Identify Snap connects to your currently connected Metamask account by default. To learn how apps can connect to Identify Snap using a non-metamask(external) account, refer to this documentation.
Then, depending on whether you're trying to connect to a metamask account or a non-metamask account, you can call the snap API in the following way:
How the API is handled between the app and snap
What the API does
Retrieves the currently connected account and the blockchain network the user has selected on Metamask. If it's the first time, the account info is also saved in snap state.
Retrieves the VCs from google drive
Retrieves the VCs from the local Metamask snap state

Some things to keep in mind while interacting with the above demo
If you're getting any errors with the live demo, make sure you go through the section to learn about what you may be missing. You need to install in your browser for the live demo to work
To ease the integration of Identify Snap on an application, we have created a template web application that you can run locally and check out the code in its entirety to learn how you can integrate and interact with various APIs exposed by Identify Snap. Check out the full source code at .
You can also check out the to learn how each API works.
const snapId = `npm:@hashgraph/hedera-identify-snap`
const externalAccountParams = {
externalAccount: {
accountIdOrEvmAddress: '0.0.12345',
curve: 'ED25519'
}
}
const accessToken = 'ya29.a0Ael9sCPgMSbLRD5PIm5nyP............IXJ-OkUbbQ0166'
const params = {
accessToken
/*
Uncomment the below line if you want to connect to a non-metamask account
*/
// ...externalAccountParams
}
const handleSaveVCAPI = async () => {
await window.ethereum.request({
method: 'wallet_invokeSnap',
params: {
snapId,
request: {
method: 'configureGoogleAccount',
params: params
}
}
})
}
Compare the VCs from both stores and figure out what VCs are missing in snap state that are present in google drive and what VCs are missing in google drive that are present in snap state
Import the missing VCs from google drive onto Metamask snap state
Export the missing VCs from Metamask snap state onto google drive
Whenever there is a new version of the IdentifySnap, always make sure to first uninstall the old version of the snap from Metamask and only then try the above demo so it can install the latest version
