This application uses a Todoist API Token. You can generate one yourself: Todoist Settings > Integrations > Manage Apps Create an application Extract the API Token

Since this application is build using Visual Basic the TLS support is limited. You will need a local http to https proxy to make the connection to the Todoist servers work. Here is my version I forked and made it to work seamlessly in the background https://github.com/renezander030/http-to-https-proxy.

To build this application you will need Visual Basic 6. Fork this repository, clone it and get building!

• to yeokm1 for the proxy portion
• to wqweto for the JSON parser

Everything here built by myself you can use freely any way you like following the MIT-license.
