# Gr4vy SDK for Python

Gr4vy provides any of your payment integrations through one unified API. For
more details, visit [gr4vy.com](https://gr4vy.com).

## Installation

To add Gr4vy to your project simply install with pip:

```python
pip install gr4vy
```

Add import:

```python
import gr4vy
```

## Getting Started

To make your first API call, you will need to [request](https://gr4vy.com) 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.

```python
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.

```python
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.

```python
  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:

```python
  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",
  }

  embed_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.

```python
  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.

```python
  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:

```python
  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:

```python
  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:

```python
  from gr4vy import BuyerRequest

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

```

To update a buyer:

```python
  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


```python
  print(client.list_buyers())
```

## Webhooks verification

The SDK makes it easy to verify that incoming webhooks were actually sent by Gr4vy.
Once you have configured the webhook subscription with its corresponding secret, that
can be verified the following way:

```python
payload = request.data.decode("utf-8")
signature_header = request.headers.get("X-Gr4vy-Webhook-Signatures", None)
timestamp_header = request.headers.get("X-Gr4vy-Webhook-Timestamp", None)

try:
    client.verify_webhook(
        secret=WEBHOOK_SUBSCRIPTION_SECRET,
        payload=payload,
        signature_header=signature_header,
        timestamp_header=timestamp_header,
        timestamp_tolerance=0,  # optional
    )
except Gr4vySignatureVerificationError as exc:
    logger.error("Invalid signature!")
```

Bear in mind that extracting the payload and headers of the request depends on the used
framework. And that optionally you can validate the timestamp age with some tolerance.

## Logging & Debugging

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

```python
  print(client.list_buyers())
```

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

```sh
{"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}
```
