# Welcome to KlearStack's API Documentation In this documentation you can find the following, * Authentication * Supported API methods * Request types and URLs * Input parameters for each method * Responses for each method API Endpoints Security: All API endpoints are protected and require an access token for access. To obtain an access token, perform a POST request to get\_access\_token, which returns an access\_token and a refresh\_token. The access token is valid for a short duration (15 minutes) and expires after this period. The refresh token, however, is valid for at least a day. To obtain a new access token, perform a POST request to getaccesstokenfromrefreshtoken, which will return a new access token with a reset expiration time. POST Request Parameters: All API POST request parameters should be sent as "Form Data". Request Through Postman: To access a secured endpoint through Postman, copy and paste the access token into the Authorization tab of the request as a Bearer Token. Request in Python: Below is an example request format in Python:\ `token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ0b2tlbl90eXBlIjoiYW"` `token = "Bearer " + str(token) # mind the space` `headers = {"Authorization": token}` `requests.post(url, data=data, headers=headers)` #### **Please note that the SSL verification must be turned off. For example,** * In Python, disable SSL verification by passing the verify=False parameter. * In Postman, turn off SSL Certificate Verification.
