The members' data API is a Play app that manages and retrieves supporter attributes associated with a user.
It runs on https://members-data-api.theguardian.com/.

theguardian.com website is the biggest single consumer of members-data-api, specifically the /user-attributes/me endpoint, which it uses to determine both ad-free (when user has a digital subscription or supporter plus or a newspaper product) and if we should hide 'support messaging/asks' (banner, epic, header/footer support buttons etc).

It would be unnecessary to hit members-data-api on every single page view, so instead it uses cookies to regulate how often calls are made. The gu_user_features_expiry contains a timestamp for the 'earliest' point it would be allowed to call members-data-api again, and is updated whenever it does call members-data-api to 'now + 24hours'.

Various things from the /user-attributes/me response are stored in cookies, to be used on each render...

• GU_AF1 the 'ad-free' cookie which is set to a timestamp for 'now + 48hours' if the contentAccess.digitalPack = true
• gu_hide_support_messaging is set to true if showSupportMessaging = false in the response
• gu_action_required_for is set to the value of alertAvailableFor in the response, and is used to control the display of the 'payment failure' banner
• gu_paying_member = contentAccess.paidMember in the response
• gu_digital_subscriber = contentAccess.digitalPack in the response
• gu_recurring_contributor = contentAccess.recurringContributor in the response
• gu_one_off_contribution_date = oneOffContributionDate in the response

• DCR dotcom-rendering/src/web/lib/contributions.ts
• Dotcom
  • frontend/static/src/javascripts/projects/common/modules/commercial/user-features.ts
  • frontend/blob/master/common/app/templates/inlineJS/blocking/applyRenderConditions.scala.js

User attributes (which products a user currently holds) are served from three sources

1. The SupporterProductData-[STAGE] DynamoDB table - This table is populated by a scheduled extract from Stripe (Guardian Patrons only) and Zuora (digital and print subscriptions & recurring contributions)
2. The contributions-store-[STAGE] Postgres database (one off contributions only)
3. The mobile purchases api (in-app purchases only)

1. You will need to have dev-nginx installed.

2. Follow the nginx steps for identity-platform.

3. Follow the identity-frontend configuration steps.

4. Then run ./setup.sh in nginx/.

5. Add the following entries to your hosts file:

127.0.0.1   profile.thegulocal.com
127.0.0.1   members-data-api.thegulocal.com

1. Get Janus credentials for membership.

2. Download the config
   (you may need to brew install awscli to get the command.)
   aws s3 cp s3://gu-reader-revenue-private/membership/members-data-api/DEV/members-data-api.private.conf /etc/gu/ --profile membership

1. Get Janus credentials for membership.

2. (optional) Create an ssh tunnel to the CODE one-off contributions database:

   1. Clone https://github.com/guardian/contributions-platform
   2. From the contributions-platform project, Run ./contributions-store/contributions-store-bastion/scripts/open_ssh_tunnel.sh -s CODE (requires marauder)
   3. If you need to close your tunnel and didn't make a note of the process number you can run ps aux | grep amazonaws.com to find the process number. The output will look something like this username 1693 0.0 0.0 34153208 952 ?? Ss 4:20pm 0:00.00 ssh -i /private/var/folders/yv/dbtm9psd5ddbjm_lvcjm9zf1vdng_j/T/security_ssm-scala_temporary-rsa-private-key.tmp -f machine.eu-west-1.compute.amazonaws.com -L 5432:contributions-store-code.address.rds.amazonaws.com:5432 -N -o IdentitiesOnly yes -o ExitOnForwardFailure yes where 1693 is the process number. You can close the tunnel with kill 1693.

3. Ensure an nginx service is running locally. You can run dev-nginx restart-nginx to do this.

The /me endpoints can either use the GU_U and SC_GU_U from the Cookie request header or Bearer authorisation header. To get either of these you will need to sign in to the identity frontend.

To authenticate and get a bearer token from identity (recommended)

1. Follow this identity thread to set up PostMan https://chat.google.com/room/AAAAFdv9gK8/kxmrtiVjtRs/

To run identity locally for browser based access (not recommended)

1. Start up a local Identity service by running script make dev in the gateway repo.
2. Go to https://profile.thegulocal.com/signin.

1. To start the Members' data API service run ./start-api.sh.
   The service will be running on 9400.

2. go to https://members-data-api.thegulocal.com/user-attributes/me. If you get a 401 response, it probably means your Identity credentials have expired.
   Renew them by following the steps in Identity frontend local sign in

3. As of 22/04/2022 the https://members-data-api.thegulocal.com/user-attributes/me endpoint should work correctly if your set up is correct. Other endpoints (/healthcheck, /user-attributes/me/mma-membership) may not work correctly due to upstream dependencies.

run sbt and then test

Identity frontend is split between new (profile-origin) and old (profile), which is the identity project in frontend. Only profile uses the membership-attribute-service. Make sure that it's pointing at your local instance.

membership-attribute-service is installed as systemd service via .deb package.

Application instances allow SSH via SSM tunnel, not via port 22,

1. Get fresh Janus credentials
2. Find instance prism -f instanceName attribute code
3. 1ssm ssh -x -i i-123456 --profile membership`

To enable fine metrics for all http calls to external services (Zuora Rest and SOAP, Salesforce, etc), set this in config (either application.conf or s3://gu-reader-revenue-private/membership/members-data-api/DEV/members-data-api.private.conf):

use-fine-metrics=true

When set, calls to all methods / endpoints will be logged as metrics.
