This SDK might be also compatible, however not actively tested, with JavaScript "edge" runtimes that do not support all Node APIs, for example, Vercel Edge Runtime, or Cloudflare Workers.
To make it work, replace the SDK's built-in fetch function (which relies on Node APIs) with the runtime's native fetch function. Pass the function into the constructor with proper binding:
const client = new FingerprintJsServerApiClient({
region: Region.EU,
apiKey: apiKey,
fetch: fetch.bind(globalThis),
});
FingerprintJsServerApiClient({region: Region, apiKey: string}) constructorCreates an instance of the client.
const client = new FingerprintJsServerApiClient({region: Region.EU, apiKey: "<api_key>"});
region: Region - a region of the server, possible values: Region.EU, Region.AP, or Region.GlobalapiKey: string - secret API key from the FingerprintJS dashboardfetch?: typeof fetch - optional implementation of fetch function (defaults to node-fetch)client.getVisitorHistory(visitorId: string, filter?: VisitorHistoryFilter): Promise<VisitorsResponse>Gets history for the given visitor and given filter, returns a promise with visitor history response.
client.getVisitorHistory("<visitorId>", filter)
.then(visitorHistory => {
console.log(visitorHistory);
})
.catch(error => {
if (error.status === 403) {
console.log(error.error);
} else if (error.status === 429) {
retryLater(error.retryAfter); // this function needs to be implemented on your side
}
});
visitorId: string - identifier of the visitorfilter?: VisitorHistoryFilter - visitor history filter, more info in the API documentationPromise<VisitorsResponse> - promise with visitor history responseVisitorHistoryFilterFilter for querying API - see query parameters.
const filter = {
request_id: "<request_id>",
linked_id: "<linked_id>",
limit: 5,
paginationKey: "<paginationKey>"
};
request_id: string - filter visits by requestId.
Every identification request has a unique identifier associated with it called requestId. This identifier is returned to the client in the identification result. When you filter visits by requestId, only one visit will be returned.
linked_id: string - filter visits by your custom identifier.
You can use linkedId to associate identification requests with your own identifier, for example: session ID, purchase ID, or transaction ID. You can then use this linked_id parameter to retrieve all events associated with your custom identifier.
limit: number - limit scanned results.
For performance reasons, the API first scans some number of events before filtering them. Use limit to specify how many events are scanned before they are filtered by requestId or linkedId. Results are always returned sorted by the timestamp (most recent first). By default, the most recent 100 visits are scanned, the maximum is 500.
paginationKey: string - use paginationKey to get the next page of results.
When more results are available (e.g., you requested 200 results using limit parameter, but a total of 600 results are available), the paginationKey top-level attribute is added to the response. The key corresponds to the requestId of the last returned event. In the following request, use that value in the paginationKey parameter to get the next page of results:
GET api-base-url/visitors/:visitorId?limit=200response.paginationKey to get the next page of results: GET api-base-url/visitors/:visitorId?limit=200&paginationKey=1683900801733.Ogvu1jPagination happens during scanning and before filtering, so you can get less visits than the limit you specified with more available on the next page. When there are no more results available for scanning, the paginationKey attribute is not returned.

getEvent and getVisitorHistory methods return generic types Promise<EventResponse> and Promise<VisitorsResponse> and throw EventError and VisitorsError.
You can use typeguards to narrow error types as in example below.
import { isVisitorsError, isEventError } from '@fingerprintjs/fingerprintjs-pro-server-api';
client
.getVisitorHistory("<visitorId>", filter)
.then(result => console.log(result))
.catch(err => {
if (isVisitorsError(err)) {
if (err.code === 429) {
// VisitorsError429 type
retryLater(err.retryAfter); // this function needs to be implemented on your side
} else {
console.log('error: ', err.error)
}
} else {
console.log('unknown error: ', err)
}
});
client
.getEvent("<requestId>")
.then(result => console.log(result))
.catch(err => {
if (isEventError(err)) {
console.log(`error ${err.code}: `, err.error.message)
} else {
console.log('unknown error: ', err)
}
});
