In the given scenario, a rate limiting policy has been applied to the SOAP API and a global error handler is configured to handle HTTP:RETRY_EXHAUSTED errors with a 429 status code. The rate limiting policy will trigger when the client exceeds the allowed quota of API calls. Since the HTTP:RETRY_EXHAUSTED error specifically catches quota exhaustion errors and the error handler is configured to return a 429 status code, the expected HTTP status returned to the client when the quota is exceeded will be 429. This error code indicates that the user has sent too many requests in a given amount of time ("rate limiting").

To hide sensitive data exchanged between API consumers and API implementations while allowing the conversion of tokenized fields back to their original values for other API requests or responses, the best approach is to use tokenization. This involves:

Tokenization Format: Create a tokenization format that will be used to apply a tokenization policy in the API gateway. This format ensures that sensitive fields in message payloads are replaced with tokenized values that maintain a similar format, making them less recognizable as sensitive data.

Tokenization Policy: Apply a tokenization policy in the API gateway that replaces sensitive data with tokenized values.

Detokenization Policy: Apply a corresponding detokenization policy in the API gateway to convert tokenized values back to their original values when required by other APIs.

This method does not require recoding the API implementations and ensures that sensitive data is protected while still being accessible in its original form when necessary.

A major distinguishing characteristic of an application network, according to MuleSoft, is that it is built for change and self-service. An application network connects applications, data, and devices with APIs, enabling self-service access and reuse of assets. This architecture allows organizations to rapidly adapt to changing business needs, fosters innovation, and reduces time to market by empowering different teams to access and integrate systems independently without waiting for centralized IT.
