Worked on improving the stability of the DataDog/datadog-api-client-go repository by addressing a critical issue in the sanitization of On-Call Paging configuration keys. Focused on aligning these keys with the class_name format used in API templates, the work involved updating both Jinja2 template files and Go configuration code to prevent misconfigurations in user deployments and API responses. This correction reduced downstream errors and support tickets related to On-Call Paging. Leveraged skills in API development, code generation, and configuration management to resolve the divergence between configuration keys and templates, ultimately enhancing the reliability and maintainability of the Go API client.
