I have mainly implemented using Layer 7 API Management. Some of the major challenges we were able to meet with a quick release to market methodology. Some of the tasks which we achieved for our customers were: 1. Translation service from SOAP to REST and vice versa. 2. API service to DB (Oracle, MySQL, MSSQL, Snowflake, SAP HANA) -- Created Swagger APIs that were able to perform CRUD operation to the backend API mentioned above and provided routes to query and get data. 3. Integration with Payment gateway service providers to perform (transaction on behalf of the customer with third-party payment gateway service providers white labeled with our APIs ) -- Followed TMF standards for payment gateway integration with the Telcom world. 4. Orchestration of the API. Build multiple microservers and provided orchestration based on route, path, and data in the request and perform actions that would be communicated with multiple APIs and provide a single consolidated response. 5. Provided API-driven security (Oauth 2.0, JWT, SAML, Basic, and a variety of means) to access the API giving the developer the freedom to concentrate only on application/service/microservice and let the gateway handle the threat. 6. Seamless Mutual Authentication allowed good segregation between APIs in the DMZ and internal network.
