1 -Developers can extend the Collaboratory capabilities by providing applications to its community of users.
2 -
3 -This guide describes the steps to make this possible.
4 -
5 -== Becoming a contributor ==
6 -
7 -The first step is for you to **become a contributor**. Contributors can register and manage applications within the Community Apps Catalogue.
8 -
9 -Send an email to [[support@humanbrainproject.eu>>path:mailto:support@humanbrainproject.eu]] with a short summary of your intentions.
10 -
11 -The support team will apply the permissions to your user: your account will be upgraded with developers privileges the next time you will login.

22 -
23 -== Creating your OpenID Connect client ==
24 -
25 -The steps to create an OpenID Connect client are the following:
26 -
27 -1. get an access token from the `developer` client
28 -1. use the token to call the create endpoint
29 -1. save your registration access token for further modifications of your client
30 -
31 -=== Fetching your developer access token ===
32 -
33 -==== some h4 ====
34 -
35 -Getting your developer token is done in one simple step: authenticate against the developer client with the password grant.
36 -
37 -This can be achieved with this sample shell script:
38 -
39 -{{code language="bash"}}
40 -# Gather username and password from user
41 -echo '\nEnter your username' && read clb_dev_username &&
42 -echo '\nEnter your password' && read -s clb_dev_pwd &&
43 -
44 -# Fetch the token
45 -curl -X POST https://iam.humanbrainproject.eu/auth/realms/hbp/protocol/openid-connect/token \
46 - -u developer: \
47 - -d 'grant_type=password' \
48 - -d "username=${clb_dev_username}" \
49 - -d "password=${clb_dev_pwd}" |
50 -
51 -# Prettify the JSON response
52 -json_pp;
53 -
54 -# Erase the credentials from local variables
55 -clb_dev_pwd='';clb_dev_username=''
56 -{{/code}}
57 -
58 -The response will be similar to:
59 -
60 -{{code language="json"}}
61 -{
62 - "access_token": "eyJhbGci...",
63 - "expires_in": 108000,
64 - "refresh_expires_in": 14400,
65 - "refresh_token": "eyJhbGci...",
66 - "token_type": "bearer",
67 - "not-before-policy": 1563261088,
68 - "session_state": "0ac3dfcd-aa5e-42eb-b333-2f73496b81f8",
69 - "scope": ""
70 -}
71 -{{/code}}
72 -
73 -Copy the "access_token" value, you will need if for the next step.
74 -
75 -=== Creating the client ===
76 -
77 -You can now create clients by sending a JSON representation to a specific endpoint:
78 -
79 -{{code language="bash"}}
80 -# Set your developer token
81 -clb_dev_token=...
82 -
83 -# Send the creation request
84 -curl -X POST https://iam.humanbrainproject.eu/auth/realms/hbp/clients-registrations/default/ \
85 - -H "Authorization: Bearer ${clb_dev_token}" \
86 - -H 'Content-Type: application/json' \
