+The `uint.parse` processor takes a string and parses it as an unsigned integer with the specified `base` and `bitSize`. This processor will return an error if the message being processed is not a string or if the string cannot be parsed into an unsigned integer.
+
+- **type**: `uint.parse`
+- **params**:
+    - **base**: (optional) the base to use for parsing the unsigned integer, defaults to 10
+    - **bitSize**: (optional) the bit size of the unsigned integer to parse, defaults to 64
+
+### Example
+This would parse the string payload as a 32 bit, base 10 unsigned integer and set the payload to that value.
