Midpoint ID

A unique identifier for each midpoint.
Every midpoint is assigned a globally-unique and immutable identifier on creation - known as a Midpoint ID. Midpoint IDs (commonly writen as MIDs) are used across the Midpoint system to identify and refer to midpoints. 
Midpoint IDs appear in the following places:
In the GraphQL API, the MID is used to identify which midpoint is to be queried or modified. 
On the Midpoint dashboard they are visible from the main screen and the page for each midpoint.
When using the CLI, the MID is found in the midpoint.conf file. Any midpoint commands that make remote changes will use midpoint.conf as their MID.
In contracts that you deploy. 
Midpoint IDs are used on-chain when making a call to a midpoint to identify the target midpoint.
// Make a call to the midpoint with MID of midpointID
IMidpoint(startpointAddress).callMidpoint(midpointID, args);
We strongly recommend checking the MID of incoming requests. See Transact to EVM Function Security for more details.
// Verify that data is being returned for your midpoint
require(midpointID == _midpointId, "Invalid Midpoint ID");
​
During execution of a request, the Midpoint ID can be extracted from any of the source types using the keyword Midpoint_ID.
