See below steps to obtain these.For app id. Login toAzure Portal, navigation to Azure AD B2C, Click on the Applications section and your app id should be listed.For Issuer and JWKS URI:Under the "User Flows", note down the name of yours, this will be needed shortly.Next, under Azure AD B2C, within the Applications section.Click on "Endpoints".Copy the endpoint with the label "OpenID Connect configuration endpoint (v2)"It will look something like:https://exampletenant.b2clogin.com/exampletenant.onmicrosoft.com/<policy-name>/v2.0/.well-known/openid-configurationNow replace<policy-name>with the name of your User Flow from earlierhttps://exampletenant.b2clogin.com/exampletenant.onmicrosoft.com/B2C_1_app_sign_in/v2.0/.well-known/openid-configurationNow visit that URL in your web browser.You should get a JSON response, note down the values for the keys 'issuer' and 'jwks_uri'.Now you have those values you can proceed to verify a Azure generated JWT Token.fromazure_ad_verify_tokenimportverify_jwtazure_ad_app_id='b74cd13f-8f79-4c98-b748-7789ecb1111d5'azure_ad_issuer='https://exampletenant.b2clogin.com/0867afa-24e7-40e9-9d27-74bb598zzzzc/v2.0/'azure_ad_jwks_uri='https://exampletenant.b2clogin.com/exampletenant.onmicrosoft.com/B2C_1_app_sign_in/discovery/v2.0/keys'payload=verify_jwt(token='<AZURE_JWT_TO_VERIFY_HERE>',valid_audiences=[azure_ad_app_id],issuer=azure_ad_issuer,jwks_uri=azure_ad_jwks_uri,verify=True,)print(payload){'aud':'b74cd13f-8f79-4c98-b748-7789ecb1111d5','auth_time':1591800638,'emails':['bob@example.com'],'exp':1591804238,'family_name':'Exp Admin','given_name':'Richard','iat':1591800638,'iss':'https://exampletenant.b2clogin.com/90867afa-24e7-40e9-9d27-74bb598zzzzc/v2.0/','nbf':1591800638,'sub':'e07bbc53-b812-4572-9edc-4b5d4ac88447','tfp':'B2C_1_app_sign_in','ver':'1.0'}If something goes wrong, one of the below exceptions will be raised:# If the token is found to be invalid.
