1. A computer-implemented method, comprising: receiving, by a processor, a first interaction request via a first communications channel for engaging in a first communication with a user device; retrieving, by the processor, an interaction flow document in response to the first interaction request, the interaction flow document including instructions for processing interactions over a plurality of different communications channels; translating, by the processor, the instructions of the retrieved interaction flow document to first instructions compatible with the first communications channel; executing, by the processor, the first instructions for engaging in communication with the user device over the first communications channel; receiving, by the processor, a second interaction request via a second communications channel, the second communications channel being different from the first communications channel; retrieving, by the processor, the interaction flow document in response to the second request; translating, by the processor, the instructions of the retrieved interaction flow document to second instructions compatible with the second communications channel; and executing, by the processor, the second instructions for engaging in communication with the user device over the second communications channel.
