Getting Started


First start by adding ClaimR's React Native client as a dependency to your React Native project. If you're using NPM, then run:

npm install @claimr/react-native-client

If you're using Yarn, run:

yarn add @claimr/react-native-client

Create a ClaimrClient

Next, create a ClaimrClient instance. For this you need your own API key, which you can get at the ClaimR Dashboard.

import { ClaimrClient } from '@claimr/react-native-client'
const client = new ClaimrClient({ apiKey: 'YOUR_API_KEY' })

To circumvent hard-coding the API key, we recommend storing them outside your code-base, for example using react-native-config or other similar tools.

Verify Location Hook

The last step is to start using the useLazyVerifiedLocation hook. In the background this hook will collect GNSS data. Once enough data has been collected, the submit function will be populated, which when invoked will send recent GNSS data to the ClaimR API to verify the current location. After the location is verified, the results will be available in claim and also encoded as a JWT in jwt.

import { useLazyVerifiedLocation } from '@claimr/react-native-client'
const MyModule = () => {
const { claim, jwt, submit } = useLazyVerifiedLocation({ client })
return (
{submit && <Button onPress={submit} title={'Submit'} />}
{claim && (
{claim.location.latitude}, {claim.location.longitude}
{jwt && <Text>JWT: {jwt}</Text>}

For a more elaborate useage example, see our example React Native client here and explore the API.
