API development and integration is the work of connecting systems that were never designed to talk to each other, so information moves between them automatically rather than being exported, re-keyed, and reconciled by hand.
Let's TalkData moves between systems on its own, which removes the effort and the transcription errors together.
A change in one place appears in the others, so you stop discovering that two systems disagree.
The most common source of bad data is a person retyping it, and an integration removes that step entirely.
With integration points already in place, connecting the next system is smaller work than the last one.
This is one part of our custom web application development work. Engagements rarely stay in one box: a platform rollout turns into something custom, and both then need looking after. That is why our software development and implementation practice treats implementation, custom development, and ongoing support as one continuous piece of work rather than three separate vendors.
