Python client for Digikey API

Project description

Python Client for Digikey API

Search for parts in the Digi-Key catalog by keyword using KeywordSearch. Then make a PartDetails call to retrieve all real time information about the part including pricing. PartDetails works best with Digi-Key part numbers as some manufacturers overlap other manufacturer part numbers.

What does it do

digikey-api is an Digkey Part Search API client for Python 3.6+. API response data is returned as Python objects that attempt to make it easy to get the data you want. Not all endpoints have been implemented.

Quickstart

Install

pip install digikey-api

export DIGIKEY_CLIENT_ID="client_id"
export DIGIKEY_CLIENT_SECRET="client_secret"
export DIGIKEY_STORAGE_PATH="cache_dir"

API V3

Register

Register an app on the Digikey API portal: Digi-Key API V3. You will need the client ID and the client secret to use the API. You will also need a Digi-Key account to authenticate, using the Oauth2 process.

When registering an app the OAuth Callback needs to be set to https://localhost:8139/digikey_callback.

Use [API V3]

Python will automatically spawn a browser to allow you to authenticate using the Oauth2 process. After obtaining a token the library will cache the access token and use the refresh token to automatically refresh your credentials.

You can test your application using the sandbox API, the data returned from a Sandbox API may not be complete, but the structure of the Sandbox API response will be a representation of what to expect in Production.

For valid responses make sure you use the client ID and secret for a Production App

import os
import digikey
from digikey.v3.productinformation import KeywordSearchRequest

os.environ['DIGIKEY_CLIENT_ID'] = 'client_id'
os.environ['DIGIKEY_CLIENT_SECRET'] = 'client_secret'
os.environ['DIGIKEY_CLIENT_SANDBOX'] = 'False'
os.environ['DIGIKEY_STORAGE_PATH'] = 'cache_dir'

# Query product number
dkpn = '296-6501-1-ND'
part = digikey.product_details(dkpn)

# Search for parts 
search_request = KeywordSearchRequest(keywords='CRCW080510K0FKEA', record_count=10)
result = digikey.keyword_search(body=search_request)

Logging [API V3]

Logging is not forced upon the user but can be enabled according to convention:

import logging

logger = logging.getLogger(__name__)
logger.setLevel(logging.DEBUG)

digikey_logger = logging.getLogger('digikey')
digikey_logger.setLevel(logging.DEBUG)

handler = logging.StreamHandler()
handler.setLevel(logging.DEBUG)
logger.addHandler(handler)
digikey_logger.addHandler(handler)

Top-level APIs

Product Information

All functions from the PartSearch API have been implemented.

  • digikey.keyword_search()
  • digikey.product_details()
  • digikey.digi_reel_pricing()
  • digikey.suggested_parts()
  • digikey.manufacturer_product_details()

Batch Product Details

The one function from the BatchProductDetailsAPI API has been implemented.

  • digikey.batch_product_details()

Order Support

All functions from the OrderDetails API have been implemented.

  • digikey.salesorder_history()
  • digikey.status_salesorder_id()

TODO

API Limits

The API has a limited amount of requests you can make per time interval Digikey Rate Limits.

It is possible to retrieve the number of max requests and current requests by passing an optional api_limits kwarg to an API function:

api_limit = {}
search_request = KeywordSearchRequest(keywords='CRCW080510K0FKEA', record_count=10)
result = digikey.keyword_search(body=search_request, api_limits=api_limit)

The dict will be filled with the information returned from the API:

{ 
    'api_requests_limit': 1000, 
    'api_requests_remaining': 139
}

Sometimes the API does not return any rate limit data, the values will then be set to None.

API V2 [Deprecated]

NOTE: API V2 is not supported anymore by Digi-Key and you cannot register new applications

See API V3 above to use the new API.

Register

Register an app on the Digikey API portal: Digi-Key API V2. You will need the client ID and the client secret to use the API. You will also need a Digi-Key account to authenticate, using the Oauth2 process.

Use

Python will automatically spawn a browser to allow you to authenticate using the Oauth2 process. After obtaining a token the library will cache the access token and use the refresh token to automatically refresh your credentials.

import os
import digikey

os.environ['DIGIKEY_CLIENT_ID'] = 'client_id'
os.environ['DIGIKEY_CLIENT_SECRET'] = 'client_secret'
os.environ['DIGIKEY_STORAGE_PATH'] = 'cache_dir'

dkpn = '296-6501-1-ND'
part = digikey.part(dkpn)
print(part)
# <Part mpn=NE555DR>

print(part.manufacturer)
# 'Texas Instruments'

Test

python -m pytest --cov=digikey --doctest-modules --ignore=setup.py
python -m mypy digikey --ignore-missing-imports
