The GraphQL versus REST debate often gets treated as a single technology choice, when it is really a question about who uses your API and how their needs change over time. Enterprise systems, especially ones with many internal modules and outside integration partners, usually need both, serving different people for different reasons. Here is the plan we use when deciding which to reach for, and when.
If an outside partner needs to create a purchase order, check its status, and cancel it, a REST style endpoint with predictable actions and a steady response shape is easier to write down, cache, and debug than the same thing built in GraphQL. The simple shape of REST, one resource, one address, predictable actions, is actually a strength when the resource itself is simple and the people using it are outside systems that value steadiness over flexibility.
The case for GraphQL becomes strong the moment you have several different front ends, a web dashboard, a mobile app, a partner's own system, each needing a different piece of the same underlying records. Without GraphQL, you either send everything and let each consumer throw away what it does not need, or you end up maintaining a growing pile of custom REST endpoints, one for each shape of consumer. GraphQL lets each consumer ask for exactly what it needs from one single address, which matters a great deal once you are supporting more than two or three different client applications against the same backend.
Enterprise systems often need bulk actions, creating fifty purchase orders from one import file, updating the status of a whole batch of records at once, and neither plain REST nor plain GraphQL handles this well on its own. What works in practice is a dedicated bulk operations endpoint, one address that accepts a clearly typed batch of actions along with a marker for what kind of bulk action this is, and passes each item through the exact same checking and saving logic the single record path already uses. Building bulk actions as a thin wrapper around logic that is already proven is far safer than writing a second, separate version of that logic that slowly drifts away from the version everyone has already tested.
Most API design focuses on pull, where a consumer asks you for data. Enterprise integrations, especially with outside systems like insurers, imaging providers, or supplier platforms, increasingly need push as well, telling someone the moment something changes. Treat outgoing webhooks as part of your API plan from day one. Sign every payload, log every outgoing call with enough detail to replay it later, and make a failed delivery visible to an actual person rather than letting it disappear quietly. A webhook system nobody is watching is worse than having no webhook system at all, since partners will assume it is working.
Most of the enterprise platforms we have built end up running REST for steady outside integrations, GraphQL for internal use across several client applications, and a purpose built bulk and webhook layer for the work that does not fit cleanly into either approach. The mistake to avoid is picking one approach out of loyalty and forcing every single use case through it regardless of fit.
