The Open Bank Project API
The Open Bank Project is an open-source API for banks that enables account holders to interact with their bank using a wider range of applications and services.
The OBP API supports transparency options (enabling account holders to share configurable views of their transaction data with trusted individuals and even the public), data blurring (to preserve sensitive information) and data enrichment (enabling users to add tags, comments and images to transactions).
The OBP API abstracts away the peculiarities of each core banking system so that a wide range of apps can interact with multiple banks on behalf of the account holder. We want to raise the bar of financial transparency and enable a rich ecosystem of innovative financial applications and services.
Our tagline is: "Bank as a Platform. Transparency as an Asset".
The API supports OAuth 1.0a, OAuth 2, OpenID Connect OIDC and other authentication methods including Direct Login.
The API documentation is best viewed using the OBP API Explorer or a third-party tool that has imported the OBP Swagger definitions.
If you want to run your own copy of API Explorer II, see here
OBP instances support multiple versions of the API simultaneously (unless they are deactivated in config)
To see the status (DRAFT, STABLE or BLEEDING-EDGE) of an API version, look at the root endpoint. For example, /obp/v2.0.0/root
or /obp/v3.0.0/root
.

This project is dual licensed under the AGPL V3 (see NOTICE) and commercial licenses from TESOBE GmbH.
The project uses Maven 3 as its build tool.
To compile and run Jetty, install Maven 3, create your configuration in obp-api/src/main/resources/props/default.props
and execute:
mvn install -pl .,obp-commons && mvn jetty:run -pl obp-api
In case the above command fails try the next one:
export MAVEN_OPTS="-Xss128m" && mvn install -pl .,obp-commons && mvn jetty:run -pl obp-api
Note: How to run via IntelliJ IDEA
-
In
obp-api/src/main/resources/props
create atest.default.props
for tests. Setconnector=mapped
. -
Run a single test. For instance, right-click on
obp-api/test/scala/code/branches/MappedBranchProviderTest
and select "Run Mapp"... -
Run multiple tests: Right-click on
obp-api/test/scala/code
and select Run. If need be:Goto Run / Debug configurations Test Kind: Select All in Package Package: Select code Add the absolute /path-to-your-OBP-API in the "working directory" field You might need to assign more memory via VM Options. For example:
-Xmx1512M -XX:MaxPermSize=512M
or
-Xmx2048m -Xms1024m -Xss2048k -XX:MaxPermSize=1024m
Ensure your
test.default.props
has the minimum settings (seetest.default.props.template
).Right-click
obp-api/test/scala/code
and select the Scala Tests in the code to run them all.Note: You may want to disable some tests not relevant to your setup e.g.: set
bank_account_creation_listener=false
intest.default.props
.
- See
pom.xml
for test configuration. - See http://www.scalatest.org/user_guide.
Set memory options:
export MAVEN_OPTS="-Xmx3000m -Xss2m"
Run one test:
mvn -DwildcardSuites=code.api.directloginTest test
Run all tests and save the output to a file:
export MAVEN_OPTS="-Xss128m" && mvn clean test | tee obp-api-test-results.txt
If you use Ubuntu (or a derivate) and encrypted home directories (e.g. you have ~/.Private), you might run into the following error when the project is built:
uncaught exception during compilation: java.io.IOException
[ERROR] File name too long
[ERROR] two errors found
[DEBUG] Compilation failed (CompilerInterface)
The current workaround is to move the project directory onto a different partition, e.g. under /opt/
.
Docker images of OBP API can be found on Dockerhub: https://hub.docker.com/r/openbankproject/obp-api - pull with docker pull openbankproject/obp-api
.
Props values can be set as environment variables. Props need to be prefixed with OBP_
, .
replaced with _
, and all upper-case, e.g.:
openid_connect.enabled=true
becomes OBP_OPENID_CONNECT_ENABLED=true
.
