- [Bulk add, update, or remove carriers in a broker's network](https://developer.truckstop.com/reference/manage-mynetwork.md): Performs batched add, update, and remove operations against the authenticated broker's network. Carriers are identified by DOT number only.  The request is an array of operation groups; each group specifies an action and the DOT numbers it applies to. The response mirrors that structure and, for each operation group, reports the DOT numbers that were affected as well as the DOT numbers that were skipped along with a per-item reason and code.  Each operation result reports DOT numbers in three buckets: `affected` (the action was performed exactly as requested), `adjusted` (the action was performed but altered from what was requested - for example, an Add that would exceed the broker's active-network limit is added to the inactive list instead), and `skipped` (the action was not performed; reason explains why).  Semantics:   * Add - affected are DOT numbers that were not already in the network and     have been added to the active list when `activate` is true or to the     inactive list when `activate` is false. Adjusted are DOT numbers that     were added but placed differently than requested - currently, this     occurs when adding with `activate` true would exceed the broker's     active-network limit, in which case the overflow DOTs are added to     the inactive list and reported here with reason     `OverLimitAddedInactive`. Skipped are DOT numbers already in the     network (AddDuplicate), invalid (InvalidDot), or otherwise not added     (Other). `activate` is required.   * Update - affected are DOT numbers that were in the network and now     appear on the active list when `activate` is true or on the inactive     list when `activate` is false. A carrier already on the target list is     still considered affected. Skipped are DOT numbers not in the network     (UpdateNotFound), invalid (InvalidDot), or otherwise not updated     (Other). `activate` is required.   * Remove - affected are DOT numbers that were in the network and have     been removed from it entirely (no longer on either list). Skipped are     DOT numbers not in the network (RemoveNotFound), invalid (InvalidDot),     or otherwise not removed (Other). `activate` must be omitted or null;     supplying a value results in a 400 response.
