What a connection may do: read, drafts, write
Every connection has an allowed access. Read only lets only GET through, Prepare drafts everything except DELETE, Read and write everything. Flow checks this itself, before the call leaves — even when a workflow or AI Colleague tries something else. Here you see a POST refused, then allowed, and a DELETE that is still not allowed with Drafts.
A connection that may only read
Under Connections create a General HTTP API. Allowed access is Read only by default: the safest choice, and enough as long as you only fetch data.
A workflow that wants to create something
An HTTP request step with the method POST through this connection: it wants to create a draft order. Line up the steps, save and run. Flow refuses the call: the connection may only read. The other system sees nothing.
Deleting stays closed
Set the method to DELETE and run. With Prepare drafts Flow refuses every DELETE: a workflow or AI Colleague that goes wrong cannot throw anything away. Only Read and write allows that.
