    Gr4vy Embed for React

    NPM Version License

    Quickly embed Gr4vy in your React app to store card details, authorize payments, and capture a transaction.

    Use @gr4vy/embed in a non-React application.

    Usage

    Via the command line, install this package as follows.

    npm install @gr4vy/embed-react --save-prod
    # yarn add @gr4vy/embed-react --save

    Get started

    To use Gr4vy Embed, import the Gr4vyEmbed component.

    const Gr4vyEmbed = require(`@gr4vy/embed-react`)
    // import Gr4vyEmbed from (`@gr4vy/embed-react)
    
    <Gr4vyEmbed
      gr4vyId='[GR4VY_ID]'
      token='[TOKEN]'
      amount={1299}
      currency='USD'
      country='US'
      form='#payment-form'
    />

    Note: Replace [GR4VY_ID] and [TOKEN] with the ID of your instance and JWT access token. See any of our server-side SDKs for more details.

    Form

    Gr4vy Embed expects the query for a HTML form to attach itself to. The values for this element is a query string that can be parsed by document.querySelector. For example <form id="cardform"> would be represented by #cardform.

    HTML Element Example Description
    form #order Specifies the HTML <form> element or a query for the element to attach additional inputs to. Gr4vy will automatically insert a hidden Input field into this form containing the transaction ID.

    Options

    The options for this integration are as follows.

    Field Default Description
    amount null The amount to authorize or capture in the specified currency. only.
    apiHost null Sometimes required - The host (both hostname and port) of the Gr4vy API server to use. Can be omitted when using the gr4vyId option.
    buyerExternalIdentifier null An optional external ID for a Gr4vy buyer. The transaction will automatically be associated to a buyer with that external ID. If no buyer with this external ID exists then it will be ignored. This option is ignored if the buyerId is provided.
    buyerId null An optional ID for a Gr4vy buyer. The transaction will automatically be associated to a buyer with that ID. If no buyer with this ID exists then it will be ignored.
    country null Required A valid ISO 3166 country code.
    currency null Required A valid, active, 3-character ISO 4217 currency code to authorize or capture the amount for.
    externalIdentifier null An optional external identifier that can be supplied. This will automatically be associated to any resource created by Gr4vy and can subsequently be used to find a resource by that ID
    gr4vyId null Often required Gr4vy ID automatically sets the apiHost to api.<gr4vyId>.gr4vy.app and iframeHost to embed.<gr4vyId>.gr4vy.app.
    iframeHost null Sometimes required - The host (both hostname and port) of the server that hosts the Gr4vy payment form. Can be omitted when using the gr4vyId option.
    intent authorize authorize, capture - Defines the intent of this API call. This determines the desired initial state of the transaction.
    locale en An optional locale, this consists of a ISO 639 Language Code followed by an optional ISO 3166 Country Code, e.g. en, en-gb or pt-br.
    onEvent null An optional event handler to bind to the form. This is called for various events, more on that below.
    store ask 'ask', true, false - Explicitly store the payment method or ask the buyer, this is used when a buyerId or buyerExternalIdentifier is provided.
    theme null Theme customisation options (See Theming)
    token null Required - The server-side generated JWT token used to authenticate any of the API calls.
    onComplete null Callback with a transaction object. (Form submission must be handled manually)
    display all all, addOnly, storedOnly, supportsTokenization - Filters the payment methods to show stored methods only, new payment methods only or methods that support tokenization.
    customOptions null List of custom options. e.g. [{ label: 'Giftcard', method: 'giftcard', description: 'You will be asked for a giftcard code.', iconUrl: 'data:image/svg+xml,...'}]
    onCustomSubmit null Callback when a custom payment option is selected and the form submitted.
    metadata Object An optional object of key/values for transaction metadata. All values should be a string.
    paymentSource null installment, moto, recurring - Can be used to signal that Embed is used to capture the first transaction for a subscription or an installment. When used, store is implied to be true and display is implied to be supportsTokenization. This means that payment options that do not support tokenization are automatically hidden.
    cartItems Array An optional array of cart item objects, each object must define a name, quantity, and unitAmount.
    statementDescriptor Object An optional object with information about the purchase to construct the statement information the buyer will see in their bank statement. Please note support for these fields varies across payment service providers and underlying banks, so Gr4vy can only ensure a best effort approach for each supported platform.
    As an example, most platforms will only support a concatenation of name and description fields, truncated to a length of 22 characters.
    The object can contain name, description, phoneNumber, city and url keys, with string values. phoneNumber should be in E164 format. Gr4vy recommends avoiding characters outside the alphanumeric range and the dot (.) to ensure wide compatibility.
    secure true An optional boolean which forces iframeHost and apiHost to use https protocol by default. This is useful for local development using http protocol.
    requireSecurityCode false An optional boolean which forces security code to be prompted for stored card payments.