The default database for testing etc is H2. PostgreSQL is used for the sandboxes (user accounts, metadata, transaction cache). The list of databases fully tested is: PostgreSQL, MS SQL and H2.
Set DB options in the props file:
db.driver=org.h2.Driver
db.url=jdbc:h2:./obp_api.db;DB_CLOSE_ON_EXIT=FALSE
In order to start H2 web console go to http://127.0.0.1:8080/console and you will see a login screen. Please use the following values: Note: make sure the JDBC URL used matches your Props value!
Driver Class: org.h2.Driver
JDBC URL: jdbc:h2:./obp_api.db;AUTO_SERVER=FALSE
User Name:
Password:
Once Postgres is installed (On macOS, use brew
):
-
psql postgres
-
Create database
obpdb
; (or any other name of your choosing). -
Create user
obp
; (this is the user that OBP-API will use to create and access tables etc). -
Alter user obp with password
daniel.says
; (put this password in the OBP-API Props). -
Grant all on database
obpdb
toobp
; (So OBP-API can create tables etc.) -
Then, set the
db.url
in your Props:db.driver=org.postgresql.Driver db.url=jdbc:postgresql://localhost:5432/obpdb?user=obp&password=daniel.says
-
Then, restart OBP-API.
Postgres needs to be compiled with SSL support.
Use OpenSSL to create the files you need.
For the steps, see https://www.howtoforge.com/postgresql-ssl-certificates.
In short, edit postgresql.conf
:
ssl = on
ssl_cert_file = '/etc/YOUR-DIR/server.crt'
ssl_key_file = '/etc/YOUR-DIR/server.key'
And restart Postgres.
Now, this should enable SSL (on the same port that Postgres normally listens on) - but it doesn't force it.
To force SSL, edit pg_hba.conf replacing the host entries with hostssl
.
Now in OBP-API Props, edit your db.url
and add &ssl=true
. For example:
db.url=jdbc:postgresql://localhost:5432/my_obp_database?user=my_obp_user&password=the_password&ssl=true
Note: Your Java environment may need to be set up correctly to use SSL.
Restart OBP-API, if you get an error, check your Java environment can connect to the host over SSL.
Note: You can copy the following example files to prepare your own configurations:
/obp-api/src/main/resources/logback.xml.example
->/obp-api/src/main/resources/logback.xml
(try TRACE or DEBUG)./obp-api/src/main/resources/logback-test.xml.example
->/obp-api/src/main/resources/logback-test.xml
(try TRACE or DEBUG).
There is a gist/tool which is useful for this. Search the web for SSLPoke. Note this is an external repository.
For example:
-
https://gist.github.com/4ndrej/4547029
or
-
git clone https://github.com/MichalHecko/SSLPoke.git . gradle jar cd ./build/libs/ java -jar SSLPoke-1.0.jar www.github.com 443
Successfully connected
java -jar SSLPoke-1.0.jar YOUR-POSTGRES-DATABASE-HOST PORT
You can add switches. For example, for debugging:
java -jar -Dhttps.protocols=TLSv1.1,TLSv1.2 -Djavax.net.debug=all SSLPoke-1.0.jar localhost 5432
To import a certificate:
keytool -import -storepass changeit -noprompt -alias localhost_postgres_cert -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_73.jdk/Contents/Home/jre/lib/security/cacerts -trustcacerts -file /etc/postgres_ssl_certs/server/server.crt
To get a certificate from the server / get further debug information:
openssl s_client -connect ip:port
The above section is work in progress.
In the API's props file, add the ID of your user account to super_admin_user_ids=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
. User Id can be retrieved via the "Get User (Current)" endpoint (e.g. /obp/v4.0.0/users/current) after login or via API Explorer (https://github.com/OpenBankProject/API-Explorer) at /#OBPv3_0_0-getCurrentUser
.
Super users can give themselves any entitlement, but it is recommended to use this props only for bootstrapping (creating the first admin user). Use this admin user to create further privileged users by granting them the "CanCreateEntitlementAtAnyBank" role. This, again, can be done via API Explorer (/#OBPv2_0_0-addEntitlement
, leave bank_id
empty) or, more conveniently, via API Manager (https://github.com/OpenBankProject/API-Manager).
