Update Global Variable

Update the value of an existing global variable by its name. Only value can be changed — to modify dataType, isSecret, or canReset, delete and recreate the variable.

Update global variable by name

patch

Update the value of an existing global variable.

checksum header is required — must match the server's current checksum for the variable. Obtain it from the Create response or GET /dev/variable/{name} → data.checksum. If it does not match, the update is rejected.

Only value can be updated through this endpoint. To change dataType, isSecret, or canReset, delete and recreate the variable.

On success: response data includes the updated variable with a new checksum — store it for any subsequent update or delete.

Checksum (required)

The checksum must be sent as a request header. Obtain the current checksum from:

• Create response (data.checksum), or

• Get global variable by name (data.checksum) — most reliable.

If the checksum does not match the server's current state, the update is rejected.

On success, the response returns the updated variable with a new checksum — store it before calling update or delete again.
