# Overview

# Check Issuing Testing

By default, all checks created in the sandbox environment will follow the normal check issuing workflow until they reach a `sent` status. Checks created in sandbox that are in the `sent` status will remain in this status until they expire and are subsequently moved to the `expired` status 180 days after they are created, or until a `stop_payment` request is made on the check which moves it to the `stop_payment_pending` status.

Any sandbox webhooks configured for check create or check updates will automatically work.

## Issuing A Check

##### Example Request to Issue a Check

When a check is issued, it will be in a status of `pending`.

<CodeGroup>
  ```bash bash theme={null}
  curl -u $API_KEY_ID:$API_SECRET_KEY https://api.sandbox.treasuryprime.com/check \
      -H 'Content-Type: application/json' \
      -d '{
            "account_id": "acct_1234567890",
            "amount": "900.00",
            "message": "This is a test message.",
            "memo": "This is a test memo",
            "recipient": {
              "name": "George Washington",
              "address": {
                "city": "Washington",
                "postal_code": "20003",
                "state": "DC",
                "street_line_1": "1600 Pennsylvania Ave.",
                "street_line_2": ""
              }
          }'
  ```
</CodeGroup>

## Updating A Check's Status

Checks in sandbox can only be updated to one of two statuses via the API: `canceled` or `stop_payment_pending`.

### Cancel A Check

Checks can only be `canceled` within 1 hour of it being created while it is in a `pending` status. After this 1-hour window passes, a check is updated from the `pending` status to the `sent` status.

##### Example Request Cancel a Check

<CodeGroup>
  ```bash bash theme={null}
  curl -u $API_KEY_ID:$API_SECRET_KEY https://api.sandbox.treasuryprime.com/check/ch_1234567890 \
      -X PATCH \
      -H 'Content-Type: application/json' \
      -d '{
            "status": "canceled"
          }'
  ```
</CodeGroup>

### Request Stop Payment

A `stop_payment` request can be made to checks that are no longer in a `pending` status and have transitioned into the `sent` status. In sandbox, when a check is moved to the `stop_payment_pending` status it will remain in that status until it is moved to the `expired` status 180 days after the date it was created.

##### Example Request to Request stop\_payment

<CodeGroup>
  ```bash bash theme={null}
  curl -u $API_KEY_ID:$API_SECRET_KEY https://api.sandbox.treasuryprime.com/check/ch_1234567890 \
      -X PATCH \
      -H 'Content-Type: application/json' \
      -d '{
            "status": "stop_payment"
          }'
  ```
