Transient Token Format

The transient token is issued as a JSON Web Token (JWT) (RFC 7519). A JWT takes the form of a string, consisting of three parts separated by dots:

Header

Payload

Signature

This example shows a JWT:

xxxxx.yyyyy.zzzzz

The payload portion of the token is a Base64 URL encoded JSON string and contains various claims. This example shows a payload:

{
    "iss": "Flex/07",
    "exp": 1597084897,
    "type": "gda-0.1.1",
    "iat": 1597083997,
    "jti": "1C26VZRFEIQMOO5H0504KH47I0AM2IZFC43V5L541HBLN9COI3L75F3194E196A1"
