@ronaldocuevasgarcia , Please note that ionic is out of support, anything provided here is best effort. Were you using previously using the JWT token for REST API call? Here are some things to take note - For the SDK authentication, you will need a Meeting SDK App - For REST API, you will need an OAuth or S2S OAuth App. - The current minimum version of SDK support is 5.12.2. The last version of ionic provided was bundled with 5.7.6 ---

I use jwt rest api, so how can I continue creating sessions in ionic ? or can it no longer be done? ---

You can no longer create meetings within the SDK 1. REST API to do things such as Create Meeting: Use **OAuth App Type** or **Server to Server OAuth App Type** 2. SDK Authentication: Use **Meeting SDK App Type** , Client ID and Client Secret 3. Minimum Version: You need to use SDK Versions 5.12.2 and above, if not it will not work. ---

@ronaldocuevasgarcia , I’m not able to help with the upgrading as we do not support ionic anymore.
