I'm trying to follow Plaid's documentation from here and I can't seem to figure out where do I get the public_token from when I'm working on Plaid development environment. They're saying that:
In their second example:
from plaid import Client
client = Client(client_id='***', secret='***', public_key='***', environment='sandbox')
# the public token is received from Plaid Link
response = client.Item.public_token.exchange(public_token)
access_token = response['access_token']
I don't know where the public_token comes from. If I go to that Plaid Link they say:
This repository is now deprecated. To integrate with Plaid, visit the docs. https://plaid.com/docs
Then, when I go to their official docs I can't seem to find any way of getting that public token.
I'm trying to do something along these lines:
from exceptions import (
InvalidPlaidEnvironment,
MissingPlaidCredential
)
from plaid import Client
from plaid.errors import APIError, ItemError, InvalidRequestError
VALID_ENVIRONMENTS = (
'sandbox',
'development',
'production'
)
CLIENT_ID = '<development_client_id>'
SECRET = '<development_secret>'
PUBLIC_KEY = '<development_public_key>'
ENVIRONMENT = 'development'
class PlaidProcessor:
"""
Simple processor class for Plaid API
"""
def __init__(
self,
client_id=CLIENT_ID,
secret=SECRET,
public_key=PUBLIC_KEY,
environment=ENVIRONMENT
):
"""
Constructor for PlaidProcessor. Initialize our class with basic credentials
data.
Args:
client_id (str): Plaid client ID
secret (str): Plaid secret
public_key (str): Plaid public key
environment (str): One of sandbox, development, or production
"""
self.client_id = client_id
self.secret = secret
self.public_key = public_key
self.environment = environment
if not self.client_id:
raise MissingPlaidCredential(
'Missing CLIENT_ID. Please provide Plaid client id.'
)
if not self.secret:
raise MissingPlaidCredential(
'Missing SECRET. Please provide Plaid secret.'
)
if not self.public_key:
raise MissingPlaidCredential(
'Missing PUBLIC_KEY. Please provide Plaid public key.'
)
if not self.environment:
raise MissingPlaidCredential(
'Missing environment. Please provide Plaid environment.'
)
if self.environment.lower() not in VALID_ENVIRONMENTS:
valid_environments_str = ','.join(VALID_ENVIRONMENTS)
raise InvalidPlaidEnvironment(
f'Please insert one of the following environments: {valid_environments_str}'
)
self.client = Client(
client_id=self.client_id,
secret=self.secret,
public_key=self.public_key,
environment=self.environment
)
self.access_token = None
self.public_token = None
def get_public_token(self):
# how do I get the access token?
pass
In the docs, they're also specifying the following:
A
public_token(which is returned in your LinkonSuccess()callback) should be passed to your server, which will exchange it for anaccess_token. public_tokens are one-time use tokens and expire after 30 minutes. You can generate new public_tokens as needed via the /item/public_token/create endpoint.An
access_tokenis used to access product data for an Item. This should be stored securely, and never in client-side code. This is used to make authenticated requests to the Plaid API for the user. By default, access_tokens do not expire, though you can rotate them; if it winds up in an error state, the access_token will work again if the Item’s error is resolved. Each access_token is unique to a specific Item, and cannot be used to access other Items.
but this is just more confusing. Can anybody give me some advice regarding this?
