# resolveDID

## How to call the API from an app

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](/identify/identify-snap/snap-rpc-apis.md#connecting-to-a-non-metamask-external-account). 

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:

```tsx
const snapId = `npm:@hashgraph/hedera-identify-snap`

const externalAccountParams = {
  externalAccount: {
    accountIdOrEvmAddress: '0.0.12345',
    curve: 'ED25519'
  }
}
const params = {
  /* 
    Note that the 'did' parameter is optional. If did is not passed, 
    Identify Snap will assume that you want to resolve the DID of the currently
    connected account. This means this API can be used to resolve your own DID
    or another DID that does not belong to you.
  */
  // did: did,
  /* 
    Uncomment the below line if you want to connect to a non-metamask account
  */
  // ...externalAccountParams
}

const handleAccountInfoAPI = async () => {
  await window.ethereum.request({
    method: 'wallet_invokeSnap',
    params: {
      snapId,
      request: {
        method: 'resolveDID',
        params: params
      }
    }
  })
}
```

## How the API is handled between the app and snap

<figure><img src="/files/3JTrsl0d16fzg7E6nK5X" alt=""><figcaption></figcaption></figure>

## What the API does

1. 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.
2. Returns the DID document based on the did method that's currently selected.&#x20;

For an evm account `0x30F08B41491E9620d9Ba0f8F8a09a807752bBF3A`:

<summary>Some things to keep in mind while interacting with the above demo</summary>

* If you're getting any errors with the live demo, make sure you go through the [FAQs](/identify/basics/faqs.md) section to learn about what you may be missing. You need to install [Metamask](https://metamask.io/) in your browser for the live demo to work
* 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

{% hint style="info" %}
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 [template application github repository](https://github.com/tuum-tech/identify/tree/main/packages/site).

You can also check out the [API reference](/identify/identify-snap/snap-rpc-apis.md) to learn how each API works.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tuum.tech/identify/identify-snap/snap-rpc-apis/did-apis/resolvedid.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
