## Supported operations

The Temenos Transact Connector supports the following operations from the Grand Central Unified API specification:

### Deposit account

| **Operation**                | **Endpoint**                                     |
| :--------------------------- | :----------------------------------------------- |
| Create a deposit account     | `POST /deposits`                                 |
| Get deposit account details  | `GET /deposits/{depositId}`                      |
| Get deposit account balances | `GET /deposits/balances?depositIds={depositIds}` |
| Close a deposit account      | `PATCH /deposits/{depositId}/close`              |

<Note>
  The create deposit operation supports current accounts, savings accounts, and term deposits. The connector automatically routes to the correct Temenos endpoint based on the product line associated with the product ID.
</Note>

### Deposit transactions

| **Operation**                          | **Endpoint**                                 |
| :------------------------------------- | :------------------------------------------- |
| Get transactions for a single account  | `GET /deposits/{depositId}/transactions`     |
| Get transactions for multiple accounts | `POST /deposits/transactions`                |
| Get a transaction by ID                | `GET /deposits/transactions/{transactionId}` |

<Note>
  `POST /deposits/transactions` accepts a request body containing a list of deposit IDs. Use this endpoint to retrieve transactions for multiple accounts in a single request.
</Note>

### Loan account

| **Operation**             | **Endpoint**                                |
| :------------------------ | :------------------------------------------ |
| Create a loan account     | `POST /loans`                               |
| Get loan balances         | `GET /loans/balances?loanIds={loanIds}`     |
| Get loan details          | `GET /loans?loanIds={loanIds}`              |
| Get amortization schedule | `GET /loans/{loanId}/amortization-schedule` |

### Loan transactions

| **Operation**                            | **Endpoint**                              |
| :--------------------------------------- | :---------------------------------------- |
| Get loan transactions for a single loan  | `GET /loans/{loanId}/transactions`        |
| Get loan transactions for multiple loans | `POST /loans/transactions`                |
| Get a loan transaction by ID             | `GET /loans/transactions/{transactionId}` |

<Note>
  The connector doesn't support retrieving a single loan transaction by ID. `GET /loans/transactions/{transactionId}` returns HTTP `501` with error code `GC023`. To retrieve loan transactions, use `GET /loans/{loanId}/transactions` or `POST /loans/transactions`, then filter by transaction ID on the caller side.
</Note>

### Party

| **Operation**                  | **Endpoint**                                 |
| :----------------------------- | :------------------------------------------- |
| Create party                   | `POST /parties`                              |
| Update party details           | `PUT /parties/{partyId}`                     |
| Get party details              | `GET /parties/{partyId}`                     |
| Search party                   | `GET /parties/search?{search criteria}`      |
| Get accounts by party ID       | `GET /parties/{partyId}/accounts`            |
| Party Relationship Maintenance | `POST /parties/{partyId}/party-relationship` |

<Info>
  Party search supports the following criteria:

  | Parameter                 | Description                   |
  | :------------------------ | :---------------------------- |
  | `partyName`               | Full or partial party name    |
  | `firstName`               | Party's first name            |
  | `middleName`              | Party's middle name           |
  | `familyName`              | Party's family name           |
  | `organisationName`        | Organisation name             |
  | `partyId`                 | Unique party identifier       |
  | `taxIdentificationNumber` | Tax identification number     |
  | `phoneNumber`             | Party's phone number          |
  | `emailId`                 | Party's email address         |
  | `birthDate`               | Party's date of birth         |
  | `depositAccountId`        | Associated deposit account ID |

  Search results include relationship details, address information, and account associations for each matching party.
</Info>

### Product matching

| Operation                                  | Method                                         | Endpoint                |
| :----------------------------------------- | :--------------------------------------------- | :---------------------- |
| Simulate maturity calculation for deposits | <span className="http-method-post">POST</span> | `/maturity-calculation` |

<Note>
  The maturity calculation request accepts party information, product IDs, investment amount, tenor, renewal terms, and interest payout frequency. The response includes the projected maturity date and amount, total interest earnings, projected tax withholding, payout schedule, and early withdrawal terms. The connector runs a read-only Temenos deposit simulation and enriches the result with the arrangement simulation schedule. No arrangement is booked. The Grand Central product matching API also defines `POST /eligibility` for product eligibility checks; this connector does not implement that endpoint.
</Note>
