In IBM API Connect, an app is typically associated with a single Client ID and secret to maintain a unique identity and secure access to APIs. Each app is expected to use this unique Client ID and secret for authentication and authorization purposes. Therefore, only one Client ID and secret pair is allowed per app, and additional Client IDs and secrets cannot be requested or generated for the same app.

In IBM API Connect, the sequence of execution for global policies and API assembly is crucial, especially in cases where the process fails. If the process fails while executing the post-request, the execution order is as follows:

Pre-request global policy: This is the first to execute before the API request is processed.

API assembly: After the pre-request global policy, the API assembly (which contains the core business logic of the API) is executed.

Post-request global policy: This is executed after the API assembly has been processed, but if the process fails here, the post-request global policy may not complete.

Error global policy: When the failure occurs, the error global policy is triggered to handle any errors that occur during the execution of the API, specifically after the failure in the post-request.

Thus, if a failure occurs in the post-request global policy, the subsequent step would involve invoking the Error global policy to handle the failure. The execution order is as follows:

Pre-request global policy

API assembly

Post-request global policy (failure occurs here)

Error global policy

This is the correct flow based on API execution steps in the presence of global policies.

The Consumer APIs should be used to register users in the Developer Portal, create applications, and subscribe to APIs. These APIs provide the necessary endpoints and functionality for Consumers to interact with the Developer Portal and manage their API usage.

Packaging Format: Gateway extensions in IBM API Connect v10.0.3 are packaged as .zip files. This format is used to bundle all necessary files and configurations required for the extension.

Upload Process: These .zip files are then uploaded to the Gateway through the API Manager interface. The API Manager handles the deployment and integration of these extensions into the Gateway.

Documentation Reference: According to the IBM Certified Solution Implementer - API Connect v10.0.3 documentation, the correct packaging format for Gateway extensions is .zip files1.

When creating an OpenAPI 3.0 API in IBM API Connect v10.0.3 that is secured by basic authentication, API Key, or OAuth, it is essential that the security-schema-name follows a specific pattern. This pattern is required to ensure proper validation and application of the security definitions according to the OpenAPI 3.0 specification. The security definitions help define the methods of authentication that are enforced for accessing the API endpoints, which is crucial for maintaining the API's integrity and security.

API Analytics provides insight into API usage. It offers a comprehensive set of tools and metrics to monitor and analyze API performance, usage patterns, and user behavior. This information is valuable for understanding API adoption, identifying trends, and making data-driven decisions to improve API management.

In IBM API Connect v10.0.3, OpenID Connect (OIDC) is a widely used authentication mechanism that allows clients to verify the identity of users based on the authentication performed by an authorization server. API Connect supports various OIDC providers for portal access to integrate with third-party identity providers. Out of the box, API Connect v10.0.3 comes with support for Azure Active Directory (Azure AD) and IBM Cloud as pre-configured OIDC providers.

Azure AD is one of the most commonly used OIDC providers, especially in enterprise environments using Microsoft's cloud services.

IBM Cloud Identity and Access Management (IAM) also provides built-in OIDC support within the IBM ecosystem, making it a natural integration point for users of IBM Cloud services.

These built-in integrations simplify the configuration and management of OIDC providers without requiring additional custom configuration.

Developer User Experience with API Connect

To find all Products in a specific Provider organization using the API Connect CLI, you can use the following command:

products:list --realm [providerOrg]

This command will list all Products that belong to the specified Provider organization. You can then use additional filtering options to find Products based on specific criteria, such as their creation date or status.
