# Encoded JWT

Your application login endpoint will receive a parameter called JWT, which is a string consisting of three parts:

1.  Encoded JWT Header
2.  JWT Second Part
3.  JWT Third Part

These parts occur in the above order separated by period ('.') delimiters. Each part contains base64url encoded content:
