ParamField body="reference" type="string" required>
  The unique transaction reference number for the transaction. If empty, Blnk auto-creates one.
</ParamField>

<ParamField body="sources" type="array" required>
  Lists the sources for the transaction. Each source includes:

  <Expandable>
    <ParamField body="identifier" type="string" required>
      The transaction id of the source.
    </ParamField>

    <ParamField body="distribution" type="string" required>
      Specifies how much should be deducted from the source. It can either be:

      * a fixed amount (`"240.23"`),
      * a percentage (`"20%"`) or
      * the remaining amount (`"left"`).
    </ParamField>

    <ParamField body="precise_distribution" type="string">
      When a transaction uses `precise_amount`, use `precise_distribution` in place of `distribution` only for sources that specify an exact value.  (e.g., `"37841507139655800"`).

      <Note>Accepts only integers values in the string</Note>
    </ParamField>
  </Expandable>
</ParamField>

<ParamField body="destination" type="string" required>
  The balance receiving the amount. `@` prefix indicates that the balance is an [internal balance](/balances/internal-balances).
</ParamField>

<ParamField body="scheduled_for" type="string">
  Indicates the date and time of a scheduled transaction, e.g., `"2024-02-20 05:28:03"`.
</ParamField>

<ParamField body="allow_overdraft" type="boolean" default="false">
  Specifies whether the transaction should proceed even if the source’s balance is insufficient. If enabled and the source has less than the required amount, the balance will become negative. See also: [Overdrafts](/transactions/overdrafts)
</ParamField>

<ParamField body="inflight" type="boolean" default="false">
  Specifies that the transaction should be held until certain conditions are met. See also: [Create inflight](/transactions/inflight/creating-inflight).
</ParamField>

<ParamField body="inflight_expiry_date" type="string">
  Specifies the date and time when an inflight transaction should expire. Once expired, the transaction is voided and the amount is rolled back.
</ParamField>

<ParamField body="inflight_commit_date" type="string">
  When **`inflight`** is true, the date and time when Blnk should automatically commit the inflight transaction. See [Schedule inflight commits](/transactions/inflight/updating-inflight#schedule-inflight-commits).
</ParamField>

<ParamField body="atomic" type="boolean" default="false">
  When false, Blnk processes each destination independently.

  Valid destinations are `APPLIED`, while invalid ones are `REJECTED`. When true, all destinations must succeed for the split to be processed. If any destination fails, no credits are `APPLIED`, and succesful inflights are set to `VOID`.

  See [Atomic split processing](/transactions/multiple-sources#atomic-split-processing).
</ParamField>

<ParamField body="meta_data" type="object">
  Additional metadata of the transaction.
</ParamField>

### Response

<Info>All parameters from the request body also mean the same in the corresponding response JSON.</Info>

<ResponseField name="precise_amount" type="integer">
  The amount stored in the ledger in its smallest unit. See [Precision](/transactions/precision).
</ResponseField>

<ResponseField name="transaction_id" type="string">
  Unique id of the transaction.
</ResponseField>

<ResponseField name="parent_transaction" type="string">
  The transaction ID of the parent transaction. A parent transaction is one that impacts the creation of a new transaction, such as an inflight transaction, a scheduled transaction, or similar.

  For instance, refunding a sample transaction A creates a new transaction B; therefore A is the parent transaction of B.
</ResponseField>

<ResponseField name="status" type="string">
  The status of the transaction. See the following: [Transaction statuses](/transactions/transaction-lifecycle#statuses).
</ResponseField>

<ResponseField name="hash" type="string">
  Per-row SHA-256 fingerprint of the transaction's core details. The optional global hash chain is separate and not returned in API responses. Learn more: [Transaction hashing](/transactions/hash)
</ResponseField>

<ResponseField name="created_at" type="string">
  Indicates the date & time the transaction was created.
</ResponseField>

<ResponseField name="meta_data" type="User Object">
  Additional metadata of the transaction.
</ResponseField>
