Summary
Banking API: Codat's standardized API for accessing banking data.
New to Codat?
Our Banking API reference is relevant only to our existing clients. Please reach out to your Codat contact so that we can find the right product for you.
Codat's Banking API allows you to access standardised data from over bank accounts via third party providers.
Standardize how you connect to your customers’ bank accounts. Retrieve bank account and bank transaction data in the same way via our partnerships with Plaid and TrueLayer.
Endpoints
Endpoints | Description |
---|---|
Accounts | Where payments are made or received, and bank transactions are recorded. |
Account balances | Balances for a bank account including end-of-day batch balance or running balances per transaction. |
Transactions | An immutable source of up-to-date information on income and expenditure. |
Transaction categories | Hierarchical categories associated with a transaction for greater contextual meaning to transaction activity. |

Retries
Some of the endpoints in this SDK support retries. If you use the SDK without any configuration, it will fall back to the default retry strategy provided by the API. However, the default retry strategy can be overridden on a per-operation basis, or across the entire SDK.
To change the default retry strategy for a single API call, simply provide a retry.Config
object to the call by using the WithRetries
option:
package main
import (
"context"
"github.com/codatio/client-sdk-go/previous-versions/banking"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/operations"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/shared"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/retry"
"log"
"pkg/models/operations"
)
func main() {
s := banking.New(
banking.WithSecurity(shared.Security{
AuthHeader: "Basic BASE_64_ENCODED(API_KEY)",
}),
)
ctx := context.Background()
res, err := s.AccountBalances.List(ctx, operations.ListAccountBalancesRequest{
CompanyID: "8a210b68-6988-11ed-a1eb-0242ac120002",
ConnectionID: "2e9d2c44-f675-40ba-8049-353bfcb5e171",
OrderBy: banking.String("-modifiedDate"),
Page: banking.Int(1),
PageSize: banking.Int(100),
Query: banking.String("id=e3334455-1aed-4e71-ab43-6bccf12092ee"),
}, operations.WithRetries(
retry.Config{
Strategy: "backoff",
Backoff: &retry.BackoffStrategy{
InitialInterval: 1,
MaxInterval: 50,
Exponent: 1.1,
MaxElapsedTime: 100,
},
RetryConnectionErrors: false,
}))
if err != nil {
log.Fatal(err)
}
if res.AccountBalances != nil {
// handle response
}
}
If you'd like to override the default retry strategy for all operations that support retries, you can use the WithRetryConfig
option at SDK initialization:
package main
import (
"context"
"github.com/codatio/client-sdk-go/previous-versions/banking"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/operations"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/shared"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/retry"
"log"
)
func main() {
s := banking.New(
banking.WithRetryConfig(
retry.Config{
Strategy: "backoff",
Backoff: &retry.BackoffStrategy{
InitialInterval: 1,
MaxInterval: 50,
Exponent: 1.1,
MaxElapsedTime: 100,
},
RetryConnectionErrors: false,
}),
banking.WithSecurity(shared.Security{
AuthHeader: "Basic BASE_64_ENCODED(API_KEY)",
}),
)
ctx := context.Background()
res, err := s.AccountBalances.List(ctx, operations.ListAccountBalancesRequest{
CompanyID: "8a210b68-6988-11ed-a1eb-0242ac120002",
ConnectionID: "2e9d2c44-f675-40ba-8049-353bfcb5e171",
OrderBy: banking.String("-modifiedDate"),
Page: banking.Int(1),
PageSize: banking.Int(100),
Query: banking.String("id=e3334455-1aed-4e71-ab43-6bccf12092ee"),
})
if err != nil {
log.Fatal(err)
}
if res.AccountBalances != nil {
// handle response
}
}
Error Handling
Handling errors in this SDK should largely match your expectations. All operations return a response object or an error, they will never return both. When specified by the OpenAPI spec document, the SDK will return the appropriate subclass.