To populate the OBP database with sandbox data:
- In the API's props file, set
allow_sandbox_data_import=true
. - Grant your user the role
CanCreateSandbox
. See the previous section on how to do this. - Now, post the JSON data using the payload field at
/#2_1_0-sandboxDataImport
. An example of an import set of data (JSON) can be found here. - If successful you should see this result
{ "success": "Success" }
and no error message.
- set the status of HttpOnly and Secure cookie flags for production, uncomment the following lines of
webapp/WEB-INF/web.xml
:
<session-config>
<cookie-config>
<secure>true</secure>
<http-only>true</http-only>
</cookie-config>
</session-config>
We use 9 to run the API in production mode.
-
Install java and jetty9.
-
jetty configuration
-
Edit the
/etc/default/jetty9
file so that it contains the following settings:NO_START=0 JETTY_HOST=127.0.0.1 #If you want your application to be accessed from other hosts, change this to your IP address JAVA_OPTIONS="-Drun.mode=production -XX:PermSize=256M -XX:MaxPermSize=512M -Xmx768m -verbose -Dobp.resource.dir=$JETTY_HOME/resources -Dprops.resource.dir=$JETTY_HOME/resources"
-
In obp-api/src/main/resources/props create a
test.default.props
file for tests. Setconnector=mapped
. -
In obp-api/src/main/resources/props create a
default.props file
for development. Setconnector=mapped
. -
In obp-api/src/main/resources/props create a
production.default.props
file for production. Setconnector=mapped
. -
This file could be similar to the
default.props
file created above, or it could include production settings, such as information about the Postgresql server if you are using one. For example, it could have the following line for Postgresql configuration.db.driver=org.postgresql.Driver db.url=jdbc:postgresql://localhost:5432/yourdbname?user=yourdbusername&password=yourpassword
-
Now, build the application to generate
.war
file which will be deployed on the jetty server:cd OBP-API/ mvn package
-
This will generate OBP-API-1.0.war under
OBP-API/target/
. -
Copy OBP-API-1.0.war to
/usr/share/jetty9/webapps/
directory and rename it to root.war -
Edit the
/etc/jetty9/jetty.conf
file and comment out the lines:etc/jetty-logging.xml etc/jetty-started.xml
-
Now restart jetty9:
sudo service jetty9 restart
-
You should now be able to browse to
localhost:8080
(oryourIPaddress:8080
).
portal
=> OBP-API as a portal i.e. without REST API.apis
=> OBP-API as an APIs app i.e. only REST APIs.apis,portal
=> OBP-API as portal and apis i.e. REST APIs and web portal.
-
Edit your props file(s) to contain one of the next cases:
server_mode=portal
server_mode=apis
server_mode=apis,portal
In case it is not defined, the default case is the 3rd one. For example,
server_mode=apis,portal
.
Most internal OBP model data access now occurs over Akka. This is so the machine that has JDBC access to the OBP database can be physically separated from the OBP API layer. In this configuration we run two instances of OBP-API on two different machines and they communicate over Akka. Please see README.Akka.md for instructions.
For SSL encryption we use JKS keystores. Note that both the keystore and the truststore (and all keys within) must have the same password for unlocking, for which the API will stop at boot up and ask for.
-
Edit your props file(s) to contain:
kafka.use.ssl=true keystore.path=/path/to/api.keystore.jks truststore.path=/path/to/api.truststore.jks
For SSL encryption we use jks keystores. Note that keystore (and all keys within) must have the same password for unlocking, for which the API will stop at boot up and ask for.
