Exchange your `clientId` and `clientSecret` for a `clientToken` that can be be used in frontend code. `clientToken` will be unusable after the `expiresAt` time, which will normally be after 30 min. 


To try the request in the mock server on the right, substitute username for clientId and password for clientSecret. 

If `reference_id` is passed, it will be passed to the Order object upon when the transaction happens. It can then be used as a filter in the /orders endpoint

Fetch information about an Order once its completed

The `status` of an Order can be one of the following

`Draft` - This is an open or ongoing order

`Processed`* - The payment has been completed.

`Declined`* - The transacation was declined, due to payment method issues

`UserCustody` - Crypto purchased for user but is in Sardine's custodied wallet

`Complete` - The payment is complete and the crypto has been delivered to the user's wallet. A `txHash` will be present to denote successful on chain settlement. 

`Expired` - Order expired before execution

Events marked with an * can also be captured via event handlers on the frontend


### Fetching Orders

Full list of Orders is obtained by making a call to the endpoint with no filters. 


You have multiple options of filtering orders

**1. Filtering by `order_id`**

If a `redirect_url` was passed to the Sardine checkout (e.g. https://crytpoapp.com"), when then transaction is completed, Sardine will redirect the user to this url with an `order_id` appended i.e. https://cryptoapp.com?order_id=73103-erhed-317313

This `order_id` can then be used as a filter on this endpoint

E.g. `/v1/orders/491c113c-4485-47cd-b011-252068b753dc`

**2. Filtering by `referenceId`**
If a `referenceId` was passed in the call to create the `clientToken` for this call, it can now be used to filter for Orders that were created then. 

E.g. `/v1/orders?referenceId=42ead95db5aeb6c`

**3. Filtering by `externalUserId`**

If a `externalUserId` was passed in /auth/client-tokens, it can be used to filter for Orders with that ID. This is useful for associating transactions with a user




**3. Filtering by `startDate` and `endDate`**
If `startDate` or `endDate` are passed in YYYY-MM-DD format, the list of Orders will be filtered to those that were created in this range

E.g. `/v1/orders?startDate=2022-08-01&endDate=2022-08-15`



`paymentStatus` field within the `payment` object in the response can be

- Draft
- Pending

For bank transfers, the value could be

- Sent
- Complete
- Returned
- Failed

For card transactions, the value can be

- Authorized
- Captured
- Declined
- Pending3DS
- Failure3DS
- Voided

Exchange your `clientId` and `clientSecret` for a `clientToken` that can be be used in frontend code. `clientToken` will be unusable after the `expiresAt` time, which will normally be after 30 min.

Post Client Token

Fetch information about an Order once its completed

The `status` of an Order can be one of the following

`Draft` - This is an open or ongoing order

`Expired`* - The user didn't complete the transaction within the `expiration` time

`Processed`* - The payment has been completed.

`Declined`* - The transacation was declined, due to payment method issues

`Cancelled`* - The transaction did not complete, which could be for a number of reasons, as outlined in the reason codes below. 

`Complete`* - The payment is complete and the crypto has been delivered to the user's wallet. A `txHash` will be present to denote successful on chain settlement. 

`Refunded` - The User's payment has been refunded to their original payment method


### For Smart Contract Integrations

Orders might end up in `Cancelled` state, due to a number of reasons, which Sardine will share through a `reasonCode` parameter as part of an `error` object in the Order. After an Order has been Cancelled, it will move to the `Refunded` state

The following reason codes might appear

`NETF` - Network Failure
`PRCC` - Price Change beyond threshold
`RISD` - Risk Decline
`NA` - NFT Not Available


Events marked with an * can also be captured via event handlers on the frontend

Fetch payouts information by `order_id` or `payout_id`

1. By `order_id`

Make a GET request to /payouts/order_id={}

2. By `payout_id`

Make a GET request to /payouts/{payout_id}

Fetch Payout Information

Create a Payout where Sardine will send crypto to specified wallet(s) in specified cryptocurrencies. 

A Payout can be created associated with a corresponding fiat order (where Sardine has also done the fiat processing) or without one (where Sardine does not do the fiat component). 

To trigger Payouts without the fiat processing being done by Sardine, contact your Integration team.

Delete bank account with the corresponding bank account ID

Delete Bank Account

Retrieve result of document verification 

Fetch KYC

Simply populate the appropriate field in the plaidData object. Make sure to fill in the correct field corresponding to the correct Plaid API endpoint. For example, if you call the Plaid transactions API, you should set plaidData.transactionsResponse to be the JSON string containing the response. Note that the response fields in plaidData are all optional and you may populate as many or few as you would like, as long as an authResponse is sent at least once per account.

Important note: You must provide an authResponse at least once per customer bank account so that we can store the mapping from bank account to Plaid account ID.
