The API allows clients to extract data from, or inject data to the Little Big Connection platform. For any question about the API, please contact our support team.\n\n## **** This is an outdated documentation not longer maintained. To find the last version of the API documentation, please go to** [ <b>https://api-doc.elevenvms.com</b>](https://api-doc.elevenvms.com) **\n\n# Usage Limits\n\nTo protect our servers, the following limitations exist:\n\n- One service call per IP at a time; concurrent calls are not allowed\n    \n- The number of service calls is limited to 10 per second\n    \n- The number of daily service calls is limited to 50,000\n    \n\n# Authentication\n\nIn June 2025 we're supporting OAuth2.0 Client Credentials flow to authenticate your API requests.\n\nPreferred authentication method is OAuth2, please contact Support to get your credentials and start using the API.  \nIf you are using BasicAuth, please note that this method is deprecated and will be retired in the future.\n\n## OAuth2.0\n\nThe OAuth2.0 authentication is used to authenticate the user and authorize  \naccess to the API. The client credentials flow is used to obtain an access  \ntoken for the API. The access token must be included in the Authorization  \nheader of each request with the _Bearer_ prefix.\n\nThe access token is valid for the defined time in the response (currently 1 day). After that, you must request a new token.\n\nThe token is obtained by sending a POST request to the token URL with the  \nfollowing parameters:\n\n- grant_type: client_credentials\n    \n- client_id: your_client_id\n    \n- client_secret: your_client_secret\n    \n- audience: external-client-api-v2\n    \n\nThe token endpoints are:\n\nUAT:

[https://api.littlebigconnection.com/oauth/token](https://api.littlebigconnection.com/oauth/token)\n\n## Basic Authentication with PartnerId\n\nYou must provide your credentials and your partner identifier with every  \nrequest.\n\n**Authentication header**\n\n- Username: Email provided by Support\n    \n- Password: Password (or API Key) provided by Support\n    \n\n**Additional header**\n\n- PartnerId: Provided by Support\n    \n\n# Endpoints\n\n**Production server** : [https://api.littlebigconnection.com/](https://api.littlebigconnection.com/)\n\n**UAT server** :
