Hi !

You must call the POST method on the `userTask` resource of the [Bonita REST API](https://documentation.bonitasoft.com/bonita/2021.1/bpm-api#_execute_a_task_with_contract): `/API/bpm/userTask/:userTaskId/execution`

NOTE: as your form is not in the Bonita webapp context, you’ll need to:

1. [Enable CORS](https://documentation.bonitasoft.com/bonita/2021.1/enable-cors-in-tomcat-bundle) on the Bonita server
2. [Handle the authentication to the Bonita server](https://documentation.bonitasoft.com/bonita/2021.1/rest-api-authentication#_login_to_bonita) using the proper credentials
3. Retrieve the relevant `userTaskId` to execute (maybe passing it as an url parameter in the external form ?)
4. Make sure the task is assigned to user before executing it or use the `assign=true` URL parameter
