Abstract: Disclosed are methods, apparatus, systems, and computer readable storage media for interacting with one or more data objects in an online social network. A user interface includes a publisher with a custom action. The custom action is defined in accordance with custom action instructions provided by a first entity via an application programming interface (API). Such custom action instructions may declaratively or programmatically define the data object, the interaction to be performed with the data object, and other attributes associated with the custom action. A user may request to interact with the data object via selection of the custom action by a second entity. Information may be submitted through the publisher to interact with the data object to update a database system associated with the data object. A feed item may be presented for inclusion in the information feed based on the update.

Abstract: The subject matter disclosed herein provides methods for downloading chargeback records. For example, the method may include selecting a merchant from a first web portal associated with a first financial institution and providing first authentication information associated with the merchant and the first financial institution into the first web portal. The method may then include accessing, via the first web portal, first chargeback records for the merchant. Additionally, the method can include selecting the merchant from a second web portal associated with a second financial institution and providing second authentication information associated with the merchant and with the second financial institution into the second web portal. The second authentication information can be different than the first authentication information. Then, the method can include accessing second chargeback records for the merchant.

Abstract: The subject matter disclosed herein provides methods for executing a script to retrieve chargeback records. The method may execute a script for retrieving one or more chargeback records for one or more merchants from one or more web portals of one or more financial institutions. The one or more chargeback records may represent a return of funds to one or more purchasers by the one or more financial institutions. The script may have commands. These commands may navigate a web browser to a web portal associated with at least one financial institution. These commands may also provide authentication information for the at least one merchant into the web portal, access the one or more chargeback records for the at least one merchant, and download the one or more chargeback records. Related apparatus, systems, techniques, and articles are also described.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using reactive programming operators to implement resource pooling. One of the methods includes receiving a first request, from a client application, for a poolable object in a resource pool and maintained by a resource pool manager, wherein the request indicates an operation mode specifying how the resource pool manager should release the poolable object back into the resource pool; generating a plurality of reactive programming operators comprising a poolable object listener publisher and a subscriber that is configured to subscribe to the poolable object listener publisher; evaluating the reactive programming operators in an upstream subscription ordering of the reactive programming operators to obtain a poolable object from the resource pool; and releasing the poolable object back to the resource pool according to the operation mode of the request.

One of the methods includes receiving, by a reactive programming system comprising one or more computers, a reactive programming program defining an ordering of a plurality of operators, the plurality of operators including a subscriber context operator that writes a value to a subscription context for a particular subscriber, wherein the ordering defines an upstream subscription flow ordering from the particular subscriber to a publisher and a downstream data flow ordering from the publisher to the particular subscriber. The operators are evaluated in the upstream subscription flow ordering, including updating a subscription context of each operator with the value written by the subscriber context operator.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for restricting user access to actuators and generating user interface presentations that include data received from the actuators when the user has access. One of the methods includes receiving, by an applications manager component of an application platform in a cloud computing environment, a request by a user to access application information of an application deployed by an application framework installed on the application platform in the cloud computing environment.

The application framework generates a data element for the particular actuator and provides the data element for the particular actuator to the applications manager component. The applications manager component generates a user interface presentation that includes the data element.

Abstract: Systems, methods, and computer program products for distributed validation of credentials are described. Upon receiving a request to perform an action by a user, a system performs a multi-part authentication where in each part, only a portion of authentication information is passed. In a first stage, an application manager of the system receives a first token than specifies partial access rights. In a second stage, a cloud controller of the system requests and receives privileges of the user separately from the first token. An API is presented with a token that only contains the authorities that the API needs, while still allowing validation of cloud controller permissions without having to escalate the user's privileges.
