This is an example of using BankID with CURL to achieve Connect (login), and Identify (userinfo and profile).
Companion Postman Collection is also available for you to follow along.
- You will need the CURL HTTP client. You can also import CURL calls into Postman.
- We will be using OIDC Debugger for handling redirects
- Configure
https://oidcdebugger.com/debugredirect_uri for your application in BankID
- Configure
Our examples will use the following keys:
- Implicit Flow: Client Id =
191ede14-968a-4cca-b2c9-6f2a1f595515 - Code Flow: Client Id =
23bb49e7-97e8-4cb8-8dc0-15db1486b788, Client Secret =SRH8KlLbppd4iT391M5lh-rWN6cGruhV1qaSi8Jo0kE2h8DrjSMERzYnCIpIMH5dsFPiW8yI5DC5GjzVH6Qqow
Get access token for a Single Page Application or similar client which cannot securely store Client Secret.
First, we will need to construct authorization URL. You can copy the authorization URL from the "Examples" section in Credentials tab in your application in the Developer Portal. Do note the client_id query parameter, which you will have to update to the client id issued to you.
Once you have the authorization URI constructed, open it in a browser and copy the access token
https://oidc.sandbox.bankid.cz/auth?client_id=191ede14-968a-4cca-b2c9-6f2a1f595515&redirect_uri=https%3A%2F%2Foidcdebugger.com%2Fdebug&scope=profile.birthnumber%20profile.phonenumber%20profile.zoneinfo%20profile.gender%20openid%20profile.titles%20profile.name%20profile.birthplaceNationality%20profile.locale%20profile.idcards%20profile.maritalstatus%20profile.legalstatus%20profile.email%20profile.paymentAccounts%20profile.addresses%20profile.birthdate%20profile.updatedat&response_type=token&state=BankID%20works%21&nonce=2b13acea-ea17-4399-ab2e-f748bd636ce4&prompt=login&display=page&acr_values=loa2Get access token for a server side application in which you can securely store the Client Secret.
Construct and authorization URL in the same way as for Implicit Flow, but make sure to configure your application to use Code Flow on the Developer Portal and use response_type=code query parameter.
Once you have the authorization URI constructed, open it in a browser and copy the code token
https://oidc.sandbox.bankid.cz/auth?client_id=23bb49e7-97e8-4cb8-8dc0-15db1486b788&redirect_uri=https%3A%2F%2Foidcdebugger.com%2Fdebug&scope=profile.birthnumber%20profile.phonenumber%20profile.zoneinfo%20profile.gender%20openid%20profile.titles%20profile.name%20profile.birthplaceNationality%20profile.locale%20profile.idcards%20profile.maritalstatus%20profile.legalstatus%20profile.email%20profile.paymentAccounts%20profile.addresses%20profile.birthdate%20profile.updatedat&response_type=code&state=BankID%20works%21&nonce=fd68ae30-15d5-4937-be1f-f0a5ac071422&prompt=login&display=page&acr_values=loa2To get access token from code token, copy the code from OIDC Debugger and use it in following CURL call