    Events

    The onEvent option can be used to listen to certain events emitted from the form.

    <Gr4vyEmbed
      amount={1299}
      currency='USD'
      onEvent={(name, data) => {...}}
      ...
    />
    })

    Currently, we Gr4vy Embed emits the following events.

    agumentError

    Returned when the initial input (element, options) are incorrectly formatted or missing.

    {
      "code": "argumentError",
      "option": "currency",
      "message": "must be a valid number"
    }

    optionsLoaded

    Returned when options are loaded. Stored options include the id.

    [
      {
        "id": "...",
        "method": "card",
        "mode": "card"
      },
      {
        "method": "card",
        "mode": "card"
      }
    ]

    formUpdate

    Returned when the form updates. Currently this only informs the developer if the form is valid.

    {
      "valid": false
    }

    transactionCreated

    Returns a full transaction object when Gr4vy accepted the transaction, regardless of its status. Be aware that this can be a pending or declined transaction. To track API failures please use the transactionFailed event.

    {
      "type": "transaction",
      "id": "8724fd24-5489-4a5d-90fd-0604df7d3b83",
      "status": "pending",
      ...
    }

    transactionCancelled

    Returned when a buyer has explicitly cancelled a transaction, e.g. closing a popup or dismissing Apple Pay. This is currently not supported for 3-D Secure transactions and should not be conflated with transaction being declined or an error occuring.

    {
      "type": "transactionCancelled"
    }

    transactionFailed

    Returned when an API call fails to create a transaction due to a client or server error. In other words, this event is raised when incorrect data (like an invalid JWT) is passed to the Gr4vy API and a HTTP status code in the 4XX or 5XX range is returned.

    To catch failed or declined transactions due to downstream issues with the payment service, please subscribe to the transactionCreated event.

    {
      "type": "error",
      "code": "unauthorized",
      "status": 401,
      "message": "No valid API authentication found"
    }

    apiError

    Returned when the form encounters an API error.

    {
      "type": "error",
      "code": "unauthorized",
      "status": 401,
      "message": "No valid API authentication found",
      "details": []
    }

    Custom Form Submission

    Embed will automatically submit the payment form with hidden inputs, this can be prevented using the onComplete callback.

    <Gr4vyEmbed
      amount={1299}
      currency='USD'
      onEvent={(name, data) => {...}}
      onComplete={(transaction) => {
        // Handle custom form submission
      }}
    />

    Submission without a Form

    Embed does not require a form to be present, in order to access the EmbedInstance directly you can pass a ref. You should implement onComplete if you are choosing this option.

    import Gr4vyEmbed, { EmbedInstance } from '@gr4vy/embed-react';
    import { useRef } from 'react';
    
    const MyComponent = () => {
      const embed = useRef<EmbedInstance>();
    
      return <div>
        <Gr4vyEmbed ref={embed} {...}/>
        <button onClick={() => embed.current.submit()}>
      </div>
    
    }

    Custom Options

    Embed will render custom payment options if you need to integrate with existing checkouts. This will not trigger any processing by embed and instead you will need to handle the form submission. You should implement onComplete if you are choosing this option.

    <Gr4vyEmbed
      // Provide a list of custom options
      customOptions={[
        {
          label: 'Giftcard',
          method: 'giftcard', // This should be a unique identifier for your custom option
          description: 'You will be asked to enter a giftcard',
          iconUrl: `data:image/svg+xml,...`, // This should be a data:image/svg+xml url
        }
      ]}
      // Handle the submit for a custom option
      onCustomSubmit={({ method: 'giftcard' }) => {
        console.log(`Paid by ${method}`);
      }}
    />
