--* **repository**: a URL to a public repository so users can access the source code of your app.
++== Creating your OpenID Connect client ==
--Click on **Save**. Your app is now registered and waiting for users to install it!
++The steps to create an OpenID Connect client are the following:
--=== Installing your app in a collab ===
++1. get an access token from the `developer` client
++1. use the token to call the create endpoint
++1. save your registration access token for further modifications of your client
--1. In order to install your app, you need to navigate to a collab where you have either the **editor** or **admin** role.
--1. Click on **Create** at the top right to create a new entry in the navigation pane under the current wiki page. Enter a title for this instance of your app and select **Community App** in the right selector.
--1. Click on **Create**. You will be presented with the Community App Catalogue. The apps you will see are the public apps and the ones for which you are a maintainer.
--1. Select your app and click on **Save and View**.
++=== Fetching your developer access token ===
--You should now see your app in your collab just as other users will see it.
++Getting your developer token is done in one simple step: authenticate against the developer client with the password grant.
--== Getting your app instance context ==
++This can be achieved with this sample shell script:
--Instances of your apps will be installed by collab owners in many different collabs. In order to let you customise the user experience based on its context, the Collaboratory will automatically pass query parameters to your app:
++{{code language="bash"}}
++# Gather username and password from user
++echo '\nEnter your username' && read clb_dev_username &&
++echo '\nEnter your password' && read -s clb_dev_pwd &&
--* **##clb-collab-id##**: the unique, human-readable identifier of the collab.
--* ##**clb-doc-path**##: the (relative) path to your app instance within the collab. If your app is at the root of a collab, this value will be empty.
--* ##**clb-doc-name**##: the name of the document where your app instance is installed.
--* ##**clb-drive-id**##: the unique identifier of the drive of the collab. This id is required if you want to fetch or store documents within the drive of the collab.
++# Fetch the token
++curl -X POST https://iam.humanbrainproject.eu/auth/realms/hbp/protocol/openid-connect/token \
++  -u developer: \
++  -d 'grant_type=password' \
++  -d "username=${clb_dev_username}" \
++  -d "password=${clb_dev_pwd}" |
++
++# Prettify the JSON response
++json_pp;
--== App settings ==
++# Erase the credentials from local variables
++clb_dev_pwd='';clb_dev_username=''
++{{/code}}
--The app settings are the values the collab owners can modify to change the behaviour of your app within their collabs.
++The response will be similar to:
--=== Writing settings ===
++{{code language="json"}}
++{
++    "access_token": "eyJhbGci...",
++    "expires_in": 108000,
++    "refresh_expires_in": 14400,
++    "refresh_token": "eyJhbGci...",
++    "token_type": "bearer",
++    "not-before-policy": 1563261088,
++    "session_state": "0ac3dfcd-aa5e-42eb-b333-2f73496b81f8",
++    "scope": ""
++}
++{{/code}}
--The Collaboratory comes with a mechanism to let your app store its settings directly in the Collaboratory.
++Copy the "access_token" value, you will need if for the next step.
--In order to do that, your app needs to use the [[postMessage javascript API>>https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage]] to send the settings to be stored in the Collaboratory. The settings are key/value pairs as in the example below.
++=== Creating the client ===
--{{code language="javascript"}}
--window.parent.postMessage({
--    topic: '/clb/community-app/settings',
--    data: {
--        setting1: 'setting 1 value',
--        setting2: 'setting 2 value',
--        // ...
--        // reload: false // avoid page reload on settings change
--    }}, 'https://wiki.ebrains.eu');
++You can now create clients by sending a JSON representation to a specific endpoint:
++
++{{code language="bash"}}
++# Set your developer token
++clb_dev_token=...
++
++# Send the creation request
++curl -X POST https://iam.humanbrainproject.eu/auth/realms/hbp/clients-registrations/default/ \
++  -H "Authorization: Bearer ${clb_dev_token}" \
++  -H 'Content-Type: application/json' \
++  -d '{
++        "clientId": "my-awesome-client",
++        "name": "My Awesome App",
++        "description": "This describes what my app is for end users",
++        "rootUrl": "https://root.url.of.my.app",
++        "baseUrl": "/relative/path/to/its/frontpage.html",
++        "redirectUris": [
++            "/relative/redirect/path",
++            "/these/can/use/wildcards/*"
++        ],
++        "webOrigins": ["+"],
++        "bearerOnly": false,
++        "consentRequired": true,
++        "standardFlowEnabled": true,

++            "contacts": "first.contact@example.com; second.contact@example.com"
++        }
++    }' |
++
++# Prettify the JSON response
++json_pp;
  {{/code}}
--=== Reading settings ===
++In case of success, the endpoint will return its representation of your client:
--The Collaboratory will get the settings from its key/value store and pass them to your app through query parameters.
++{{code language="json"}}
++{
++   "defaultClientScopes" : [
++      "web-origins",
++      "roles"
++   ],
++   "redirectUris" : [
++      "/relative/redirect/path",
++      "/these/can/use/wildcards/*"
++   ],
++   "nodeReRegistrationTimeout" : -1,
++   "rootUrl" : "https://root.url.of.my.app",

++   "description" : "This describes what my app is for end users",
++   "notBefore" : 0,

++   "implicitFlowEnabled" : true,
++   "protocol" : "openid-connect",
++   "bearerOnly" : false,
++   "serviceAccountsEnabled" : false
++}
++{{/code}}
--== Creating your OpenID Connect client ==
++Among all the attributes, you should securely save:
--See the instructions [[here>>doc:Collabs.collaboratory-community-apps.Community App Developer Guide.1\. Registering an OIDC client.WebHome]].
++* your client **secret** ("secret" attribute): it is needed by your application to **authenticate to the IAM server** when making backend calls
++* your client **registration access token** ("registrationAccessToken"): you will need it to authenticate when **modifying your client in the future**
++
++=== Modifying your client ===
++
++Update your client with a PUT request:
++
++{{code language="bash"}}
++# Set your registration token and client id
++clb_reg_token=...
++
++# Update the client
++curl -X PUT https://iam.humanbrainproject.eu/auth/realms/hbp/clients-registrations/default/my-awesome-client \
++  -H "Authorization: Bearer ${clb_reg_token}" \
++  -H 'Content-Type: application/json' \
++  -d '{
++        "clientId": "my-awesome-client",
++        "redirectUris": [
++            "/relative/redirect/path",
++            "/these/can/use/wildcards/*",
++            "/a/new/redirect/uri"
++        ]
++    }' |
++
++# Prettify the JSON response
++json_pp;
++{{/code}}
++
++ Note that your need to provide your client id both in the endpoint URL and within the body of the request.
++
++{{warning}}
++/!\ **  Each time you modify your client, a new registration access token will be generated. You need to track of your token changes to keep access to your client.   **/!\