-
Edit your props file(s) to contain:
jwt.use.ssl=true keystore.path=/path/to/api.keystore.jks keystore.alias=SOME_KEYSTORE_ALIAS
A props key value, XXX, is considered encrypted if has an encryption property (XXX.is_encrypted) in addition to the regular props key name in the props file e.g:
- db.url.is_encrypted=true
- db.url=BASE64URL(SOME_ENCRYPTED_VALUE)
The Encrypt/Decrypt workflow is :
- Encrypt: Array[Byte]
- Helpers.base64Encode(encrypted)
- Props file: String
- Helpers.base64Decode(encryptedValue)
- Decrypt: Array[Byte]
1st, 2nd and 3rd step can be done using an external tool
-
Export the public certificate from the keystone:
keytool -export -keystore /PATH/TO/KEYSTORE.jks -alias CERTIFICATE_ALIAS -rfc -file apipub.cert
-
Extract the public key from the public certificate:
openssl x509 -pubkey -noout -in apipub.cert > PUBKEY.pub`
-
Get the encrypted
propsvalue
like in the following bash script (usage./scriptname.sh /PATH/TO/PUBKEY.pub propsvalue
):#!/bin/bash echo -n $2 |openssl pkeyutl -pkeyopt rsa_padding_mode:pkcs1 -encrypt -pubin -inkey $1 -out >(base64)
You can obfuscate passwords in the props file the same way as for jetty:
-
Create the obfuscated value as described here: https://www.eclipse.org/jetty/documentation/9.3.x/configuring-security-secure-passwords.html.
-
A props key value, XXX, is considered obfuscated if has an obfuscation property (
XXX.is_obfuscated
) in addition to the regular props key name in the props file e.g:db.url.is_obfuscated=true
db.url=OBF:fdsafdsakwaetcetcetc
Please refer to the Code Generation for links.
Please refer to the Custom Webapp for links.

We support rate limiting i.e functionality to limit calls per consumer key (App). Only New Style Endpoins
support it. The list of they can be found at this file: https://github.com/OpenBankProject/OBP-API/blob/develop/obp-api/src/main/scala/code/api/util/NewStyle.scala.
There are two supported modes:
- In-Memory
- Redis
It is assumed that you have some Redis instances if you want to use the functionality in multi-node architecture.
We apply Rate Limiting for two types of access:
- Authorized
- Anonymous
To set up Rate Limiting in case of anonymous access edit your props file in the following way:
user_consumer_limit_anonymous_access=100, In case isn't defined default value is 60
Te set up Rate Limiting in case of the authorized access use these endpoints:
GET ../management/consumers/CONSUMER_ID/consumer/call-limits
- Get Call Limits for a ConsumerPUT ../management/consumers/CONSUMER_ID/consumer/call-limits
- Set Call Limits for a Consumer
In order to make it work edit your props file in next way:
use_consumer_limits=false, In case isn't defined default value is "false"
redis_address=YOUR_REDIS_URL_ADDRESS, In case isn't defined default value is 127.0.0.1
redis_port=YOUR_REDIS_PORT, In case isn't defined default value is 6379
The next types are supported:
- per second
- per minute
- per hour
- per day
- per week
- per month
If you exceed the rate limit per minute for instance you will get the response:
{
"error": "OBP-10018: Too Many Requests.We only allow 3 requests per minute for this Consumer."
}
and response headers:
X-Rate-Limit-Limit → 3
X-Rate-Limit-Remaining → 0
X-Rate-Limit-Reset → 22
Description of the headers above:
X-Rate-Limit-Limit
- The number of allowed requests in the current period.X-Rate-Limit-Remaining
- The number of remaining requests in the current period.X-Rate-Limit-Reset
- The number of seconds left in the current period.
Please note that first will be checked per second
call limit then per minute
, etc.
Info about rate limiting availability at some instance can be found over next API endpoint: https://apisandbox.openbankproject.com/obp/v3.1.0/rate-limiting. The response we are interested in looks like this:
{
"enabled": false,
"technology": "REDIS",
"service_available": false,
"is_active": false
}
Webhooks are used to call external URLs when certain events happen. Account Webhooks focus on events around accounts. For instance, a webhook could be used to notify an external service if a balance changes on an account. This functionality is a work in progress!
