gr4vy 0.15.0

Python SDK for Gr4vy

Gr4vy SDK for Python

Gr4vy provides any of your payment integrations through one unified API. For more details, visit gr4vy.com.

Installation

To add Gr4vy to your project simply install with pip:

pip install gr4vy

Add import:

import gr4vy

Getting Started

To make your first API call, you will need to request a Gr4vy instance to be set up. Please contact our sales team for a demo.

Once you have been set up with a Gr4vy account you will need to head over to the Integrations panel and generate a private key. We recommend storing this key in a secure location but in this code sample, we simply read the file from disk. For multi-merchant environments, an optional merchant ID can be provided as well.

from gr4vy import Gr4vyClient
client = Gr4vyClient("gr4vy_instance","location_of_key_file", "sandbox_or_production", "my-merchant-id)
client.ListBuyers()

Gr4vy Embed

To create a token for Gr4vy Embed, call the client.GetEmbedToken(embed) function with the amount, currency, and optional buyer information for Gr4vy Embed.

embed = {
  "amount": 1299,
  "currency": "USD",
  "buyerExternalIdentifier": "user-12345",
}

token = client.generate_embed_token(embed)

You can now pass this token to your frontend where it can be used to authenticate Gr4vy Embed.

The buyer_id and/or buyer_external_identifier fields can be used to allow the token to pull in previously stored payment methods for a user. A buyer needs to be created before it can be used in this way.

  from gr4vy import Gr4vyClient

  client = Gr4vyClient("gr4vy_instance","private_key.pem", "production")

  buyer_request = {"display_name": "Jane Smith"}

  new_buyer = client.create_new_buyer(**buyer_request).get('id')
  embed_data = {
    "amount": 1299,
    "currency": "USD",
    "buyerId": new_buyer,
  }

  embed_token = client.generate_embed_token(embed_data=embed_data)

  print("Embed token: {}".format(embed_token))

Checkout sessions can also be passed within an Embed token:

  from gr4vy import Gr4vyClient

  client = Gr4vyClient("gr4vy_instance","private_key.pem", "production")

  checkout_session_id = client.create_new_checkout_session().get("id")
  
  embed_data = {
    "amount": 1299,
    "currency": "USD",
  }

  emebed_token = client.generate_embed_token(
        embed_data=embed_data, checkout_session_id=checkout_session_id
    )

  print("Embed token: {}".format(embed_token))

Initialization

The client can be initialized with the Gr4vy ID (gr4vyId), the location of the private key, and the environment attempting to access.

  client = Gr4vyClient("gr4vyId","private_key.pem", "sandbox")

Alternatively, instead of the gr4vyId it can be initialized with the baseUrl of the server to use directly and the environment attempting to access.

  client = Gr4vyClientWithBaseUrl("https://*gr4vyId*.gr4vy.app","private_key.pem", "sandbox")

Your API private key can be created in your admin panel on the Integrations tab.

Multi Merchant

Setting the Merchant ID for requests can be set on the client:

  client = Gr4vyClient("gr4vyId","private_key.pem", "sandbox", merchant_account_id="merchant-id")

Making API calls

This library conveniently maps every API path to a separate function. For example, GET /buyers?limit=100 would be:

  client.list_buyers({"limit=100"})

To create, the API requires a request object for that resource. This is created by creating a dictionary object for the request.

For example, to create a buyer:

  from gr4vy import BuyerRequest

  buyer_request = {"display_name": "Jane Smith"}
  new_buyer = client.add_buyer(**buyer_request)

To update a buyer:

  buyer_id: "buyer_uuid_from_gr4vy"
  buyer_request = {"display_name": "Jane Changed")
  buyer_update = client.update_buyer(buyer_id, **buyer_request)

Response

Every resolved API call returns the requested resource, errors are printed to the console

  print(client.list_buyers())

Logging & Debugging

The SDK makes it possible to log responses to the console.

  print(client.list_buyers())

This will output the request parameters and response to the console as follows.

{"items":[{"id":"b8433347-a16f-46b5-958f-d681876546a6","type":"buyer","display_name":"Jane Smith","external_identifier":None,"created_at":"2021-04-22T06:51:16.910297+00:00","updated_at":"2021-04-22T07:18:49.816242+00:00"}],"limit":1,"next_cursor":"fAA0YjY5NmU2My00NzY5LTQ2OGMtOTEyNC0xODVjMDdjZTY5MzEAMjAyMS0wNC0yMlQwNjozNTowNy4yNTMxMDY","previous_cursor":None}
