# Auth0 - Mobile App Backend Implementation

## Notes

### Today 
* Login return CRM token 
* Used for further communication/information 

### Future 
* Login returns success 
* We need to request an AuthO token 
* Refresh AuthO token if expired 
* Straight string replacement?
* Where all are we using CRM/AuthO tokens? 

#### CustomersInfo APIs
* Consumer Mobile team created backend CustomersInfo service 
* Deployed in prod, not taking traffic. Still need to validate end-to-end in QA.
* This will be integrated into user-service.

#### Device Registration

* This is already complete and live in production.
* If client is sending CRM token then it can be removed.

## APIs

### ESB Calls

* GET_CUSTOMER
* GET_POINT_LIST
* GET_POINT_SUMMARIES
* GET_REWARDS_LIST
* GET_ATTRIBUTES
  
## Architecture

### Overview

* Implement replacement calls in existing user-service (running in PCF)
* User service will call modernized (Auth0-based) calls provided by My Account team.
    * When call comes in, if it has Auth0 authorization header and bearer token then we will call Auth0. If it has CRM token then we call legacy.
* We can get migration metrics directly from user-service.
* Pivot Akamai calls from ESB to Apigee
    * Create new Akamai property?
* Implement API proxies in Apigee

#### Calls to be implemented in User Service

* CustomersInfo `https://gateway.dcsg.com/ws/v1/crm/customersinfo` <sup>(0)</sup>
* CustomersMe `https://crmprod.api.dcsg.com/customerapi/mkt/crm/v1/customers/me` <sup>(1)</sup>

* Apple Wallet (a.k.a. Passbook): `https://www.MyScoreCardAccount.com/crmcdn/getloyaltycardpassbook.ashx?sub_account=&account_type_id=1&token=`
* ~~Forgot Username (Android only?) `https://gateway.dcsg.com/ws/v1/crm/accounts/send/username` (via Nate: The Accounts/send/username will not exist going forward because the username is the email address)~~
* Reward Grace Period?

<sup>(0)</sup> Coarse-grained call that makes five sub-calls
<sup>(1)</sup> Called by customersinfo logic
<sup>(2)</sup> Called only as part of CustomersInfo
<sup>(3)</sup> Called as part of CustomersInfo, and dedicated client calls.

## Open Questions
- [x] Nate to check if attributes call is working properly
    * sub-call of customersinfo
    * determines if user is a gold member
- [x] Nate to share Get_Rewards_List replacement
    * (part of customersinfo call replacements)
- [x] Nate will provide URLs to replace customer APIs (including "me" APIs)
- [x] Opt-Ins need fixed/moved (who owns this?)
    * SMS, e-rewards, etc. 
    * My Prefs
    * this is part of /customers/me
    * there is also a PUT for saving prefs
- [x] Need to get passbook separately (best approach for this?)
    * Apple Wallet
    * customersinfo returns passbook url 
    * they will no longer return url
    * short term fix possible
    * work with Nate
- [x] Need to align with Whitney on API to get reward grace period 
    * app has 10 day grace period hardcoded
    * should get it from crm via some call
- [x] Nate and Trevor to figure out network level (public vs private and network hops) 
    * they use AP01 and VP01 
    * implement circuit breaker in our services (common lib)
- [x] Check with Whitney on Get_Point_List MOVE points
     * New call only shows transaction-based points
- [ ] Need to align on sunset date (based on app migration?)
- [x] Get API documentation 
    * swagger
- [ ] Close the loop on Certona call 
    * uses master customer id

## Legacy User Migration
* Credentials populated in Auth0 since holiday 2020.
* Legacy users (not in Auth0) will be signed out.
* Forgot Password flow will migrate.

## Auth0 Frontend Stories

* Sign In
* Sign Out
* Points Summary
    * Call MyAccount API directly
    * Will be part of customer info too 
* Refresh Access Token
* Customer Info (will be pivoted to backend service in PCF)
* Get Account Tier (Loyalty Info)
    * Will be part of customer info, no separate call required from client
* My Preferences Page (will be pivoted to backend service in PCF)
* Get Points List
    * Call MyAccount API directly
    * Will be part of customer info too 
* Create Account
    * No longer need to call login after Create Account
* Auto Shop Sign In
    * more info needed from ecomm teams
* Legacy User Migration
* Forgot password
    * Related to legacy user migration
    * Will be used to silently migrate logged-in users


## Raw Notes from Alignment Meeting (5/22)

URLs and Swagger for new calls in QA and Prod
Jordan walked us through examples using the MyAccount page and Chrome Dev Tools. 

Attributes call working properly?
Jordan showed us the loyaltyinformation call which provides us the gold status.

Passbook
Apple Wallet. Consumer Mobile team will investigate level of effort to take this over.

Opt-Ins
Jordan showed us the Account Settings page. We will call directly to External Comms for the Opt-Ins.

Reward Grace Period (Whitney)
This might become a Firebase config.

Get_Point_List MOVE points (Whitney)
Not a high priority but Whitney expects it to be picked up in time for Fathers Day.

Actions Call - 50 Bonus Points
New work for account team to create this call.

More Notes

/identity - main user info call
/loyaltyinformation - scorecard gold
Rewards (past and active, activeonly=true)

Points summary
	- Reward amount is the current reward balance

Points List
	- Move Points is missing (expected in time for Fathers Day)

Order History - use customer order

My Prefs -- identity service for addresses,etc. And calls into athlete service.

VP01 is primary for most services, Identity Service primary AP01.
