# Getting Started

## Installing a Library

Client need to install this library to install the library by issuing the command from python console
```
python3 -m pip install gfdlws
```
or on windows command prompt
```
pip install gfdlws
```
---

## How to Connect using WebSocket API

Once installation is completed client can connect to API server by the code sample given below:
<br><br>**Syntax:**<br>
```
import gfdlws as gw
import sys

con = gw.ws.connect(<EndPoint>, <API Key>)
```
Here in above code sample:

- Endpoint : endpoint is URL like 'ws://endpoint:port'. End point URL and Port number will be provided by Global Datafeeds.

- API Key : This is the key which will be authenticated and once key was authenticated, client can request data by using function given in the above list.

<br>**Response**<br>
If key is authenticated server will send below response in JOSN format
```
{"Complete":true,"Message":"Welcome!","MessageType":"AuthenticateResult"}"
```
---

# Realtime data requests

Client can get real-time data through API. This data will be of two types:

1. Client can subscribe Realtime data and get the data for every second.

2. Client can subscribe Realtime snapshots data, returns data snapshot as per Periodicity & Period values.
---
## SubscribeRealtime
In this client will receive the data with 1 second frequency. This data will start once request is sent and will continue till market is open. Below is the sample code to get this data:
<br><br>**Syntax:**<br>
```
import gfdlws as gw
import sys

con = gw.ws.connect(<EndPoint>, <API Key>)
while True:
	time.sleep(1)
	response = gw.realtime.get(con,<Exchange>,<InstrumentIdentifier>, <Unsubscribe Optional [true]/[false][default=false]>)
	print(str(response))
```
<br>**Example**<br>
```
import gfdlws as gw
import sys

con = gw.ws.connect(<EndPoint>, <API Key>)
while True:
    time.sleep(1)
    response = gw.realtime.get(con, 'NFO', 'NIFTY-I')
    print(str(response))
```
<br>Client will get data for 'SBIN' in response for each second. Sample response is given below. This response will be in JSON format.
<br>**Response**<br>

```
{"Exchange":"NFO","InstrumentIdentifier":"NIFTY-I","LastTradeTime":1669262572,"ServerTime":1669262572,"AverageTradedPrice":18309.69,"BuyPrice":18323.9,"BuyQty":50,"Close":18286.75,"High":18329.35,"Low":18297.15,"LastTradePrice":18325.0,"LastTradeQty":750,"Open":18310.0,"OpenInterest":5657350,"QuotationLot":50.0,"SellPrice":18325.1,"SellQty":100,"TotalQtyTraded":681250,"Value":12473476312.5,"PreOpen":false,"PriceChange":38.25,"PriceChangePercentage":0.21,"OpenInterestChange":-98200,"MessageType":"RealtimeResult"}
```
---
## SubscribeSnapshot:
In this client will receive real-time Snapshots data, this function returns snapshot data as per Periodicity & Period values provided. This snapshot data will start once request is sent and will continue till market is open. Below is the sample code to get snapshot data:
<br><br>**Syntax:**<br>
```	
import gfdlws as gw
import sys

con = gw.ws.connect(<EndPoint>, <API Key>)
while True:
    time.sleep(1)
	response = gw.realsnapshot.get(con,<Exchange>,<InstrumentIdentifier>,<Periodicity>,<Period>,<Unsubscribe Optional[true]/[false][default=false]>)
	print(str(response))
```	
<br>**Example**<br>
```	
import gfdlws as gw
import sys
con = gw.ws.connect(<EndPoint>, <API Key>)
while True:
    time.sleep(1)
    response = gw.realsnapshot.get(con, 'NFO', 'NIFTY-I','MINUTE','1')
    print(str(response))
```
Client will get data for 'NIFTY' current contact in response for each minute when minute id finished. 'NIFTY-I' is InstrumentIdentifier (Symbol) to understand more about the 'Symbol Naming Conventions' check [here.](https://globaldatafeeds.in/global-datafeeds-apis/global-datafeeds-apis/documentation-support/symbol-naming-conventions/)
<br>Sample response is given below. This response will be in JSON format.
<br>**Response**<br>

```

This API will provide on demand real time and historical data in JSON format from server. It is Suitable for Web, Mobile as well as Desktop Applications. Below are the list of function and their respective details available in WebSocket API. For more detail Documentation & Support refer to the page by **Global Datafeeds** [here.](https://globaldatafeeds.in/global-datafeeds-apis/documentation-support/documentation/websockets-api-documentation/) <br>\r\n\r\nThis python library is developed to save time and efforts of clients while working on implementation of WebSocket API of Global Datafeeds.

Parameters\r\n\r\n---\r\n\r\n# Getting Started\r\n\r\n## Installing a Library\r\n\r\nClient need to install this library to install the library by issuing the command from python console\r\n```\r\npython3 -m pip install gfdlws\r\n```\r\nor on windows command prompt\r\n```\r\npip install gfdlws\r\n```\r\n---\r\n\r\n## How to Connect using WebSocket API\r\n\r\nOnce installation is completed client can connect to API server by the code sample given below:\r\n<br><br>**Syntax:**<br>\r\n```\r\nimport gfdlws as gw\r\nimport sys\r\n\r\ncon = gw.ws.connect(<EndPoint>, <API Key>)\r\n```\r\nHere in above code sample:\r\n\r\n- Endpoint : endpoint is URL like 'ws://endpoint:port'. End point URL and Port number will be provided by Global Datafeeds.\r\n\r\n- API Key : This is the key which will be authenticated and once key was authenticated, client can request data by using function given in the above list.\r\n\r\n<br>**Response**<br>\r\nIf key is authenticated server will send below response in JOSN format\r\n```\r\n{\"Complete\":true,\"Message\":\"Welcome!\",\"MessageType\":\"AuthenticateResult\"}\"\r\n```\r\n---\r\n\r\n# Realtime data requests\r\n\r\nClient can get real-time data through API. This data will be of two types:\r\n\r\n1. Client can subscribe Realtime data and get the data for every second.\r\n\r\n2. Client can subscribe Realtime snapshots data, returns data snapshot as per Periodicity & Period values.\r\n---\r\n## SubscribeRealtime\r\nIn this client will receive the data with 1 second frequency. This data will start once request is sent and will continue till market is open. Below is the sample code to get this data:\r\n<br><br>**Syntax:**<br>\r\n```\r\nimport gfdlws as gw\r\nimport sys\r\n\r\ncon = gw.ws.connect(<EndPoint>, <API Key>)\r\nwhile True:\r\n\ttime.sleep(1)\r\n\tresponse = gw.realtime.get(con,<Exchange>,<InstrumentIdentifier>, <Unsubscribe Optional [true]/[false][default=false]>)\r\n\tprint(str(response))\r\n```\r\n<br>**Example**<br>\r\n```\r\nimport gfdlws as gw\r\nimport sys\r\n\r\ncon = gw.ws.connect(<EndPoint>, <API Key>)\r\nwhile True:\r\n    time.sleep(1)\r\n    response = gw.realtime.get(con, 'NFO', 'NIFTY-I')\r\n    print(str(response))\r\n```\r\n<br>Client will get data for 'SBIN' in response for each second.
