POC of APIs from B3 - Investor - New Logged Area/Nova Área Logada

B3 API Documentation

• At the moment, this documentation is only available on Portuguese.

The objective of this POC is to execute the healthcheck endpoint of B3 investor certification environment.

In this POC you will find example to:

• Consume one endpoint with two-way SSL connections;
• Generate Trust Store in a Java Key Store (JKS) format from one HTTPS endpoint;
• Generate Key Store in a JKS format from PFX (P12) file;
• Consume HTTP with Microprofile REST Client using:
  • Authorization Bearer in the Header;
  • Trust Store parameters;
  • Key Store parameters.

Fast instructions:

• Obtain the Access Package;
• Create the key store file;
• Write the password of the key store in the application.properties;
• Run the project.

./mvnw quarkus:dev

Access the /TOKEN endpoint passing your client_id and secret to receive the token.

Execute the /api/healthcheck/{token} with the token and recive the success response:

{
  "status": "Sucesso",
  "mensagem": "Autenticação e autorização do usuário 42451170000132 validadas com sucesso."
}

Instructions to execute the B3 certification APIs

Obtain the Access Package

According B3 documentation, first, you have to execute this endpoint:

POST https://apib3i-cert.b3.com.br/api/acesso/autosservico

Passing this body:

{   
    "nome": "Company name",
    "documento": "42451170000132",
    "email": "email@emailcom.br"
} 

"documento" is your company CNPJ (Brazilian code for companies).

You will receive one access package in the email you informed.

Generate your Key Store file - b3_api.jks

Execute the following command to generate the key store file (b3_api.jks):

keytool -importkeystore -srckeystore 42451170000132.p12 -srcstoretype pkcs12 -srcstorepass ABCDEF -destkeystore b3_api.jks -deststoretype jks -deststorepass ABCDEF

These parameters were received in your access package:

• 42451170000132.p12 - your P12 (PFX);
• ABCDEF - your password;

Copy the b3_api.jks file to your src/main/resources folder.

Write the trustStorePassword on the application.properties

In the src/main/resources/application.properties inform the org.acme.B3ApiService/mp-rest/keyStorePassword with the password you received in the access package.

Obtain the Certificate Authority file (CA) - Optional

This is optional, because the b3_cert_api_ca is already present in the resources of this project.

$ openssl s_client -showcerts -connect apib3i-cert.b3.com.br:2443

Copy the content between -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- and save it into a file called b3-cert-api.crt.

Or just use this crt file already created.

Generate your Trust Store file - b3_cert_api_ca.jks - Optional

This is optional, because the b3_cert_api_ca is already present in the resources of this project.

$ keytool -import -alias b3-cert-api -file b3-cert-api.crt -keystore b3_cert_api_ca.jks -storepass B3APICA -noprompt

Copy the b3_cert_api_ca.jks file to your src/main/resources folder.

Quarkus original - poc-b3-investor-api Project

This project uses Quarkus, the Supersonic Subatomic Java Framework.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw compile quarkus:dev

NOTE: Quarkus now ships with a Dev UI, which is available in dev mode only at http://localhost:8080/q/dev/.

Packaging and running the application

The application can be packaged using:

./mvnw package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using java -jar target/quarkus-app/quarkus-run.jar.

If you want to build an über-jar, execute the following command:

./mvnw package -Dquarkus.package.type=uber-jar

The application, packaged as an über-jar, is now runnable using java -jar target/*-runner.jar.

Creating a native executable

You can create a native executable using:

./mvnw package -Pnative

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

./mvnw package -Pnative -Dquarkus.native.container-build=true

You can then execute your native executable with: ./target/poc-b3-investor-api-1.0.0-SNAPSHOT-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/maven-tooling.html.
