The STARTPROCESS workflow application lets you launch a new request with the corresponding parameters. It provides a simple solution for inter-process communications.

There are three ways to use STARTPROCESS to launch a new request:

- Process ID

- Process name with process version

- Process name with test

### Process parameters

| Parameter | Type | Direction | Description |
| --- | --- | --- | --- |
| `PROCESS_ID` | Numeric | IN | Process ID of the request to launch (to be used independently, without the other parameters) |
| `PROCESS_NAME` | Text | IN | Process name of the request to launch |
| `PROCESS_VERSION` | Numeric | IN | Version of the process to launch |
| `TEST` | Text | IN | Test mode: `Y` (launch a test version) or `N` (launch the active version) |

### Optional parameters

| Parameter | Type | Direction | Description |
| --- | --- | --- | --- |
| `REQUEST_ID` | Numeric | OUT | Returns the ID of the new request |
| `IMPERSONATE_USERNAME` | Text | IN | Username of the impersonating user |

You can define other parameters as needed in the workflow process to launch; for example `COMPANY` (text type IN parameter), e.g. `ACME_COMPANY` .

### Examples

#### Process ID

| Parameter | Type | Direction | Description |
| --- | --- | --- | --- |
| `PROCESS_ID` | Numeric | IN | Send value of `MY_PROCESS_ID` (a numeric process data containing the ID of the process to start, e.g. `1320` ) |

#### Process name with process version

| Parameter | Type | Direction | Description |
| --- | --- | --- | --- |
| `PROCESS_NAME` | Text | IN | Send value of `MY_PROCESS_NAME` (a text process data containing the name of the process to start, e.g. `LEAVE_APPLICATION` ) |
| `PROCESS_VERSION` | Numeric | IN | Send value of `MY_PROCESS_VERSION` (a numeric process data containing the version number of the process to start, e.g. `2` ) |

#### Process name with test

| Parameter | Type | Direction | Description |
| --- | --- | --- | --- |
| `PROCESS_NAME` | Text | IN | Send value of `MY_PROCESS_NAME` (a text process data containing the name of the process to start, e.g. `LEAVE_APPLICATION` ) |
| `TEST` | Text | IN | Send value of `MY_TEST` (e.g. `Y` ) |
