FinP2P SDK Introduction

The Ownera sdk provides an easy to use set of APIs to work with Ownera FinP2P node for various use cases, the sdk handles most of the heavy lifting for executing operations on the FinP2P network, such as signature templates generation and signing, asset managements, escrow interface and more.

Ownera API service

The purpose of this sdk is to provide an interface to the Ownera APIs.
It covers the following:

• Transactional API
• Query API
• Escrow API
• Custody adapter
• Regulation verifiers

It exposes types for Typescript.

To build the lib/ and use the package, just run yarn build.

Usage

Core

SDK

import { Sdk } from "@owneraio/finp2p-sdk-js";

const sdk = new Sdk({
  orgId: "myOrdId",
  owneraAPIAddress: "https://my-ownera-node.io",
  owneraRASAddress: "https://my-ownera-reg-app-store.io",
  authConfig: { 
    apiKey: "<my-api-key>",
    secret: { 
      type: 1|2, 
      raw: "<my-stringified-private-key>",
    },
  },
  custodyAdapterBaseURL: "<optional-custody-url>",
});

Create asset

Returns Promise with AssetInterface

Usage example:

    const { email, name, phoneNumber } = payload.user;
    let issuer;

    const users = await sdk.owneraAPI.query.getUsers({});
    issuer = users.filter((o) => o.email === email)[0];

    if (!issuer) {
        const { id, publicKey } = await Custody.createAccount({
            name,
            phoneNumber,
        });
        
        const user = await sdk.createUser({
            withSignatureProvider: {
                publicKey,
                signingMethod: signingMethod({ id, custody: sdk.owneraAPI.custodyAdapter! }),
            },
        });

        issuer = await user.getData();
    }


  // Create Asset
    const createdAsset = await sdk.createAsset({
        name: "Asset Name",
        type: "company",
        verifiers: [
            {
                id: "1",
                name: "Accreditation",
                provider: "OTHER",
            },
        ],
        issuerId: issuer.id,
        denomination: {
            type: "fiat",
            code: "USD"
        }});
    
    // get asset data
    const createdAssetInfo = await createdAsset.getData();

Create user

Returns Promise with UserInterface

Usage example:

    // Create signing method using custody adapter
    const signingMethod = (custody: CustodyAdapter, id: string) => async (hash: string) => {
      let attempt = 0;
      let signatureResponse = await custody.createSignature({ id, hash });
      const signatureId = signatureResponse.id;
      const doRetry = !["FAILED", "COMPLETED"].includes(signatureResponse.status);
      while (doRetry && attempt < 10) {
        signatureResponse = await custody.getSignature({ signatureId });
        attempt = attempt + 1;
      }
    
      if (doRetry && attempt === 10) {
        throw {
          code: 408,
          name: "SignatureError",
          message: "Timeout - unable to get signature",
          data: signatureResponse,
        };
      }
    
      if (signatureResponse.status === "FAILED") {
        throw {
          code: 500,
          name: "SignatureError",
          message: "Failure - unable to get signature",
          data: signatureResponse,
        };
      }
    
      return Promise.resolve(signatureResponse.signature);
    };
    
    // Create user 
    const uniqueIdentifier = Date.now();
    const account = await sdk.owneraAPI.custodyAdapter!.createAccount({
      uniqueIdentifier,
      name: `${uniqueIdentifier} custody account`,
    });
    
    const user = await sdk.createUser({
      withSignatureProvider: {
        publicKey: account.publicKey,
        signingMethod: signingMethod(sdk.owneraAPI.custodyAdapter!, account.id),
      },
    });

Get Asset

Returns AssetInterface

Usage example:

    const assetInterface = await getAsset({ assetId });
    const asset = await assetInterface.getData();

Get User

Returns Promise with UserInterface

Usage example:

    const publicKey = "<your-public-key>";
    type signingMeth = (r: {custody: CustodyAdapter, id: string}): (hash: string, details?: SignatureDetails) => Promise<string>;
    const signingMethod: signingMeth = (r: {custody: CustodyAdapter, id: string}) => {/* Your signingMethod implementation */};

    const user = await getSdk().getUser({
        userId: r.userId,
        withSignatureProvider: {
            publicKey: userData.publicKey,
            signingMethod: signingMethod({
                custody: getSdk().owneraAPI.custodyAdapter!,
                id: investorCustodyAccountId,
            }),
        },
    });

user = await sdk.getUser({ userId: profile.id });

#### [Get Organization](./classes/sdk.md#getorganization)
Returns [OrganizationInterface](./interfaces/organizationinterface.md)

Usage example:
```typescript
    // get organization API
    const org = sdk.getOrganization({ });
