##### API Overview - Accounts list and balance - Transaction overview (also for saving accounts) - Payments import - Statement list and download - FX rates ##### Authentication Before making a call to Premium API, you need to register your app at our _Developer portal_. This is where you get the **ClientID** that your application must send in the request as `X-IBM-Client-Id`. This is the key that grants your app access to the API. However, this may not be enough. Your application needs to use mTLS to call most operations here. Thus, you not only need _https_ but also a client certificate issued by us. The exception is two operations for FX rates that are accessible also without a client certificate. Each bank client/user can issue several certificates. Each certificate can permit different sets of operations (http methods) on different bank accounts. All this must be configured in Internet Banking first by each bank client/user (bank clients need to look under _Settings_ and do not forget to download the certificate at the last step). The certificate is downloaded in **PKCS#12** format as **\*.p12** file and protected by a password chosen by the bank client/user. Yes, your app needs the password as well to get use of the **\*p12** file for establishing mTLS connection to the bank. Client certificates issued in Internet Banking for bank clients/users have limited validity (e.g. **5 years**). However, **each year** certificates are automatically blocked and bank client/user must unblock them in Internet Banking. It is possible to do it in advance and prolong the time before the certificate is blocked. Your app should be prepared for these scenarios and it should communicate such cases to your user in advance to provide seamless service and high user-experience of your app. ##### Rate Limiting The number of requests in each API operation is limited to 10 per client per sliding second and 5000 per client per sliding day. The exception is the 'Download Statement' operation with the limits lowered to 5 per client per sliding second and 1500 per client per sliding day. This is because it transports potentially sizeable binary files. The consumer must be able to handle HTTP status 429 in case of exceeding these limits. Response headers `X-RateLimit-Limit-Second` and `X-RateLimit-Limit-Day` show the actual limits configured for the specific operation. Response headers `X-RateLimit-Remaining-Second` and `X-RateLimit-Remaining-Day` are returned to help prevent the limits from being exceeded. ##### Notes Be aware, that in certain error situations, API can return specific error structures along with 5xx status code, which is not explicitely defined below. ##### Quick Start Client Feel free to download a simple Java client that gives you quick access to our API.

Connect brokerage accounts to your app for live positions and trading. ## Rate limiting Two limits apply to requests signed with your `clientId`. The stricter one wins, and exceeding either returns `429 Too Many Requests`. - **Customer-level** — 250 requests/minute by default, scoped to your `clientId` and applied across all endpoints. Reported in `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset`. - **Account-level** — 10 requests/minute per account, scoped to (`clientId`, `accountId`). All covered operations for one account draw on the same bucket — reading balances and reading positions share it — and enforcement does not depend on the HTTP method, so updating an account consumes the same bucket as reading it. Only enforced for Personal users, and only for integrations it has been rolled out to — it is not yet in force for every Personal integration. It also does not apply on every operation that documents a 429 below. Where it applies it is reported in `X-RateLimit-Account-Limit`, `X-RateLimit-Account-Remaining` and `X-RateLimit-Account-Reset`. Do not read the absence of those headers as proof the limit is off — some configurations omit the rate limit headers while still enforcing the limit, so header absence tells you nothing about your allowance. On a 429, `X-RateLimit-Remaining: 0` means you hit the customer-level limit and `X-RateLimit-Account-Remaining: 0` means the account-level one. Wait for the corresponding `*-Reset` value (seconds) before retrying, or fall back to exponential backoff with jitter. Not every 429 is explained by those headers. A separate per-authenticated-user limit, reported in no `X-RateLimit-*` header, covers OAuth-authenticated requests and signed requests in configurations where the customer-level limit is not in effect — on the operations that use the default throttles. A few operations override those and are governed by the customer-level limit alone. The two do not stack: a signed request governed by the customer-level limit above is not additionally subject to the per-user one. If a 429 arrives with no header at zero — or with no `X-RateLimit-*` headers at all — honour `Retry-After` and back off. Treat the remaining counts as a hint, not a guarantee that the next request will succeed. Because the customer-level limit applies everywhere, any signed request can return 429. **OAuth-authenticated requests are an exception.** They are not subject to the customer-level limit and do not receive `X-RateLimit-Limit`, `X-RateLimit-Remaining` or `X-RateLimit-Reset` — do not wait on those headers or design around a customer-level allowance on this path. The account-level limit still applies to them on the account-data endpoints above, reported in the `X-RateLimit-Account-*` headers. On operations using the default throttles the per-user limit above applies to them as well, so an OAuth request can be rejected while the account headers still show capacity; on the few operations that override those throttles, OAuth callers have no per-user ceiling at all. Drive retries from `Retry-After` and exponential backoff with jitter rather than from the headers. See https://docs.snaptrade.com/docs/ratelimiting.
