    "description": "# Jacquard - Connect API\n\nConnect is an API to give access to Jacquard services. Using connect clients can access basic reference data, submit results, and utilise the continuous optimisation service.\n\n## Glossary\n\n- Account – the holder for a given company\n    \n- Project – a collection of Jacquard experiments linked\n    \n- Campaign – an individual split test containing generated language variants\n    \n- User – users are granted access to a specified list of projects within Jacquard users can access any campaigns that were created within the projects that they have access to\n    \n- Access tokens\n    \n\n```\nTo access the Connect API you will need a valid bearer token passed in the Authorization header of your requests. There are 2 types of tokens: Access tokens come in 2 types, user and server. User tokens are generated automatically by a user logging into the Jacquard UI. Server access tokens are generated by Jacquard and provided to clients on an ad hoc basis.  \nJacquard provides a facility to generate access tokens these tokens are granted permissions to access specified projects within an account when accessing the API. There could either be a single token with access to the entire account EG for a centralised email ops team. Or multiple tokens with access to specific projects for de-centralised email ops teams.  \nUser access tokens can be refreshed in the Jacquard UI and will expire after 2 weeks. Server access tokens do not have an expiry setting.\n\n ```\n\nContact Support:  \nEmail: [support@jacquard.com](https://mailto:support@jacquard.com)",
