Abstract: Technologies are described herein for a payments portal. A payments portal can be configured to support payments by generating and embedding widgets in webpages hosted by merchant sites associated with a marketplace. The widgets can provide specific payment functionality for users, thereby providing consistent payment experiences across merchant sites without updating the merchant sites. The widgets can be dynamic or static. Interactions with the widgets can cause a browser displaying the widgets to access data hosted by the payments portal and/or other systems, devices or services in communication with the payments portal.

Abstract: Examples of systems and methods are described for managing payment transaction requests. A request for payment may be received and then routed to one or more payment processors. For a given request, more than one payment processor may be used. The particular payment processor selected for processing the payment may be based on a decision rule that is associated with the more than one payment processor. A decision engine may utilize the decision rule, select a payment processor, and process the payment with the selected payment processor.

Abstract: Techniques are described for migrating data from a first table to a second table while transforming at least one characteristic of the data. Characteristics transformed may include one or more of an encryption key or method, a table schema, a data structure, or a storage infrastructure. Migration may be performed in two or more phases. A first phase may migrate and transform a majority of the data, such as data that is older than a certain threshold age. A second phase may migrate and transform the remaining, newer data. A status table may indicate which tables are active and are to be written to and read from during data writing and data consuming processes. Moreover, embodiments support data replication across multiple regions.
