Methods and systems are provided for client controlled transaction processing. The method may be carried out at a transaction server, and include: receiving a transaction request from a transaction initiator and allocating a transaction identifier to the transaction; receiving notification of the number of jobs to be completed in the transaction; maintaining a transaction status indicating the current status of the transaction; receiving job status updates from one or more participants processing the jobs included in the transaction and updating a transaction record reflecting the status of each of the jobs included in the transaction; updating the transaction status when required based on the job status updates of the jobs included in the transaction; and receiving and responding to transaction status polling to provide a current transaction status, where the transaction status polling originates from the transaction initiator and the participants processing the jobs.

Client controlled transaction processing involving a plurality of participants

A method, apparatus, system, and computer program product for dynamically selecting transmission data formats for communicating data. A request for a server application sent from a client application is received by receiving, by a computer system. The request includes first data in a first transmission data format and identifies a set of transmission data formats acceptable to the client application. A determination is made by the computer system as whether the first transmission data format is supported. A response from the server application with second data in a selected transmission data format in the set of transmission data formats by the computer system in response to the first transmission data format being supported.

Dynamically switchable transmission data formats in a computer system

Methods and systems may provide for technology to determine dynamic path information and encoded type information associated with an application programming interface (API) and automatically generate a language-independent API definition based on the dynamic path information. In one example, the language-independent API definition is generated without reliance on source code annotations.

Automatically building a web API definition from a microservice or web application

Method and system are provided for handling request data with type safety in a remote service. The method includes providing a data structure, the data structure comprising a set of entries, each entry matching an incoming request type with a function for handling the request, the function defining a set of parameters. The method includes receiving an incoming request for a service from a remote client, wherein the request includes request data. The method includes using the data structure and identifying an entry for the incoming request by matching the request data to an incoming request type of an entry. The method includes converting the incoming request into a set of parameters using a software construct of the matching function identified in the entry, wherein the software construct comprises the matching function and associated in-scope local variables; and running the function using the converted parameters.
