What can you build with Todoist REST API?

Todoist REST API is a Company API. Developers commonly use company APIs for:

enriching CRM records with company firmographics
building lead-generation and prospecting tools
verifying business identity and registration details
monitoring competitors and market intelligence
powering B2B data enrichment pipelines

Bearer token. Your app exchanges credentials for a short-lived token, then sends it as an Authorization header. Tokens expire, so your code needs to handle renewal. Todoist REST API is free to use up to a usage limit, making it a low-risk choice to experiment with.