Error Object | Status Code | Content Type |
---|---|---|
sdkerrors.ErrorMessage | 400,401,402,403,404,409,429,500,503 | application/json |
sdkerrors.SDKError | 4xx-5xx | / |
Example
package main
import (
"context"
"errors"
"github.com/codatio/client-sdk-go/previous-versions/banking"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/operations"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/sdkerrors"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/shared"
"log"
)
func main() {
s := banking.New(
banking.WithSecurity(shared.Security{
AuthHeader: "Basic BASE_64_ENCODED(API_KEY)",
}),
)
ctx := context.Background()
res, err := s.AccountBalances.List(ctx, operations.ListAccountBalancesRequest{
CompanyID: "8a210b68-6988-11ed-a1eb-0242ac120002",
ConnectionID: "2e9d2c44-f675-40ba-8049-353bfcb5e171",
OrderBy: banking.String("-modifiedDate"),
Page: banking.Int(1),
PageSize: banking.Int(100),
Query: banking.String("id=e3334455-1aed-4e71-ab43-6bccf12092ee"),
})
if err != nil {
var e *sdkerrors.ErrorMessage
if errors.As(err, &e) {
// handle error
log.Fatal(e.Error())
}
var e *sdkerrors.SDKError
if errors.As(err, &e) {
// handle error
log.Fatal(e.Error())
}
}
}
Server Selection
Select Server by Index
You can override the default server globally using the WithServerIndex
option when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:
# | Server | Variables |
---|---|---|
0 | https://api.codat.io | None |
Example
package main
import (
"context"
"github.com/codatio/client-sdk-go/previous-versions/banking"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/operations"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/shared"
"log"
)
func main() {
s := banking.New(
banking.WithServerIndex(0),
banking.WithSecurity(shared.Security{
AuthHeader: "Basic BASE_64_ENCODED(API_KEY)",
}),
)
ctx := context.Background()
res, err := s.AccountBalances.List(ctx, operations.ListAccountBalancesRequest{
CompanyID: "8a210b68-6988-11ed-a1eb-0242ac120002",
ConnectionID: "2e9d2c44-f675-40ba-8049-353bfcb5e171",
OrderBy: banking.String("-modifiedDate"),
Page: banking.Int(1),
PageSize: banking.Int(100),
Query: banking.String("id=e3334455-1aed-4e71-ab43-6bccf12092ee"),
})
if err != nil {
log.Fatal(err)
}
if res.AccountBalances != nil {
// handle response
}
}
Override Server URL Per-Client
The default server can also be overridden globally using the WithServerURL
option when initializing the SDK client instance. For example:
package main
import (
"context"
"github.com/codatio/client-sdk-go/previous-versions/banking"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/operations"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/shared"
"log"
)
func main() {
s := banking.New(
banking.WithServerURL("https://api.codat.io"),
banking.WithSecurity(shared.Security{
AuthHeader: "Basic BASE_64_ENCODED(API_KEY)",
}),
)
ctx := context.Background()
res, err := s.AccountBalances.List(ctx, operations.ListAccountBalancesRequest{
CompanyID: "8a210b68-6988-11ed-a1eb-0242ac120002",
ConnectionID: "2e9d2c44-f675-40ba-8049-353bfcb5e171",
OrderBy: banking.String("-modifiedDate"),
Page: banking.Int(1),
PageSize: banking.Int(100),
Query: banking.String("id=e3334455-1aed-4e71-ab43-6bccf12092ee"),
})
if err != nil {
log.Fatal(err)
}
if res.AccountBalances != nil {
// handle response
}
}
Custom HTTP Client
The Go SDK makes API calls that wrap an internal HTTP client. The requirements for the HTTP client are very simple. It must match this interface:
type HTTPClient interface {
Do(req *http.Request) (*http.Response, error)
}
The built-in net/http
client satisfies this interface and a default client based on the built-in is provided by default. To replace this default with a client of your own, you can implement this interface yourself or provide your own client configured as desired. Here's a simple example, which adds a client with a 30 second timeout.
import (
"net/http"
"time"
"github.com/myorg/your-go-sdk"
)
var (
httpClient = &http.Client{Timeout: 30 * time.Second}
sdkClient = sdk.New(sdk.WithClient(httpClient))
)
This can be a convenient way to configure timeouts, cookies, proxies, custom headers, and other low-level configuration.
Authentication
Per-Client Security Schemes
This SDK supports the following security scheme globally:
Name | Type | Scheme |
---|---|---|
AuthHeader | apiKey | API key |
You can configure it using the WithSecurity
option when initializing the SDK client instance. For example:
package main
import (
"context"
"github.com/codatio/client-sdk-go/previous-versions/banking"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/operations"
"github.com/codatio/client-sdk-go/previous-versions/banking/pkg/models/shared"
"log"
)
func main() {
s := banking.New(
banking.WithSecurity(shared.Security{
AuthHeader: "Basic BASE_64_ENCODED(API_KEY)",
}),
)
ctx := context.Background()
res, err := s.AccountBalances.List(ctx, operations.ListAccountBalancesRequest{
CompanyID: "8a210b68-6988-11ed-a1eb-0242ac120002",
ConnectionID: "2e9d2c44-f675-40ba-8049-353bfcb5e171",
OrderBy: banking.String("-modifiedDate"),
Page: banking.Int(1),
PageSize: banking.Int(100),
Query: banking.String("id=e3334455-1aed-4e71-ab43-6bccf12092ee"),
})
if err != nil {
log.Fatal(err)
}
if res.AccountBalances != nil {
// handle response
}
}
