@mifiel/api-client

Library to wrap the most common methods of Mifiel API.

This library depends on @mifiel/api-client-auth to authenticate the Mifiel API calls.

Installation

npm install @mifiel/api-client-auth @mifiel/api-client --save
# or
yarn add @mifiel/api-client-auth @mifiel/api-client

Usage

// for ESM or TypeScript
import { Config } from '@mifiel/api-client-auth';
// for CJS
const { Config } = require('@mifiel/api-client-auth');

Config.setTokens({
  appId: '<APP_ID>',
  appSecret: '<APP_SECRET>',
  // [optional] - by default is production
  env: 'production' | 'sandbox' 
});

All methods return promises

Model Crud

We provide you a Model class to wrap API CRUD operations. You should create an instance sending the resource name.

import { Model } from '@mifiel/api-client';

const documentModel = new Model('documents');

// GET /documents
const documents = await documentModel.all();
// GET /documents/document-id
const doc = await documentModel.find('document-id');
// POST /documents
await documentModel.create({ ...docAttributes });
// DELETE /documents/document-id
await documentModel.delete('document-id');
// PATCH /documents/document-id
await documentModel.update('document-id', { ...docAttributes });

Document methods

import { Document } from '@mifiel/api-client';

The Document is an instance from a extended class of Model, so it inherits the CRUD operations (find, all, delete, create and update).

Document.getHash

Return the hex hash of a file.

import { Document } from '@mifiel/api-client';
import path from 'path';
import fs from 'fs';

const filepath = path.join(__dirname, 'my-file.pdf');
const fileBuffer = fs.readFileSync(filepath);

const hexHash = await Document.getHash(fileBuffer);

Document.getFile

Return the document related file.

import { Document } from '@mifiel/api-client';

// original file of document-id
const file = await Document.getFile({ documentId: 'document-id', type: 'file' });
// signed file (original file + signature page) of document-id
const fileSigned = await Document.getFile({ documentId: 'document-id', type: 'file_signed' });
// signed xml file
const fileSigned = await Document.getFile({ documentId: 'document-id', type: 'xml' });

Document.saveFile

Save Document related files.

import { Document } from '@mifiel/api-client';

await Document.saveFile({
  documentId: 'document-id',
  type: 'file' | 'file_signed' | 'xml',
  path: 'path/to/save/my-file.pdf'
});

Document.create

Use only original_hash if you don't want us to have the file. Either file or original_hash must be provided.

import { Document } from '@mifiel/api-client';
import path from 'path';
import fs from 'fs';

const filepath = path.join(__dirname, 'you-file.pdf');
const fileBuffer = fs.readFileSync(filepath);

// sending file to Mifiel server
const newDocumentWithFile = await Document.create({
  file: filepath,
  signatories: [{
    name: 'Signer 1',
    email: '[email protected]',
    tax_id: 'AAA010101AAA'
  }, {
    name: 'Signer 2',
    email: '[email protected]',
    tax_id: 'AAA010102AAA'
  }],
  // ...
});

// sending only the hash of file
const hexHash = await Document.getHash(fileBuffer);
const newDocumentOnlyHash = await Document.create({
  original_hash: hexHash,
  name: 'my-file.pdf',
  signatories: [
    //...
  ],
  // ...
});

Document.transfer

Use this method to transfer an endorsable document.

import { Document } from '@mifiel/api-client';

const doc = await Document.transfer({
  documentId: 'document-id-to-transfer',
  receiver: {
    email: '[email protected]',
    tax_id: 'ZAAE9306278TA',
  },
  signatories: [{
    name: 'Signer',
    email: '[email protected]',
    tax_id: 'AAA010102AAA',
    type: 'beneficiary',
  }]
})

Certifcate methods

import { Certificate } from '@mifiel/api-client';

The Certificate is an instance from a extended class of Model, so it inherits the CRUD operations (find, all, delete, create and update).

Certificate.create

import { Certificate } from '@mifiel/api-client';
import path from 'path';

const filepath = path.join(__dirname, 'you-cer.cer');

const newCertificate = await Certificate.create({ filepath });

User methods

import { User } from '@mifiel/api-client';

The User instance doesn't inherit from Model, so it doesn't have the CRUD operations.

User.me

Return the user data.

import { User } from '@mifiel/api-client';

const user = await User.me();

User.setupWidget

Every user (issuer or receiver) of an endorsable document must set up his account. During this setup process, we will use the user's FIEL/e.firma to derive a set of cryptocurrency addresses where the assets (the endorsable documents) will be stored.

Important: Save the widget_id in your database. If the user does not complete the setup, you should use the same widget_id when the user comes back to the setup flow.

import { User } from '@mifiel/api-client';

const user = await User.setupWidget({
  email: '[email protected]',
  tax_id: 'ZAAE9306278TA',
});

// save it in your database
user.widget_id

Template methods

import { Template } from '@mifiel/api-client';

The Template is an instance from a extended class of Model, so it inherits the CRUD operations (find, all, delete, create and update).

Templates are a tool that allows you to create templates that have a base format. You can define fields within the html so you can then create a custumized document.

Template.getFields

Get the fields of a specific template. Use it to know what to send to generate documents with this template.

import { Template } from '@mifiel/api-client';

const fields = await Template.getFields({ templateId: 'template-id' });

Template.getDocuments

Get all the active (non deleted) documents generated from a specific template.

import { Template } from '@mifiel/api-client';

const documents = await Template.getDocuments({ templateId: 'template-id' });

Template.generateDocument

Generate a document from a template.

import { Template } from '@mifiel/api-client';

const documents = await Template.generateDocument({
  templateId: 'template-id',
  document: {
    name: 'Mi Client Name',
    signatories: [{
      name: 'Signer 1',
      email: '[email protected]',
      tax_id: 'AAA010101AAA'
    }]
  }
});

Template.generateDocuments

The generation of documents runs in the background. We will respond with 200 (OK) and start generating the documents. When our servers finish, we will POST you to the provided callback_url with a list of the created documents.

import { Template } from '@mifiel/api-client';

const documents = await Template.generateDocuments({
  templateId: 'template-id',
  callback_url: 'https://www.my-site.com/webhook',
  documents: [{
    name: 'Mi Client Name',
    // ...
  }]
});