There are 3 API endpoints related to webhooks:
POST ../banks/BANK_ID/account-web-hooks
- Create an Account WebhookPUT ../banks/BANK_ID/account-web-hooks
- Enable/Disable an Account WebhookGET ../management/banks/BANK_ID/account-web-hooks
- Get Account Webhooks
In order to enable an OIDC workflow at an instance of OBP-API portal app(login functionality) you need to set up the following props:
## Google as an identity provider
# openid_connect_1.client_secret=OYdWujJl******_NXzPlDI4T
# openid_connect_1.client_id=883**3244***-s4hi72j0rble0iiivq1gn09k7***tdci.apps.googleusercontent.com
# openid_connect_1.callback_url=http://127.0.0.1:8080/auth/openid-connect/callback

# openid_connect_2.access_type_offline=true
# openid_connect_2.button_text = Yahoo
Please note in the example above you MUST run OBP-API portal at the URL: http://127.0.0.1:8080
In order to enable an OAuth2 workflow at an instance of OBP-API backend app you need to set up the following props:
# -- OAuth 2 ---------------------------------------------------------------------------------
# Enable/Disable OAuth 2 workflow at a server instance
# In case isn't defined default value is false
# allow_oauth2_login=false
# URL of Public server JWK set used for validating bearer JWT access tokens
# It can contain more than one URL i.e. list of uris. Values are comma separated.
# If MITREId URL is present it must be at 1st place in the list
# because MITREId URL can be an appropirate value and we cannot rely on it.
# oauth2.jwk_set.url=http://localhost:8080/jwk.json,https://www.googleapis.com/oauth2/v3/certs
# ------------------------------------------------------------------------------ OAuth 2 ------
OpenID Connect is supported.
Tested Identity providers: Google, MITREId.
Example for Google's OAuth 2.0 implementation for authentication, which conforms to the OpenID Connect specification
allow_oauth2_login=true
oauth2.jwk_set.url=https://www.googleapis.com/oauth2/v3/certs
API versions may be marked as "STABLE", if changes are made to an API which has been marked as "STABLE", then unit test FrozenClassTest
will fail.
- modify request or response body structure of APIs
- add or delete APIs
- change the APIS'
versionStatus
from or to "STABLE"
If it is required for a "STABLE" api to be changed, then the class metadata must be regenerated using the FrozenClassUtil (see how to freeze an API)
- Run the FrozenClassUtil to regenerate persist file of frozen apis information, the file is
PROJECT_ROOT_PATH/obp-api/src/test/resources/frozen_type_meta_data
- push the file
frozen_type_meta_data
to github
There is a video about the detail: demonstrate the detail of the feature
The same as Frozen APIs
, if a related unit test fails, make sure whether the modification is required, if yes, run frozen util to re-generate frozen types metadata file. take RestConnector_vMar2019
as an example, the corresponding util is RestConnector_vMar2019_FrozenUtil
, the corresponding unit test is RestConnector_vMar2019_FrozenTest

OpenJDK 11 is available for download here: https://jdk.java.net/archive/.
ResourceDoc#exampleRequestBody and ResourceDoc#successResponseBody can be the follow type
- Any Case class
- JObject
- Wrapper JArray: JArrayBody(jArray)
- Wrapper String: StringBody("Hello")
- Wrapper primary type: IntBody(1), BooleanBody(true), FloatBody(1.2F)...
- Empty: EmptyBody
Example:
resourceDocs += ResourceDoc(
exampleRequestBody= EmptyBody,
successResponseBody= BooleanBody(true),

)
An additional language can be added via props supported_locales
Steps to add Spanish language:
- tweak the property supported_locales = en_GB to
supported_locales = en_GB,es_ES
- add file
lift-core_es_ES.properties
at the folder/resources/i18n
Please note that default translation file is lift-core.properties
